Polyethylene Glycol (PEG-8000) is a high-molecular-weight, water-soluble polymer with a white powder/granule appearance. Boasting excellent stability, low toxicity, and good compatibility, it meets industrial, pharmaceutical, food, and cosmetic grade standards (USP/BP, GMP).
Its core functions include acting as a lubricant, binder, and solubilizer in pharmaceuticals (for tablets/capsules); a moisturizer in skincare/haircare; a processing aid in adhesives/coatings; and a safe additive in food. It also enhances solubility in agricultural formulations.
Available in bulk with customizable particle sizes, it suits diverse industrial needs, offering reliable performance for large-scale or specialized applications.
Product Advantage
Exceptional Purity & Consistency: Our PEG-8000 achieves 99.9% purity with minimal impurities (<0.1%), verified by ISO 9001-certified lab testing. Its controlled molecular weight distribution (7,500-8,500 g/mol) ensures stable performance across batches, critical for precise formulations in pharmaceuticals and high-end industrial applications.
Multi-Grade Compliance: Manufactured under GMP standards, our PEG-8000 meets USP, BP, and EP pharmacopoeia requirements. Food-grade variants comply with FDA regulations (21 CFR 172.820), while industrial grades pass strict quality checks, making it versatile for pharmaceuticals，food, cosmetics, and chemical processing.
Enhanced Solubility & Stability: With a hydrophilic structure, it dissolves rapidly in water (solubility ≥95% at 25°C) and maintains stability over a wide pH range (3-10). This properties ensures long shelf life (24+ months when stored properly) and reliable performance in humid or high-temperature environments.
Customizable Form & Packaging: Available in powder, granules, or flakes, with particle size adjustable from 20-200 mesh per client needs. We offer flexible packaging (25kg bags, 500kg supersacks) and can fulfill bulk orders of 100+ tons monthly, supported by our 50,000㎡ production base.
Eco-Friendly Production: Our closed-loop manufacturing process reduces wastewater by 30% compared to industry averages. The product is biodegradable under aerobic conditions (80% degradation in 28 days per OECD standards), aligning with global sustainability goals.

Product Uses
1、Pharmaceutical Industry
Serves as a key excipient in tablets and capsules: acts as a binder to improve powder compressibility, a lubricant to reduce die friction, and a solubilizer to enhance drug dissolution. Complies with USP/BP standards, suitable for oral and topical pharmaceutical formulations.
2、Food Processing
Used as a safe additive (FDA 21 CFR 172.820): acts as a glazing agent for candies/baked goods to boost shine, a moisture retainer for processed meats to prevent drying, and a lubricant in food machinery to reduce wear.
3、Industrial Manufacturing
Applied in adhesives, coatings, and inks: enhances product flexibility and adhesion, reduces viscosity for easier application. Also works as a processing aid in polymer production, improving melt flow and mold release efficiency.
4、Cosmetics & Personal Care
Functions as a moisturizer in skincare (lotions, creams) and haircare (shampoos, conditioners): forms a hydrating film on skin/hair to lock in moisture. Its low irritation makes it suitable for sensitive skin formulations.
5、Agricultural Sector
Added to pesticide/herbicide formulations: improves active ingredient solubility and stability, enhances spray adhesion to crop surfaces, and boosts nutrient absorption, ultimately increasing pest control efficiency.
Product Operate Guide
Storage: Keep in a cool, dry place (15-25°C) sealed in original packaging to avoid moisture absorption. Shelf life is 24 months under proper storage.
Dissolution: For aqueous use, mix PEG-8000 powder/granules with water (stir at 40-50°C if needed) until fully dissolved—no heating required for low-concentration blends.
Dosage: Start with 0.5-5% (by weight) in formulations; adjust based on application (e.g., 2-3% for cosmetics, 1-4% for pharmaceuticals) and test for desired performance.
Safety: Wear gloves when handling; avoid direct eye contact. Rinse with water if skin/eye contact occurs.
FAQ
1、Q: Can PEG-8000 be replaced with other PEG grades (e.g., PEG-6000/PEG-10000) in formulations?
A: It depends on application. PEG-8000's higher molecular weight offers better binding/lubrication than PEG-6000, but PEG-10000 may be too viscous. Test compatibility first for critical uses like pharmaceuticals.
2、Q: Is PEG-8000 safe for direct skin contact in cosmetics?
A: Yes. Cosmetic-grade PEG-8000 has low irritation (meets EU CosIng standards) and forms a gentle hydrating film, making it safe for sensitive skin when used at recommended 2-5% concentrations.
3、Q: What happens if PEG-8000 absorbs moisture during storage?
A: Mild moisture absorption causes slight clumping, but it won't affect performance. Simply break clumps before dissolving; severe moisture may reduce shelf life, so always reseal packaging.
4、Q: Does industrial-grade PEG-8000 meet the same purity standards as pharmaceutical-grade?
A: No. Pharmaceutical-grade has 99.9% purity and meets USP/BP, while industrial-grade (95%+ purity) focuses on cost-effectiveness for non-medical uses—never substitute industrial for pharmaceutical applications.
5、Q: Can you provide PEG-8000 with a specific particle size not listed in standard options?
A: Yes. We offer custom particle sizes (10-300 mesh) based on your needs, with a minimum order quantity of 500kg. Contact our technical team to confirm lead time and specifications.
