  • Patent number: 7186774
    Abstract: The invention provides water-soluble or water-swellable copolymers obtained by free-radical copolymerization of A) acryloyldimethyltaurine and/or acryloyldimethyltaurates, B) optionally, one or more olefinically unsaturated, optionally crosslinking comonomers containing at least one oxygen, nitrogen, sulfur or phosphorus atom and possessing a molecular weight of less than 500 g/mol, C) one or more at least monofunctional, silicon-containing components capable of free-radical polymerization, the copolymerization D) taking place in the presence of at least one polymeric additive having number-average molecular weights of from 200 g/mol to 109 g/mol. The water-soluble or water-swellable copolymers of the present invention are useful in paper processing, laundry detergents, textile processing, petroleum extraction and formulating cosmetics.

  • Patent number: 7074395
    Abstract: Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds and polyhydric alcohols. The invention provides compositions comprising a) at least one quaternary ammonium compound, b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms, and c) at least one polyhydric alcohol having 2 to 6 carbon atoms. The resulting compositions have a low setting point or melting point, good solubility and dispersibility in aqueous media and a low flash point.

  • Patent number: 6919074
    Abstract: Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds essentially free of short-chain alcohols such as isopropanol. The novel composition comprises: a) at least one quaternary ammonium compound and b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms.
