Propylene glycol is clear, colorless, slightly viscous, water-soluble, hygroscopic, odorless liquid with a low vapour pressure. Produced and used in accordance with modern standards of production and quality control. Unlike many other glycols are non-toxic, is not dangerous even during prolonged inhalation of fumes and does not cause poisoning in case of accidental ingestion. Propylene glycol is allowed in most countries as a food additive E1520.

Application
• in production of unsaturated polyester resins (for building industry and production of vehicles), elastic polyurethanes, alkyd resins
• as a solvent of natural and synthetic substances in the preparation of ointments, pastes, creams, shampoos, etc. in the pharmaceutical and cosmetic industry
• in the food industry (E1520) as a solvent for food additives and humidifier tobacco (due to its hygroscopicity)
