About
A cholesterol derivative where isostearic acid is linked via a carbonate bond — provides a smooth, powdery skin feel and works as an emollient and skin-conditioning agent.
Cholesteryl Isostearyl Carbonate is the carbonate ester of cholesterol and isostearyl alcohol. Carbonate esters are relatively stable linkages that resist hydrolysis better than standard carboxylic acid esters. The combination of cholesterol (a skin lipid) and isostearyl alcohol (a branched, mild fatty alcohol) yields an ingredient with excellent skin compatibility and a distinctive silky-powdery sensory profile. It is listed in CosIng with the function 'skin-conditioning - emollient' and is not restricted in EU Annexes.
