Ascorbyl Tocopheryl Maleate links ascorbic acid and tocopherol through maleate. In emulsions it is an oil-phase specialty ester, not free ascorbic acid and not free tocopherol. This grade is a pale yellow to yellow viscous oil.

Creams continue to specify this INCI when one oil-phase material is meant to carry both vitamin fragments. Cosmetic-grade material remains a niche bulk ester when identity is on the COA.
