Product Description
Green Stone Swiss supplies high-purity Sodium Ascorbate manufactured under strict GMP-aligned quality systems, ensuring consistent batch-to-batch performance for professional cosmetic and personal care brands worldwide. Our direct factory supply model delivers reliable bulk quantities with full technical documentation and free sample support.
Sodium Ascorbate is the sodium salt of ascorbic acid. In leave-on and rinse-off care it is used as a water-soluble vitamin C salt, not as free ascorbic acid. This grade is a white to pale yellow crystalline powder that dissolves in water.
Toners and gel serums continue to specify this INCI when the formula needs vitamin C in a salt form. Cosmetic-grade Sodium Ascorbate remains a practical bulk active when the assay is on the COA.
