Polyethylene Glycol (PEG)-1000 is a polymer with the formula HO(CH₂CH₂O)ₙH, where n gives it an average molecular weight of 1,000. It appears as a white, waxy solid at room temperature. With good water solubility and miscibility with many organic solvents, it shows excellent lubricity, moisture retention, dispersibility, adhesiveness, and antistatic properties.
In the pharmaceutical industry, PEG-1000 serves as a solvent, solubilizer, and emulsifier. It is also used in cosmetics for its moisturizing and lubricating effects. Additionally, it finds applications in textile, rubber, and paint industries, acting as a softener, dispersant, and more.
Product Advantage
1. Exceptional Purity with Strict Quality Control
PEG - 1000 boasts an industry - leading purity level of over 99.5%, achieved through our advanced molecular distillation technology. We conduct 12 rigorous quality inspections throughout the production process, from raw material selection to final packaging. This high purity ensures it is safe for use in pharmaceutical and cosmetic applications, meeting the strict standards of the FDA and EU ECOCERT. Unlike ordinary PEG products with purity below 98%, our PEG - 1000 avoids impurities that may cause irritation or affect product stability.
2. Excellent Solubility and Compatibility
With a unique molecular structure, PEG - 1000 exhibits outstanding solubility in water (soluble at any ratio at 25°C) and miscibility with more than 30 common organic solvents, such as ethanol and propylene glycol. This superior solubility allows it to be easily integrated into various formulations without causing phase separation. In contrast, similar products often have limited solubility, requiring additional surfactants to improve compatibility.
3. Stable Physical and Chemical Properties
Our PEG - 1000 maintains excellent stability over a wide temperature range (-20°C to 80°C) and pH range (3.0 to 11.0). It has a low coefficient of thermal expansion (less than 0.0015/°C) and does not decompose or oxidize easily under normal storage and usage conditions. Accelerated aging tests show that its key performance indicators, such as molecular weight and moisture content, remain unchanged after 12 months of storage. This stability ensures consistent product performance in long - term applications.
4. Customizable Molecular Weight Distribution
Leveraging advanced polymerization control technology, we can adjust the molecular weight distribution of PEG - 1000 to meet specific customer needs. The default molecular weight range is 950 - 1050, with a narrow distribution index (PDI) of less than 1.1. For special applications, we can provide products with a molecular weight range of 900 - 1100 or a narrower range of 980 - 1020. This customization capability enables our PEG - 1000 to adapt to diverse application scenarios, from pharmaceutical excipients to industrial lubricants.
5. Environmentally Friendly Production Process
Our production process for PEG - 1000 is environmentally friendly, with zero wastewater discharge and low energy consumption. We use renewable energy sources, accounting for 30% of the total energy used in production. The raw materials we select are non - toxic and biodegradable, and the product itself is readily biodegradable in the environment, with a biodegradation rate of over 90% within 28 days according to standard tests. This environmentally friendly feature meets the growing demand for sustainable products in the market.

Product Uses
1. Pharmaceutical Industry
In pharmaceuticals, PEG-1000 acts as a key excipient. It serves as a solvent and solubilizer in oral liquid formulations, enhancing drug solubility and bioavailability. Also, it’s used in suppositories to improve drug release and reduce irritation, meeting FDA standards due to its high purity (over 99.5%).
2. Cosmetics and Personal Care
In cosmetics, it functions as a moisturizer and emollient. Added to lotions, creams, and serums, it locks in skin moisture, leaving skin smooth. Its good compatibility with other ingredients (miscible with 30+ solvents) ensures stable formulations, suitable for sensitive skin products.
3. Textile Industry
In textiles, PEG-1000 works as a softener and antistatic agent. It's applied to fabrics during finishing, reducing fiber friction for a softer touch. At the same time, it minimizes static buildup, keeping fabrics from attracting dust, and maintains effectiveness in a wide temperature range (-20°C to 80°C).
4. Rubber Industry
In rubber production, it acts as a plasticizer and dispersant. It improves rubber flexibility and processability by reducing polymer chain interactions. Also, it helps disperse fillers (like carbon black) evenly, enhancing rubber mechanical properties, with stable performance under pH 3.0-11.0.
5. Paint and Coating Industry
In paints/coatings, it serves as a coalescing agent and flow improver. It promotes film formation by lowering resin Tg, ensuring uniform coatings. Its low thermal expansion (＜0.0015/°C) prevents coating cracking, and it mixes well with organic solvents for stable formulations.
6. Food Industry
In food, it's a safe additive (compliant with food-grade standards). Used as a lubricant in candy and bakery production, it prevents ingredients from sticking to equipment. Also, it acts as a humectant in dried fruits, maintaining texture, with no toxicity due to high purity.
Product Operate Guide
For pharmaceutical/cosmetic use: Melt PEG - 1000 at 40 - 50°C (avoid overheating). Mix with other ingredients at 25 - 30°C, stir gently for 5 - 10 mins until uniform. For textiles/rubber: Dilute with water (1:5 ratio) first, then apply via spraying/dipping, dry at 60 - 70°C. For paints/food: Add directly to formulations, stir at 20 - 25°C until dissolved. Store in a cool, dry place (below 30°C) to maintain stability.
FAQ
Q1: How should I store PEG - 1000?
A: Store PEG - 1000 in a cool, dry place below 30°C. Avoid exposure to direct sunlight and high humidity. This helps maintain its stability and prevents degradation, ensuring it remains suitable for use over an extended period.
Q2: Can I use PEG - 1000 in food products?
A: Yes, PEG - 1000 is compliant with food - grade standards. It can be used as a lubricant in candy and bakery production and as a humectant in dried fruits. Its non - toxicity and high purity make it safe for food applications.
Q3: What's the difference between PEG - 1000 and other PEG products?
A: PEG - 1000 has an average molecular weight of 1000. Compared to lower - molecular - weight PEGs like PEG - 200, it's a solid at room temperature. Higher - molecular - weight PEGs may have different solubility and viscosity. PEG - 1000 offers a balance of properties suitable for many applications such as pharmaceuticals and cosmetics.
Q4: Is PEG - 1000 safe for skin contact?
A: PEG - 1000 is generally considered safe for skin contact. It's widely used in cosmetics for its moisturizing and lubricating effects. Its low irritation potential and good compatibility make it suitable for use in products that come into contact with the skin.
