Topical cosmetic compositions containing a 4-substituted resorcinol derivative along with N-acetyl methionine exhibit improved storage stability and oxidative stability. A method of stabilizing 4-ethyl resorcinol or 4-hexyl resorcinol in a composition comprising a cosmetically acceptable vehicle by adding to the composition Acetyl Methionine in an amount sufficient to stabilize said 4-ethyl resorcinol or 4-hexyl resorcinol. Use of the N-Acetyl Methionine and stabilized 4-substituted resorcinol derivatives in the manufacture of a topical cosmetic composition.

This application provides, among other things, novel aqueous monophasic compositions useful for combining and delivering poorly compatible ingredients, for example to deliver effective levels of cationic antibacterial agents in combination with anionic polymers, e.g. that protect against erosion and staining, by addition of a stabilizing amount of a polyamine, e.g. lysine, and methods for making and using the same.

The present disclosure relates to silica particles comprising repeating units of (SiO.sub.4/2) that are spherical in shape, which has the benefit of compatibility with personal care components and the resulting personal care applications. The present disclosure also relates to methods of preparing silica particles.

Heterocyclic compounds are provided. In particular, the heteroatom of the heterocyclic compound may be nitrogen. The heterocyclic compounds may demonstrate capacity of stabilizing photoactive compounds. Topical compositions comprising these heterocyclic compounds are also provided. In particular, these topical compositions further comprise photoactive compounds. Methods for stabilizing photoactive compounds are also provided. These methods comprise mixing the photoactive compounds with photostabilizing heterocyclic compounds.

The present invention relates to the use of a methacrylate or acrylate modified polysaccharide; or a single-chain polysaccharide methacrylate or acrylate-based nanoparticle, having a surface tension measured by Du Noüy Ring method equal to or lower than 63 mN/m, as oil-in-water emulsion stabilizer; and an oil-in-water emulsion stabilizer composition, and an oil-in-water emulsion containing them. It also relates to processes for their preparation, and their uses.

Disclosed is a self-invertible inverse latex having an aqueous phase, including: a) a cross-linked anionic polyelectrolyte (P) including:—at least one first monomer unit derived from 2-methyl-2-[(1-oxo-2-propenyl)amino] 1-propane sulfonic acid in the form of a free or partially or totally salified acid; and—at least one second monomer unit derived from at least one monomer selected from the elements of the group consisting of (2-hydroxyethyl)acrylate, (2,3-dihydroxypropyl)acrylate, (2-hydroxyethyl)methacrylate, (2,3-dihydroxypropyl)methacrylate, or vinylpyrrolidone; and—at least one monomer unit derived from a cross-linking polyethylenic monomer (AR); b) at least one chelating compound (SQ) selected from the elements of the group consisting of ethylenediamine disuccinic acid in the form of trisodium salt, tetrasodium salt of glutamic acid, N,N diacetic, or the sodium salt of imminosuccinic acid.

A method for making a composition for enamel regeneration proposes to encapsulate soluble calcium and phosphate salts within corresponding internal water phases in respective water-in-oil-in-water emulsions stabilized by solid particles, and add them to a toothpaste, enamel restoring gel or mouth wash base. In this way, the soluble calcium and phosphate salts can be present stably in the toothpaste, enamel restoring gel or mouth wash over a long period of time. When the toothpaste, enamel restoring gel or mouth wash of the present disclosure is used in oral cavity, the water-in-oil-in-water emulsions rapture under the effect of friction and pressing, releasing the soluble calcium and phosphate salts encapsulated within the corresponding internal water phases. As a result, the liquid in the user's oral cavity will contain high concentrations of calcium and phosphate ions, which can enhance the rate of enamel remineralization.
