  • Patent number: 5756788
    Abstract: A process for making metal oxide hydrophobic by coating the metal oxide with a silicone polymer is disclosed. The hydrophobic metal oxide is prepared by contacting the metal oxide with a reactive silicone compound and then in a subsequent step the coated metal oxide is heated to 40.degree. to 100.degree. C. for between 1 and 10 hours. The resulting metal oxide is hydrophobic, non-reactive, not affected by water and can be applied to the skin for protection from ultraviolet light of the sun.

  • Patent number: 5602224
    Abstract: The invention relates to a series of novel silicone compounds which contain fatty alkyl groups. This class of compounds provides unique solubility in many organic softeners, and increases the effectiveness of the softening of fatty quats. These materials are applied to fibers including textile fibers and hair and skin. The compounds of the present invention contain which contain a fatty substituted quaternary group, a silicone group and a reactive silanol groups. The presence of the positive charge on the nitrogen results in substantivity to many substrates, the presence of a silicone portion results in compatability in silicone fluids and the presence of the fatty tail on the molecule results in fatty solubility. The resulting material is surface active and will allow for the incorporation of silicone into a fatty system or of a fatty quat in a silicone system.
