Abstract:
UV-protection composition comprising:solid, polymorphic lipid particles that are crystalline or partially crystalline, optionally in the form of a solid inner phase (lipid phase) dispersed in an outer liquid phase, wherein the solid polymorphic particles have an endothermic peak above 20Â° C. during the heating-up phase in heat calorimetry (DSCâ€”differential scanning calorimetry) and have a size (average value of the main population) in the range of 10 nm to 1000 nm, and wherein the polymorphic particles comprise at least one selected from the group consisting of natural and synthetic mono-, di- und triglycerides, their mixtures, fatty alcohols, ethers of the same, individually or in a mixture, cetyl palmitate, glycerol monostearate, glycerol palmitostearate, glycerol ricinoleate, glycerol tribehenate (Compritol), gly-cerol trilaurate, hard fat (Witepsols), microcrystalline triglycerides (Dynasanes), and stearyl alcohol, individually or in a mixture.
