- Cosmetics and Pharmaceuticals: Found in skin creams, lotions, and medicines to improve texture and stability.
- Antifreeze: Used in low-toxicity antifreeze and deicing solutions.
- Applications industrielles: Used in hydraulic systems, as a solvent, and in the production of plastics.
Propylene glycol is generally considered safe in small quantities, but should be handled according to guidelines in industrial settings.
