Polyethylene Glycol (PEG-600) is a colorless, transparent, and odorless polyether compound with high purity (typically ≥99.9%) and excellent water solubility. As a versatile chemical raw material, it features stable viscosity, low toxicity, and strong compatibility with other substances.
Available in food, pharmaceutical, cosmetic, and industrial grades (meeting USP/BP/CP standards), PEG-600 serves as a key excipient in pharmaceutical formulations, humectant in cosmetics (creams/lotions), lubricant in industrial processes, and processing aid in food production. It’s supplied in bulk drums for B2B needs, ideal for manufacturers seeking reliable, multi-functional raw materials.
Product Advantage
Ultra-High Purity with Strict Quality Control
PEG-600 achieves a purity level of ≥99.9%, far exceeding industry average standards. Our production process adopts triple distillation and precision filtration technology, reducing impurities (such as heavy metals and residual monomers) to below 0.001%. Each batch undergoes third-party testing, with test reports provided to customers, ensuring it meets the strict requirements of high-end pharmaceutical and food applications.
Multi-Grade Customization for Diverse Scenarios
We offer 4 specialized grades (pharmaceutical, food, cosmetic, industrial) tailored to different industry needs. Pharmaceutical grade complies with USP/BP/CP standards, suitable for drug excipients; food grade passes FDA certification, safe for food additives; cosmetic grade has a pH value of 6.0-7.5, non-irritating to skin. This customization helps customers avoid "one-size-fits-all" inefficiencies and reduce cost waste.
Exceptional Stability & Compatibility
With a viscosity range of 210-260 cSt (25℃), PEG-600 maintains stable physical properties even in temperature fluctuations (-10℃ to 60℃). It shows strong compatibility with over 90% of common chemicals (such as surfactants, alcohols, and esters) without causing precipitation or discoloration. This stability reduces product failure risks for manufacturers in long-term storage and formulation.
Low Toxicity & Eco-Friendly Characteristics
PEG-600 has an LD50 (oral, rat) of >5000 mg/kg, classified as "practically non-toxic" by the OECD. It is biodegradable, with a degradation rate of over 85% within 28 days in soil or water environments. For customers focused on environmental responsibility and product safety, this feature eliminates concerns about regulatory compliance and end-user health risks.
Reliable Bulk Supply Capacity
Our factory has an annual production capacity of 50,000 tons, supporting bulk orders from 100kg to 1000 tons. We guarantee a lead time of 3-5 working days for standard grades and 7-10 days for customized grades. Equipped with 200L sealed drums and IBC tanks, we ensure zero contamination during transportation, with a on-time delivery rate of 99.5% over the past 3 years.

Product Uses
As a pharmaceutical excipient, PEG-600 is widely used in oral medications (e.g., tablets, syrups) and topical drugs (e.g., ointments). It acts as a solubilizer to improve drug solubility, a lubricant to reduce tablet friction during production, and a stabilizer to extend drug shelf life. Its low toxicity and USP/BP compliance make it safe for medical use.
2. Cosmetics & Personal Care
In cosmetic formulations, PEG-600 functions as a humectant, locking moisture in skin care products like creams, lotions, and serums. It also works as an emulsifier, blending oil and water components in shampoos and conditioners. With a mild, non-irritating formula, it suits sensitive skin products, enhancing user comfort.
3. Industrial Manufacturing
In industrial settings, PEG-600 serves as a lubricant for metal processing and plastic molding, reducing equipment wear. It acts as a plasticizer to improve the flexibility of PVC products and a coalescing agent in water-based coatings, enhancing film formation. Its stable viscosity (210-260 cSt at 25℃) ensures consistent performance in industrial processes.
As a food-grade additive, PEG-600 is used as a processing aid in food production. It acts as a lubricant for food machinery (e.g., bakery equipment) to prevent sticking, and a coating agent for fruits/vegetables to maintain freshness. It meets FDA standards, with no harmful residues, ensuring food safety.
PEG-600 acts as a reaction medium and catalyst carrier in chemical synthesis. Its high compatibility with organic and inorganic compounds makes it ideal for producing surfactants, dyes, and polymer materials. It also helps control reaction temperature, improving the yield and purity of target products.
Product Operate Guide
Wear gloves when taking PEG-600 (liquid form). Use a clean, dry tool (e.g., spoon, pipette) to avoid contamination. Seal the container tightly after use.
Add PEG-600 to other ingredients at room temp (20-25℃). Stir gently until fully dissolved (usually 5-10 mins). Adjust the amount based on your needs (e.g., 5-15% in cosmetics).
Store in a cool, dry place away from direct sunlight. Keep it at 5-30℃ to prevent viscosity changes. Use within 2 years of production for best performance.
FAQ
Is PEG-600 safe to use in skin care products?
Yes. Cosmetic-grade PEG-600 has low toxicity and non-irritating properties, complying with global safety standards. It’s widely used in creams and lotions, but avoid direct contact with broken skin.
2. Can different grades of PEG-600 be mixed?
Not recommended. For example, industrial-grade may contain impurities unsuitable for pharmaceuticals/food. Mixing grades could affect product quality and safety, so use the specified grade only.
3. What if PEG-600 becomes cloudy or thickens?
Cloudiness may occur at low temps (below 5℃) – warm it to 20-25℃ gently, and it will recover. If thickening happens with no temp change, check if the container was sealed; discard if contaminated.
4. Does PEG-600 react with other common chemicals?
It has high compatibility with most surfactants, alcohols, and esters. But avoid mixing with strong acids/bases for long periods, as this may reduce its stability and affect performance.
