Cosphagard® Pol is a cost-efficient mixture of Potassium Sorbate and the naturally derived multifunctional sodium levulinate. The blend can be used to replace controversially discussed Preservatives like parabens, MIT, triclosan, formaldehyde separators etc. without losing strong antimicrobial effectiveness against bacteria, yeasts and molds. A further advantage is that this blend is COSMOS-approved and also complies with further international certification labels. It can be used for any cosmetic formulation type except purely oil-based formulations. For full efficiency the pH value of the final product should ideally be 5.5.
