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.
L'invention concerne des compositions optiquement transparentes contenant de l'huile de silicone hydrophobe et des carboxylates d'éther d'alkyle s'utilisant par ex. comme composition de traitement capillaire telle qu'un shampooing. L'invention concerne notamment une composition optiquement transparente contenant (a) une huile de silicone hydrophobe ; et (b) un carboxylate d'éther d'alkyle dérivé d'alcanols ayant entre 6 et 22 atomes de carbone. Le rapport en poids du constituant (b) au constituant (a) est de l'ordre de 1:1 à 20:1. Ladite composition contient également de préférence des tensioactifs anioniques comme constituant (c), la quantité totale des constituants (b) et (c) se situant de préférence dans une fourchette comprise entre 10 et 25 % en poids par rapport au poids global de la composition. L'invention concerne par ailleurs un procédé permettant de préparer ladite composition.
