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.
This pH adjuster is also known as disodium succinate.
