BACKGROUND

[0001] Most individuals buy and use a hair shampoo for its cleansing properties, however, present-day hair shampoos generally are formulated with highly-effective synthetic surfactants that exhibit a high foam and primarily clean, as opposed to conditioning the hair. Therefore, many shampoos neither help detangle wet hair nor impart any residual hair conditioning benefits to dry hair, such as the manageability or styleability of hair sets, Consequently, after shampooing, the hair normally is left in a cosmetically-unsatisfactory state because an anionic surfactant-based hair shampoo composition not only removes all of the dirt and soil from the hair, but also removes essentially all of the sebum that is naturally present on the surface of the hair fibers. While conditioner compositions have been formulated to combat the challenges raised when shampooing, these conditioner compositions do not balance all of the desired characteristic with respect to combing, softness, bulk, and fly away. Therefore, the need exists for a new personal care product that can provide the desired conditioning performance to hair.

[0043] The non-fibrous body 120 may further comprise one or more active agents such as a starch or a starch derivative. The starch may be a natural starch.

[0044] Naturally occurring starch is generally a mixture of linear amylose and branched amylopectin polymer of D-glucose units. The amylose is a substantially linear polymer of D- glucose units joined by (l,4)-α-D links. The amylopectin is a highly branched polymer of D- glucose units joined by (l,4)-α-D links and (l,6)-α-D links at the branch points. Naturally occurring starch typically contains relatively high levels of amylopectin, for example, com starch (64-80% amylopectin), waxy maize (93-100% amylopectin), rice (83-84% amylopectin), potato (about 78% amylopectin), and wheat (73-83% amylopectin). Though all starches are potentially useful herein, the present invention is most commonly practiced with high amylopectin natural starches derived from agricultural sources, which offer the advantages of being abundant in supply, easily replenishable and inexpensive.

[0045] As used herein, “starch" includes any naturally occurring unmodified starches, modified starches, synthetic starches and mixtures thereof, as well as mixtures of the amylose or amylopectin fractions; the starch may be modified by physical, chemical, or biological processes, or combinations thereof. The choice of unmodified or modified starch for the present invention may depend on the end product desired. In one embodiment of the present invention, the starch or starch mixture useful in the present invention has an amylopectin content from about 20% to about 100%, more typically from about 40% to about 90%, even more typically from about 60% to about 85% by weight of the starch or mixtures thereof.

[0046] Suitable naturally occurring starches can include, but are not limited to, com starch, potato starch, sweet potato starch, wheat starch, sago palm starch, tapioca starch, rice starch, soybean starch, arrow root starch, ami oca starch, bracken starch, lotus starch, waxy maize starch, and high amylose com starch. In a preferred embodiment, the starch is com starch.

[0047] The starch may be present in an amount ranging from about 5.0 wt % to about 15.0 wt. % - based on the total weight of the non-fibrous body 120 - including all percentages and subranges there-between. In some embodiments, the starch may be present in an amount ranging from about 7.0 wt. % to about 13.0 wt % - based on the total weight of the non-fibrous body 120 - including all percentages and sub-ranges there-between. In some embodiments, the starch may be present in an amount ranging from about 9.0 wt. % to about 11.0 wt. % - based on the total weight of the non-fibrous body 120 - including all percentages and sub-ranges therebetween.

[0048] The non-fibrous body 120 may further comprise one or more fragrances or perfume. The fragrance and/or perfume may be present in an amount ranging from about 25.0 wt. % to about 50.0 wt. % - based on the total weight of the non-fibrous body 120 - including all percentages and sub-ranges there-between. In some embodiments, the fragrance and/or perfume may be present in an amount ranging from about 30.0 wt. % to about 45.0 wt. % - based on the total weight of the non-fibrous body 120 - including all percentages and sub-ranges there-between. In some embodiments, the fragrance and/or perfume may be present in an amount ranging from about 35.0 wt. % to about 40.0 wt. % - based on the total weight of the non-fibrous body 120 - including all percentages and sub-ranges there-between.

[0049] Non-limiting examples of fragrances and perfumes include odor compounds selected from. 7-acetyl-l,2,3,4,5,6,7,8-octahydro-l,l,6,7-tetramethylnaphth alene, α-ionone, β-ionone, γ- ionone α-isomethylionone, methylcedrylone, methyl dihydrojasmonate, methyl 1,6,10-trimethyl- 2,5,9-cyclododecatrien-l-yl ketone, 7-acetyl-l,l,3,4,4,6-hexamethyltetralin, 4-acetyl -6-tert- butyl-l.l-dimethylindane, hydroxyphenylbutanone, benzophenone, methyl β-naphthyl ketone, 6- acetyl-l,l,2,3,3,5-hexamethylindane, 5-acetyl-3-isopropyl-l,l,2,6-tetramethylindane, 1 dodecanal, 4-(4-hydroxy-4-methylpemyl)-3-cyclohexene-l-carboxaldehyde, 7-hydroxy-3,7- dimethyloctanal, 10-undecen-l-al, isohexenylcyclohexylcarboxaldehyde, formyltricyclodecane, condensation products of hydroxycitronellal and methyl anthranilate, condensation products of hydroxycitronellal and indole, condensation products of phenylacetaldehyde and indole, 2- methyl-3 -(para-tert-butyl phenyl )propional dehy de, ethylvanillin, heliotropin, hexylcinnamaldehyde, amylcinnamaldehyde, 2-methyl-2-(isopropylphenyl)propionaldehyde, coumarin, γ-decalactone, cyclopentadecanolide, 16-hydroxy-9-hexadecenoic acid lactone, l,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta-Y-2-b enzopyran, β-naphthol methyl ether, ambroxane, dodecahydro-3a,6,6,9a-tetramethylnaphtho[2, 16]furan, cedrol, 5-(2,2,3- trimethy I cyclopent-3 -enyl)-3 -methy lpentan-2-ol , 2-ethyl-4-(2,2,3-trimethyl-3-cyclopenten-l-yl)- 2-buten-l-ol, caiyophyllene alcohol, tricyclodecenyl propionate, tricyclodecenyl acetate, benzyl salicylate, cediyl acetate, and tert-butylcyclohexyl acetate.

