Cosphaderm® Hexiol is a pure, transparent and colorless glycol. Two vicinal OH-groups and a short carbon chain allow unlimited water-solubility. This property is strongly relevant to its most common cosmetic use as a moisturizer and humectant for both skin care and hair care formulations. Static light scattering experiments have shown that Cosphaderm® Hexiol can also be used to stabilize o/w emulsions by droplet size reduction. Another core property of 1,2-hexanediol is its pH-independent antimicrobial activity. It further shows remarkable synergistic effects in combination with other antimicrobial substances, making it possible to minimize the total amount of combined preserving agents.

Cosphaderm® LA-T palm free is a multifunctional blend of natural levulinic acid and its sodium salt solubilized in water and glycerol. As a liquid and water-soluble product, it is conveniently applicable in all kinds of cosmetic formulations. This combination of a mild organic acid with a classical moisturizer unites skin conditioning and humectant properties.

Cosphaderm® Absolute is an innovative humectant active blend which improves skin barrier function while simultaneously reducing the water activity of cosmetic formulations. With the three established humectants sodium lactate, betaine and propanediol in optimally balanced concentrations, Cosphaderm Absolute ensures excellent skin hydration. Additionally, lowering water activity and thus limiting water availability to microorganisms allows a reduction of the antimicrobials required for preservation. Thus, the natural blend combines skin barrier-enhancing properties with a unique antimicrobial mode of action, offering the possibility of an innovative, alternative preservation strategy that meets market needs and current trends in the cosmetics industry.

Cosphaderm HAP is a cost-efficient, water-soluble multifunctional with strong antimicrobial activity, particularly effective against yeasts and moulds. It offers high pH stability in the range of 3 to 9 and does not affect the sensory or physical properties of the formulation. Thanks to its mild profile and its additional antioxidant properties, it is well-suited for a wide variety of formulations while maintaining effective preservation.
