Synergistically-effective compositions comprising zinc ricinoleate or solutions thereof and one or more of the substituted monocyclic organic compounds:
A wide variety of solid, liquid and gaseous functional materials including body deodorants, anti-perspirants, anti-perspirant/body deodorant devices, air fresheners which include air freshening devices, and solid and liquid air freshening and room freshening compositions, room deodorants, herbicides, antiviral compositions, fungicides, bactericides, parasiticides, insecticides, depilatory compositions, bleach compositions, hard surface-cleaning compositions, skin cleansing compositions, anti-microbial nail preparations including anti-fungal nail lacquers, hair setting compositions, hair conditioning compositions, trichological lotions, detergent compositions, soap compositions, sunscreen compositions, fabric stain-removal compositions, fabric softener compositions, fabric conditioning compositions, fabric anti-wrinkle compositions, skin softening compositions, skin texture enhancement compositions, such as line and wrinkle corrective compositions, skin lightening compositions, steam iron aroma compositions including stress relief compositions, candle compositions, plant growth regulating compositions, plant growth stimulating compositions, fertilizer compositions, insect attractant compositions, insect repelling compositions, drain cleaning compositions and molluskicide compositions have been developed that, although useful for their respective purposes, on use thereof emanate odours which are offensive to the human sense of smell.
In addition, a number of defined 3-dimensional spaces the use of which is required for various business and service operations and personal matters including indoor gymnasiums, indoor sporting event arenas, locker rooms, hair salons, nail salons, tanning salons, beauty salons, tattoo parlors, pig pens, chicken coops, cow barn enclosures, horse barn enclosures, indoor fresh fish markets, plant processing factory rooms, clothing dry cleaning rooms, garment laundry interiors, rooms containing in-use animal litter containers, abattoirs, cattle cars, zoo animal pens, morgues, autopsy rooms, lavatories, medical patient care rooms,- hospital wards and dental patient care rooms have continuously prevailing odours which are offensive to the human sense of smell. Such odors which are offensive to the human sense of smell are caused by aliphatic halohydrins, aliphatic amines, aliphatic N-oxides, dialkylamines, cycloaliphatic amines, cycloaliphatic N-oxides, cyclo-olefinic amines, cyclo-olefinic N-oxides, cycloaromatic amines, cycloaromatic N-oxides, hydroxyalkylamines, imine compounds, amide compounds, amino acids, polypeptides, modified antimicrobial proteins, diureides, nitriles, aliphatic mercaptans, cycloaliphatic mercaptans, mercaptoalkanoic acids, mercaptoalkanoic acid esters, aliphatic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, cycloaliphatic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, cyclo-olefinic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, cycloaromatic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, alkali metal sulfites, bisulfites and metabisulfites, isothiocyanates, thiocyanates, dithiocyanates, isothiazolones, isothiazolinones, thiodiazinethiones, halosulfamates, aryl sulfonamides, lower aliphatic carboxylic acids, phenols, phosphines, aliphatic phosphites and phosphonates, cycloaliphatic phosphites and phosphonates, arsines, lower alcohols, lower ketones, hops, hops acids, aryl pyrazoles, oxazolines, isocyanurates, biguanides, extracts of krameria, hydantoins, pyrollidones, pyrollidone carboxylic acids, pyrollidone carboxylic acid esters, nitrophenols, N-substituted aspartic acids and pyrethroids. Compounds of these classes that have unpleasant odours are referred to herein as malodor compounds.
The aforementioned functional materials are known to include and/or have applied thereto or in a 3-dimensional space proximate thereto, fragrance materials that are intended to provide pleasant fragrances which mask the malodor.
In addition, the aforementioned defined 3-dimensional spaces are known to have introduced therein compositions such as fragrance materials that are intended to provide pleasant aromas which mask the malodor present therein and/or introduced thereto.
The masking effect is provided by one of three mechanisms. In the first mechanism, the masking composition components blend with the malodor compound or compounds in an effort to effect formation of a different and more desirable aroma. In the second mechanism the masking composition components are employed in a large quantity and concentration whereby the compound or composition responsible for the malodor is overwhelmed. In the third mechanism, one or more masking composition components overwhelm the compound or composition responsible for the malodor and one or more masking composition components chemically react with the malodor compound or composition thereby effecting formation of a more desirable aroma.
