Cosphaderm® Pentiol natural is a pure, transparent, colorless and odorless glycol of natural origin. 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 and hair care formulations. Static light scattering experiments have shown that Cosphaderm® Pentiol natural can also be used to stabilize o/w emulsions by droplet size reduction. Another property of Pentylene Glycol 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® 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® 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® PA-12 is a powder product consisting of the sodium salt of phytic acid, which acts as a strong natural chelating agent and is effective over a wide pH range. Derived from the soak water of corn bran, Cosphaderm® PA-12 is completely natural and COSMOS-approved. Like other chelators, sodium phytate can contribute to preservation strategies by sequestering physiologically important metal ions. Its chelating properties additionally provide antioxidative functionality by preventing the formation of reactive oxygen species while also reducing discoloration of cosmetic products.
