The current invention is drawn to a series of citrate esters having alkyl groups and a silicone groups esterified onto citric acid. This results an outstanding skin feel, making outstanding waterproofing and emollient properties when applied to skin. A required critical element of the invention is that both the silicone and the alkyl material be mono functional with regard to hydroxyl functionality. If either group has more than mono functionality, they will react with the citric acid (which has three carboxyl groups) to give undesired polymers. The ability to vary the ratio of alkyl to silicone results an ability to alter skin feel and consequently provide the cosmetic formulator with more latitude in choosing ingredients for incorporation into formulations.
