Patent Application
20190070086
The present application relates to perfume raw materials, perfumes, perfume delivery systems and consumer products comprising such perfume raw materials, perfumes and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfumes, perfume delivery systems and consumer products.
Consumer products may comprise one or more perfumes and/or perfume delivery systems that can provide a desired scent to such product and/or a situs that is contacted with such a product and/or mask an undesirable odor. While current perfumes and perfume delivery systems provide desirable odors, consumers continue to seek products that have scents that may be longer lasting and that are tailored to their individual desires—unfortunately consumers become habituated to perfume raw materials (PRMs) and perfumes. As a result, ever increasing amounts of such PRMs and/or perfumes are required to achieve the same effect or the consumer must switch to a different product and/or perfume for a significant period of time to reverse such habituation.
While not being bound by theory, Applicants believe that habituation is a phenomenon that is grounded in the consumer's physiology, in that the body is attempting to avoid having its sense smell from being overwhelmed by any one stimulus after repeated chronic exposure of said stimulus. This defense mechanism is likely a primal, darwanistic defense mechanism. In short, Applicants recognized that the source of habituation problem likely laid in evolution. As a result, Applicants looked to odors that may be associated with danger as Applicants believed that the evolutionary path of those who became habituated to such odors would have been cut short. Surprisingly, Applicants found that certain chemical moieties that are associated with conditions that may be detrimental to or important in sustaining life, are not subject to the habituation phenomenon. Based on this recognition, Applicants identified perfume raw materials, and developed perfumes, perfume delivery systems and consumer products comprising such perfume raw materials, perfumes and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products that are not as susceptible to habituation.
The present application relates to perfume raw materials, perfumes, perfume delivery systems and consumer products comprising such perfume raw materials, perfumes and/or such perfume delivery systems, as well as processes for making and using such perfume raw materials, perfume delivery systems and consumer products.

Air Care Devices
As the perfumes disclosed herein are not habituating, such perfumes may be used without resorting to switching the perfumes as is common in air care devices so that the consumer does not become habituated. The present invention relates to an apparatus for the delivery of a volatile material to the atmosphere. It is contemplated that the apparatus may be configured for use in a variety of applications to deliver volatile materials to the atmosphere. Suitable devices include those devices disclosed in USPA 2012/0228402 A1 and USPA 2010/0308130 A1 both publications which are herein expressly incorporated by reference.
For example, the apparatus may be configured for use with an energized device. An exemplary energized device may be an electrical heating device. More particularly, the device may be an electrical wall plug air freshener as described in U.S. Pat. No. 7,223,361; a battery powered heating device; or other heating devices (e.g. devices powered by chemical reactions such as catalyst fuel systems; solar powered devices, etc.). In such devices, the volatile material delivery engine may be placed next to the heating surface to diffuse the volatile material. The volatile material formula may be adjusted to include an overall lower vapor pressure formula.
The apparatus may also be configured for use with an air purifying system to deliver both purified air and volatile materials to the atmosphere. Non-limiting examples include air purifying systems using ionization and/or filtration technology for use in small spaces (e.g. bedrooms, bathrooms, automobiles, etc.), and whole house central air conditioning/heating systems (e.g. HVAC).
The apparatus may also be configured for use with an aerosol or non-aerosol air spray. In this embodiment, the delivery engine can deliver volatile materials upon user demand or programmed to automatically deliver volatile materials to the atmosphere.
The apparatus may also be configured for use with a fan to deliver volatile materials to the atmosphere.
In one aspect, an apparatus for delivering a volatile material comprising a delivery engine having a liquid reservoir for containing a volatile material comprising a single opening; a rupturable substrate enclosing the single opening; a rupture element; a collection basin in fluid communication with the liquid reservoir upon rupturing the rupturable substrate; and a breathable membrane enclosing the liquid reservoir, rupturable substrate, rupture element, and collection basin is disclosed. The breathable membrane has an evaporative surface area of about 2 cm2 to about 35 cm2 and has an average pore size of about 0.02 microns. The apparatus also comprises a housing for receiving and releasably engaging the delivery system. The housing has a rib for guiding the delivery engine and a notch for compressing the rupture element upon insertion of the delivery engine into the housing.
