Key Benefits
Humectant and solvent, enhances product stability and preservative efficacy
How It Works
1,2-Propanediol. Acts as both humectant and solvent with mild antimicrobial boosting properties. Enhances preservative efficacy and serves as an excellent solvent for organic UV filters. Lower skin irritation potential than ethanol.
Why BP Derma Uses It
USP-grade Propylene Glycol serves as both a humectant and an active solvent in formulations where we need to dissolve specific ingredients that are not soluble in water alone.
