ABSTRACT:
The invention relates to polysiloxanes with 1) at least two polyether groups A and B, polyoxyalkylene group, with an average molecular weight of 600 to 5,500, consisting of 20 to 100% by weight of oxyethylene units and of 80 to 0% by weight of oxypropylene units and the polyoxyalkylene group B, with an average molecular weight of 700 to 5,000, consisting of 0 to <20% by weight of oxyethylene units and of 100 to 80% by weight of oxypropylene units, and with 2) hydrocarbon groups with 6 to 30 carbon atoms, linked to silicon. The invention further relates to the synthesis of these polysiloxanes and their use as additives for hair cosmetics, particularly as additives for hair shampoos to improve the handle and the combability of the hair.
