Cosphaderm® Pentiol natural (INCI: Pentylene Glycol) is a 100% plant-derived, high-purity 1,2-alkanediol. Sourced from sustainable sugar cane or corn, it is one of the most versatile and widely used multifunctional glycols in green chemistry. This clear, odorless liquid serves as a high-performance humectant, solvent, and antimicrobial booster, offering a superior sensory profile and more robust protection than shorter-chain alternatives like Propanediol.
Key Benefits and Performance
-
Superior Sensory & Hydration: As a C5 diol, it provides intensive moisturizing and skin-conditioning benefits. It is famously valued for its “weightless” feel, offering a much lighter and less tacky skin-feel than traditional glycerin.
-
Universal pH Independence: Its antimicrobial activity is entirely physical/structural and does not rely on ionization. It remains 100% effective across the entire pH spectrum, providing a fail-safe solution for neutral or high-pH formulations where organic acids are inactive.
-
The “Synergy Specialist”: While it shows good activity against bacteria, its true power lies in its ability to boost other antimicrobials. By destabilizing microbial cell membranes, it allows for a significant reduction in the total concentration of primary preservatives.
-
High-Purity Solvent: It is an excellent carrier and solvent for botanical extracts and difficult-to-dissolve active powders, often improving the clarity of aqueous systems.
Formulation Guidelines
-
The “Chain Length” Advantage: Its antimicrobial potency is significantly higher than Propanediol (C3), though it is generally slightly less hydrophobic than Caprylyl Glycol (C8). This makes it the perfect “middle ground” for balanced solubility and efficacy.
-
Solubility & Incorporation:
-
Addition: Can be incorporated into the water phase, the oil phase, or added during the cool-down stage. It is fully cold-processable
