Erythorbic Acid is the stereoisomer of ascorbic acid. In finished formulas it is not ascorbic acid and not sodium ascorbate. This grade is a white to off-white crystalline powder that dissolves in water.

Antioxidant serums continue to specify this INCI when erythorbic acid is named. Cosmetic-grade material remains a bulk ingredient when the assay is on the COA.
