What is Vitamin C Ascorbyl Tetraisopalmitate?
Ascorbyl tetraisopalmitate (CAS 183476-82-6), also known as tetrahexyldecyl ascorbate and abbreviated VC-IP, is a highly lipophilic ester form of Vitamin C used in cosmetic and pharmaceutical formulations.
Where is Vitamin C Ascorbyl Tetraisopalmitate used?
- Premium skincare: facial serums, sunscreens, anti-aging creams
- Oil-based and waterless formulations: stable active ingredient
- Cleansing balms, facial oils, lip treatments: effectiveness through shelf life
- Pharmaceutical topical preparations target skin oxidative stress.
Good to know: Unlike water-soluble ascorbic acid, it disperses in oils and emollients, enabling stable delivery into lipid-rich skin layers. It provides antioxidant protection and supports even skin tone without the instability of aqueous Vitamin C formats.
