Kem Nat is an innovative preservative blend with broad spectrum efficacy for natural cosmetics. It is a synergistic combination of natural-identical benzyl alcohol and natural-derived glyceryl monoesters that boost the antimicrobial action and add emolliency. Kem Nat is gentle to the skin and effective against bacteria, yeasts & moulds.


Colourless and with very mild odour, it is effective in the broad pH range from 4 to 8. Kem Nat represents an ideal product for rinse-off & leave-on cosmetics. Kem Nat is an optimized combination of the well established cosmetic preservative benzyl alcohol with the high purity monoesters glyceryl caprylate and glyceryl undecylenate. These esters show antibacterial and antifungal activity and boost the preservative action of benzyl alcohol, providing broad spectrum efficacy against Gram-negative & Gram-positive bacteria as well as against yeasts and molds. Additionally Kem Nat is effective against Propionibacterium acne.
