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 &ldquo;x&rdquo; equivalents of dicarboxylic acid wherein at least 50% of those equivalents are from polymerized fatty acid, &ldquo;y&rdquo; equivalents of diamine such as ethylene diamine, and &ldquo;z&rdquo; 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&lE;&lcub;x/(y&plus;z)&rcub;&lE;1.1 and 0.1&lE;&lcub;z/(y&plus;z)&rcub;<0.7. The gel contains about 5-50% tertiary amide terminated polyamide, with the remainder preferably being pure hydrocarbon.

Rosin esters that are both light-colored and color stable may be produced by reacting rosin with an organic compound containing two or more hydroxyl groups each separated from each other by at least four carbon atoms. With appropriate choices for the esterification catalyst and antioxidant(s), the rosin ester may be useful as a tackifier, and can be formulated into an adhesive composition. The adhesive compositions will further comprise an appropriate adhesive polymer.

Anthraquinone is removed from tall oil or tall oil fraction by adsorption with activated carbon. The process is particularly useful in the removal of anthraquinone from tall oil heads.
