Propylene Glycol (PG) Industrial & Food Grade is a safe low-toxicity polyol with diversified high-value downstream applications, and Linkwin operates separated production and purification lines for industrial grade and food-pharma grade PG, implementing stricter heavy metal and aldehyde control for high-end edible/medicinal grade to comply with FCC, USP international auxiliary material specifications, while industrial grade focuses on purity stability for coolant and solvent formulation. PG is colorless transparent viscous liquid fully miscible with water, ethanol and most organic solvents, possessing triple advantages of strong solvency, long-lasting humectant performance and low freezing point, with far lower acute toxicity than ethylene glycol, becoming preferred safe alternative for consumer and food-contact formulations globally. High aldehyde impurities will cause peculiar smell and discoloration in cosmetics and oral preparations, so our deep refining process eliminates such defects fundamentally for high-end buyers.

In cosmetic & personal care industry, PG is classic humectant, solvent and penetration booster for facial toner, cream, lotion, essence, shampoo and body wash, improving formula moisturizing performance and active ingredient solubility. Food & pharmaceutical field: food-grade PG acts as carrier solvent for food flavors, preservative solubilizer, anti-freeze agent for frozen food and humectant for baked goods; USP grade serves as solvent, co-solvent and vehicle for oral syrup, topical ointment, capsule excipient and injection auxiliary materials. Industrial application: non-toxic antifreeze for food processing equipment refrigeration system, closed-loop heat transfer fluid, humectant & coalescing agent for water-based coatings and printing inks, solvent for pesticide formulations. Many overseas cosmetic and food manufacturers often complain about peculiar smell, discoloration and excessive aldehyde from inferior PG suppliers; our rigorous purification and sealed anti-oxidation packaging completely solve these quality complaints, protecting your finished product brand compliance and market reputation.
