摘要： The present invention refers to compositions based on clays, oils and/or plant extracts with photoprotective and/or antioxidant activity and inorganic sunscreens; formulations including photoprotective compositions; methods of preparation and their uses. Problem to be solved : provide hybrid compositions between organic and inorganic photoprotective ingredients, which do not require the use of nanoparticle or synthetic chemical sunscreens, which provide adjustable degrees of SPF and FPUVA and that allow obtaining photoprotective formulations in different pharmaceutical or cosmetic forms.
Problem resolution : Photoprotective compositions containing at least one clay, at least one oil and/or plant extract with photoprotective and/or antioxidant activity, and at least one inorganic sunscreen are revealed; being said clay is present in the composition in a concentration of 0.1 to 85% by weight; being said oil and/or plant extract is present in the composition at a concentration of 0.2 to 80%, by weight; and being said inorganic sunscreen is present in the composition at a concentration of 0.5 to 75%, by weight. Still, a photoprotective formulation is revealed - as well as its method of preparation - including said photoprotective composition.
