Product information "Preservative K903"
Preservative K903
INCI: benzyl alcohol, benzoic acid, dehydroacetic acid and tocopherol
K903 is an effective preservative at low concentrations for all rinse-off and leave-on products.
Just like all other weak organic acids, its efficacy is extremely pH dependent and optimum application pH is pH<6. (we recommend 5.0-5.5)
In the EU there is a limitation for benzoic acid and benzyl alcohol concentration and the max. allowed concentration for K903 is 1,23%. Keep that in mind if you're applying other ingredients that are preserved with benzyl alcohol or benzoic acid.
Since the preservative has lipophilic components, it is not completely water soluble. In products without an oil phase (lotions) or a surfactant (shampoo, facial cleansing foam) you'll need a solubilizer to incorporate it into water. Technically it is possible to use a solubilizer like natural solubilizer clear plus for this purpose. We recommend however to use this preservative only in lipid containing formulations (lotions, balms) to avoid sensitization.
