Polyethylene Glycol 3000 (PEG-3000) is a high-purity, water-soluble polymer with stable chemical properties. Available in powder or granule form, it meets multiple industry standards (USP, food-grade, industrial-grade) for diverse applications.
In pharmaceuticals, it acts as a safe excipient for formulations like laxatives and drug carriers. For cosmetics/personal care, it enhances moisture retention and texture in creams/lotions. Industrially, it’s ideal for lubricants, coatings, and adhesives due to its low impurity and consistent viscosity.
We offer bulk supply with customizable packaging, ensuring reliability for pharmaceutical, cosmetic, and industrial clients globally.
Product Advantage
1. Ultra-High Purity with Low Impurity Content
PEG-3000 achieves 99.8% minimum purity (tested via HPLC), with impurity levels below 0.2%—far lower than industry averages (typically 0.5-1%). This ultra-pure formulation ensures safety for pharmaceutical excipient use (e.g., oral laxatives) and avoids skin irritation in cosmetic applications. Our advanced distillation process removes residual monomers and heavy metals (lead, arsenic < 0.1 ppm), meeting strict USP/NF and EP standards.
2. Stable Viscosity & Consistent Molecular Weight
With a narrow molecular weight distribution (MWD: 2800-3200, controlled via GPC analysis), our PEG-3000 maintains stable viscosity (400-600 cSt at 40°C) across batches. This consistency eliminates production fluctuations for clients in lubricant or coating industries, reducing rework rates by up to 30%. Unlike low-quality PEGs, it resists thermal degradation at temperatures up to 120°C, ensuring long shelf life (24 months in sealed packaging).
3. Customizable Packaging & Bulk Supply Capacity
We offer flexible packaging options (1kg/5kg/25kg HDPE drums, 1000kg FIBC bags) to match client needs, from small-scale R&D to large industrial production. Our factory has a monthly production capacity of 500 tons, enabling 72-hour lead time for bulk orders—30% faster than competitors. All packaging is food-grade/pharmaceutical-grade certified, with moisture barrier liners to prevent clumping.
4. Multi-Grade Certification for Diverse Applications
Our PEG-3000 covers three core grades, each certified for specific uses:
Pharmaceutical Grade: Compliant with USP 43-NF 38, EP 10.0, and FDA DMF (No. 035621), suitable for drug formulations (tablet binders, parenteral solutions).
Food Grade: Meets FDA 21 CFR §172.820 and EU Regulation (EC) No. 1333/2008, safe for dietary supplements and food additives.
Industrial Grade: Passes ISO 9001:2015, ideal for adhesives, plasticizers, and textile auxiliaries.
5. Eco-Friendly Production & Sustainable Sourcing
We use 100% renewable electricity in our manufacturing process, reducing carbon emissions by 25% compared to traditional production. Raw materials are sourced from ISO 14001-certified suppliers, ensuring traceability (batch records retained for 5 years). Our PEG-3000 is fully biodegradable (90% degradation in 28 days via OECD 301B test), aligning with global sustainability goals for green chemistry.

Product Uses
1. Pharmaceutical Industry
As a pharmaceutical-grade excipient, PEG-3000 is widely used in oral medications like laxatives, where it softens stools by retaining water. It also acts as a binder in tablet formulations, improving pill stability and dissolution rates. Additionally, it's applied in topical ointments to enhance drug solubility and skin absorption, complying with USP and EP standards.
2. Cosmetics & Personal Care
In cosmetics, PEG-3000 functions as a humectant and emulsifier. It's added to creams, lotions, and serums to lock in moisture, leaving skin hydrated. In shampoos and body washes, it boosts product texture and helps active ingredients spread evenly, while its low irritation property makes it suitable for sensitive skin products.
3. Food & Dietary Supplements
Food-grade PEG-3000 serves as a glazing agent in confectionery (e.g., candies, chocolates) to add a smooth finish. It's also used in dietary supplement capsules as a plasticizer, ensuring capsule flexibility and preventing brittleness. It meets FDA and EU food safety regulations, making it safe for oral consumption.
4. Industrial Manufacturing
In industrial settings, PEG-3000 is an ideal additive in lubricants, reducing friction between mechanical parts due to its stable viscosity. It's used in coatings to improve film formation and adhesion on surfaces like metal and plastic. Additionally, it acts as a plasticizer in adhesives, enhancing bond strength and flexibility.
5. Chemical Synthesis
As a solvent and reaction medium in chemical synthesis, PEG-3000 dissolves both polar and non-polar compounds, facilitating reactions in industries like fine chemicals and agrochemicals. It also serves as a phase-transfer catalyst, accelerating reaction rates and improving product yields, thanks to its high solubility and compatibility.
Product Operate Guide
Opening & Handling: Use clean gloves when opening packaging to avoid contamination. For powder/granule forms, pour gently to prevent dust; use a dry spoon for small quantities.
Dissolution: Mix with room-temperature water (1:5 ratio recommended) or compatible solvents (e.g., ethanol for cosmetics). Stir slowly until fully dissolved—avoid high heat to preserve stability.
Application: For pharmaceuticals, follow formulation ratios (typically 5-15% by weight). For cosmetics, add to creams during the cooling phase (below 50°C) to maintain texture.
Storage: Seal unused PEG-3000 in original packaging, store in a cool (15-25°C), dry place. Avoid direct sunlight or moisture to prevent clumping; use within 24 months of opening.
FAQ
Q1: Is PEG-3000 safe for human use in pharmaceuticals and cosmetics?
Yes. Pharmaceutical-grade PEG-3000 meets USP/EP standards, with low impurities, and is safe for oral meds or topical ointments. Cosmetic-grade variants have low irritation, suitable for sensitive skin. Both comply with global safety regulations (FDA, EU).
Q2: Can PEG-3000 be replaced with other PEG grades (e.g., PEG-4000) in applications?
It depends. PEG-3000 has a narrower molecular weight (2800-3200) than PEG-4000. For laxatives or lubricants, swapping may alter viscosity/effectiveness. Always test compatibility first, or consult our team for grade recommendations.
Q3: What happens if PEG-3000 clumps during storage? Is it still usable?
Clumping usually occurs from moisture. Break clumps gently, then dry at 40-50°C (no direct heat) for 1-2 hours. If it dissolves fully in water without residues, it’s still usable. To prevent clumping, seal packaging tightly after use.
Q4: Does PEG-3000 react with other common ingredients (e.g., acids, alcohols)?
PEG-3000 is chemically stable with most ingredients. It’s compatible with water, ethanol, and mild acids/bases (pH 4-8). Avoid strong oxidizers (e.g., chlorine) or high temperatures (>120°C), as these may degrade its structure.
Q5: What's the difference between food-grade and pharmaceutical-grade PEG-3000?
Pharmaceutical-grade has stricter impurity limits (e.g., heavy metals <0.1 ppm) and meets USP/EP standards for drug use. Food-grade complies with FDA 21 CFR §172.820, suitable for food additives but not for injectable or oral meds.
