Patent Grant
9340757
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/or 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 products and/or any situs that is contacted with such products. Consumer products such as hard surface cleaners, for example, limescale removers often use acids to aid the removal of deposits such as lime scale. Such acids have a harsh odour which results in a negative consumer response to the product and is challenging to overcome. Typically ingredients with a similarly strong intensity are employed to counter the original harsh odour. Unfortunately, such ingredients merely compete with and do not effectively neutralize the original harsh odour. As a result, the original harsh odour is still clearly noticeable.
Applicants recognized that the reason such harsh odour is so challenging to overcome is that such acids impact the trigeminal nerve. The trigeminal nerve (the fifth cranial nerve, also called the fifth nerve, or simply CNV or CN5) is a nerve responsible for sensation in the face and certain motor functions such as biting and chewing. It is the largest of the cranial nerves. Applicants recognized that the impact of harsh odours on the trigeminal nerve can be reduced with the use of specific perfume ingredients. Surprisingly, Applicants found that certain perfume materials and combinations thereof, which are independent of odour intensity, are capable of neutralizing the aforementioned harsh odours.
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/or using such perfume raw materials, perfume delivery systems and consumer products.

Perfume Delivery Systems
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. Such perfume delivery systems include:
Reservoir Systems:
Reservoir systems are also known as a core-shell type technology, or one in which the fragrance is surrounded by a perfume release controlling membrane, which may serve as a protective shell. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane. Microparticles or pressure sensitive capsules or microcapsules are examples of this technology. Microcapsules of the current invention are formed by a variety of procedures that include, but are not limited to, coating, extrusion, spray-drying, interfacial, in-situ and matrix polymerization.
The possible shell materials vary widely in their stability toward water. Among the most stable are polyoxymethyleneurea (PMU)-based materials, which may hold certain PRMs for even long periods of time in aqueous solution (or product). Such systems include but are not limited to urea-formaldehyde and/or melamine-formaldehyde. Gelatin-based microcapsules may be prepared so that they dissolve quickly or slowly in water, depending for example on the degree of cross-linking. Many other capsule wall materials are available and vary in the degree of perfume diffusion stability observed. Without wishing to be bound by theory, the rate of release of perfume from a capsule, for example, once deposited on a surface is typically in reverse order of in-product perfume diffusion stability. As such, urea-formaldehyde and melamine-formaldehyde microcapsules for example, typically require a release mechanism other than, or in addition to, diffusion for release, such as mechanical force (e.g., friction, pressure, shear stress) that serves to break the capsule and increase the rate of perfume (fragrance) release. Other triggers include melting, dissolution, hydrolysis or other chemical reaction, electromagnetic radiation, and the like. Suitable capsule wall materials include, in addition to aminoplasts, polyvinyl alcohol, polyvinyl pyrrolidone, polyethylene glycol, polysaccharides and modified polysaccharides, gel forming proteins, modified celluloses such as carboxymethylcelluloses and hydroxyethylcelluloses, polyacrylates, polyureas, polyurethanes and mixtures thereof. The capsules may be further coated with an additional coating that can improve the deposition and/or retention of the capsule on the desired surface. Suitable coating materials include a cationic polymer selected from the group consisting of selected from the group consisting of polysaccharides, cationically modified starch, cationically modified guar, polysiloxanes, poly diallyl dimethyl ammonium halides, copolymers of poly diallyl dimethyl ammonium chloride and vinyl pyrrolidone, acrylamides, imidazoles, imidazolinium halides, imidazolium halides, poly vinyl amine, copolymers of poly vinyl amine and N-vinyl formamide to the surface of the capsule to form a cationically coated polymer encapsulated material. Typical capsules have a diameter of 1 micron to 500 microns. The use of pre-loaded microcapsules requires the proper ratio of in-product stability and in-use and/or on-surface (on-situs) release, as well as proper selection of PRMs. Microcapsules that are based on urea-formaldehyde and/or melamine-formaldehyde are relatively stable, especially in near neutral aqueous-based solutions. These materials may require a friction trigger which may not be applicable to all product applications. Other microcapsule materials (e.g., gelatin) may be unstable in aqueous-based products and may even provide reduced benefit (versus free perfume control) when in-product aged.
Molecule-Assisted Delivery (MAD):
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 C Log P greater than about 2. Molecule-Assisted Delivery (MAD) may also include those described in U.S. Pat. No. 7,119,060.
Starch Encapsulated Accord (SEA):
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.
In one aspect, a material selected from the group consisting of Table 1 materials and mixtures thereof and/or a perfume selected from the group consisting of a Table 2 perfume and mixtures thereof are suitable for use, in perfume delivery systems at levels, based on total perfume delivery system weight, of from 0.001% to about 50%, from 0.005% to 30%, from 0.01% to about 10%, from 0.025% to about 5%, or even from 0.025% to about 1%.
In one aspect, the perfume delivery systems disclosed herein are suitable for use in consumer products, cleaning and treatment compositions and fabric and hard surface cleaning and/or treatment compositions, detergents, and highly compacted consumer products, including highly compacted fabric and hard surface cleaning and/or treatment compositions, for example highly compacted detergents that may be solids or fluids, at levels, based on total consumer product weight, from about 0.001% to about 20%, from about 0.01% to about 10%, from about 0.05% to about 5%, from about 0.1% to about 0.5%.
In one aspect, the amount of the material selected from the group consisting of Table 1 materials and mixtures thereof and/or a perfume selected from the group consisting of a Table 2 perfume and mixtures thereof, based on the Reservoir System weight, may be from about 0.1% to about 99%, from 25% to about 95%, from 30 to about 90%, from 45% to about 90%, from 65% to about 90%.
