Euxyl K 903

Euxyl® K 903 is a complete preservative system with a broad, balanced spectrum of efficacy against both Gram-positive and Gram-negative bacteria, yeast and mold.  It is a typically biostatic product with the biocidal properties necessary for practical use. It is paraben free and formaldehyde free.

The combination of benzyl alcohol with organic acids in Euxyl® K 903 is an extremely effective preservative, yet gentle enough for eye-area products where the reduction of sting potential is important. Euxyl® K 903 is also an excellent choice for use in baby wipes and other products, where gentleness to the skin is required.

The natural tocopherol in Euxyl® K 903 is GMO-free and complies with the criteria of NATRUE and COSMOS (including Ecocert) for natural products.

The efficacy of the organic acids in Euxyl® K 903 depends on the pH-value. The efficiency is increased by reducing the pH-value.  Only the free organic acids are biocidal active.  The dissociated organic acids are completely ineffective.

As always, good production hygiene, as well as the use of raw materials with low microorganism levels as a result of correct raw material control are, of course, vital prerequisites for the production of microbiologically faultless finished products.
