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.

Cosphagard® Pol is a cost-efficient mixture of Potassium Sorbate and the naturally derived multifunctional sodium levulinate. The blend can be used to replace controversially discussed Preservatives like parabens, MIT, triclosan, formaldehyde separators etc. without losing strong antimicrobial effectiveness against bacteria, yeasts and molds. A further advantage is that this blend is COSMOS-approved and also complies with further international certification labels. It can be used for any cosmetic formulation type except purely oil-based formulations. For full efficiency the pH value of the final product should ideally be 5.5.

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.