Each of the aforementioned mechanisms have serious disadvantages. Thus, in the case where a fragrance composition is used as a malodor maskant, it will not completely eliminate the perception of malodor and, accordingly, there is a tendency to use increasing quantities and concentrations of fragrance in an effort to eliminate the perception of malodor. Furthermore, the masking effect is an additive effect and so the total odor level in the malodor-masked functional product or in the malodor-masked defined 3-dimensional space is increased by consumption of the fragrance. Even though the fragrance so used may be very pleasant at low concentration, the total odour level in the 3-dimensional space proximate the in-use functional product and the total odour level in the aforementioned defined 3-dimensional space at the relatively high concentrations required to achieve even moderate masking of the malodor will itself be offensive to the human sense of smell.
The prior art contains evidence of a large number of efforts to overcome the aforementioned disadvantages.
Thus, the use of zinc ricinoleate, also known as TEGO Sorb (Goldschmidt A. G. of Essen, Germany) for suppressing malodors is disclosed in U.S. Pat. No. 6,528,047, U.S. Pat. No. 6,592,813, U.S. Pat. No. 4,968,496 and U.S. patent application 2003/007945 A1 published on Jan. 9, 2003. Furthermore the use of one or more of the substituted cyclic organic compounds:
Furthermore the use of zinc ricinoleate in functional substance such as fragrance containing polyamide sticks and packages dispensing same are disclosed in U.S. patent application Ser. No. 10/683,525 filed on Oct. 10, 2003 but no mention is made therein of the use of polyamide sticks for malodor suppression or prevention.
However, nothing in the prior art discloses the synergistically-effective compositions of our invention; or such compositions being used to prevent and/or suppress malodors.
Our invention is directed to a synergistically-effective composition for preventing and/or suppressing malodors comprising:
Preferably, the zinc ricinoleate-containing composition of our invention is a mixture of about 50% by weight of zinc ricinoleate and about 50% by weight of at least one 1-hydroxy-2-ethoxethyl ether of a C12-C14 fatty alcohol.
Our invention is also directed to a process for counteracting a malodor emanating from a solid or liquid malodorous source into a 3-dimensional space proximate said source (e.g., malodorous garbage contained in a polyethylene-fabricated garbage bag) comprising the step of introducing into the 3-dimensional space proximate said source a synergistically-effective malodor-counteracting quantity and concentration of the aforementioned zinc ricinoleate-substituted cyclic organic compound-containing composition of our invention as a single dose, as a continuous dose over a malodor-counteracting period of time, or as periodic doses over a malodor-counteracting period of time whereby the perceived total malodor intensity is substantially reduced or eliminated.
Our invention is also directed to a process for preventing a malodor from emanating from a solid or liquid malodorous source into a 3-dimensional space proximate said source comprising the step of admixing with said source a synergistically-effective malodor-counteracting quantity and concentration of the aforementioned zinc ricinoleate-substituted cyclic organic compound-containing composition of our invention.
More specifically our invention is directed to a process wherein the solid or liquid malodorous source evolving or capable of evolving the malodor is, for example, one of: a herbicide; an antiviral composition; a fungicide; a bactericide; a parasiticide; an insecticide; a depilatory preparation; a bleach composition; a hard surface-cleaning preparation; a skin cleansing composition; an anti-microbial nail preparation; a hair setting composition; a hair conditioning composition; a trichological lotion; a skin lightening composition; a skin softening composition; a skin texture enhancement composition; a detergent composition; a soap composition; a sunscreen composition; a fabric stain removal composition; a fabric softening composition; a fabric conditioning composition; a fabric anti-wrinkle composition; a steam iron aroma composition; a candle composition; a plant growth regulating composition; a plant growth stimulating composition; a fertilizer composition; an insect attractant composition; an insect repelling composition; a drain cleaning composition; a molluskicide composition; an anti-perspirant composition; a body deodorant composition; a body deodorant/anti-perspirant device; a waste-disposal container; an air freshener device and an air freshener composition; and wherein the malodor is caused by, for example, a malodor-causing quantity and concentration of at least one compound selected from the group consisting of malodor compounds as described herein.
