Abstract: An oil-in-water composition is provided. The composition includes an oil-in-water wherein the emulsion includes a) one or more antioxidants, b) one or more SPF boosters, c) one or more acrylate-based polymer capable of stabilizing the composition, d) one or more organic UV filters, e) one or more thickeners, f) one or more film formers; and g) one or more emulsifiers. The oil-in-water composition is provided in which the composition is essentially free of oxybenzone.

Abstract: A sunscreen composition provided as a water-in-oil emulsion of aqueous and oil phases includes a combination of organic and mineral UV filters, and one or a combination of, each, of dispersing agents, film formers, emulsifiers, structuring agents, and aqueous and oil phase solvents. The sunscreen composition confers water-resistant broad-spectrum UV protection, is non-whitening, and demonstrates acceptable sensorial properties, and stability through a range of temperatures.

Abstract: An organic-mineral hybrid sunscreen composition is an oil-in-water emulsion of aqueous and oil phases. The oil phase includes at least one mineral UV filter comprising Zinc oxide, a blend of organic UV filters comprising ethylhexyl methoxycinnamate, ethylhexyl salicylate, octocrylene, and homosalate, at least one oil phase solvent, and at least one surfactant and the water phase includes water; at least one water-miscible solvent, and at least one polymer, and at least one filler. The organic-mineral hybrid sunscreen composition has an SPF of at least about 30 and a critical wavelength of at least 370 nm.

Abstract: A sunscreen composition in the form of a water-in-oil emulsion comprising: a) a water phase of about 20% to 60% by weight relative to the total weight of the sunscreen composition; b) one or more mineral UV filtering agents; c) one or more oil thickening agents selected from poly C10-30 alkyl acrylate, hydrogenated jojoba oil and its derivatives and mixtures thereof; wherein the total amount of oil thickening agents is about 0.5% to about 4% by weight relative to the total weight of the sunscreen composition; wherein when hydrogenated jojoba oil is present, the amount of hydrogenated jojoba oil is no more than 1.5 times the amount of poly C10-30 alkyl acrylate; wherein the composition has a viscosity of about 0.1 Pa·s to about 5 Pa·s at 25° C. at 10 rad/s; and wherein the inflection point of the largest viscosity transition at 10 rad/s is between 30° C. to 40° C.