In one aspect, an air care device that comprises one chamber said chamber comprising a perfume and/or a perfume raw material disclosed herein is disclosed. In one aspect, an air care device that comprises more than one chamber, at least one of said chambers comprising a perfume and/or a perfume raw material disclosed herein is disclosed.
Certain perfume delivery systems, methods of making certain perfume delivery systems and the uses of such perfume delivery systems are disclosed in USPA 2007/0275866 A1. The perfumes and PRMs disclosed herein may be used in such perfume delivery systems. Such perfume delivery systems include:
Polymer Assisted Delivery (PAD): This perfume delivery technology uses polymeric materials to deliver perfume materials. Classical coacervation, water soluble or partly soluble to insoluble charged or neutral polymers, liquid crystals, hot melts, hydrogels, perfumed plastics, microcapsules, nano- and micro-latexes, polymeric film formers, and polymeric absorbents, polymeric adsorbents, etc. are some examples. PAD includes but is not limited to:
Non-polymer materials or molecules may also serve to improve the delivery of perfume. Without wishing to be bound by theory, perfume may non-covalently interact with organic materials, resulting in altered deposition and/or release. Non-limiting examples of such organic materials include but are not limited to hydrophobic materials such as organic oils, waxes, mineral oils, petrolatum, fatty acids or esters, sugars, surfactants, liposomes and even other perfume raw material (perfume oils), as well as natural oils, including body and/or other soils. Perfume fixatives are yet another example. In one aspect, non-polymeric materials or molecules have a CLogP greater than about 2. Molecule-Assisted Delivery (MAD) may also include those described in U.S. Pat. No. 7,119,060.
The choice or use of a situs itself may serve to improve the delivery of perfume. In fact, the situs itself may be a perfume delivery technology. For example, different fabric types such as cotton or polyester will have different properties with respect to ability to attract and/or retain and/or release perfume. The amount of perfume deposited on or in fibers may be altered by the choice of fiber, and also by the history or treatment of the fiber, as well as by any fiber coatings or treatments. Fibers may be woven and non-woven as well as natural or synthetic. Natural fibers include those produced by plants, animals, and geological processes, and include but are not limited to cellulose materials such as cotton, linen, hemp jute, flax, ramie, and sisal, and fibers used to manufacture paper and cloth. Fiber-Assisted Delivery may consist of the use of wood fiber, such as thermomechanical pulp and bleached or unbleached kraft or sulfite pulps. Animal fibers consist largely of particular proteins, such as silk, sinew, catgut and hair (including wool). Polymer fibers based on synthetic chemicals include but are not limited to polyamide nylon, PET or PBT polyester, phenol-formaldehyde (PF), polyvinyl alcohol fiber (PVOH), polyvinyl chloride fiber (PVC), polyolefins (PP and PE), and acrylic polymers. All such fibers may be pre-loaded with a perfume, and then added to a product that may or may not contain free perfume and/or one or more perfume delivery technologies. In one aspect, the fibers may be added to a product prior to being loaded with a perfume, and then loaded with a perfume by adding a perfume that may diffuse into the fiber, to the product. Without wishing to be bound by theory, the perfume may absorb onto or be adsorbed into the fiber, for example, during product storage, and then be released at one or more moments of truth or consumer touch points.