[0050] Other fragrances may include odor compounds selected from essential oils, resinoids and resins from a large number of sources, such as, for example, Peru balsam, olibanum resinoid, styrax, labdanum resin, nutmeg, cassia oil, benzoin resin, coriander, and lavandin. Further suitable fragrances include odor compounds selected from phenylethyl alcohol, terpineol, linalool, linalyl acetate, geraniol, nerol, 2-(l,l-dimethylethyl)cyclo-hexanol acetate, benzyl acetate, and eugenol.

[0051] The fragrances or perfumes can be used as single substances or in a mixture with one another.

[0052] In some embodiments, the fragrance may be provided as a microcapsule formulation, whereby the odor-compound is surrounded by a 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.

[0053] 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.

[0054] Stable shell materials include polyaciylate-based materials obtained as reaction product of an oil soluble or dispersible amine with a multifunctional acrylate or methacrylate monomer or oligomer, an oil soluble acid and an initiator, in presence of an anionic emulsifier comprising a water soluble or water dispersible acrylic acid alkyl acid copolymer, an alkali or alkali salt. Gelatin-based microcapsules may be prepared so that they dissolve quickly or slowly in water, depending for example on the degree of cross-linking.

[0055] 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. [0056] The odor compound may be included as part of a microencapsulated fragrance or perfume or a non-encapsulated fragrance or perfume.

[0057] The film 100 of the present invention may be formed by mixing together the binder (e.g., polymeric binder), the surfactant, and the fragrance to form a blend. In some embodiments, the film 100 of the present invention may be formed by mixing together the binder (.e.g, polymeric binder), the surfactant, the plasticizer, the starch, and the fragrance to form a blend. The blend may be a liquid. The blend may then be processing into a sheet, which is then cut into multiples of the non-fibrous body 120, whereby each non-fibrous body 120 forms the film 100.

[0058] Referring now to FIG. 3, the present invention further includes a personal care composition 200 that comprises the film 100 of the present invention. The present invention further comprises a personal care product 1 comprising the personal care composition of the present invention.

[0059] The personal care composition 200 may be a hair-conditioning composition, a hair shampoo composition, and the like. The personal care composition 200 of the present invention may further comprise an additional components suitable for use with a hair-conditioning and/or hair-shampoo composition.

[0060] The personal care product 1 of the present invention may include a container 10 comprising a reservoir 11 where the personal care composition 200 may be located. The container 10 may further comprise an opening through which the personal care composition 200 may be dispensed out of from the reservoir 11.

[0061] The personal care product 1 may further comprise a cap 5 which may seal the opening of the container to seal the reservoir 11, thereby preventing any personal care product 200 from inadvertently escaping the reservoir 11.

[0062] While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope of the present invention. Thus, the spirit and scope of the invention should be construed broadly as set forth in the appended claims. EXAMPLES

[0063] An experiment was performed to test the conditioning performance of the film of the present invention. Two film formulations were prepared - as set forth below in Table 1.

Table 1

[0064] Each example was then tested for wet combing, dry combing, and softness. Two (2) sets of five (5) hair tresses each are prepared and cleaned with 20% solution of sodium laureth sulfate. Each set of hair tresses is washed with 1 mL of a commercially available shampoo, and 0.1 g of either an exemplary composition of the present invention or a comparative composition, per hair tress. After each treatment, trained in-house expert panelists, blindly evaluate the tresses. Tresses are randomly assigned to avoid bias. Panelist evaluate both wet and dry stages. Wet stage evaluation is more relevant for describing hair conditioning benefit. This relates to ease of combing. The best performer are assigned a score of two points and the low performer assigned a score of one point.

[0065] Hair volume and alignment evaluations are carried out with Rumba equipment from Bossa Nova-Tech. Two (2) sets of six (6) hair tresses are prepared and cleaned with twenty percent (20%) solution of sodium laureth sulfate. Each set is then treated with 0.5 mL of a commercially available shampoo and 0.1 g of either an exemplary composition of the present invention or a comparative composition, per hair tress. The Rumba equipment takes pictures of a hair tress suspended using a clamp while illuminating the sample with polarized light in multiple orientations. The pictures are processed with Rumba software to determine hair orientation using a color index. The comparison of colored pixels on each image with the non-reflective background surface is used to measure the volume of the hair tress. The software is also used to measure hair volume and alignment. The results of these experiments are described below in Table 2.

Table 2

[0066] As demonstrated by the data described in Table 2 (above), exemplary films of the present invention provide an unexpected improvement in wet combing, as well as enhancement of softness, volume, and hair alignment without any detrimental impact on dry combing performance.

[0067] As those skilled in the art will appreciate, numerous changes and modifications may be made to the embodiments described herein, without departing from the spirit of the invention. It is intended that all such variations fall within the scope of the invention.
