Cosphaderm® Propanediol natural Palm Free is a 100% plant-derived, high-purity 1,3-propanediol. Produced via the fermentation of corn, this clear, colorless, and virtually odorless liquid is the ultimate solution for brands committed to both petrochemical-free and palm oil-free formulations. It serves as a high-performance humectant, solvent, and viscosity modifier, offering a sustainable and sophisticated sensory profile for premium natural cosmetics.
Key Benefits and Performance
-
100% Palm-Free & Corn-Derived: Specifically engineered to bypass the palm oil supply chain, sourcing its carbon entirely from corn fermentation. This allows for “Palm-Free” labeling without sacrificing the performance of a high-purity glycol.
-
Non-Sticky Humectancy: It provides excellent moisture-binding properties comparable to glycerol but with a significantly lighter, non-sticky after-feel. This makes it ideal for high-concentration humectant serums and light face creams.
-
Universal pH Independence: Its mild antimicrobial activity remains constant across the entire pH spectrum.
-
Preservation Booster: As a short-chain (C3) diol, it acts as a “penetration enhancer” for microbial membranes. While not a standalone preservative, it significantly increases the efficacy of more potent antimicrobials, allowing for lower total preservative levels.
-
Versatile Solvent & Solubilizer: Its polar character makes it an exceptional carrier for botanical extracts and a solubilizer for active powders, ensuring a homogeneous and stable distribution in the water phase.
Formulation Guidelines
-
The “Synergy” Strategy: To achieve full broad-spectrum protection (ISO 11930), it should be paired with more potent chain-length diols or extracts. The supplier recommends combinations with Cosphaderm® Pentiol Natural, Cosphaderm® Octiol, or Cosphaderm® Magnolia Extract 98
