Cosphaderm® Propanediol natural RSPO/MB is a 100% plant-derived, high-purity 1,3-propanediol. Produced via the fermentation of sustainable palm oil, this colorless and odorless viscous liquid serves as the gold-standard, non-petrochemical alternative to synthetic glycols (like Propylene Glycol). It is completely miscible with water and provides a multifunctional base for green skincare, hair care, and color cosmetics.
Key Benefits and Performance
-
Superior Humectancy: With two hydroxyl groups on a short three-carbon chain, it is a powerful humectant that pulls moisture into the skin and hair, providing long-lasting hydration without the stickiness often associated with glycerin.
-
Preservation Booster: While it possesses mild antimicrobial activity against bacteria and yeasts, its primary strength is as a booster. It helps “open” microbial membranes, allowing primary preservatives to work more efficiently.
-
Excellent Solvent & Carrier: Its high polarity makes it an exceptional solvent for botanical extracts, active powders (like Ferulic Acid or Salicylic Acid), and fragrances, often improving the clarity and stability of the final solution.
-
Enhanced Skin Feel: It functions as a light emollient and skin conditioner, reducing the “tackiness” of high-humectant formulas and leaving a smooth, silky finish on the skin.
-
Hair Care Performance: It improves the manageability and softness of hair, making it a versatile addition to shampoos, conditioners, and leave-in treatments.
Formulation Guidelines
-
The “Chain Length” Factor: Formulators should note that while Propanediol (C3) is an excellent humectant, its antimicrobial potency is lower than longer-chain diols like Pentylene Glycol (C5) or Caprylyl Glycol (C8). It should be used as a support agent rather than a standalone preservation booster.
