Abstract

The invention relates to cosmetic hair care preparations containing: (a) water soluble &bgr;-(1,3) glucans which are substantially devoid of &bgr;-(1,6) links, and (b) polymers. The addition of the special glucans to the polymers reduces the formation of stress-cracking in the polymer films when the preparation is absorbed by the hair.
