Abstract
Non-aqueous waterproof oil-based topical compositions containing one or more water-in-oil emulsifiers having an HLB value of about 1 to about 7, e.g., sorbitan sesquioleate, and at least one cosmetic emollient, e.g., extra heavy mineral oil, as well as methods for making such compositions are disclosed. The waterproof compositions are particularly useful as vehicles for non-aqueous waterproof oil-based topical sunscreen compositions.