The amine-assisted delivery technology approach utilizes materials that contain an amine group to increase perfume deposition or modify perfume release during product use. There is no requirement in this approach to pre-complex or pre-react the perfume raw material(s) and amine prior to addition to the product. In one aspect, amine-containing AAD materials suitable for use herein may be non-aromatic; for example, polyalkylimine, such as polyethyleneimine (PEI), or polyvinylamine (PVAm), or aromatic, for example, anthranilates. Such materials may also be polymeric or non-polymeric. In one aspect, such materials contain at least one primary amine. This technology will allow increased longevity and controlled release also of low ODT perfume notes (e.g., aldehydes, ketones, enones) via amine functionality, and delivery of other PRMs, without being bound by theory, via polymer-assisted delivery for polymeric amines. Without technology, volatile top notes can be lost too quickly, leaving a higher ratio of middle and base notes to top notes. The use of a polymeric amine allows higher levels of top notes and other PRMS to be used to obtain freshness longevity without causing neat product odor to be more intense than desired, or allows top notes and other PRMs to be used more efficiently. In one aspect, AAD systems are effective at delivering PRMs at pH greater than about neutral. Without wishing to be bound by theory, conditions in which more of the amines of the AAD system are deprotonated may result in an increased affinity of the deprotonated amines for PRMs such as aldehydes and ketones, including unsaturated ketones and enones such as damascone. In another aspect, polymeric amines are effective at delivering PRMs at pH less than about neutral. Without wishing to be bound by theory, conditions in which more of the amines of the AAD system are protonated may result in a decreased affinity of the protonated amines for PRMs such as aldehydes and ketones, and a strong affinity of the polymer framework for a broad range of PRMs. In such an aspect, polymer-assisted delivery may be delivering more of the perfume benefit; such systems are a subspecies of AAD and may be referred to as Amine-Polymer-Assisted Delivery or APAD. In some cases when the APAD is employed in a composition that has a pH of less than seven, such APAD systems may also be considered Polymer-Assisted Delivery (PAD). In yet another aspect, AAD and PAD systems may interact with other materials, such as anionic surfactants or polymers to form coacervate and/or coacervates-like systems. In another aspect, a material that contains a heteroatom other than nitrogen, for example sulfur, phosphorus or selenium, may be used as an alternative to amine compounds. In yet another aspect, the aforementioned alternative compounds can be used in combination with amine compounds. In yet another aspect, a single molecule may comprise an amine moiety and one or more of the alternative heteroatom moieties, for example, thiols, phosphines and selenols. Suitable AAD systems as well as methods of making same may be found in U.S. Pat. No. 6,103,678.
This technology approach uses a cyclic oligosaccharide or cyclodextrin to improve the delivery of perfume. Typically a perfume and cyclodextrin (CD) complex is formed. Such complexes may be preformed, formed in-situ, or formed on or in the situs. Without wishing to be bound by theory, loss of water may serve to shift the equilibrium toward the CD-Perfume complex, especially if other adjunct ingredients (e.g., surfactant) are not present at high concentration to compete with the perfume for the cyclodextrin cavity. A bloom benefit may be achieved if water exposure or an increase in moisture content occurs at a later time point. In addition, cyclodextrin allows the perfume formulator increased flexibility in selection of PRMs. Cyclodextrin may be pre-loaded with perfume or added separately from perfume to obtain the desired perfume stability, deposition or release benefit. Suitable CDs as well as methods of making same may be found in USPA 2006/0263313 A1.
The use of a starch encapsulated accord (SEA) technology allows one to modify the properties of the perfume, for example, by converting a liquid perfume into a solid by adding ingredients such as starch. The benefit includes increased perfume retention during product storage, especially under non-aqueous conditions. Upon exposure to moisture, a perfume bloom may be triggered. Benefits at other moments of truth may also be achieved because the starch allows the product formulator to select PRMs or PRM concentrations that normally cannot be used without the presence of SEA. Another technology example includes the use of other organic and inorganic materials, such as silica to convert perfume from liquid to solid. Suitable SEAs as well as methods of making same may be found in U.S. Pat. No. 6,458,754 B1.
This technology relates to the use of porous zeolites or other inorganic materials to deliver perfumes. Perfume-loaded zeolite may be used with or without adjunct ingredients used for example to coat the perfume-loaded zeolite (PLZ) to change its perfume release properties during product storage or during use or from the dry situs. Suitable zeolite and inorganic carriers as well as methods of making same may be found in USPA 2005/0003980 A1. Silica is another form of ZIC. Another example of a suitable inorganic carrier includes inorganic tubules, where the perfume or other active material is contained within the lumen of the nano- or micro-tubules. Preferably, the perfume-loaded inorganic tubule (or Perfume-Loaded Tubule or PLT) is a mineral nano- or micro-tubule, such as halloysite or mixtures of halloysite with other inorganic materials, including other clays. The PLT technology may also comprise additional ingredients on the inside and/or outside of the tubule for the purpose of improving in-product diffusion stability, deposition on the desired situs or for controlling the release rate of the loaded perfume. Monomeric and/or polymeric materials, including starch encapsulation, may be used to coat, plug, cap, or otherwise encapsulate the PLT. Suitable PLT systems as well as methods of making same may be found in U.S. Pat. No. 5,651,976.
