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.

Cosphaderm LAAS is an aqueous mixture of levulinic acid, p-anisic acid and glycerin. Established as a highly effective combination of natural antimicrobial agents, additional skin conditioning and masking properties are provided by levulinic acid and p-anisic acid. Furthermore, the glycerin content in this preparation helps to support the hydration of the outer layer of the skin. The optimal pH range for Cosphaderm LAAS is between 5.0 and 5.5 to keep antimicrobial activity and solubility in perfect balance. This makes it a perfect choice for formulations at skin pH.

Cosphagard® SA natural is 100% naturally sourced and COSMOS-approved salicylic acid made from natural wintergreen oil by mild fermentation and two-step purification. Salicylic acid has been sourced traditionally from willow trees. Willow bark extract has played a role in traditional herbal medicine in many cultures, and the extract of dried bark is still used as a drug in tea or natural medicine. Salicylic acid is a well-known active and listed Preservative that has been used for its antimicrobial, keratolytic and anti-inflammatory activity in products against acne and dandruff for many years.

Cosphaderm® Hexiol natural is a pure, transparent, colourless and odourless diol 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 Hexiol natural can also be used to stabilize o/w emulsions by droplet size reduction.
