schülke focused on two stabilization methods with the aim of finding optimal solutions for the protection of sunscreen products. The preservative euxyl® PE 9010 (Phenoxyethanol + Ethylhexylglycerin) was tested along with the multifunctional sensiva® PA 40, a blend of natural, nature-identical and gentle synthetic materials. While both systems were able to effectively stabilize the sunscreen with the addition of a sufficient level of chelating agent, sensiva® PA 40 was effective at lower concentrations. It can be used at 1.5% to effectively protect this system without the need for any additional boosting.
Let the experts at schülke help you preserve and protect your most demanding products.
