  • Patent number: 5919441
    Abstract: An invention is disclosed which comprises gelling agents which (1) contain both siloxane groups and hydrogen-bonding groups to thicken compositions containing silicone fluids (volatile and/or non-volatile silicone fluids); (2) are non-flowable solids at room temperature; and (3) dissolve in a fluid which contains silicone at a temperature of 25-250 degrees C to form a translucent or clear solution at a temperature in this range. Cosmetic compositions may be made by adding at least one active ingredient such as an antiperspirant.

  • Patent number: 5874069
    Abstract: A base composition and corresponding cosmetic composition are disclosed which can be formed as solids (for example, gels or sticks) and which comprise a solvent which includes a silicone fluid (for example, a silicone oil such as cyclomethicone) and a thickening agent formed from a wax and a polyamide gellant wherein at least one of the wax and polyamide includes silicon-containing moieties (for example, siloxane groups to have a siloxane diamide wax to enhance compatibility of the silicone fluid in the composition. A cosmetically active material, such as a deodorant or antiperspirant active material, is included in the composition to form a solid cosmetic product (antiperspirant or deodorant product), which can be a clear product. Compositions of the present invention can be made with increased amounts of silicone fluid and with improved aesthetics such as decreased tack.
