With Cosphaderm® Octiol natural and Cosphaderm® Heptiol natural there are two new natural diols that convince with their strong antimicrobial efficacy. The two COSMOS- and NATRUE-approved multifunctionals offer a wide range of applications in skin and hair care thanks to their pH independence.
Cosphaderm® Heptiol natural is a pure, colourless diol with an attractive, newly listed 1,2-heptanediol INCI. It offers a remarkable clear solubility of up to 1% in water and is excellent for use as a humectant and moisturiser in almost all types of formulations. Due to its chemical structure, built up from an alkyl chain with seven carbon atoms, the diol is liquid at room temperature. This means that there is no need for melting, which makes for easy and fast processing. In addition, Cosphaderm® Heptiol natural offers strong antimicrobial activity against a broad spectrum of relevant microorganisms even at low application concentrations of 0.8 – 1.0 %. The product offers any number of combination possibilities with other raw materials. Remarkable synergistic effects result from combinations with other antimicrobial multifunctional agents.
Cosphaderm® Octiol natural consists of natural caprylyl glycol, which is extracted from the oil palm. The medium-chain diol is soluble in water up to 0.5% and has moisturising and skin-caring properties. Cosphaderm® Octiol natural is the most antimicrobial water-soluble diol in the Cosphatec product portfolio. With an even lower application concentration of 0.3 to 0.5 %, it produces highly efficient strong antimicrobial protection against bacteria, yeasts and moulds. At the same time, it thus offers the possibility of minimising the total amount of combined preservatives.
The synthetic diols can be optimally replaced by the natural diols. The challenge tests show that there is no significant difference in effectiveness against bacteria, yeasts and moulds.

In addition, both natural diols can be used to stabilise O/W emulsions by reducing the droplet size. Like the other diols in the Cosphaderm® range, the two new additions can be combined with other raw materials as desired. For example, to increase efficacy against moulds, Cosphaderm® Heptiol natural can be mixed with Cosphaderm® pAS natural.
