Polyethylene Glycol 800 (PEG-800) - Low Toxicity for Cosmetic & Personal Care Products

Product Advantage

1. Ultra-High Purity Meeting Global Standards
   PEG-800 achieves a purity level of ≥99.5%, with impurity content (such as ethylene glycol and diethylene glycol) ≤0.1%, fully complying with USP, EP, and FCC standards. This high purity ensures it is safe for pharmaceutical excipients (e.g., oral suspensions) and food additives, reducing potential health risks for end-users. Our factory conducts 3 rounds of quality testing per batch, with a pass rate of 100% over the past 5 years.
2. Exceptional Thermal & Chemical Stability
   With a melting point range of 28-32°C and a boiling point of ≥250°C, PEG-800 maintains stable physical properties even in extreme temperature environments (-10°C to 80°C). It is resistant to hydrolysis and oxidation, with no obvious viscosity change after 12 months of storage (under sealed, cool conditions). This stability minimizes product deterioration during transportation and use, reducing costs for customers.
3. Excellent Solubility & Compatibility
   PEG-800 is highly soluble in water (solubility ≥99g/100mL at 25°C) and compatible with most organic solvents (ethanol, propylene glycol, etc.) and active ingredients (e.g., vitamins, antibiotics). In cosmetic formulations, it can effectively solubilize oil-soluble ingredients, improving product texture and absorption. In chemical synthesis, it acts as a green solvent, replacing toxic organic solvents and meeting environmental protection requirements.
4. Controlled Viscosity & Consistent Quality
   Our PEG-800 has a narrow viscosity range of 15-20 cSt (at 40°C), with a batch-to-batch variation of ≤3%. This precise control ensures uniform performance in applications such as lubricants (for metal processing) and coatings (to adjust film thickness). We use advanced molecular distillation technology to control molecular weight distribution, with a polydispersity index (PDI) of 1.05-1.10, far lower than the industry average of 1.2.
5. Low Toxicity & Biocompatibility
   PEG-800 has low acute oral toxicity (LD50 >5g/kg in rats) and is non-irritating to skin and mucous membranes (tested by a third-party laboratory). It is biodegradable, with 90% of it decomposed into harmless substances (CO2 and H2O) within 30 days in soil. These properties make it ideal for medical devices (e.g., hydrogel dressings) and personal care products (baby lotions), meeting strict safety regulations.

Technical Parameters

Product Uses

1. Pharmaceutical Industry
   Used as an excipient in oral, topical, and injectable formulations to improve solubility of active ingredients. Acts as a lubricant in tablet manufacturing and a stabilizer in vaccines, ensuring consistent drug delivery.
2. Food Processing
   Functions as a food additive (E1521) for moisture retention in baked goods and as a glazing agent for candies. Enhances texture in dairy products and facilitates uniform mixing of ingredients in processed foods.
3. Cosmetics & Personal Care
   Common in creams, lotions, and serums as a moisturizer and thickener. Improves spreadability in hair conditioners and acts as a solvent for fragrances in perfumes and deodorants.
4. Industrial Applications
   Serves as a lubricant in metalworking fluids and a plasticizer in polymer production. Used in coatings to adjust viscosity and in adhesives to enhance bonding strength on various surfaces.
5. Chemical Synthesis
   Acts as a green solvent in organic reactions, replacing toxic alternatives. Facilitates phase transfer catalysis and is a key component in the production of surfactants and polyurethane foams.

Product Operate Guide

1. For Pharmaceuticals/Food
   Add PEG-800 directly to formulations (e.g., tablet blends, food mixes) at 2-10% (adjust per need). Stir at 30-40°C for 5-10 mins to ensure full dissolution; avoid temperatures over 80°C to prevent degradation.
2. For Cosmetics
   Mix with oils/water-based ingredients at room temp (1-5% dosage). Stir gently until homogeneous—no heating needed. Store blended products in sealed containers away from direct sunlight.
3. For Industrial Use
   Dilute with solvents (if required) at 1:1 ratio first. Add to coatings/lubricants, stir at 25-35°C for 10 mins. Test small batches first to match desired viscosity/performance.

   
   

FAQ

1. Q: What's the difference between PEG-800 and other PEG grades (e.g., PEG-600, PEG-1000)?
   A: The key difference is molecular weight—PEG-800 (MW ~700-900) has a higher viscosity than PEG-600 but lower than PEG-1000. It balances solubility and thickness, suiting mid-range needs like cosmetic moisturizers.
2. Q: How should I store PEG-800 to keep its quality?
   A: Store in a sealed, cool (15-25°C) and dry place, away from direct sunlight. Avoid moisture and high temps (>35°C), as they may cause clumping or slight viscosity changes. Unopened, it has a 2-year shelf life.
3. Q: Is PEG-800 safe for use in baby skincare products?
   A: Yes. It has low toxicity (LD50 >5g/kg) and is non-irritating to sensitive skin (third-party tested). Ensure you use cosmetic-grade PEG-800 and follow a 1-3% dosage for baby products.
4. Q: Can PEG-800 be mixed with alcohol or oil-based ingredients?
   A: Absolutely. It's highly compatible with ethanol, propylene glycol, and most oils. For oil blends, stir gently at room temp; for alcohol mixes, no heating is needed—simple stirring ensures full integration.
