Alkoxysilane derivatives of N-acyl amino acids, N-acyl dipeptides, and N-acyl tripeptides, and particles and stable oil-in-water formulations using the same

摘要

Hydrophilic N-acylamino acid, N-acyl dipeptide, and N-acyl tripeptide substituted silanes are prepared which can be utilized as reactive surface treatments for particles of pigments, minerals, and fillers. These treated particles form stable dispersions in the aqueous phase of oil-in-water mixtures that are suitable for cosmetic applications. The treated particles may also be used in pressed powder and color cosmetic formulations.
