An ester of glycyrrhetinic acid with (poly)glycerol-sorbitol and cosmetic compositions thereof is described. The introduction of sorbitol in the (poly)glycerol chain determines an increase in solubility of the ester of the invention increasing solubility in water and the possibility of using glycyrrhetinic acid in cosmetic applications.
The present invention generally relates to a process for making polyol ethers by reacting a polyol and a carbonyl compound together in the presence of hydrogen gas and a palladium hydrogenation catalyst on an acidic mesoporous carbon support.
