The following specification particularly describes the invention and the manner in which it is to be performed

UNIVERSAL SENSORY STRUCTURANT
FIELD OF THE INVENTION
The present invention is directed to universal sensory structurants and a method for making the same. More particularly the present invention is directed to sensory structurants comprising a polysaccharide carbohydrate comprising at least 75% by weight amylopectin wherein the carbohydrate has been treated and swollen with a solvent comprising hydroxylated polymer comprising less than 100 silane repeat units. The universal sensory modifiers of this invention can be used in formulating topical compositions which unexpectedly result in superior sensory benefits after application.
BACKGROUND OF THE INVENTION
Many consumers are concerned with the characteristics of their skin. For example consumers are concerned with the degree of pigmentation of their skin, freckles and/or age spots. Other consumers are concerned with skin imperfections that include wrinkles, large pores, acne and/or an oily appearance.
While it is desirable for consumers to hide or mask skin imperfections with topical compositions, such compositions tend to leave the consumer with poor sensory sensations. For example conventional skin lightening compositions formulated with silicone elastomers can be tacky and oily, thereby yielding an unpleasant feel during the skin lightening process.
There is an increasing interest to develop topical compositions that deliver a benefit to the consumer yet do not result in undesirable sensory sensations upon application. This invention, therefore, is directed to universal sensory structurants comprising a polysaccharide carbohydrate comprising at least 75% by weight amylopectin wherein the carbohydrate has been treated and swollen with a solvent comprising hydroxylated polymer comprising less than 100 silane repeat units. The universal sensory structurants of this invention can be used in formulating topical compositions which unexpectedly result in superior sensory benefits after application.

Efforts have been disclosed for making topical compositions that provide skin benefits. In US 2007/0237730 A1, cosmetic compositions with soft focus properties are described.
Other efforts have been disclosed for making topical compositions that provide skin benefits. In US 7 247 294 and US 7 250 158, skin lightening agents and compositions are described.
Still other efforts have been disclosed for making topical compositions that provide skin benefits. In US 7 192 598, wet-skin treatment compositions are described,
None of the additional information above describes a universal sensory structurant comprising a polysaccharide carbohydrate comprising at (east 75% by weight amylopectin wherein the carbohydrate has been treated and swollen with a solvent comprising less than 100 silane repeat units. Moreover, none of the additional information above describes a topical composition comprising a universal sensory structurant as described herein.

It should be known that commercially acceptable and conventional vehicles may be used, acting as diluents, dispersants and/or carriers for the topical composition described herein. Therefore the cosmetically acceptable vehicle suitable for use in this invention may be aqueous-based, anhydrous or an emulsion whereby a water-in-oil or oil-in-water emulsion is generally preferred. If the use of water is desired, water typically makes up the balance of the topical composition, and preferably makes up from about 5 to about 99%, and most preferably from over 50 to about 90% by weight of the topical composition, including all ranges subsumed therein.
In addition to water, organic solvents may be optionally included to act as carriers or to assist carriers within the compositions of the present invention. Illustrative and non-limiting examples of the types of organic solvents suitable for use in the present invention include alkanols like ethyl and isopropyl alcohol, mixtures thereof or the like.
Other optional additives suitable for use include ester oils like isopropyl myristate, cetyl myristate, 2-octyldodecyl myristate, avocado oil, almond oil, olive oil, neopentylglycol dicaprate, mixtures thereof or the like. Typically such ester oils assist in emulsifying the topical composition of this invention, and an effective amount is often used to yield a stable, and most preferably water-in-oil emulsion.
Emollients may also be used, if desired, as carriers within the topical composition of the present invention. Alcohols like 1-hexadecanol (i.e. cetyl alcohol) are often desired as are the emollients generally classified as silicone oils and synthetic esters.

