Effective, broad-spectrum, and cost-effective, plus it's suitable for natural cosmetics. What more could you ask for?

Benefits:

This blend of organic acids combined with the aromatic alcohol benzyl alcohol provides a broad-spectrum preservative effect and protects the formulation from spoilage. Benzyl alcohol interferes with certain membrane functions of microorganisms and, internally, inhibits vital enzymes. Benzoic acid also weakens microorganisms from within by lowering the intracellular pH, ultimately leading to cell death. In this way, microorganisms are attacked from both the outside and the inside, even at low concentrations.

Applications:

Evicide® BDA is a COSMOS-accepted preservative mixture suitable for use in aqueous products, surfactant-based formulations, and emulsions. In some cases, pre-neutralization is necessary to achieve good solubility of the organic acids. After pre-neutralization, the pH should be adjusted to <6 for effective preservative action.
