Sodium Levulinate

Sodium Levulinate

The salt of levulinic acid, used as part of a gentle, naturally-positioned preservative-and-conditioning system.

What it does

Sodium levulinate is the sodium salt of levulinic acid, derived from plant sugars. It is used to help keep formulas fresh and to condition the skin surface, and it is frequently paired with sodium anisate as a 'natural' preservative blend. It also helps buffer pH. It is a preservation-and-conditioning ingredient rather than a skin active.
