Abstract:
In one embodiment, a personal-care composition in the form of a water-in-oil emulsion comprises at least about 10% of a non-polar silicone oil; from about 0.1% to about 10% of a first oil-soluble solid sunscreen; and from about 0.1% to about 10% of a second oil-soluble solid sunscreen. The weight ratio of the first sunscreen to the second sunscreen may be from about 0.8 to about 2.0, or from about 1.0 to about 1.5. The first sunscreen may be oxybenzone. The second sunscreen may be avobenzone. The composition may further comprise a skin-care active selected from the group consisting of a vitamin B3 compound, a sugar amine, a peptide, a hexamidine compound, and combinations thereof. In another embodiment, the invention relates to a method for improving the solubility of a second oil-soluble solid sunscreen in the oil phase of a water-in oil emulsion.
