Propylene Glycol

Propylene glycol (PG) is widely utilized across multiple industries in English-speaking contexts due to its solubility, low toxicity, and stability. Key applications include:

1. ‌Industrial Manufacturing & Functional Fluids‌
   Acts as a solvent in antifreezes, de-icing agents, heat transfer fluids, and lubricants, efficiently dissolving additives for optimal performance. It also serves as a solvent in producing resins like unsaturated polyester and polyurethane.
   

2. ‌Pharmaceuticals & Cosmetics‌
   Functions as a solvent and humectant in oral/topical drugs and cosmetics (e.g., moisturizers, serums), enhancing solubility of active ingredients and retaining moisture. It is a key solvent in intravenous medications (e.g., lorazepam, diazepam).
   

3. ‌Food & Chemical Processing‌
   Approved as a food additive (e.g., in sucrose fatty acid ester production), and used as a solvent for fats, oils, waxes, and resins. Its miscibility with water and organic compounds supports formulations in coatings or paints.