In an often preferred embodiment, taurate copolymers are used in the topical compositions of this invention.
Collectively, the water, solvents, silicones, esters, fatty acids, humectants and/or thickeners will constitute the cosmetically acceptable carrier in amounts from 1 to 99.9%, preferably from 80 to 99% by weight.
Surfactants may also be present in topical composition of the present invention. Total concentration of the surfactant will range from about 0 to about 40%, and preferably from about 0 to about 20%, optimally from about 0 to about 5% by weight of the composition. The surfactant may be selected from the group consisting of anionic, nonionic, cationic and amphoteric actives.

Preferably the amount of fragrance employed in the topical composition of this invention is in the range from about 0.0% to about 10%, more preferably about 0.00001% to about 5 wt %, most preferably about 0.0001% to about 2%.
Various types of active ingredients may be used in the topical compositions of the present invention. Actives are defined as skin benefit agents other than emollients and other than ingredients that merely improve the physical characteristics of the composition. Although not limited to this category, general examples include talcs and silicas, as well as alpha-hydroxy acids, beta-hydroxy acids, peroxides, zinc salts and sunscreens.
Beta-hydroxy acids include salicylic acid, for example. Zinc pyrithione is an example of the zinc salts useful in the topical composition of the present invention.
Sunscreens include those materials commonly employed to block ultraviolet light. Illustrative compounds are the derivatives of PABA, cinnamate and salicylate. For

example, avobenzophenone (Parsol 1789®), octyl methoxycinnamate and 2-hydroxy-4-methoxy benzophenone (also known as oxybenzone) can be used. Octyl methoxycinnamate and 2-hydroxy-4-methoxy benzophenone are commercially available under the trademarks, Parsol MCX and Benzophenone-3, respectively. The exact amount of sunscreen employed in the compositions can vary depending upon the degree of protection desired from the sun's UV radiation. Additives that reflect or scatter the suns rays may also be employed. These additives include oxides like zinc oxide and titanium dioxide.
Many topical compositions, especially those containing water, should be protected against the growth of potentially harmful microorganisms. Anti-microbial compounds, such as triclosan, and preservatives are, therefore, typically necessary. Suitable preservatives include alkyl esters of p-hydroxybenzoic acid, hydantoin derivatives, propionate salts, and a variety of quaternary ammonium compounds. Particularly preferred preservatives of this invention are methyl paraben, propyl paraben, phenoxyethanol and benzyl alcohol. Preservatives will usually be employed in amounts ranging from about 0.1% to 2% by weight of the composition.

When desired, these ingredients typically make up from about 0.01 to about 10 percent by weight of the topical composition.
When making topical composition of the present invention, the desired ingredients, including the universal sensory structurant, are mixed, in no particular order, and usually at temperatures from about ambient to about 80°C and under atmospheric pressure.

The packaging for the composition of this invention can be a patch, bottle, tube, roll-ball applicator, propellant driven aerosol device, squeeze container or lidded jar..
The examples which follow are provided to illustrate and facilitate an understanding of the invention. The examples are not intended to limit the scope of the claims.
Example 1
One part by weight solvent comprising a hydroxylated polymer with silane units was combined with one part by weight a polysaccharide carbohydrate comprising at least 75% by weight amylopectin. The resulting mixture was heated to about 70°C for about three hours. The polysaccharide carbohydrate used contained about 10 percent by weight water.

Dow Corning ST-dimethiconol 40 Corn Starch 25% Dihydroxylated, 200 silane units
Dow Corning 5T-dimethiconol 40 Tapioca 70% Dihydroxylated, 200 silane units
Dow Corning ST-dimethiconol 40 Waxy corn starch 80% Dihydroxylated, 200 silane units
Shin Etsu RF700 Corn starch 50% Dihydroxylated, 100 silane units
Shin Etsu RF700 Tapioca 100% Dihydroxylated, 100 silane units
Shin Etsu RF700 Waxy corn starch 120% Dihydroxylated, 100 silane units
Shin Etsu KF9701 Corn starch 70% Dihydroxylated, 45 silane units
Shin Etsu KF 9701 Tapioca 115% Dihydroxylated, 45 silane units
Shin Etsu KF 9701 Waxy corn starch 150% Dihydroxylated, 45 silane units
Shin Etsu X-21-5841 Corn starch 80% Dihydroxylated, 15 silane units

