Our direct factory supply model delivers reliable bulk quantities with full technical documentation and free sample support.
Ascorbyl Dipalmitate is ascorbic acid esterified with two palmitic chains. In creams and anhydrous oils it is an oil-phase antioxidant, not a water-soluble vitamin C salt and not Ascorbyl Palmitate. This grade is a white to off-white waxy powder that disperses in oils.
Balms and night creams continue to specify this INCI when the oil phase needs a more lipophilic vitamin C ester. Cosmetic-grade Ascorbyl Dipalmitate remains a practical bulk antioxidant when the assay is on the COA.
