Disclosed is a process for preparing an encapsulated fragrance composition. The composition comprises a plurality of microcapsules dispersed in a dispersion medium. The microcapsules comprise a core and a shell around the core. The process comprises the consecutive steps of: a) Providing an aqueous phase (I) comprising at least one anionically modified polyisocyanate (A); b) Providing an organic phase (II) comprising at least one fragrance ingredient; c) Mixing the aqueous phase (I) and the an organic phase (II) to obtain a mixture; d) Forming an emulsion comprising droplets of the organic phase (II) in the continuous aqueous phase (I); e) Adding at least one polyfunctional amine; f) Effecting formation of shells around the droplets formed in step d), to obtain a dispersion of microcapsules. The process comprises the additional step of adding a polyisocyanate (B), which is different from polyisocyanate (A).

Compositions comprising a reaction product of a saccharide polymer and a fatty ester may be obtained in an aqueous phase in the presence of a hydroxide base and a neutral surfactant, the saccharide polymer comprising a dextran, a dextrin compound, or any combination thereof. The compositions also comprise one or more alcohols originating from the fatty ester upon forming the reaction product of the saccharide polymer and the fatty ester. The reaction product of the saccharide polymer and the fatty ester may be present in the aqueous phase at a concentration effective to lower a surface tension of the neutral surfactant. The fatty ester may comprise one or more glycerol esters, such as one or more plant and/or animal oils and/or fats, and the one or more alcohols originating from the fatty ester may comprise glycerol. Fatty acids originating from the fatty ester may be substantially straight-chain fatty acids.

This application provides, among other things, novel aqueous oral care compositions useful for combining and delivering poorly compatible ingredients, for example to deliver effective levels of cationic antibacterial agents in combination with anionic polymers 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 invention relates to a cosmetic composition containing the following Components (A) and (B): Component (A): a hydrophobic polymer which has a glass transition temperature Tg of 30° C. or higher, the polymer having a different kind of an electric charge to the following Component (B), or not having an electric charge; and Component (B): a hydrophilic ionic polymer. The cosmetic composition of the present invention can be suitably used in cosmetics for hair.

The present invention is directed to a naturally derived surfactant system and an end use composition comprising the surfactant system. The naturally derived surfactant system comprises an anionic and nonionic surfactant comprising polyglycerol ester that is stable in an end use composition having a pH from 4.8 to 6.5. Such end use compositions are mild, have excellent lathering characteristics, and do not require glycinates, polyglycosides, betaines, sultaines and sulfates.
