Cosphaderm® Octiol natural (INCI: Caprylyl Glycol) is a 100% natural, high-purity 1,2-alkanediol. Sourced from sustainable oil palm, it represents a major milestone in green chemistry as the first natural-origin version of this industry-standard multifunctional.
Key Benefits and Performance
-
Universal pH Independence: Its antimicrobial activity is entirely physical and does not rely on the ionization of the molecule. It remains fully effective across the entire cosmetic pH spectrum, making it a vital alternative to organic acids in high-pH or neutral formulations.
-
Membrane-Destabilizing Synergy: As a C8-chain diol, it is a master “booster.” It works by destabilizing microbial cell membranes, significantly increasing the penetration and efficacy of other preservatives. This allows for a drastic reduction in the total concentration of listed preserving agents.
-
Emulsion Stabilization: Beyond its antimicrobial role, it acts as a secondary stabilizer in O/W emulsions. By reducing droplet size during the emulsification process, it creates more robust, finely dispersed, and visually homogenous textures.
-
Multifunctional Sensory Profile: It provides a sophisticated skin-feel, acting as a medium-spreading emollient and humectant that reduces the “tackiness” of high-glycerin systems.
-
Deodorant Efficacy: Due to its targeted activity against odor-causing bacteria, it is a frequent choice for natural deodorant sticks and sprays.
Formulation Guidelines
-
The “Full-Spectrum” Partner: While strong against bacteria, it is best paired with a fungicidal co-active for total protection. The supplier recommends combining it with Cosphaderm® Magnolia Extract 98 or Cosphaderm® pAS Natural. for robust mould and yeast control.
-
Incorporation: Highly versatile—it is oil-soluble and water-dispersible. It can be added to the oil phase, water phase, or introduced during the cool-down stage.
