The present application relates to a polymer and a use thereof. The present application may provide a functional polymer which expresses a low solubility to a polar solvent and a non-polar solvent and which is suitable for forming a film. If applied to the use of cosmetics such as mascara or to medical uses, the polymer in the present application may express a tolerance to diverse solvents such as sebum, sweat, tears and the like, and thus enables makeup to last, etc. Accordingly, the polymer may be applied to diverse uses and used in film forming agents, cosmetic compositions, or cosmetics, or the like.

The present disclosure relates to a method for preventing spontaneous oxidation of an antioxidant, material thereof and uses thereof. More particularly, the present disclosure relates to a method for preventing oxidation of an antioxidant using aptamer specifically binding to its target antioxidant and aptamer-based control of the release rate of active ingredient in the hydrogel. Aptamer having such activity can have versatile applications such as cosmeceuticals and health beverages. As an example, we provide in the present disclosure the establishing method of aptamer targeting for Vitamin C and verification of its prevention of spontaneous oxidation of Vitamin C. We also provide the detailed method for trapping such aptamer-active ingredient complex in the hydrogel. It is expected that an aptamer-trapped hydrogel of the present disclosure has functions of controlling a release rate of the active ingredient through the aptamer-based sensing of specific substance released from the skin according to the skin conditions.

A composition and method is provided for synthesizing silicone particles with narrow size distributions and tunable degrees of crosslinking for encapsulation of an active ingredient or multiple active ingredients in the matrix of the particles for controlled release. The method comprises agitating at least one type of silane monomer having two, three or four siloxane bonds in an acidic aqueous solution under conditions sufficient to allow for hydrolysis of the monomers, adding a catalyst and a solution comprising a co-solvent and the active ingredient(s) to the acidic aqueous solution, and continuing to agitate the combined solution to allow for a condensation reaction and formation of silicone particles with a narrow size distribution encapsulating at least a portion of the active ingredient(s). The tunable degree of crosslink density of the particles formed is based on the ratios of the monomers used, which enables controlled release of the active ingredient(s) from the particles.

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.