This technology refers to perfume technologies that result from the reaction of perfume materials with other substrates or chemicals to form materials that have a covalent bond between one or more PRMs and one or more carriers. The PRM is converted into a new material called a pro-PRM (i.e., pro-perfume), which then may release the original PRM upon exposure to a trigger such as water or light. Pro-perfumes may provide enhanced perfume delivery properties such as increased perfume deposition, longevity, stability, retention, and the like. Pro-perfumes include those that are monomeric (non-polymeric) or polymeric, and may be pre-formed or may be formed in-situ under equilibrium conditions, such as those that may be present during in-product storage or on the wet or dry situs. Nonlimiting examples of pro-perfumes include Michael adducts (e.g., beta-amino ketones), aromatic or non-aromatic imines (Schiffs Bases), oxazolidines, beta-keto esters, and orthoesters. Another aspect includes compounds comprising one or more beta-oxy or beta-thio carbonyl moieties capable of releasing a PRM, for example, an alpha, beta-unsaturated ketone, aldehyde or carboxylic ester. The typical trigger for perfume release is exposure to water; although other triggers may include enzymes, heat, light, pH change, autoxidation, a shift of equilibrium, change in concentration or ionic strength and others. For aqueous-based products, light-triggered pro-perfumes are particularly suited. Such photo-pro-perfumes (PPPs) include but are not limited to those that release coumarin derivatives and perfumes and/or pro-perfumes upon being triggered. The released pro-perfume may release one or more PRMs by means of any of the above mentioned triggers. In one aspect, the photo-pro-perfume releases a nitrogen-based pro-perfume when exposed to a light and/or moisture trigger. In another aspect, the nitrogen-based pro-perfume, released from the photo-pro-perfume, releases one or more PRMs selected, for example, from aldehydes, ketones (including enones) and alcohols. In still another aspect, the PPP releases a dihydroxy coumarin derivative. The light-triggered pro-perfume may also be an ester that releases a coumarin derivative and a perfume alcohol. In one aspect the pro-perfume is a dimethoxybenzoin derivative as described in USPA 2006/0020459 A1. In another aspect the pro-perfume is a 3′,5′-dimethoxybenzoin (DMB) derivative that releases an alcohol upon exposure to electromagnetic radiation. In yet another aspect, the pro-perfume releases one or more low ODT PRMs, including tertiary alcohols such as linalool, tetrahydrolinalool, or dihydromyrcenol. Suitable pro-perfumes and methods of making same can be found in U.S. Pat. No. 7,018,978 B2.
b.) Sulfur-Containing Pro-Perfume Compound
The embodiments of the perfumes disclosed herein can be used as the perfume component pro-perfume compounds that contain sulfur. The term “pro-perfume compound” herein refers to compounds resulting from the chemical bonding of perfume raw materials (PRMs) with materials that comprise sulfur. The pro-perfume compound can release the original PRM (i.e., pre-converted) upon exposure to a trigger such as water or light or atmospheric oxygen. Suitable methods of making the same can be found in U.S. Pat. No. 7,018,978.

The Degree of Habituation to a perfume, PRM or product comprising such materials, is determined via human panel testing with daily exposures to the scent over a four week period, and is calculated at both the week two and week four time points, relative to the initial baseline time point.
For each exposure panel test, more than 15 panelists are recruited, then exposed to the test scent in a manner, frequency, and concentration indicated by the intended product end use, but including at least one exposure per day every day for four consecutive weeks. The perfume exposure must be sufficient that the panelists can detect the perfume of interest being delivered from the product or perfume delivery system contained within the product. The criteria for recruitment onto the exposure panel requires that panelists be typical consumers of the product in question, who agree to use the scent being tested, are non-smokers, and free of nasal congestion and allergies. The degree of habituation is calculated and reported as the percent change in the Odor Detection Threshold (ODT) value at week 2 and at week 4, versus the initial baseline ODT value. Since the degree of habituation is a relative measure, it accommodates the variation in absolute ODT values which can arise between different testing laboratories.
