Abstract
A block copolymer of the formula hydrocarbon-polyether-polyamide-polyether-hydrocarbon is described. The copolymer may be prepared by reacting together reactants that include dimer acid, diamine, and a polyether having both hydrocarbon termination and termination selected from one of amine, hydroxyl and carboxyl. The copolymer may be combined with a solvent to form a gel, where the gel may be transparent and may be incorporated into household and consumer products including antiperspirants.
