To be or not to be... natural

schülke offers the best of both worlds

schülke is known for the quality and consistency of its preservative blends. schülke’s non-traditional, antimicrobial stabilizer blends are tested to the same high standards as its traditional systems. The sensiva® line contains blends of natural, nature identical and gentle synthetic material that can be used to maintain the microbiological stability of personal care products.

Half natural and half nature-identical, sensiva® PA 30 can prevent microbial contamination in a wide variety of formulations, both leave-on and rinse-off. sensiva® PA 40 works at levels similar to many traditional preservative blends. It can be used to prevent contamination even in hard-to-preserve systems, like high-SPF sunscreens.

One of schülke’s more traditional preservative blends, euxyl® K 903 contains nature-identical benzyl alcohol and organic acids. Now stabilized with natural tocopherol, it can be used in products formulated to be NATRUE and COSMOS (including Ecocert) compliant.

No one can fool Mother Nature, but nature-identical materials can come close. Chemistries found in nature that have the consistency of being synthetically produced make formulation safer and more effective.
