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.
