Disodium Ascorbyl Sulfate is a sulfated disodium salt of ascorbic acid. In skin care it is a water-soluble vitamin C derivative, not free ascorbic acid and not sodium ascorbate. This grade is a white to off-white powder that dissolves in water.

Toners continue to specify this INCI when a salt form of vitamin C is preferred. Cosmetic-grade Disodium Ascorbyl Sulfate remains a bulk active when the assay is on the COA.
