  • High purity branched alkylsilsesquioxane fluids
    Patent number: 5932231
    Abstract: The invention provides high purity branched alkylsilsesquioxane containing fluids of the general formula Me.sub.3 SiO--(Me.sub.3 SiORSiO).sub.x --SiMe.sub.3, wherein Me is methyl, R is a monovalent hydrocarbon substituent, and x is 1 to 6, and an essentially zero waste process for their synthesis in quantitative yield; and especially n-octylsilsesquioxane containing fluids which are structural analogs of phenylsilsesquioxane containing fluids of the general formula Me.sub.3 SiO--(Me.sub.3 SiOPhSiO).sub.x --SiMe.sub.3, wherein Me is methyl, Ph is phenyl, x is 1 to 6, and have substantially identical sensory properties to their phenylsilsesquioxane counterparts.
    Type: Grant
    Filed: July 11, 1997
    Date of Patent: August 3, 1999
    Assignee: PCR, Inc.
    Inventors: Gary E. LeGrow, William I. Latham, III
  • High purity alkoxytrimethylsilane fluids
    Patent number: 5847179
    Abstract: The invention provides high purity alkoxytrimethylsilane fluids of the general formula ROSiMe.sub.3 wherein Me is methyl and R is a monovalent aliphatic hydrocarbon substituent which ranges from 14 to about 20 carbons, the fluid being substantially free of organic and inorganic contaminants, wherein the alkoxytrimethylsilanes are produced by a novel process, and can be readily incorporated into cosmetic formulations containing organic components without heating and provide improved sensory characteristics compared to those provided by the corresponding alcohols.
    Type: Grant
