Sodium Anisate

Description

Sodium Anisate is a nature-identical preservative derived from anise or fennel. This white, crystalline powder is increasingly popular in natural and organic cosmetic formulations due to its effectiveness and gentle profile. As the sodium salt of p-anisic acid, it exhibits broad-spectrum antimicrobial activity, protecting products against bacteria, yeast, and mold.

With a pH range of 6-8, Sodium Anisate is particularly suited for leave-on skincare products and water-based formulations. It works synergistically with other preservatives, enhancing overall product protection. Its efficacy is most pronounced in acidic environments, making it an excellent choice for formulations with lower pH levels.

Sodium Anisate is considered safe for use in cosmetics, with studies showing low irritation potential and good skin compatibility. It's biodegradable and Ecocert-approved, aligning with clean beauty trends. Typical usage levels range from 0.2% to 1%, depending on the formulation and desired preservation efficacy.

This preservative is odorless and colorless, ensuring it doesn't interfere with product aesthetics or fragrance. Its stability in various temperatures and compatibility with most cosmetic ingredients make it a versatile option for formulators seeking alternatives to traditional preservatives.
