A low molecular weight, tertiary amide terminated polyamide may be blended with a liquid hydrocarbon to form a transparent composition having gel consistency, and this gel may be used to formulate a cosmetic. The tertiary amide terminated polyamide may be prepared by reacting "x" equivalents of dicarboxylic acid wherein at least 50% of those equivalents are from polymerized fatty acid, "y" equivalents of diamine such as ethylene diamine, and "z" equivalents of a monofunctional reactant having a secondary amine group as the only reactive functionality. The stoichiometry of the reaction mixture is preferably such that 0.9≤{x/(y+z)}≤1.1 and 0.1≤{z/(y+z)}<0.7. The gel contains about 5-50% tertiary amide terminated polyamide, with the remainder preferably being pure hydrocarbon.
