natural – by design

Half natural, half nature-identical, sensiva® PA 30 is the perfect protection for your formulation. Like the perfect spirals found in nature, nature-identical materials take inspiration from nature, yet provide the more consistent efficacy of a synthetic material. Nowhere is this consistency of efficacy more important than in the area of antimicrobial stabilization. sensiva® PA 30 combines the antimicrobial activity of nature-identical fragrance ingredients with the boosting and skin care properties of naturally-derived materials for a soft preservative system that is ideal for leave-on, wet-wipe and sensitive applications.

Many naturally occurring substances have antimicrobial properties. These materials tend to be more organism-specific and have color and odor issues that are not found in their synthetically produced counterparts. Their natural growing cycles and other environmental variations can have a significant effect on their activity level. An alternative to natural material use that is finding increasing acceptance is the use of nature-identical substances. These synthetic materials are chemically identical to materials found in nature. However, activity level, color and odor can often be more easily controlled and standardized. The consistency and availability of the materials can also be managed to create a more sustainable formulation. sensiva® PA 30 contains nature-identical phenethyl alcohol, a fragrance component found in many essential oils. This material has been found to have antimicrobial activity similar to the more commonly used traditional preservative phenoxyethanol.

The antimicrobial activity of phenethyl alcohol can be boosted by the addition of other nature-identical materials. In its natural form, our formulation can be found in many fruits, including apples, bananas and citrus fruits. The nature-identical formula contained in sensiva® PA 30 acts as an excellent booster for the antimicrobial properties of phenethyl alcohol and significantly reduces its flowery, rose-like scent (patent pending). The faint scent of sensiva® PA 30 can mask possible unpleasant odors of other ingredients in formulations.

The natural content in sensiva® PA 30 is derived from corn. This well known moisturizer improves the skin feel of formulations while enhancing the efficacy of antimicrobial compounds. The combination of naturally-derived material with nature-identical phenethyl alcohol and other proprietary nature-identical formulations in sensiva® PA 30 can effectively stabilize cosmetic formulations against typical microbiological contamination. This combination of naturally-derived and nature-identical ingredients makes it an excellent choice for nature-inspired cosmetics.

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%. It has been shown to inhibit the growth and multiplication of odor-causing bacteria, making it an excellent choice for deodorant products.

With sensiva® PA 30, schülke has formulated a nature-inspired multifunctional cosmetic additive that is peerless protection for leave-on, wet-wipe, and sensitive applications.
