Abstract
The present invention relates to a high protection UVA/UVB composition comprising (a) about 0.5 to about 7.5% by weight of phenylbenzimidazole sulfonic acid; (b) about 0.1 to about 2.5% by weight of triethanolamine; (c) about 1 to about 11% by weight of an UVA chemical filter; (d) about 10 to about 50% by weight of an additional chemical filter; and (e) about 40 to about 70% by weight of an alcoholic carrier, wherein all percentages are based on the total weight of the high protection UVA/UVB composition and the water is not present. This composition have a high SPF and an appropriated PPD having a fluid and transparent aspect and having pleasant sensory characteristics. Furthermore, the present invention relates to a Process for preparing said high protection UVA/UVB composition comprising the following steps: (i) solubilize triethanolamine in alcoholic carrier, and (ii) when stirring, add phenylbenzimidazole sulfonic acid to the mixture obtained in step (i); (iii) in parallel, heat the additional chemical filters at a temperature ranging from about 50 to about 70° C., preferably about 60° C.; (iv) remove from the heating the mixture obtained in step (iii) and when it is at a temperature ranging from about 30 to about 50° C., preferably about 40° C., add it to the mixture obtained in step (ii); and (v) stir to obtain the final composition.
