Abstract
An organic sol containing: cerium oxide particles; an organic liquid phase; and at least one amphiphilic compound chosen from polyoxyethylenated alkyl ethers of carboxylic acids, polyoxyethylenated alkyl ether phosphates, dialkyl sulphosuccinates and quaternary ammonium compounds. A process for preparing the sol is characterized in that the abovementioned amphiphilic compound and the organic liquid phase are mixed together and the cerium oxide particles are then dispersed in the mixture obtained. According to a second variant, a mixture of cerium oxide and of at least one abovementioned amphiphilic compound is formed and the said mixture is then dispersed in the organic liquid phase.