Raw materials and finished products comprising them may be used together in conjunction in order to determine the degree of habituation. For example, daily exposures to the panelists may involve the use of a finished product while the ODT test measurements may involve the use of the respective neat perfume or PRM. The conditions selected for use in either the daily exposures or in the ODT testing must be applied uniformly across all panelists, and remain unchanged for the entirety of the four week testing period. When the test perfume materials are available in their simple forms i.e., PRM, neat perfume, or fine fragrance, unincorporated into complex products or delivery systems, then the ODT test is to be conducted with these simple forms via an olfactometer, as this is the preferred method. When these simple forms of the test perfume materials are inaccessible for testing, then the ODT test may be conducted with finished products or complex formulations comprising the test perfume materials. Presentation devices other than an olfactometer may be required when conducting the ODT testing on finished products or complex formulations, and may include devices such as sniff cups, headspace chambers and capped bottles, as allowed for in the test method ASTM E679-04 described below.
The ODT value for each panelist is determined at each of three time points the during four week daily exposure period, namely; at initial baseline, at two weeks, and at four weeks. The ODT values are always to be determined in accordance with test method ASTM E679-04 (Standard Practice for Determination of Odor and Taste Thresholds by a Forced-Choice Ascending Concentration Series of Limits) as reapproved in 2011 except, the following replaces the protocol of such test method's Sub-articles 4.4, 8.2 and 8.3.
Sub-article 4.4, Individual best-estimate values of the threshold are derived from the pattern of correct/incorrect responses produced separately by each panelist. The group average ODT value at a given time point is derived by fitting the entire data set from all panelists at that time point to a Log Logistic Regression Model.
Sub-article 8.2, If the concentration range has been correctly selected, it is not necessary that all panelists judge correctly within the range of concentration steps provided. Thus, the representation of the panelists' judgments as in 8.1 need not terminate with two or more consecutive plusses (+).
Sub-article 8.3, Since there is a finite probability that a correct answer will occur by chance alone, it is important that a panelist repeat the test three times. Panelists who fail the test at the highest concentration, are deemed anosmic to the test material and their response is removed from the data set.
Additionally, the following selections are made in accordance with the test method's sub-articles 1.3, 1.4, 1.6, 1.7, and 4.1, and specified here as per sub-article 9.3.
Sub-article 1.3, The threshold is characterized as being a) only detection (awareness) that a very small amount of added substance is present but not necessarily recognizable.
Sub-article 1.4, When the preferred method is being conducted, namely using a simple perfume form presented via olfactometer, then the presentation medium can be an air, pure nitrogen, or a mixture of the two. When testing finished or complex products, alternative presentation media may be used, such as air.
Sub-article 1.6, When the preferred method is being conducted, namely using a simple perfume form presented via olfactometer, then the physical method of presentation is at a rate of 40 L/min.
When testing finished or complex products, alternative presentation devices may be used, including but not limited to sniff cups, headspace chambers or capped bottles.
Sub-article 1.7, Presentation is made to a panel of greater than 15 panelists, who are participating in the daily exposure panel.
Sub-article 4.1, Eight scale steps are used, with each step having an individual predetermined dilution factor suitable for the stimuli being tested, at a temperature of 35° C. PRM or neat perfume stimuli are typically introduced to the olfactometer system in the neat form via a pump syringe. Sometimes a dilution of the stimuli with ethanol is needed.
The group average ODT values from the three time points are used to calculate the degree of habituation. The degree of habituation is reported for 2 specific time points, as the percent change in group average ODT at one time point, relative to the group average ODT at the initial baseline time point. The degree of habituation is determined at the time points of: 2 weeks and 4 weeks, of the four week daily exposure period, using the following formula:
Degree of Habituation (percent change in ODT) at Time X=((Group Average ODT(Time X)−Group Average ODT(Baseline)/Group Average ODT(Baseline)×100
where Time X is either 2 weeks, or 4 weeks, of repeated daily exposure.
