Organic sols and solid compositions based on titanium oxide and an amphiphilic compound useful for photocatalytic applications and in cosmetics, paint and plastic formulations

摘要

An organic sol is disclosed comprising titanium oxide particles; an organic liquid phase and at least am amphiphilic compound selected among polyethylene phosphate alkyl ethers. In a first embodiment, the method for preparing said sol mixes said amphiphilic compound and the organic liquid phase, and disperses the titanium oxide particles in the resulting mixture. In a second embodiment, the method forms a mixture of titanium oxide and at least said amphiphilic compound, then disperses said mixture in said liquid phase. A solid compound comprising a mixture of titanium oxide particles and at least an amphiphilic compound selected among these mentioned above is also disclosed.
