丙二醇 High Purity Propylene Glycol (PG) 医药级/化妆品级/工业级 高效保湿溶剂原料

Propylene Glycol (PG, CAS 57-55-6) is a premium, high-purity, colorless, and practically odorless viscous clear liquid featuring mild sweet taste and excellent hygroscopic properties. It is completely miscible in all proportions with water, ethanol, acetone, chloroform, and major mainstream organic solvents. As a highly efficient and safe polyol derivative, our USP/Cosmetic grade Propylene Glycol stands out as a critical humectant, viscosity modifier, anti-freezing agent, and flavor carrier across personal care, cosmetics, and skin treatments. Concurrently, in industrial chemical manufacturing, it serves as an indispensable reactive chemical intermediate for synthesizing premium unsaturated polyester resins (UPR), polyurethane bases, and eco-friendly heat-transfer formulations.

Technical Specifications & Physical Properties

Core Applications

• High-End Cosmetics & Personal Care: Extensively formulated as a primary humectant, texture enhancer, and co-solvent in skincare creams, body lotions, toothpastes, and hair cares to optimize moisture-retention and actives penetration.

• Pharmaceuticals & Fragrances: Functions as a safe, compliant liquid vehicle and carrier solvent for topical ointments, oral solutions, and vitamin injections; also deployed as an efficient diluent for food-grade flavor concentrates.

• Resins & Industrial Polymers: Industrial grade PG is heavily consumed to synthesize unsaturated polyester resins (UPR) to enhance downstream fiberglass toughness and hydrolysis resistance, and serves as an intermediate for polyurethanes (PU).

• Green Heat-Transfer & Antifreeze Fluids: Extensively utilized in non-toxic cooling fluids, brewery refrigeration systems, HVAC heat-transfer media, and eco-friendly automotive antifreezes due to its safe, zero-hazard profile.

Packaging & Storage

• Packing: Customarily supplied in standard 215 KGS net weight HDPE plastic or iron drums. Wholesale international trade supports 1000 KGS IBC containers or massive bulk ISO TANK logistics for prompt delivery.

• Storage: Classified as a non-hazardous chemical but is highly hygroscopic. Store within a completely dry, cool, and well-aerated dedicated warehouse away from moisture or rain. Keep all closures airtight and store strictly isolated from powerful oxidizers and acids.
