New Antimicrobial Stabilizers Made with Zemea® Propanediol

Wilmington, Del. (PRWEB) September 24, 2013

DuPont Tate & Lyle Bio Products Company LLC is excited to announce that Schülke & Mayr GmbH has expanded its sensiva® line of multifunctional additives. The latest additions to this line, sensiva® PA 30 and sensiva® PA 40, both feature the natural, preservative-boosting ingredient, Zemea® propanediol.

     Zemea® is a natural, 100 percent biobased ingredient made from corn starch through fermentation and developed for use in the cosmetics and personal care market. It is a high-performance, environmentally friendly sustainable alternative to petroleum-based glycols and glycerin, where the product’s lack of skin irritation, improved moisturization and excellent sensory properties are benefits. Zemea® is approved as a natural ingredient by Ecocert and the Natural Products Association; it is certified 100 percent biobased by the U.S. Department of Agriculture and has both Kosher and Halal certifications.

     Schülke’s sensiva® PA 30, combines the antimicrobial activity of two nature-identical fragrance ingredients with the boosting and skin care properties of naturally derived Zemea® propanediol, for a soft preservative system that is ideal for leave-on, rinse-off, wet-wipe and sensitive skin applications. Challenge tests performed on a variety of cosmetic formulations show sensiva® PA 30 to be an effective antimicrobial stabilizer at a use level of 1-2 percent. Additionally, it supports deodorant activity as it has been shown to inhibit the growth and multiplication of odor-causing bacteria. This combination of naturally derived and nature-identical ingredients makes it an excellent choice for nature-inspired cosmetics.

     sensiva® PA 40 is the most recent evolution of the sensiva® line of multifunctional additives. It combines a nature-identical fragrance ingredient with the boosting of naturally derived Zemea® propanediol and adds a gentle synthetic for additional skin care properties and better antimicrobial efficacy. This combination allows sensiva® PA 40 to be used at levels similar to more traditional preservative blends, while remaining gentle to the skin. Like other products in the sensiva® product line, sensiva® PA 40 has been proven to inhibit the growth and multiplication of odor-causing bacteria. This multifunctional product can be used in leave-on, wet-wipe and sensitive skin applications at a use level of 0.5-1.5 percent to help maintain the microbiological stability of nature-inspired cosmetics.

     "Consumers purchasing cosmetic and personal care products are increasingly concerned about the safety of certain preservatives used in these products. Formulators are searching for alternative ingredients that provide self-preservation but also provide the required efficacy against microbial contamination to keep products safe for consumers," commented Rose Durham, global marketing manager for DuPont Tate & Lyle Bio Products. "The sensiva® PA 30 and sensiva® PA 40 antimicrobial stabilizers featuring Zemea® propanediol are two new ingredients that formulators should consider for this use."

     "Many consumers would like to purchase more natural products. However, most are unwilling to give up the performance that they have come to expect from their personal care products. schülke has combined the best of science and nature in the latest additions to our sensiva® line," states Linda Sedlewicz, country manager for schülke inc. "Both sensiva® PA 30 and sensiva® PA 40 were designed with nature in mind and science as our guide to produce products that are both gentle and effective."
