9 claims: 1 independent, 8 dependent

  1. 1
    A cosmetic or household composition characterized in that it comprises; a) a suitable carrier; and b) a volatile silicon compound, having a boiling point of no greater than about 260°C at 760mm, selected from:a) linear siloxanes where 1) X = 1 to 4, 2) total carbons ≦ 14, 3) R can be independently C₁-C₁₀ alkyl, trialkyl siloxy and 4) at least one R per molecule must be aryl, alkylaryl or aryl alkyl or C₁-C₇ hydroxyalkyl or - R₁ R₂ wherein R₁ = C₁-C₄ alkylene and R₂ = -O-R₃ wherein R₃ = C₁-C₅ alkyl or b) cyclic siloxanes wherein 1) Y = 1 to 4, 2) total carbons ≦14, 3) R can be independently C₁-C₁₀ alkyl, trialkyl siloxy and 4) at least one R per molecule must be C₁-C₇ hydroxyalkyl or -R₁ R₂ wherein R₁ = C₁-C₄ alkylene and R₂ = -O-R₃ wherein R₃ = C₁-C₅ alkyl or c) silanes where 1) Z = 1 to 4, 2) total carbons ≦14, 3) R can be independently C₁-C₁₀ alkyl, trialkyl (C₁-C₃) siloxy and 4) at least one R per molecule must be selected from aryl, alkyl­aryl, aroalkyl or C₁-C₁₀ alkyl or - R₁ R₂ where R₁ = C₁-C₄ alkylene and
  2. 2

  8. 8
    A composition according to Claim 7 which in addition contains a hair styling polymer.
  9. 9
    A composition according to Claim 8 wherein the volatile silicon compound is methoxy ethyl heptamethyl cyckitetrasiloxane.
