ABSTRACT: Public discussion of many traditional preservative chemistries has made it more difficult for formulators to develop adequately preserved products. Inadequately preserved personal care products are a public health risk that can trigger a product recall and severely damage the reputation of the manufacturer. As a result, many formulators are turning to natural and nature-identical multifunctional additives as a way to maintain the microbiological stability and safety of their products. Schülke & Mayr GmbH has a long history of combining chemistries to obtain optimised preservative systems. The boosting effect of naturally-derived Zemea Propanediol, from DuPont Tate & Lyle Bio Products, combined with nature-identical fragrance materials and gentle synthetics, give sensiva PA 30 and sensiva PA 40 the ability to stabilise many personal care formulations to the same stringent criteria as more traditional preservative blends, bridging the gap between tradition and sustainability.