In one aspect, the amount of a material selected from the group consisting of Table 1 materials and mixtures thereof and/or a perfume selected from the group consisting of a Table 2 perfume and mixtures thereof based on total weight of starch encapsulates and starch agglomerates (Starch Encapsulated Accord (SEA)) ranges from 0.1% to about 99%, from 25% to about 95%, from 30 to about 90%, from 45% to about 90%, from 65% to about 90%. In one aspect, the perfumes disclosed in Table 1 and stereoisomers thereof are suitable for use, in such starch encapsulates and starch agglomerates. Such PRMs and stereoisomers thereof may be used in combination in such starch encapsulates and starch agglomerates.

In one aspect, a situs is optionally washed and/or rinsed, contacted with a particle according to the present invention or composition comprising said particle and then optionally washed and/or rinsed. For purposes of the present invention, washing includes but is not limited to, scrubbing, and mechanical agitation. The fabric may comprise most any fabric capable of being laundered or treated in normal consumer use conditions. Liquors that may comprise the disclosed compositions may have a pH of from about 3 to about 11.5. Such compositions are typically employed at concentrations of from about 500 ppm to about 15,000 ppm in solution. When the wash solvent is water, the water temperature typically ranges from about 5° C. to about 90° C. and, when the situs comprises a fabric, the water to fabric ratio is typically from about 1:1 to about 30:1.
In addition to the disclosure above, a method of neutralizing harsh odours, in particular harsh odours that impact the trigeminal nerve, for example harsh odours resulting from materials selected from the group consisting of phosphoric acid, salts thereof, and mixtures thereof; formic acid, salts thereof, and mixtures thereof; acetic acid, salts thereof, and mixtures thereof; citric acid, citrate, salts thereof, and mixtures thereof; lactic acid, salts thereof, and mixtures thereof; oxalic acid, salts thereof, and mixtures thereof; sulfuric acid, salts thereof, and mixtures thereof comprising:
The degree of acid coverage by a perfume, PRM or product comprising such materials, can be determined via human panel testing
For raw material testing 2-4 panelists are used so many PRMs can quickly be screened. The PRM is tested in combination with the acid containing product to determine how well is covers the acid odour. To create a dynamic yet consistent odour product is evaluated in a small cup with a closed lid the product is covered for a fixed time in all cases and the headspace purged and allowed to build for the same time interval before the next panelist can grade. In the consumer situation the product is being tested in effectively an open system. So to give this impression in the cup the headspace is only allowed to build for 2 minutes before removing the lid and evaluating. Gradings are spaced by 20 seconds to avoid the nose becoming saturated and grades are complete in sets of 6 PRMs. Grades between panelists are compared and if more than one grade apart are re-evaluated. Further samples are placed back into test blind to check reproducibility.
For final perfumes they are tested in a larger bathroom to give a more accurate consumer impression of the performance, we also test with a larger base of panelists typically 30 panelists are used.
Evaluations for both PRM and perfume testing are expressed on a 0-5 scale
0=absolutely no acid odour
1=very faint acid odour
2=noticeable character of acid odour but not uncomfortable
3=slight discomfort experienced whilst smelling
4=clear discomfort experienced whilst smelling
5=strong discomfort experienced whilst smelling perfume/PRM having no effect versus unperfumed product
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.
Table 2 Perfume1 is added at 25 and 50% to 3 existing perfumes and incorporated into acid containing surface care products. The resulting product is sprayed in a bathroom with controlled airflow temperature and humidity. In all cases the perfumes with the additional perfume from Example 1 resulted in a significantly lower acid odour as measured by a trained panel of 30 people. The experiment is repeated for each of Table 2 perfumes 2-5 and a similar benefit is obtained.
25 grams of butyl acrylate-acrylic acid copolymer emulsifier (Colloid C351, 25% solids, pka 4.5-4.7, (Kemira Chemicals, Inc. Kennesaw, Ga. U.S.A.) is dissolved and mixed in 200 grams deionized water. The pH of the solution is adjusted to pH of 4.0 with sodium hydroxide solution. 8 grams of partially methylated methylol melamine resin (Cymel 385, 80% solids, (Cytec Industries West Paterson, N.J., U.S.A.)) is added to the emulsifier solution. 200 grams of a material selected from the group consisting of Table 1 materials and mixtures thereof and/or a perfume selected from the group consisting of a Table 2 perfume and mixtures thereof, the balance of consumer product comprising an adjunct ingredient, and/or a perfume delivery system comprising a material selected from the group consisting of Table 1 materials and mixtures thereof and/or a perfume selected from the group consisting of a Table 2 perfume and mixtures thereof is added to the previous mixture under mechanical agitation and the temperature is raised to 50° C. After mixing at higher speed until a stable emulsion is obtained, the second solution and 4 grams of sodium sulfate salt are added to the emulsion. This second solution contains 10 grams of butyl acrylate-acrylic acid copolymer emulsifier (Colloid C351, 25% solids, pka 4.5-4.7, Kemira), 120 grams of distilled water, sodium hydroxide solution to adjust pH to 4.8, 25 grams of partially methylated methylol melamine resin (Cymel 385, 80% solids, Cytec). This mixture is heated to 70° C. and maintained overnight with continuous stirring to complete the encapsulation process. 23 grams of acetoacetamide (Sigma-Aldrich, Saint Louis, Mo., U.S.A.) is added to the suspension. An average capsule size of 30 um is obtained as analyzed by a Model 780 Accusizer.