A perfume is considered to have an anti-habituation index of:
For a two week test
While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
Example Anhydrous Stick Compositions that Resist Habituation, Excluding Formula IV
With the exception of Formula IV, the formulations defined above contain perfume from table 1 at various levels, optionally using various perfume delivery systems. Formula III contains Perfume from Table 1 contained in a polyacrylate microcapsule, as described above in Polymer Assisted Deliver, Reservoir Systems. Formula VI contained perfume from table 1, as described above in Cyclodextrin Delivery Systems.
Test subjects were recruited for the following study, based on their acceptance of the scent of the products in formulas IV, V, and VI above. Approximately 20 test subjects per usage group were recruited for the study. The test subjects placed in the study were assessed for their baseline threshold intensity according to the Odor Detection Threshold (ODT) method defined above for the perfume of interest that was in the product. Test subjects were placed in three study groups with an antiperspirant/deodorant according to formulas IV, V, and VI and instructed to apply 2 clicks per underarm (approximately 0.4 g per underarm) throughout the four week study period, using no other underarm products throughout the duration of the study. Their Odor Detection Threshold (ODT) was measured again after 2 weeks of usage, and again after 4 weeks of usage. The average Odor Detection Threshold was calculated for each usage group. Results are shown below.
The results indicate that the Odor Detection Threshold increases significantly above baseline (test subjects are less sensitive) for the usage group using Formula IV (comparative perfume) after 4 weeks of usage, indicating habituation. The surprising result is that the Odor Detection Threshold remains below baseline for each usage group using formula V and formula VI that contain the perfume from table 1, indicating that they did not become habituated to the scent of the product over time. Therefore, the perfume used in formula V and VI is has an anti-habituation index of 4 and 3 respectively when tested in a two week test and an anti-habituation index of 4 and 4 respectively when tested in a four week test.
Anhydrous Stick Compositions that Resist Habituation

More specifically, formula VIII containing Perfume 2.A includes a three component perfume accord composed of perfume raw materials containing a thiol moiety. Formula IX containing Perfume 2.B includes a three component perfume accord composed of perfume raw materials containing pyrazine, nitrile and amine moieties. Formula X containing Perfume 2.C includes a three component perfume accord composed of perfume raw materials containing a thiazole moiety. Formula XI containing Perfume 2.D includes a three component perfume accord composed of perfume raw materials consisting of menthol and menthol derivatives.
Approximately 20 test subjects per usage group were recruited for the study. The test subjects placed in the study were assessed for their baseline threshold intensity according to the Odor Detection Threshold (ODT) method defined above for the perfume of interest that was in the product. Test subjects were placed in five study groups with an antiperspirant/deodorant according to formulas VII, VIII, IX, X, and XI and instructed to apply 2 clicks per underarm (approximately 0.4 g per underarm) throughout the four week study period, using no other underarm products throughout the duration of the study. Their Odor Detection Threshold (ODT) was measured again after 2 weeks of usage, and again after 4 weeks of usage. The average Odor Detection Threshold was calculated for each usage group. Results are shown below.
The results indicate that the Odor Detection Threshold remains unchanged for the usage group using Formula VII (comparative perfume) after 4 weeks of usage. The Odor Detection Threshold increases significantly above baseline (test subjects are less sensitive) for the usage group using Formula XI (perfume containing menthol and menthol derivatives) after 4 weeks of usage, indicating habituation. One surprising result is that the base perfume's (Formula VII) anti-habituation index of two (2) from the two week test moved, when antihabituation materials were added (formulations VIII, IX and X) to an anti-habituation indices for such formulas of, 4, 4 and 3 respectively under the two week test when the additional perfume raw materials(s) as specified in Perfume 2.A, Perfume 2.B and Perfume 2.C are added. Another surprising result is that the base perfume's (Formula VII) anti-habituation index of three (3) from the four week test moved, when antihabituation materials were added (formulations VIII, IX and X) to an anti-habituation indices for such formulas of, 4, 4 and 4 respectively under the four week test when the additional perfume raw materials(s) as specified in Perfume 2.A, Perfume 2.B and Perfume 2.C are added. Such materials were a thiol accord, pyrazine-nitrile-amine accord, and thiazole accord.
