  • 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
    Publication number: 20160280737
    Abstract: 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.

  • Silanes with embedded hydrophilicity, dispersible particles derived therefrom and related methods
    Patent number: 9029586
    Abstract: The invention provides a silane compound that includes a hydrophobic group and a silane ester group linked by a hydrophilic group for use as a surface treatment to an inorganic material, such as a pigment, the silane including a hydrophobic group and a silane ester group linked by a hydrophilic group. The invention includes a coated particle including an inorganic material coated with the silane compound(s) and methods of improving the wettability and/or dispersibility of an inorganic material such as a pigment, wherein the method comprises depositing the silane compounds on the surface of a pigment.
