Liquid fiber-treating and skin-treating compositions include surfactant, water insoluble treating material, water and long chain alcohol or derivative thereof, which stabilizes the liquid so as to allow storage at elevated temperatures, such as those which can be reached during storage in warmer climates, and which also helps to make fiber- and skin-treating materials more substantive to fibers and skin. Among the various types of compositions benefited are shampoos, perfuming shampoos, hair conditioning compositions, hair setting compositions, anti-dandruff preparations, fabric softening compositions, antistatic compositions, detergents, skin cleansers, skin lotions and sunscreens.
A hair treating composition which is a stable aqueous emulsion, suspension or dispersion of a water insoluble hair treating material, said material being selected from the group consisting of beeswax, petrolatum, paraffin wax, isoparaffin, mineral oil, microcrystalline wax, silicone, perfume, quaternary ammonium salt, amine antistatic agent, polyethylene, C.sub.18-36 triglyceride, higher fatty alcohol ester of higher fatty acid, and sunscreening compound, and mixtures thereof, said composition comprising 0.3-10% of said water insoluble hair treating material, 0.3-35% of anionic surface active agent, and 0.5-10% of a stabilizing agent for the composition, said stabilizing agent being selected from the group consisting of long chain primary alcohols, of a weighted average number of carbon atones in the range of 26 to 43, alkoxylated such alcohols fatty acids of a weighted average number of carbon atoms in the range of 26 to 43 and primary lower alcohol esters of said fatty acids in which the alcohol is of 1 to 4 carbon atoms, and mixtures thereof.
