Abstract

A thickened aqueous composition containing from about 0.01% to about 10%, by weight, of an superabsorbent polymer, from about 0.1% to about 20%, of a silicone elastomer; and from about 20% to about 98% of water.

First claim

What is claimed is:

1. A thickened aqueous composition comprising:
a. from about 0.01% to about 10%, by weight, of a superabsorbent polymer in the form of sodium polyacrylate starch particles having a non-swollen, number-average particle size of between 2 and 100 microns;
b. from about 0.1% to about 20%, by weight, of a silicone elastomer; and
c. from about 20% to about 98% of water, wherein the superabsorbent polymer is present in the water.

2. The thickened aqueous composition of claim 1 wherein the aqueous composition is mixed with an oil phase to form an oil- in-water or water-in-oil-in-water emulsion.

3. The thickened aqueous composition of claim 2 , wherein the aqueous composition further comprises from about 0.01 to about 10%, by weight, of an emulsifier.

4. The thickened aqueous composition of claim 3 , wherein the emulsifier is selected from a group consisting of ethers of glycerol, polyglycerol, sucrose, glucose, or sorbitol; esters of glycerol, polyglycerol, sucrose, glucose, or sorbitol; and mixtures thereof.

5. The thickened aqueous composition of claim 1 further comprising from about 1% to about 40%, by weight, of a UV active selected from a group consisting of avobenzone, cinoxate, dioxybenzone, homosalate, menthyl anthranilate, octyl salicylate, oxybenzone, padimate O, phenylbenzimidazole sulfonic acid, sulisobenzone, trolamine salicylate, titanium dioxide, zinc oxide, diethanolamine methoxycinnamate, digalloy trioleate, ethyl dihydroxypropyl PABA, glyceryl aminobenzoate, lawsone with dihydroxyacetone, red petrolatum, ethylhexyl triazone, dioctyl butamido triazone, benzylidene malonate polysiloxane, terephthalylidene dicamphor sulfonic acid, disodium phenyl dibenzimidazole tetrasulfonate, diethylamino hydroxybenzoyl hexyl benzoate, bis diethylamino hydroxybenzoyl benzoate, bis benzoxazoylphenyl ethylhexylimino triazine, drometrizole trisiloxane, methylene bis30 benzotriazolyl tetramethylbutylphenol, and bis-ethylhexyloxyphenol methoxyphenyltriazine, 4-methylbenzylidenecamphor, isopentyl 4-methoxycinnamate and combinations thereof.

6. The thickened aqueous composition of claim 5 , wherein the UV active is selected from a group consisting of avobenzone, homosalate, octyl salicylate, oxybenzone, phenylbenzimidazole sulfonic acid, titanium dioxide, zinc oxide, ethylhexyl triazone, dioctyl butamido triazone, benzylidene malonate polysiloxane, terephthalylidene 5 dicamphor sulfonic acid, disodium phenyl dibenzimidazole tetrasulfonate, diethylamino hydroxybenzoyl hexyl benzoate, bis diethylamino hydroxybenzoyl benzoate, bis benzoxazoylphenyl ethylhexylimino triazine, drometrizole trisiloxane, methylene bis-benzotriazolyl tetramethylbutylphenol, and bis-ethylhexyloxyphenol methoxyphenyltriazine, isopentyl 4- methoxycinnamate and combinations thereof.

7. The thickened aqueous composition of claim 2 , further comprising a solvent is selected from a group consisting of di-isopropyl adipate, butyl phthalimide, isopropyl phthalimide, phenylethyl benzoate, dicaprylyl carbonate, isopropyl lauroylsarcosinate, isononyl isononanoate, butyl octylsalicylate, dioctyl malate, dicaprylyl maleate, isopropyl isostearate, propylene glycol dicaprate, esters of C12-C15 alcohol benzoates, isosorbide diesters, and derivatives and mixtures thereof.
