  • Patent number: 7279503
    Abstract: The invention relates to emulsions of the W/O (water/oil) type made using specific emulsifiers and oils selected from silicone oil, mineral oil and combinations thereof. Silicone emulsifier conforming to the following structure: wherein; a is an integer ranging from 2 to 10; b is an integer ranging from 2 to 10, such that b/a>or=1, but less than 2.5; c is (a+b) times x, wherein x is 1.5 to 2.5; d is an integer ranging from 6 to 12; are used to obtain the desired W/O (water/oil) type emulsion.

  • Patent number: 6407274
    Abstract: The present invention relates to silicone based amine oxides. The silicone amine oxides are non-irritating, high foaming products that are substantive to substrates like fiber, metal hair and skin. They also possess good detergency. They are made by reaction of a suitable silicone compound containing an epoxide functionality, followed by reaction with hydrogen peroxide to make the amine oxide.

  • 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.