Shin Etsu X-21-5841 Waxy corn starch 170% Dihydroxylated, 15 silane units
The results indicate that polysaccharide carbohydrate consistent with this invention in combination with solvent consistent with this invention yields excellent polysaccharide carbohydrate swelling (A size = the percent increase in size of the polysaccharide

carbohydrate) and no gellation when mixed with water. Corn starch contained about 71% by weight amylopectin, waxy corn starch contained about 100% by weight amylopectin and tapioca was about 83% by weight amylopectin.
Examples 2-29
Commercially available moisturizers, such as Dove® Proage® Beauty Body Lotion were modified and assessed as described below. Waxy corn starch and tapioca deplete of alkyl and/or alkenyl functionalization did swell as well as functionalized polysaccharide carbohydrate. Skilled panelists assessed all modified compositions. Universal sensory structurants were prepared by heating at 70°C for three hours, 50% by weight polysaccharide carbohydrate and 50% by weight solvent (dimethiconol).
A. Compositions made in examples 2 and 3 were prepared with 1 and 2% by weight
tapioca, respectively. As tapioca increased, negative sensory (draggy, non-silky)
attributes were realized in the commercially available moisturizers.
B. Compositions made in examples 4 and 5 were prepared with 1 and 2% by weight
universal sensory structurant, respectively, made according to this invention (50%
by weight tapioca, 50% by weight solvent). As universal sensory structurant
increased, the composition became more silky with excellent sensory benefits.
C. Compositions made in examples 6 and 7 were prepared in a manner similar to
the one used to make the compositions of example 4 and 5 except that C12 alkyl
functionalized (2%) tapioca was used. Assessment revealed exceptional sensory
performance, increasing with the addition of universal sensory structurant.
D. Compositions made in examples 8 and 9 were prepared in a manner similar to
the one described in examples 2 and 3 except that 1% by weight of taurate
copolymer (e.g. Simulgel) was also used. Sensory benefits were not realized.
E. Compositions made in examples 10 and 11 were prepared in a manner similar to
the one described in examples 4 and 5 except that 1% by weight of taurate
copolymer (e.g. Simulgel) was also added. Sensory benefits of the compositions

were even better than the benefits realized for the compositions of examples 4 and 5.
F. Compositions made in examples 12 and 13 were prepared in a manner similar to
the one described in examples 6 and 7 except that C12 alkyl functionalized (2%)
tapioca was used. Assessment revealed exceptional sensory performance,
increasing with the addition of universal sensory structurant.
G. Compositions made in examples 14 and 15 were prepared with 1% potato starch
(80-120 microns in diameter). Processing in solvent was performed similar to the
manner described in examples 4 and 5. All compositions made were draggy and
had poor sensory attributes even upon the addition of taurate copolymer.
H. Compositions made in examples 16-29 were made via methods similar to the ones described in examples 2-15 except that waxy corn starch (100% amylopectin) was used in lieu of tapioca. The results show the same trends except that waxy corn starch was even better than tapioca since it had better swelling characteristics in solvent.
The results indicate that universal sensory structurants prepared according to this invention yield compositions with very desirable sensory benefits and especially, when a functionalized polysaccharide carbohydrate is used with a taurate copolymer. No gellation was observed when compositions were made consistent with this invention.
Example 30
Compositions in this example were prepared using universal sensory structurant prepared with tapioca starch in a manner similar to the one described in examples 6 and 7 and 12 and 13, except that plasticizer (e.g. propyl benzoate) at 10 to 30% by weight was added to the solvent (based on total weight of solvent). The results indicated that compositions with plasticizer were softer and more elastic than compositions without the plasticizer.
