Cosphaderm® GMUD RSPO MB (INCI: Glyceryl Undecylenate) is a 100% plant-derived, multifunctional monoester. Comprising a high-purity mixture of glycerine and undecylenic acid esters (derived from castor oil), it is a powerhouse of natural preservation. It is specifically prized in the industry for its exceptional antifungal performance, offering a robust natural solution for products prone to yeast and mould contamination.
Key Benefits and Performance
-
Targeted Antifungal Specialist: It demonstrates superior activity against yeasts and moulds. It is often the “missing piece” in natural preservation systems that are otherwise strong only against bacteria.
-
Gram-Positive Defense: In addition to its fungicidal properties, it provides strong bacteriostatic activity against Gram-positive bacteria, helping to stabilize the skin’s microbiome.
-
Multifunctional Skin & Hair Care: * Refatting & Emollient: It restores the lipid barrier, leaving skin soft and supple.
Formulation Guidelines
-
The “Gram-Negative” Gap: This ingredient is not active against Gram-negative bacteria. For full-spectrum protection, it must be combined with complementary bactericidal agents such as Cosphaderm® Dicapo natural or Cosphaderm® Heptiol natural.
-
Solubility & Incorporation:
-
Water Phase: Water-dispersible.
-
Oil/Alcohol Phase: Fully soluble in oils, alcohols, and diols.
-
Addition: Can be added to the oil phase, water phase, or introduced during the cool-down stage.
-
-
Thermal Constraints: To prevent hydrolysis of the esters, avoid prolonged heating above the maximum recommended temperature (limit to less than 30 minutes).
