  • Patent number: 7285263
    Abstract: The invention relates to optically transparent compositions containing hydrophobic silicone oil and alkyl ether carboxylates that are useful e.g. as a hair treatment composition such as a shampoo. In particular, it provides an optically transparent composition comprising (a) a hydrophobic silicone oil; and (b) an alkyl ether carboxylate derived from alkanols having 6 to 22 carbon atoms; wherein the weight ratio of component (b) to component (a) is in the range of 1:1 to 20:1. The composition preferably also contains anionic surfactants as component (c), the total amount of the components (b) and (c) being preferably in the range of 10-25 wt.-% with respect to the total weight of the composition. The invention also provides a method for preparing the above composition.

  • Publication number: 20050235430
    Abstract: New dyeing compositions, containing improved levelling agents, for dyeing of keratinous fibres, especially human hair, making more uniform the colour of the dyed fibres, are provided. The compositions contain one or more compounds of the formulae (I) and/or (II), wherein R is an alkyl group or alkenyl group having 6 to 24 carbon atoms; R?, R? and R?? are independently a hydrogen atom or an alkyl group having 1 to 5 carbon atoms which is optionally hydroxylated; m has a value in the range of 4 to 10; n has a value in the range of 0 to 10; and p has a value in the range of 1 to 10, with the proviso that when p=1, at least one of R?, R? and R?? is not a hydrogen atom.

  • Patent number: 6803050
    Abstract: The invention relates to optically transparent aqueous compositions containing hydrophobic silicone oil and a comparably low amount of wash-active matter, being suitable as a hair treatment composition such as a shampoo. In particular, it provides an optically transparent aqueous composition comprising (a) a hydrophobic silicone oil in an amount of 1-3 wt.-% with respect to the total weight of the composition; (b) a solubilizer for the silicone oil; and (d) an anionic surfactant; wherein the weight-ratio of component (b) to component (a) is in the range of 1:1 to 12:1; and wherein the total amount of the components (b) and (c) is in the range of 10-25 wt.-% with respect to the total weight of the composition. The invention also provides a method for preparing the above composition.