In addition, in order to effect delivery of the zinc ricinoleate-substituted cyclic organic chemical composition of our invention to an inanimate laminar surface such as the surface of a polypropylene garbage bag containing malodor-evolving garbage, another aspect of our invention is directed to a malodor-suppressing stick article having a consistently-maintained system-compatible malodor-suppressing composition of our invention and dimensional integrity comprising a stiff, substantially monophasic, thermally-reversible composition comprising:
The terms system-compatible malodor-suppressing composition and system-compatible functional composition are herein intended to mean the malodor-suppressing compositions of our invention and other functional compositions, for example, fragrance compositions which, when made part of the support polymer-zinc ricinoleate/substituted monocyclic organic compound system do not compromise the transparency of the stick article by causing haze or cloudiness, due to, for example, phase separation or synerisis to occur as a result of the composition being admixed with the support polymer-zinc ricinoleate/substituted monocyclic organic compound system of our invention.
The term consistently-maintained malodor-suppressing composition and dimensional integrity is intended herein to mean that when the stick article of our invention is in use in applying a film to an inanimate solid laminar surface, the proportions of the constituents and the chemical properties of the malodor-suppressing composition of our invention and, optionally, other functional composition, such as a fragrance composition that is evolved into the environment on use of the stick article of our invention are substantially identical to the proportions and chemical properties of the constituents originally present in the stick article and originally admixed with the support polymer-zinc ricinoleate/substituted monocyclic organic compound system; and the geometric dimensions thereof with reference to the “x”,“y” and “z” axes on use thereof are substantially identical to the geometric dimensions originally existant in the stick article.
The term, stiff is herein intended to mean that the stick article of our invention is self-supporting and non-flowable at ambient temperatures or less and at ambient pressures, e.g., at temperatures of less than or equal to 35° C. and at pressures of about 1 atmosphere absolute.
The term monophasic is herein intended to mean that the stick article of our invention on use or when not in use exists in one unitary phase without any phase separation resulting from the inclusion in the support polymer-zinc ricinoleate/substituted monocyclic organic compound system of a functional composition, e.g., a malodor-suppressing or preventing composition or an optional fragrance composition.
The term thermally reversible is herein intended to mean that the stick article of our invention retains the original proportions of the constituents of its composition and retains its original physical characteristics and original dimensions on use thereof, and subsequent to use thereof.
Our invention is also directed to packages containing such stick articles, and a process for employing such stick articles whereby an inanimate laminar surface is controllably coated with a thin film of ETPA or ATPA polymer which (a) effects malodor supression at and proximate to said inanimate laminar surface and (b) releases the volatile components of the malodor-suppressing composition at a controllable rate into the environment proximate said inanimate laminar surface and (c) optionally releases aesthetically pleasing fragrance at a controllable rate into the environment proximate said inanimate laminar surface. The coating is effected, for example, by means of manually rubbing an exposed end of the malododour-suppressing stick of our invention onto the said inanimate laminar solid surface, using a package containing a partislly-exposed malodor-suppressing stick article of our invention.
The zinc ricinoleate component of the malodor-suppressing and/or preventing composition of our invention is preferably utilized in combination with a solvent which is at least one ethoxylated C12-C14 fatty alcohol, preferably one or more of a 1-hydroxy-2-ethoxyethyl ether of a C12-C14 fatty alcohol, for example, the 1-hydroxy-2-ethoxyethyl ether of stearyl alcohol in a concentration of greater than 30%, preferably at a concentration of about 50%.
In admixture with the zinc ricinoleate component of the malodor-suppressing and/or preventing compositions of our invention, is one or more of the substituted monocyclic organic chemicals.
A preferred substituted monocyclic organic compound composition useful in combination with the zinc ricinoleate component is a mixture of:
More preferably, the weight ratio of components of the immediately-aforementioned zinc riconoleate-substituted monocyclic organic compound mixture is one where the zinc ricinoleate-containing composition: 1-cyclohexylethan-1-yl butyrate: 1-cyclohexylethan-1-yl acetate: 1-(4′-methylethyl)cyclohexylethan-1-yl propionate is about 2:1:1:1.
Another preferred substituted monocyclic organic compound composition useful in combination with the zinc ricinoleate component is a mixture of:
More preferably, the weight ratio of components of the immediately-aforementioned zinc riconoleate-substituted monocyclic organic compound mixture is one where the zinc ricinoleate-containing composition: 1-cyclohexylethan-1-yl acetate: 1-(4′-methylethyl)cyclohexylethan-1-yl propionate is about 3:1:1.
