What it is — Dehydroacetic Acid (INCI: Dehydroacetic Acid) is an organic-acid preservative used to protect formulas from microbial growth.

What it does — It is commonly used at low levels to inhibit mould and yeast and to help keep water-containing products fresh over their shelf life.

Typical use — It appears in toners, serums, creams and cleansers, often alongside other preservatives.

Who it suits / good to know — Preservation is essential for product safety. It has some mild irritation potential in sensitive users, so those prone to preservative reactions may want to check the label.

Safety — DHALIORA grades it mid risk: a common preservative with mild irritation potential in sensitive users. This reflects the ingredient in general and is not medical advice; patch-test before wider use if your skin is reactive.

Why we grade it Mid: Common preservative with mild irritation potential in sensitive users (EWG 3-4).
