摘要:
The invention concerns an organic sol characterised in that it comprises cerium oxide particles, an organic liquid phase and at least an amphiphilic compound selected among carboxylic acid polyoxyethylene alkyl ethers, polyethylene phosphate alkyl ethers, dialkyl sulphosuccinates and quaternary ammonium compounds. In a first embodiment, the method for preparing the sol is characterised in that it consists in mixing said amphiphilic compound and the organic liquid phase, then in dispersing the cerium oxide particles in the resulting mixture. In a second embodiment, the method consists in forming a mixture of cerium oxide and at least one said amphiphilic compound, then in dispersing said mixture in said organic liquid phase. The invention also concerns a solid compound comprising a mixture of cerium oxide and at least an amphiphilic compound selected among those mentioned above.
