Sorbitan Caprylate for enhancing antimicrobial performance

Cosmetic formulations are prone to contamination due to their high water content, pH and temperature range and ingredients used, which can act as nutrients.

In the past, parabens, formaldehyde-donors or halogenated products were most frequently used to preserve the formulation. Due to different reasons, these preservative groups are in discussion and can be replaced by a combination of organic acids like benzoic acid, sorbic acid or anisic acid and sorbitan caprylate at a pH < 6.0.
