Sodium Ascorbate ●
TL;DR. This ingredient is a water-soluble antioxidant and skin-conditioning agent. It helps limit oxidation in formulas and is also used in brightening or tone-evening products.
What does Sodium Ascorbate do in a cosmetic formula?
This ingredient is a water-soluble antioxidant and skin-conditioning agent. It helps limit oxidation in formulas and is also used in brightening or tone-evening products.
Is Sodium Ascorbate clean?
It is generally well tolerated and has little clean-standard friction. Compared with more acidic related materials, it is less likely to sting, though oxidation can reduce performance and cause color shift in a formula.
Is Sodium Ascorbate sustainable?
This material is typically made from carbohydrate-based feedstocks through fermentation and further conversion steps. It is water-soluble, readily biodegradable, and not associated with environmental persistence concerns.
Is Sodium Ascorbate COSMOS-approved?
It is generally permitted under COSMOS natural and organic standards when the grade and manufacturing route meet the standard’s requirements. Its Green Chemistry profile is favorable because it can come from bio-based feedstocks, is biodegradable, and does not require persistent chemistry.
How does Sodium Ascorbate work chemically?
The molecule is a sodium salt of a six-carbon enediol lactone, which makes it highly water-soluble and less acidic than its protonated parent compound. Typical use ranges from about 0.1 to 2% for antioxidant support and higher in some treatment products, with best stability in low-oxygen, light-protected systems supported by chelators and compatible pH control.
