Personal Care Ingredients

Polylysine 25% solution is a natural polymer of L-Lysine, an essential amino acid produced by fermentation of bacteria. It can be used alone or in combination with other preservatives. It is not compatible with anionic surfactants. Effective pH 5-8.

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® Exact is a blend of the preservative Phenoxyethanol with Ethylhexylglycerin. It displays a broad antimicrobial efficacy spectrum against bacteria, yeasts and molds. The clear fluid blend is pH-independent and temperature-stable.

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.
