Potassium Benzoate

Low risk

FunctionPreservative

What it is — Potassium Benzoate (INCI: Potassium Benzoate) is a preservative, the potassium salt of benzoic acid.

What it does — It is commonly used to help protect a product from microbial growth and keep it fresh over its shelf life, working best in lower-pH formulas.

Typical use — Found in toners, serums, creams and a wide range of leave-on and rinse-off products.

Who it suits / good to know — Broadly suitable; it is a background preservative rather than a skin active and is often used in “gentler-preservative” systems.

Safety — DHALIORA grades it low risk in its EWG-style, ingredient-by-ingredient review. This reflects the ingredient in general and is not medical advice; patch-test if your skin is easily irritated.
