Patent number: 7074395Abstract: 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.Type: GrantFiled: May 28, 2002Date of Patent: July 11, 2006Assignee: Clariant GmbHInventors: Robert Milbradt, Sonja Klein, Franz Xaver Scherl, Erich Gatter, Adelgunde Oberhauser

Patent number: 6919074Abstract: 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.Type: GrantFiled: May 28, 2002Date of Patent: July 19, 2005Assignee: Clariant GmbHInventors: Robert Milbradt, Sonja Klein, Franz Xaver Scherl, Erich Gatter, Adelgunde Oberhauser
