ABSTRACT:
A skin tanning composition comprising (a) 5 to 50% by weight of an oil fraction of straight or branched paraffinic oils of 10 to 30 carbon atoms with a boiling range of 100.degree. to 500.degree. C. at atmospheric pressure and a viscosity of at most 35 centistokes at 25.degree. C., optionally containing up to 6% by weight of esters of optionally unsaturated higher natural fatty acids and optionally unsaturated natural aliphatic alcohols of up to 20 carbon atoms, (b) 1 to 10% by weight of an emulsifying system comprising (1) 1 to 10% by weight of mono and/or diglycerides of higher optionally unsaturated natural fatty acids and (2) ethoxylated glycerides esterified with fatty acids of the formula ##STR1## wherein n is an integer from 5 to 20 and the R's are individually an optionally unsaturated fatty acid residue derived from animal or vegetable oils with a ratio of 10 to 100 parts by weight of (1) per part by weight of (2), (c) (1.0 to 5% by weight of a mixture) 1 to 5% by weight of panthenol and 0.5 to 5% by weight of tyrosine or tyrosine precursor in a molar ratio of 2:1 to 1:3 of tyrosine or tyrosine precursor to panthenol, (d) sufficient alkali to maintain the pH of the aqueous phase at 4 to 7, (e) 0.2 to 4% by weight of a montmorillonite stablizer with free oxygen sites occupied by quaternary groups, (f) 0.5 to 1.0% by weight of a preservative for the formed continuous phase and (g) water to make up 100% by weight, the weights being based on the weight of the entire composition to effect relatively fast skin tanning upon exposure to natural sun light or from artificial sun tanning equipment such as sunbeds and solaria while avoiding exposure to compounds which can disturb the biological equilibrium of the skin.
