schülke bridges the gap with euxyl® K 903
schülke announces the relaunch of its euxyl® K 903, now with natural tocopherol. This unique formulation was redesigned to meet the needs of formulators to have a preservative that is efficient and effective, yet is gentle enough for sensitive product applications. Based on naturally occurring ingredients, and now stabilized with natural tocopherol, euxyl® K 903 meets the requirements of many certification bodies, like NATRUE and COSMOS (including Ecocert).

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. euxyl® K 903 joins euxyl® K 712 in schülke's range of eco-friendly cosmetic preservatives.

The natural tocopherol is GMO-free and complies with the criteria of NATRUE and COSMOS (including Ecocert) for natural cosmetics. The efficacy and properties of the reformulated euxyl® K 903 remain the same.

Product description
euxyl® K 903 is a liquid cosmetic preservative which can be used in leave-on and rinse-off products, as well as for wet wipes. euxyl® K 903 was developed for use in cosmetic formulations with a skin-friendly pH value up to 6. euxyl® K 903 is particularly effective in nonionic systems.

Microbiological effectiveness
euxyl® K 903 has a broad, balanced spectrum of effect against bacteria, yeast and mold. It is a typically biostatic product with the biocidal properties necessary for practical use.

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.

euxyl® K 903 bridges the gap between efficacy and nature in modern preservation.
