Abstract

The subject of the invention is a sterically stabilised dispersion of a hybrid inorganic-organic material in oil as a preparation for the protection against harmful effects of UV rays. The present invention refers to a new cosmetic material on the basis of composites of hybrid inorganic-organic coatings on TiO2 nanocrystalline particles or another metallic oxide with increased dispersibility in organic vehicles and decreased formation of free radicals. The basic nanocrystalline particles of TiO2 and the inorganic coating from the bridged silane are prepared by the sol-gel process. Molecules of an organic steric stabiliser are then covalently bound to the coating of the bridged silane, said stabiliser being selected from one of the following groups of compounds: higher fatty acids, linear polymers, cross-linked polymers, branched polymers and dendritic polymers. The presence of the steric stabiliser prevents the TiO2 particles to agglomerate, improves dispersibility in organic vehicles, increases water resistance of the preparation and allows the use of high concentrations of oily suspensions that provide for a high factor of protection against harmful effects of UV rays.
