An ester-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 be mineral oil. A solid coating may be placed around the candle, for advantages including to enhance the clarity and/or 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 ester-terminated dimer acid-based polyamide may also be combined with an active ingredient, such as a fragrance, colorant, insect-repellant, insecticide, bioactive ingredient or the like, to afford a delivery vehicle for the active ingredient.

An ester-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 be mineral oil. 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 ester-terminated dimer acid-based polymer forms a gel, may be or include a fragrance material, an insecticide or an insect repellent. A wick may or may not be present in this gel, but in any event, the composition provides for the release of the fragrance, insecticide or insect-repellent.

The present invention is directed to a stable fragrant bleaching composition which comprises (a) a bleaching agent having a reduction potential from about -0.7 v to about +0.4 v; and (b) an organoleptic effective amount of a fragrant agent which is (i) stable to the bleaching agent; (ii) does not decompose the bleaching agent; and (iii) is not substantially hygroscopic. This invention also pertains to methods for making and employing the stable fragranced bleaching compounds.