As stated above, the synergistically-effective compositions of our invention substantially eliminate the perception of malodors, and/or prevent the formation of such malodors while simultaneously refraining from reduction of the perception of pleasant fragrance aromas emanating from the same source or from the proximity of said source. The synergistically-effective zinc ricinoleate-substituted monocyclic organic compound compositions of our invention can be utilized with a vast number of functional products in order to prevent malodors evolved by such functional products during use thereof and/or to suppress malodors evolved by such functional products into the 3-dimensional space proximate the functional products while they are being used.
Examples of such functional products which are compositions, effective specific malodorous ingredients or classes of ingredients contained in and/or emanated from said functional products and exemplary defined air dimensional spaces where such functional products are used, together with U.S. patent references setting forth specific examples of the utilities of such functional products are set forth in the following Table I:
Preferably, the synergistically-effective zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing compositions are employed in compatible solvents prior to the composition being incorporated into functional products. Such compatible solvents are, preferably, 1,2-propylene glycol, and di(1,2-dihydroxypropyl)ether, commonly known as dipropylene glycol or DPG. The range of dilution of the zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing compositions in the compatible solvents is from about 2% to about 50% by weight of the zinc ricinoleate-containing composition of our invention, preferably from about 10% to about 30% and most preferably about 15% by weight of the zinc ricinoleate-containing composition of our invention.
When used in conjunction with malodorous solid or liquid functional products, e.g., soap and detergent compositions, the synergistically effective zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing mixtures of our invention may be employed in a concentration of from about 75 ppm to about 300 ppm based on the weight of the solid or liquid composition preferably from about 100 ppm to about 250 ppm.
When used in conjunction with malodorous gaseous functional products, the synergistically effective zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing mixtures of our invention may comprise from about 1.0 gram/liter to about 5.0 grams/liter, preferably from about 1.5 grams/liter to about 3.0 grams/liter of the air 3-dimensional space which contains the malodor to be counteracted.
As stated above, the functional products with which the zinc ricinoleate-substituted monocyclic organic compound compositions of our invention may be used also may optionally include fragrances, anti-microbial substances, animal repellents, insect attractants, and insect repellents, each of the components of which has a C log10 P in the range of from about 3.0 to about 8.0, without restriction on the molecular weight of each of said components wherein P is the n-octanol/water partition coefficient of the fragrance component. Examples of fragrance/anti-microbial compositions useful in the practice of our invention are set forth in U.S. Pat. No. 6,495,512 and U.S. Pat. No. 6,517,759.
The values of C log10P of many functional product ingredients, for example, fragrance ingredients and/or antimicrobial ingredients, contained in personal treatment compositions and/or cosmetic compositions is discussed in U.S. patent application US 2003/0110682 A1 published on Jun. 19, 2003, U.S. Pat. No. 5,348,667, U.S. Pat. No. 5,652,206 and U.S. Pat. No. 6,528,013. Furthermore, values of log10P have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc., Daylight CIS, Irvine, Calif. However, the log10P values are most conveniently calculated by the “CLOGP” program, also available from Daylight CIS. This program also lists experimental log10P values when they are available in the Pomona92 database. The calculated log10P (Clog10P) is determined by the Hansch and Leo “fragment” approach based on the chemical structure of each perfume ingredient, and takes into account the numbers and types of atoms, the atom connectivity and the chemical bonding. The C log10P values which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental log10P values for the selection of functional ingredients, including perfume ingredients which are useful in the stick articles of our invention.
Specific examples of preferred fragrance components useful in the stick articles of our invention, and the molecular weights and C log10P values of each of said components are set forth in Table II as follows:
As stated above, the zinc ricinoleate-substituted monocyclic organic compound compositions of our invention may be employed in stick articles having an ETPA or ATPA polymeric structure.
Thus, the support polymer used in the stick article of our invention is, in the alternative or in combination (a) at least one ester-terminated polyamide or (b) at least one tertiary amide-terminated polyamide.
