Polypropylene glycol (PPG) is a non-ionic surfactant synthesized via the catalytic polymerization of propylene oxide. It serves as a key polyether backbone in industrial formulations, characterized by its hydrophobic nature and thermal stability. The general molecular formula is (C3H6O)n, with CAS No. 25322-69-4.
Not intended for direct human consumption or parenteral use. Store in tightly sealed containers away from moisture to prevent viscosity changes. Handle with standard PPE to avoid skin irritation during prolonged exposure.