The above formulations VII, VIII, IX, X, and XI were rated by consumers in a usage test. 10 independent test groups of approximately 20 panelists were instructed to use the product as they normally would. 5 of the test groups, each using one of the formulas VII, VIII, IX, X, and XI were instructed to use the product for a single day, and rate their overall opinion of the product after using the product based on a 5 point scale. (100=Excellent, 75=Very Good, 50=Good, 25=Fair, 0=Poor). Separately, the other 5 test groups, each using one of the formulas VII, VIII, IX, X, and XI were instructed to use the product for a four week period, and rate their overall opinion of the product based on the same 5 point scale defined above. Results indicate that formulas are rated parity after a single day usage, but the resistance to habituation shown in table 5 yields an improved usage rating, only after a four week period.
The formulations defined in Table 8 are various perfume formulations to be used in Formula XII. Seventeen unique formulas were made from Formula XII, each containing 0.9% of one of the perfumes from example number XII.A through XII.Q, as defined in Table 8.
Approximately 20 test subjects per usage group were recruited for the study. The test subjects placed in the study were assessed for their baseline threshold intensity according to the Odor Detection Threshold (ODT) method defined above for the perfume of interest that was in the product. Test subjects were placed in nineteen study groups with an antiperspirant/deodorant and instructed to apply 2 clicks per underarm (approximately 0.4 g per underarm) throughout the four week study period, using no other underarm products throughout the duration of the study. Their Odor Detection Threshold (ODT) was measured again after 4 weeks of usage. The average Odor Detection Threshold was calculated for each usage group. Results are shown below.
The results indicate that the Odor Detection Threshold increases significantly above baseline (test subjects are less sensitive) for the usage group using the formula containing the base perfume PD only, which was void of all sulfur and nitrogen PRM's after 4 weeks of usage, indicating habituation. Surprisingly, all components containing sulfur or nitrogen chemistry showed improvement relative to the control. The data further suggests that molecules containing sulfur or nitrogen having a sulfide moiety, thiazole moiety, oxime moiety, or acetyl group produce the highest resistance to habituation, therefore have the highest anti-habituation index at levels below and above threshold
It is believed that the differences seen from Example 2, in which the base perfume had an anti-habituation index of 3 in the four week test, vs. Example 3, in which the base perfume had significant increase in ODT is beyond what is expected of individual variation among panelists and were related to the difference in perfume level (0.8% vs. 0.9%). Further, it is believed that the base perfume would be habituating, even at a lower perfume level if the test subjects used the product for a longer duration. The addition of sulfur and nitrogen PRM's consistently showed greater resistance to habituation as compared to the control—regardless of perfume level tested.
The formulations defined above contain various perfume formulations. Formula XVII contains Perfume from Table 1. Formula XV and XVI contain comparative perfumes.
Approximately 20 test subjects per usage group were recruited for the study. The test subjects placed in the study were assessed for their baseline threshold intensity according to the Odor Detection Threshold (ODT) method defined above for the perfume of interest that was in the product. Test subjects were placed in three study groups with a body wash according to formulas XV, XVI, and XVII and instructed to use the product daily, as they normally would use their current cleansing product throughout the four week study period, using no other cleansing products throughout the duration of the study. Their Odor Detection Threshold (ODT) was measured again after 2 weeks of usage, and again after 4 weeks of usage. The average Odor Detection Threshold was calculated for each usage group. Results are shown below.
The results indicate that the Odor Detection Threshold increases significantly above baseline (test subjects are less sensitive) for the usage group using Formula XV (comparative perfume A) after 4 weeks of usage, indicating habituation. The surprising result is that the test group using the body wash containing the perfume from table 1 had the lowest degree of habituation after 4 weeks of usage, indicating that they did not become habituated to the scent of the product over time. Therefore, the perfume used in formula XVII is has an anti-habituation index of 0 when tested in a two week test and an anti-habituation index of 4 when tested in a four week test.
