| 20120076840 | 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 - 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. | 03-29-2012 |
| 20120071678 | TRIHYDRIDOSILYL-TERMINATED POLYSILANES AND METHODS OF PREPARATION - Novel trihydridosilyl-terminated polysilanes and methods for their synthesis, which are applicable to other polysilanes, are provided. The synthetic methods provide for facile preparation of products with minimal handling of pyrophoric intermediates and byproducts. The novel compounds contain at least three silicon-silicon bonds and at least one terminal silicon atom having three hydrogen substituents. | 03-22-2012 |
