Polyamide-Polyether Block Copolymer

A personal care product, comprising a copolymer, at least one physiologically acceptable liquid, and at least one cosmetic or dermatological agent, wherein the copolymer comprises:

• a polyamide-polyether block copolymer formed a reaction mixture comprising one or more diacid compounds comprising 1,4-cyclohexane dicarboxylic acid (CHDA) and one or more diamine compounds comprising poly (alkyleneoxy) diamine (PAODA), the reaction mixture containing at least one monofunctional compound reactive with amine groups wherein:
• a) the copolymer has a softening point that is at least 80° C. and not more than 130° C.;
• b) CHDA provides at least 60% of the acid equivalents from diacid compounds;
• and
• c) PAODA provides at least 50% of the amine equivalents from diamine compounds.