Preferable ester-terminated polyamides useful in the practice of our invention are those disclosed in U.S. Pat. No. 5,783,657 and U.S. Pat. No. 6,552,160 and include those ester-terminated polyamides prepared by reacting “x” equivalents of a dicarboxylic acid wherein at least 50% of those equivalents are from polymerized fatty acid, “y” equivalents of ethylenediamine and “z” equivalents of an alcohol which is in the alternative, or in combination cetyl alcohol and/or stearyl alcohol wherein:
More preferably, the ester-terminated polyamide is one of a group having a weight-average molecular weight of about 6000 and a softening point in the range of from 88° C. to 94° C. prepared by reacting “x” equivalents of C36 dicarboxylic acid, ”y” equivalents of ethylenediamine and “z” equivalents of an alcohol which is, in the alternative or in combination cetyl alcohol and/or stearyl alcohol wherein
Most preferable are the mineral oil-free ester terminated polyamides, SYLVACLEAR 100LM, UNICLEAR 100 and UNICLEAR 100V, Arizona Chemical Company, Panama City, Fla.
Preferable tertiary amide-terminated polyamides useful in the practice of our invention are those disclosed in U.S. Pat. No, 6,268,466 and U.S. Pat. No. 6,469,131 and include those tertiary amide-terminated polyamides prepared by reacting “x” equivalents of dicarboxylic acid wherein at least 50% of those equivalents are from polymerized fatty acid, “y” equivalents of ethylenediamine and “z” equivalents of a monofunctional reactant having a secondary amine group as the only reactive functionality wherein
Most preferable are those tertiary amide-terminated polyamides disclosed in Example I of U.S. Pat. No. 6,268,466.
The stick articles of our invention, when used in a preferred manner in the practice of our invention are contained, for example, in a package as illustrated in
Such packages for the stick article of our invention comprise means for supporting the functional substance-providing stick article of our invention such that an end portion of said stick article can be exposed for use, with the means for supporting said stick article including a stick-surrounding member for surrounding the stick article, the stick-surrounding member having an opening such that the stick article can be exposed for use, and a border of the stick-surrounding member forming the opening, said border forming a top end of the supporting means, such that said end portion can be elevated from said means for supporting and can protrude therefrom so as to be exposed for use, said stick article being contained within said stick-surrounding member. Thus for example, the means for elevating includes a screw feed mechanism having an elevator screw such that upon rotation of the elevator screw the stick article is pushed up from the bottom such that the end portion protrudes and is exposed for use. As a second example, the means for elevating is a means for pushing up the stick article so that the end portion protrudes from the means for supporting and is exposed for use.
Furthermore, as stated above, our invention is directed to a process for applying a controllably releasable functional substance such as a perfume composition, an insect repellant composition, an animal repellant composition, an anti-microbial composition, an insect attractant composition and/or an air freshener composition to an inanimate laminar substantially solid surface comprising the steps of providing a package as described supra; exposing for use the end portion of said stick article contained within said package; providing an inanimate laminar substantially solid surface to be treated; and applying the end portion of said stick article contained within said package to a finite area of said laminar substantially solid surface.

The following fragrance composition was prepared:
The following fragrance was prepared:
In each of the following Examples I-IV, fragrance formulation and a mixture in the ratio of 2 parts by weight of a 50% solution of zinc ricinoleate in a 1-hydroxy-2-ethoxyethyl ether of a C12-C14 fatty alcohol, referred to herein as TEGO Sorb Conc. 50:1 part by weight of one or more VEILEX compounds, such as 1-(4′-methylethyl)-cyclohexylethan-1-yl propionate was premixed and added, with stirring to UNICLEAR-100-LM ester-terminated polyamide at a temperature of 40° C. The resulting mixture was then placed into molds designed to produce stick articles which fit into packages as illustrated in
wherein VM is a scaled value representing malodor intensity and VF is a scaled value representing fragrance intensity and pleasantness ) for each of the coatings is set forth in each of the examples; and is in the range of 7.5≦V≦10: Those with skill in the art will appreciate that a higher score is superior to a lower score, for example a score of 10 is superior to a score of 7.5.
The following mixtures were prepared and molded into stick articles as set forth above:
The “V” value of the resulting coatings for each of Examples IA, IB, IC and ID is 9.75. This example demonstrates the improvement of the combination of the TEGO sorb and malodor blocking materials in view of the malodor blocking materials alone.
The following mixtures was prepared and molded into stick articles as set forth above:
The “V” value of the resulting coating for Example IIA is 7.75. The “V” value of the resulting coating for Example IIB is 8.10. This example demonstrates the superiority and the synergism of the combination of the TEGO Sorb when used with a 50:50 mixture of 1-cyclohexylethan-1-yl butyrate and 1-cyclohexylethan-1-yl acetate, as compared to using the 50:50 mixture alone or using the TEGO Sorb material alone.
