Polyethylene Glycol 200 (PEG 200), with CAS No. 25322-68-3, is a clear, colorless, low-viscosity liquid with high solubility in water and most organic solvents. It boasts excellent chemical stability and low volatility, making it versatile across industries.
As a key raw material, its core functions include acting as a solvent, lubricant, and humectant. It’s widely used in pharmaceuticals (as an excipient for formulations), cosmetics (skincare/haircare for moisture retention), food processing (as a safe additive), and industrial fields (paint, ink, adhesives for viscosity adjustment). Available in food, pharma, and industrial grades, it meets global standards like USP and GMP, ensuring reliability for diverse applications.
Product Advantage
Ultra-High Purity for Reliable Performance
PEG 200 achieves a purity level of ≥99.5%, verified by third-party lab testing (with impurity content ≤0.5%). This high purity ensures no unwanted residues interfere with end products—critical for pharmaceutical formulations (preventing drug stability issues) and cosmetic applications (avoiding skin irritation). It also reduces filtration steps in production, cutting clients’ processing costs by 8-12% on average.
Exceptional Chemical Stability & Low Volatility
With a boiling point of 250-260°C and a flash point of ≥180°C, PEG 200 maintains stable properties across a wide temperature range (-20°C to 100°C). It shows no hydrolysis or oxidation under normal storage conditions, with a shelf life of up to 24 months (when sealed in original packaging). This stability eliminates batch-to-batch variations, ensuring consistent quality for long-term production runs.
Superior Solubility & Compatibility
PEG 200 exhibits 100% solubility in water and excellent miscibility with most organic solvents (e.g., ethanol, glycerin, propylene glycol). Its low viscosity (25-35 cSt at 25°C) allows easy blending into formulations, reducing the need for additional thinning agents. For example, in cosmetic lotions, it mixes evenly with oils and active ingredients, improving product texture without compromising moisture-retention efficacy.
Global Compliance with Strict Industry Standards
Our PEG 200 meets international certifications, including USP (United States Pharmacopeia), EP (European Pharmacopoeia), and GMP (Good Manufacturing Practice). Food-grade variants comply with FDA regulations (21 CFR 172.820), while pharma-grade options pass heavy metal tests (lead ≤0.1 ppm, arsenic ≤0.05 ppm). These certifications enable clients to access global markets (e.g., EU, US, Japan) without regulatory barriers.
Flexible Bulk Supply & Customization
We offer bulk packaging from 20L drums to 1000L IBC totes, with a monthly production capacity of 500+ metric tons—ensuring on-time delivery even for large orders (lead time: 3-7 days for stock). Customization options include pH adjustment (3.0-7.0) and low-water variants (moisture ≤0.2%), tailored to specific industrial needs (e.g., high-precision adhesive formulations).
Eco-Friendly & Safe for End-Use
PEG 200 is non-toxic (LD50 >5000 mg/kg in oral rat testing) and biodegradable (80% biodegraded within 28 days under OECD 301B conditions). It contains no VOCs (volatile organic compounds) or hazardous additives, making it safe for eco-conscious applications—such as water-based paints and natural skincare products. This aligns with global sustainability trends, helping clients meet green production goals.

Product Uses
1、Pharmaceutical Industry
As a USP/GMP-compliant excipient, PEG 200 is used in oral liquids, injectables, and topical creams. It acts as a solvent to dissolve active pharmaceutical ingredients (APIs), enhances drug stability, and reduces irritation on mucous membranes. It’s also a key component in laxatives, helping regulate bowel movements safely.
2、Cosmetics & Personal Care
In skincare (moisturizers, serums) and haircare (shampoos, conditioners), PEG 200 works as a humectant—locking in moisture to keep skin hydrated and hair smooth. Its low viscosity improves product spreadability, while its compatibility with oils/actives ensures gentle, non-irritating formulations for sensitive skin.
Food-grade PEG 200 serves as a safe additive: it’s a lubricant for food machinery (preventing sticking during production) and a solvent for food colors/flavors. It also helps maintain texture in baked goods and confectionery, complying with FDA (21 CFR 172.820) and EU food safety standards.
4、Industrial Applications
In paints, inks, and adhesives, PEG 200 adjusts viscosity to optimize flow and drying speed. As a lubricant in metalworking, it reduces friction between tools and materials. It’s also used in textile processing to improve fabric softness and dye absorption, thanks to its high solubility and chemical stability.
As a versatile solvent, PEG 200 blends with surfactants, polymers, and additives in industrial cleaners and detergents. It enhances cleaning efficacy by dissolving grease and dirt, while its low volatility ensures long shelf life for concentrated formulations.
Product Operate Guide
Handling & Storage: Use clean, dry tools to take PEG 200 (avoid contamination). Store in sealed containers at 5-30°C, away from direct sunlight. Seal tightly after use to prevent moisture absorption.
Blending Tips: For formulations (cosmetics/pharma), mix at room temp. It dissolves quickly in water—stir gently for 2-5 mins until uniform. No extra heating needed (prevents property changes).
Safety Note: Wear gloves if using in bulk. Rinse with water if it touches skin/eyes. Follow grade-specific guidelines (e.g., food-grade only for food use).
FAQ
1.Is PEG 200 safe for use in cosmetics and food products?
Yes. Food-grade and cosmetic-grade PEG 200 comply with FDA (21 CFR 172.820) and EU standards. It’s non-toxic, non-irritating for skin, and safe for oral intake in regulated amounts, making it suitable for these applications.
2.How long can PEG 200 be stored, and what are the storage conditions?
When sealed in original containers and stored at 5-30°C away from sunlight and moisture, PEG 200 has a shelf life of up to 24 months. Avoid opening containers unnecessarily to prevent contamination or moisture absorption.
3.Can PEG 200 be replaced with other PEG grades (e.g., PEG 300, PEG 400) in formulations?
It depends on viscosity needs. PEG 200 has lower viscosity than PEG 300/400. For applications requiring low viscosity (e.g., thin serums, quick-dissolve APIs), PEG 200 is better; higher grades suit thicker formulations. Test compatibility first.
4.Do you provide certification documents (e.g., USP, GMP) for PEG 200?
Yes. We offer full certification packages for pharma/food-grade PEG 200, including USP compliance reports, GMP certificates, and third-party purity test results. These are provided free of charge with bulk orders.
5.What's the recommended dosage of PEG 200 in pharmaceutical laxatives?
Typically, 10-30 mL of PEG 200 (diluted in water) is used for adult laxative purposes, but it must follow pharmaceutical formulation guidelines. Always consult a pharmacologist or refer to USP monographs for precise dosing.
