The present invention relates to emulsion-based sunscreen compositions, including only inorganic ultraviolet radiation (UV)absorbers. Specifically, it relates to sunscreen compositions in the form of oil-in-water (O/W) and water-in-oil (W/O) emulsions that contain inorganic UV-absorbers and an SPF-boosting additive. The sunscreen compositions include an emulsion of an oil phase and a water or hydrophilic liquid phase, an inorganic UV-absorber in the oil phase, and an additive in the water or hydrophilic liquid phase, the additive capable of boosting the sun protection factor (SPF) of the sunscreen composition by at least 20%. |
