Cosphaderm® CHA is the Hydroxamic Acid of caprylic acid. The natural organic acid is a chelator and antimicrobial with a strong efficacy against a broad spectrum of microorganisms, especially yeasts and molds. In contrast to other organic acids, Cosphaderm® CHA remains undissociated even at neutral pH and is therefore applicable over a broad pH range up to pH 7.5. The combination of chelating and antimicrobial properties in one molecule allows for use of Cosphaderm CHA for stabilization of cosmetic formulations against metal ion-induced oxidation and protection against microorganisms at the same time.

Cosphaderm® GMCY is a high purity ester of glycerine and caprylic acid with at least 88% monoester content. Produced from natural sources, it is a readily biodegradable ingredient used in cosmetic and food industry applications for its emollient and emulsifying as well as moisturizing, wetting and refatting properties. Cosphaderm GMCY also provides a strong antimicrobial efficacy against bacteria and yeasts over a pH range from 3.5 to 7.5.

Cosphaderm Heptiol natural is a pure and colourless diol with a water-solubility of up to 1%. It is used as a moisturizer and Humectant for both skin care and hair care formulations. Static light scattering experiments have shown that Cosphaderm diols can also be used to stabilize o/w emulsions by droplet size reduction. Another property of 1,2-heptanediol 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® AP is the lipophilic ester of ascorbic acid and palmitic acid. The palmityl ester possesses improved skin penetration and stability properties compared to ascorbic acid. As an established vitamin C derivative it can be used in skin whitening approaches. The main application of ascorbyl palmitate is to act as a radical scavenger and stop oxidative radical chain reactions or even regenerate depleted antioxidants. By this means, Cosphaderm® AP achieves protection of unsaturated fat and oil components on its own or in synergy with other antioxidants like tocopherols or rosemary extract.