The following mixtures were prepared and molded into stick articles as set forth above:
The “V” value of the resulting coating for Example IIIA is 8.65. The “V” value of the resulting coating for Example IIIB is 8.35.
The same examples are carried out (a) in the absence of the TEGO Sorb but in the presence of the 30:30:40 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate and (b) in the absence of any known malodor blocking compounds but in the presence of the TEGO Sorb. In each example that is carried out in the absence of TEGO Sorb and in the presence of the 30:30:40 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate the “V” values are 3.6 for Example IIIA without the TEGO Sorb and 3.8 for example IIIB without the TEGO Sorb. In each example that is carried out in the absence of any known malodor blocking compound but in the presence of TEGO Sorb, the “V” values are 4.65 without any known malodor blocking compound for Example IIIA and 4.55 without any known malodor blocking compound for Example IIIB. This example demonstrates the superiority and synergism of the combination of TEGO Sorb when used with a 50:50 mixture of 1-cyclohexylethan-1-yl butyrate and 1-cyclohexylethan-1-yl acetate, as opposed to using a 50:50 mixture of 1-cyclohexylethan-1-yl butyrate and 1-cyclohexylethan-1-yl acetate alone, or using TEGO Sorb, alone.
The following mixtures were prepared and molded into stick articles as set forth above:
The “V” value of the resulting coating for Example IVA is 8.75. The “V” value of the resulting coating for Example IVB is 8.90. The “V” value of the resulting coating for Example IVC is 9.10.
The same examples are carried out (a) in the absence of the TEGO Sorb but in the presence of the 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate and (b) in the absence of any malodour blocking compounds but in the presence of the TEGO Sorb. In each example that is carried out in the absence of TEGO Sorb and the presence of the 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate the “V” values are 3.9 for Example IVA without the TEGO Sorb, 3.8 for Example IVB without the TEGO Sorb and 3.65 for Example IVC without the TEGO Sorb. In each example that is carried out in the absence of any malodor blocking compound but in the presence of TEGO Sorb, the “V” values are 4.95 without any malodor blocking compound for Example IVA, 4.85 without any malodor blocking compound for Example IVB and 4.70 without any malodor blocking compound for Example IVC. This example demonstrates the superiority and synergism of the combination of TEGO Sorb when used with a 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan- 1-yl propionate and 2′-hydroxy- 1′-ethyl(2-phenoxy)acetate, as opposed to using a 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan- 1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate alone, or using TEGO Sorb, alone. This example also demonstrates that when using the combination of TEGO Sorb with a 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate, a lower concentration of the combination in a molded stick article, such as about 4.75% was found to be more effective than a higher concentration of the combination, such as about 13%.
Two 1 foot square damp cotton cloth swatches (Identified as Swatch A and Swatch B) and two 1 foot square dry cotton cloth swatches (Identified as Swatch C and Swatch D) were each exposed to cigar smoke evolved from 4 King Edward VII fresh cigars in four separate 3 ft3 air-tight enclosed chambers for a period of 12 hours thereby imparting an intense tobacco malodor to each swatch. The four swatches were then removed from the chambers and each swatch was separately washed for a wash time of 6 minutes and a rinse time of 2 minutes as follows:
(a) Swatch A and Swatch C
A liquid detergent composition was prepared as described in Example 4 on Page 6 of U.S. patent application US 2003/0114323 A1 published on Jun. 19, 2003, containing 99.775% detergent base (HLB Value of 13.2) and 0.225% of the following mixture:
(b) Swatch B and Swatch D
A liquid detergent composition as described in Example 4 on Page 6 of U.S. patent application US 2003/0114323 A1 published on Jun. 19, 2003, containing 100% detergent base (HLB Value of 13.2).
Each of the swatches were then measured by a 10 member expert panel for tobacco malodor intensity, scaled on a scale of 0-9, and the results are summarized in
Based upon the scoring criteria set forth above, a lower score is desirable for the malodor intensity and a higher score is more desirable for panelist preference. The test results reported above are consistent in their result. With the combination of TEGO Sorb and malodor blocking compounds, Swatches A and C, the resulting malodor intensity is low and the panelist preference is high. When the TEGO Sorb material is not provided, Swatches B and D, the resulting malodor intensity is high and the panelist preference is low.
