Cosphaderm® TOM RSPO/MB (INCI: Pentylene Glycol, Glyceryl Caprylate, Glyceryl Undecylenate) is a 100% plant-derived, multifunctional liquid blend. Engineered for maximum synergy, this transparent to light yellowish liquid provides a powerful alternative to traditional preservatives. It combines sugarcane-derived Pentylene Glycol with high-purity glyceryl esters to deliver a robust, broad-spectrum defense system that is nearly odorless and exceptionally gentle—making it the gold standard for baby care, oral care, and sensitive skin applications.
Key Benefits and Performance
-
Synergistic Antifungal Power: the inclusion of Glyceryl Undecylenate (derived from castor oil) provides particularly strong antifungal activity. The synergy between the three components far exceeds the efficacy of the individual ingredients used alone.
-
Neutral Sensory Profile: Being nearly odorless and colorless, it does not interfere with the delicate fragrance or aesthetic of high-end cosmetic products, even in water-clear tonics or fragrance-free creams.
-
Broad-Spectrum Protection: Extensive challenge testing demonstrates its efficiency as a standalone alternative to listed preservatives across almost all formulation types.
-
Multifunctional Skin Benefits: Beyond its antimicrobial role, the blend acts as a high-performance humectant and emollient, improving skin hydration and leaving a soft, non-tacky finish.
Formulation Guidelines
-
Solubility & Incorporation:
-
Water Phase: Water-dispersible (forms a turbid/cloudy solution).
-
Oil/Alcohol Phase: Fully soluble in oils, alcohols, and diols.
-
Addition: Can be incorporated into the water or oil phase, or added during the final “cool-down” stage.
-
-
Thermal Constraints: Avoid prolonged heating at high temperatures (limit exposure to less than 30 minutes) to prevent the degradation of the glyceryl esters.
