Abstract: The invention provides a polyester based on dimeric fatty acid, a glycol without hydrogen atoms at an alpha carbon atom in which a C3-C12 monoalcohol chainstopper is present and which contains approximately equivalent quantities of acid and alcohol groups. Preferably the dimer acid contains 36 carbon atoms and the monoalcohol is a branched chain C6-C10 alkanol. The invention also provides lubricant compositions comprising 30-2% (w.w.) of the polyester and 70-98% (w.w.) of an synthetic lubricant base.

Abstract: The invention provides a composition of matter, which is suitable for manufacturing candles by pressing/extruding, which is based on stearic/palmitic acid and also comprises:0.2-10% (w.w) of a crystal modifier and optionally 0.5-15% (w.w) of another, as to carbon chain length adjacent, natural fatty acid and/or such fatty acid derivative. Preferably the stearic/palmitic acid is a mixture of stearic acid and palmitic acid in the weight range of 20-80:80-20.The crystal modifier is usually of the ester type and is derived from a polyol with 2-4 hydroxyl groups and higher fatty acid and/or dimeric fatty acid.
