Patent

CA 2164814

Provides hair conditioning shampoo compositions suitable and safe for frequent (e.g., daily) use and contact with the hair and skin, said compositions comprising (a) one or more detersive surfactants such as those selected from the group consisting of anionic, nonionic, amphoteric, and zwitterionic surfactants; (b) a nonvolatile hair conditioning agent or combination of nonvolatile hair conditioning agents selected from the group consisting of insoluble silicones, water soluble organic cationic conditioning agents such as cationic-surfactants and cationic polymers; and (c) from about 20 % to about 99.5 %, by weight, water, wherein said composition additionally comprises from about 0.004M to about 0.08M of free polyvalent metal cations. The present invention can provide improved consistency of deposition on the hair for nonvolatile insoluble silicone and water soluble cationic conditioning agents when the composition is applied using water across a broad range of hardness.

Shampooings traitants convenant pour des usages répétés (p.ex. quotidiens) et pour un contact avec les cheveux et la peau, et comportant: (a) un ou plusieurs surfactants tels que ceux choisis dans un groupe de surfactants anioniques, non ioniques, amphotères et zwitterioniques, (b) un agent traitant ou une combinaison d'agents traitants non volatil(s) choisi(s) dans une groupe de silicones insolubles, d'agents traitants organiques cationiques hydrosolubles tels que des surfactants cationiques et des polymères cationiques; et (c) entre environ 20 % et environ 99,5 % d'eau en poids et enfin d'environ 0,004M à environ 0,08M de cations métalliques polyvalents libres. La composition objet de l'invention assure, lorsqu'elle est utilisée avec des eaux comprises dans une grande plage de duretés, une régularité améliorée des dépôts sur le cheveu des silicones insolubles non volatils et des agents traitants cationiques hydrosolubles.
