What Sodium Anisate does

Helps keep products free from bacteria
Helps limit yeast and mold growth
Dissolves easily in water-based formulas

Anisic acid is a small molecule found naturally in anise and some other plants. Sodium Anisate is made by combining anisic acid with a sodium base, which turns it into a salt that dissolves easily in water. That makes it easier to work with in water-based products than the acid form.

Formulators use it mainly as a preservative. Water-based creams, lotions and cleansers can support the growth of bacteria, yeast and mold over time, so a preservative helps keep them stable on the shelf. Sodium Anisate is often combined with other preservatives and used in small amounts.

Good for

Good for formulas that contain water, such as lotions, cleansers and toners, where a preservative helps protect against spoilage.
