Suitable components (a) can be obtained by the free radical addition of C 2 to C 18 monocarboxylic acids with olefin mixtures comprising C 20+ alpha-olefins and suitable components (b) can be obtained by the reaction of palmitic and/or stearic acid with azelaic acid and glycerol. The three components can be blended together in the molten state to produce a blend having a melting point of 55-75‹ C. The blends are used in cosmetics such as lipsticks and creams. A cream emulsion comprises 20 g. of the blend, 50 g. of mineral oil, 33À5 g. of water and 1 g. of either borax or triethanolamine.
