abstract |
The invention provides an antimicrobial washing composition, such as a hair shampoo, comprising: a) from 2 % to 50 % by weight surfactant, b) from 0.1 % to 5 % by weight polyethylenimine, and c) from 0.1 % to 3 % by weight piroctone olamine. The presence of polyethylenimine in the composition enhances the desposition of the active piroctone olamine onto the hair and skin. |
