Propylene Glycol 99.5%
SINOBIO
2905320000
99.5% Industrial Grade Propylene Glycol is a versatile aliphatic dihydric alcohol with FDA-compliant food-grade and pharmaceutical-grade certifications, manufactured through advanced catalytic hydrogenation of propylene oxide. Renowned for its hygroscopic properties (absorbing up to 50% of its weight in moisture) and excellent solubility in water and organic solvents (including alcohols, esters, and ketones), this colorless, odorless liquid serves as a critical wetting agent, emulsifier, and humectant across industries. Its low toxicity (LD50 >20g/kg in oral rat tests) and biocompatibility make it ideal for applications requiring strict safety standards, such as food preservation, pharmaceutical formulations, and personal care products. Unlike glycerin, it offers better freeze-thaw stability, making it a preferred choice in cold-chain applications.
Parameter | Value |
Purity | ≥99.5% (GC) |
Appearance | Clear, colorless liquid |
Density @ 25°C | 1.036–1.038 g/cm³ |
Boiling Point | 188.2°C |
Flash Point | 107°C (closed cup) |
pH | 5.0–7.0 |
Solubility | Miscible with water, ethanol |
Viscosity @ 20°C | 42.5 mPa·s |
Water Content | ≤0.2% |
Food-Grade Safety:
Complies with FCC (Food Chemicals Codex) 9th Edition and Halal standards (certified by IFANCA).
Prevents caking in powdered foods like seasonings and dairy products by maintaining optimal moisture levels (3–5% water activity).
Acts as a humectant to maintain moisture in baked goods, extending shelf life by 30–50% compared to untreated products.
Resists microbial growth in low-water formulations due to its low redox potential.
Pharmaceutical Applications:
Enhances drug solubility in liquid formulations (e.g., syrups, injectables) by up to 400% for hydrophobic APIs like ibuprofen.
Serves as a cryoprotectant in cell preservation, maintaining >90% cell viability after 6 months of cryostorage at -80°C.
Non-irritating and non-toxic, meeting USP/NF (United States Pharmacopeia/National Formulary) Monograph <1,551> requirements for residual solvents.
Compatible with common excipients including cellulose derivatives, sugars, and surfactants.
Industrial Performance:
Low volatility (vapor pressure <0.1 mmHg @ 20°C) ensures stability in high-temperature processes up to 150°C.
Anti-freezing properties (freezing point -59°C) make it suitable for deicing solutions and coolant formulations in industrial machinery.
Biodegradable (98% degradation within 28 days per OECD 301B test) and environmentally friendly with no bioaccumulation potential.
Baked Goods: Maintains moisture in bread, cakes, and cookies by forming hydrogen bonds with starch molecules, preventing staleness and textural degradation.
Beverages: Acts as a solvent for flavors and colorants in carbonated drinks, juices, and functional beverages, ensuring uniform dispersion even during long-term storage.
Confectionery: Reduces sugar crystallization in candies and chocolates by interfering with sucrose molecular alignment, maintaining smooth texture for 6–12 months.
Dairy Products: Stabilizes emulsions in ice cream (prevents ice crystal formation) and yogurt (maintains creamy consistency during shelf life).
Oral Medications: Enhances the solubility of hydrophobic active ingredients in suspensions, syrups, and oral gels, improving bioavailability by 20–30%.
Topical Formulations: Used in creams and lotions as a moisturizer and penetration enhancer, increasing skin absorption of actives like vitamin C and retinol by 1.5–2x.
Vaccine Production: Protects antigens during freeze-drying processes, preserving vaccine efficacy for up to 24 months at 2–8°C.
Skincare: Adds long-lasting hydration to creams, serums, and shampoos by forming a protective film that reduces transepidermal water loss (TEWL) by 30%.
Fragrances: Solubilizes essential oils in perfumes and colognes, preventing phase separation and ensuring consistent scent profiles.
Makeup: Prevents drying in lipsticks and mascaras by maintaining optimal moisture balance, extending product usability by 2–3 months.
Textiles: Improves dye penetration by 25% and reduces static in fabric processing through its hygroscopic properties, enhancing color fastness.
Paints & Coatings: Acts as a film-forming agent and anti-freeze additive, preventing cracking in water-based paints during cold weather application.
Agriculture: Enhances the efficacy of pesticides and herbicides through improved wetting of leaf surfaces, reducing runoff by 15–20%.
