Mono Propylene Glycol USP Grade is used across regulated and performance-critical industries where purity, consistency and impurity control are essential.
| Industry | Primary Function | Why USP Grade Matters | Typical End Uses |
|---|---|---|---|
| Pharmaceutical | Solvent, excipient, stabilizer | Assay ≥ 99.7%, controlled heavy metals, negative EG/DEG, tight distillation range (184–189°C), low acidity | Oral syrups, injectables, topical formulations, veterinary medicines |
| Cosmetics & Personal Care | Humectant, carrier for actives, viscosity modifier | Low color (≤ 10 Hazen), low iron content, high purity, excellent miscibility in water and alcohols | Creams, lotions, serums, shampoos, deodorants, wipes |
| Food & Beverage | Flavor carrier, moisture retention agent, stabilizer | Low acidity, controlled impurities, high purity level, batch consistency | Flavor concentrates, bakery applications, processed foods, beverage premixes |
| Industrial & Technical | Heat transfer component, antifreeze base, resin modifier, solvent | Boiling point ~187°C, flash point 99°C, stable viscosity (~55 mPa·s), strong solvency power | De-icing fluids, hydraulic fluids, polyester resins, specialty chemical blends |
Safety Information:
- Toxicity: Low order of acute toxicity by oral or percutaneous routes.
- Handling & Storage: MPG (USP) should be stored in a dry, cool place, ideally below 40°C, in containers such as stainless steel tanks.
- Flammability: Not classified as flammable but will burn under certain conditions.
- Moisture Sensitivity: Slightly hygroscopic, so exposure to moisture should be minimized to maintain product integrity.
Compliance & Certifications:
- Compliant with USP standards for pharmaceutical-grade propylene glycol.
- Batch Testing: Each batch undergoes rigorous testing to ensure compliance with purity, safety, and quality specifications.
