Cosphaderm® Absolute is a blend of three established humectant actives in optimally aligned concentrations.
Using Cosphaderm® Absolute helps to hydrate the skin and improve the skin’s barrier function while reducing
the water activity of a formulation. The lower the water activity of a formulation, the less antimicrobials
need to be used for preservation.

With sodium lactate and betaine, Cosphaderm® Absolute provides two skin-own substances of the natural
moisturizing factors (NMF), which ensure the maintenance of the moisture content in the skin. In addition to
its solubilizing function, the multifunctional propanediol promotes the moisturizing effect of the blend. The
three substances share a strong hygroscopicity, which lowers the water activity and thus the availability of
water for microorganisms at the recommended use concentrations. Thus, the natural blend combines a safe
antimicrobial mode of action with skin barrier-enhancing properties, providing an innovative, alternative
preservation strategy that meets market needs and current trends of the cosmetics industry.
