Abstract
A tertiary amide-terminated dimer acid-based polyamide may be blended with a solvent to form a gel. The solvent may be flammable, and a wick may be added to the resulting gel so as to form a candle. Depending on the composition, the candle may be formed into a free-standing pillar, or may be better suited to being placed in a container. The solvent may, for example, be mineral oil or triglyceride. A solid coating may be placed around the candle, for advantages including to enhance the mechanical stability of the gelled body, and to eliminate the tendency of a gel to have an oily feel and to accept noticeable fingerprints. The solvent which, in combination with the tertiary amine-terminated dimer acid-based polymer forms a gel, may be or include a fragrance material. The gelled composition may also include fatty acid and/or a compound containing one, two, or more ester groups. In one aspect, the article does not contain a wick, and is intended to function as a fragrance-releasing product.
