What Is Sodium Succinate?
Sodium succinate is the sodium salt of succinic acid, a fermented or synthetically produced acid used primarily in cosmetics to adjust a formula’s pH. Like its parent ingredient, sodium succinate serves the same function in skin care products.
The highest reported concentration of sodium succinate in a cosmetic product was 26% in a bath product that is meant to be diluted before use. The independent Cosmetic Ingredient Review panel has ruled sodium succinate safe in its current usages.
