  • Silicone surfactants
    Patent number: 4988504
    Abstract: Certain polysiloxane surface active agents containing radial organic polyether groups provide for improved stability of silicone emulsions, particularly antiperspirant stick compositions.
    Type: Grant
    Filed: August 19, 1987
    Date of Patent: January 29, 1991
    Assignee: General Electric Company
    Inventors: Anthony A. Zotto, Raymond J. Thimineur, William J. Raleigh
  • Antiperspirant compositions
    Patent number: 4980156
    Abstract: An improved dry-feeling antiperspirant composition is provided which comprises an aqueous solution of an astringent emulsified in a volatile silicon fluid, the emulsion being stabilized by a combination of a long-chain alkyl modified polysiloxane-polyoxyalkylene copolymer and an organic surfactant having an HLB value from 8 to 18.
    Type: Grant
    Filed: December 12, 1988
