Glyceryl Diisostearate/Hydrogenated Rosinate

What is Glyceryl Diisostearate/Hydrogenated Rosinate?

Glyceryl Diisostearate/Hydrogenated Rosinate is a formulated blend of two esters used in cosmetics. Glyceryl diisostearate results from reacting glycerol with isostearic acid, a branched fatty acid typically derived from vegetable oils like rapeseed. Hydrogenated rosinate originates from rosin, a natural resin extracted from pine trees, which undergoes esterification and hydrogenation for stability and reduced reactivity. This ingredient appears mainly in color cosmetics such as lipsticks, mascaras, and eyeliners, belonging to the emollient and thickener category. It functions by depositing a thin, flexible film on the skin that locks in moisture and promotes smoothness. Simultaneously, it modifies the product's flow properties, increasing thickness to prevent separation, enhance application ease, and provide a glossy, adherent finish that improves product performance on skin and hair.
