Efficient by design

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 stabiliser blend uniquely suited for 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 stabilising 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 colour and odour issues. By using nature-identical and gentle synthetic materials, activity level, colour and odour of sensiva PA 40 can be controlled precisely and standardised. 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 stabiliser 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 odour-causing bacteria.

Schülke & Mayr GmbH has over 124 years of history protecting people and materials against infection and contamination. Its euxyl brand provides numerous preservative blends for the cosmetic industry. These optimised combinations of active substances offer broad-spectrum efficacy, keeping cosmetic products free of microbial growth.

The sensiva and sensidin brands include versatile, multifunctional skin care additives for personal care products. With their unique properties, they are suitable for use in a wide range of cosmetic applications, including creams, lotions and deodorants.

With sensiva PA 40, schülke has taken inspiration from Mother Nature. By combining natural, nature-identical and gentle synthetic components, sensiva PA 40 has improved the efficiency and efficacy of non-traditional preservation systems.
