PENTYLENE GLYCOL
Also known as: Purolan PD-LO
CAS Number: 5343-92-0
Key Benefits
Multifunctional humectant + mild antimicrobial booster + solvent, improves spreadability
How It Works
1,2-Pentanediol acts as a humectant with intrinsic antimicrobial activity that supports preservation. Its low melting point and good solvency make it effective for dissolving active ingredients.
Why BP Derma Uses It
Pentylene Glycol is a sophisticated multitasker — simultaneously providing humectancy, antimicrobial support, and improved active solubility. It allows us to create preservation systems with lower overall preservative concentrations.
