  • Silicone composition for skin care
    Patent number: 5759529
    Abstract: A composition for conditioning the skin which includes a silicone gum, a volatile methylsilicone fluid, and a volatile alkylmethylsiloxane. When applied to the human skin, the composition adsorbs approximately twenty percent faster, has a less greasy feel during application, and provides a coating on the skin which is smoother, than comparative products.
    Type: Grant
    Filed: November 4, 1993
    Date of Patent: June 2, 1998
    Assignee: Dow Corning Corporation
    Inventors: Gary Edward LeGrow, John Cyrus Smith, Jr.

  • Particulate inorganic oxide treated with cyclic polysiloxane
    Patent number: 5690860
    Abstract: The invention relates to a particulate silica or particulate titania which is treated with a cyclic polysiloxane having the formula ##STR1## in which Me represents a methyl radical and R is an alkyl group having 2 to 12 carbon atoms, The treated particles can be uniformly dispersed in a non-polar organic medium to provide a system having greater stability than similar prior art dispersions,

  • Cyclic alkylmethylsiloxanes for skin care
    Patent number: 5679335
    Abstract: A method of treating human skin to decrease transepidermal water loss. A method of enhancing the substantivity of conditioning compounds applied to the skin. A film forming conditioning formulation which includes as an ingredient thereof an organosilicon compound is applied to the skin. The improvement resides in the utilization of a formulation which includes as the organosilicon compound a cyclic alkylmethyl polysiloxane.

  • Alkyl substituted siloxanes and alkyl substituted polyether fluids
    Patent number: 5670686
    Abstract: New alkyl substituted siloxanes and alkyl substituted polyether fluids are prepared by reacting an unsaturated alkyl, a aralkyl or ether with alkylhydrido siloxanes such as (i) comonomers RSi(OSiMe.sub.2 H).sub.3, (ii) oligomers (HMe.sub.2 SiO).sub.2 --Si(R)--O--Si(R)--(OSiMe.sub.2 H).sub.2, and (iii) higher molecular weight siloxane species RSi?(OSiMe.sub.2).sub.x OSiMe.sub.2 H!.sub.3 and ?HMe.sub.2 SiO(Me.sub.2 SiO).sub.x !.sub.2 Si(R)O(R)Si?(OSiMe.sub.2).sub.x OSiMe.sub.2 H!.sub.2. R is a C.sub.2 to C.sub.18 straight-chain or branched-chain alkyl substituent.
