<p>The invention concerns an organic sol characterised in that it comprises titanium oxide particles; an organic liquid phase and at least an amphiphilic compound selected among polyethylene phosphate alkyl ethers. In a first embodiment, the method for preparing said sol is characterised in that it consists in mixing said amphiphilic compound and the organic liquid phase, then in dispersing the titanium oxide particles in the resulting mixture. In a second embodiment, it consists in forming a mixture of titanium oxide and at least said amphiphilic compound, then in dispersing said mixture in said liquid phase. The invention also concerns a solid compound comprising a mixture of titanium oxide particles and at least an amphiphilic compound selected among those mentioned above.</p> |
