Like the wings on maple seeds that boost seed dispersal, natural evolution produces organisms uniquely suited for their environment or function. Inspired by this efficiency, schülke has created sensiva® PA 40, an antimicrobial stabilizer blend uniquely suited for your leave-on, wet wipe and sensitive formulas. It combines natural, nature-identical and gentle synthetic materials to produce a multifunctional additive empirically designed to meet the changing preservation needs of the personal care industry.
As more traditional preservatives are coming under attack, formulators are looking towards multifunctional additives with antimicrobial stabilizing properties to fill the void. sensiva® PA 40 builds on schülke's experience and the success of our half natural, half nature-identical sensiva® PA 30.
Naturally occurring substances tend to be more organism-specific and can have color and odor issues. By using nature-identical and gentle synthetic materials, activity level, color and odor of sensiva® PA 40 can be controlled precisely and standardized. The consistency and availability of the material can also be managed to create a more sustainable formulation.
sensiva® PA 40 includes Zemea® Propanediol, from Dupont Tate & Lyle BioProducts. This innovative, skin-friendly, 100% natural glycol alternative is used as a humectant or natural solvent in cosmetics and personal care products. Studies have shown that Zemea® can boost the efficacy of preservatives, potentially reducing the amount of preservatives needed in the formulation. In this unique blend, propanediol improves the antimicrobial activity of the other ingredients, allowing sensiva® PA 40 to be used at lower levels than most non-traditional preservation systems.
Challenge tests performed on a variety of cosmetic formulations show sensiva® PA 40 to be an effective antimicrobial stabilizer at a use level of 0.5-1.5%. Additionally, it supports deodorant activity, as it has been shown to inhibit the growth and multiplication of odor-causing bacteria.
