Polypropylene Glycol PPG-8000 is a high-molecular-weight, colorless, and low-toxicity polymer with excellent thermal stability and solubility. It features high viscosity and good compatibility with various organic materials, making it versatile across industries.
In industrial use, it acts as a lubricant additive, coating plasticizer, and adhesive modifier to enhance product performance. For cosmetics and personal care, it functions as a moisturizer and emulsifier in skincare/haircare formulas. It also meets food and pharmaceutical standards for safe use as a processing auxiliary. Available in bulk or customized packaging, it suits large-scale industrial orders and small-batch formulation needs.
Product Advantage
1. Ultra-High Purity with Strict Quality Control
PPG-8000 achieves a purity level of ≥99.5%, verified by third-party lab testing (ISO 17025 accredited). We eliminate impurities like residual monomers (<0.1%) and heavy metals (<5ppm) through a 3-stage distillation process, ensuring it meets food (FDA 21 CFR §172.820) and pharmaceutical (USP/NF) standards. This high purity prevents formulation contamination, making it safe for sensitive applications like oral care and medical device lubrication.
2. Excellent Thermal & Chemical Stability
With a thermal decomposition temperature of ≥220°C and a pH range of 6.0-8.0 (5% aqueous solution), PPG-8000 maintains stable performance in extreme conditions. It resists oxidation, hydrolysis, and degradation even when exposed to high temperatures or acidic/alkaline environments—critical for industrial processes like high-temperature coating curing or lubricant use in engine systems. Long-term storage tests (12 months at 25°C) show no viscosity change (>±2%), ensuring consistent batch-to-batch quality.
3. Superior Compatibility & Formulation Versatility
PPG-8000 exhibits strong compatibility with over 90% of common organic solvents (e.g., ethanol, mineral oil, ethylene glycol) and polymers (e.g., PVC, polyurethane, acrylics). Its high molecular weight (7,500-8,500 g/mol) enables it to act as both a plasticizer (reducing polymer brittleness by 30-40%) and a thickener (increasing liquid viscosity by 200-300% at 5% addition), eliminating the need for multiple additives in formulations.
4. Low Toxicity & Environmental Friendliness
Classified as "practically non-toxic" (LD50 >5,000 mg/kg in oral rat testing), PPG-8000 poses minimal health risks for handlers. It is also readily biodegradable (60-70% biodegradation within 28 days per OECD 301B test) and free from volatile organic compounds (VOCs <1g/L), aligning with global environmental regulations like EU REACH and US EPA guidelines. This makes it a sustainable alternative to toxic industrial additives, reducing environmental impact for eco-conscious brands.
5. Customizable Packaging & Bulk Supply Capacity
We offer flexible packaging options (1L bottles, 20L drums, 1,000L IBC tanks) to meet small-batch formulation needs (minimum order 1kg) and large-scale industrial demands (monthly supply capacity up to 500 tons). Each package includes a batch-specific COA (Certificate of Analysis) and tamper-proof seals to ensure traceability. Our 72-hour order processing and global logistics network (covering 80+ countries) guarantee fast delivery, with 95% of orders arriving within 5-7 business days.

Product Uses
1. Industrial Lubricants & Metalworking
In industrial lubrication, PPG-8000 acts as a high-temperature lubricant additive. It reduces friction between metal parts by 25-30% and resists degradation at 180-200°C, ideal for engine oils and metal-cutting fluids. Its compatibility with mineral oils also ensures stable blending without sedimentation.
2. Cosmetics & Personal Care
For skincare and haircare, it works as a moisturizer and emulsifier. It locks in skin moisture for 8-10 hours and helps mix oil-based and water-based ingredients (e.g., in lotions, shampoos). Being low-irritant (<0.5% skin irritation rate), it suits sensitive skin products.
3. Food Processing Auxiliaries
As a food-grade additive, PPG-8000 is used in food packaging coatings. It forms a protective layer that prevents oil and water leakage from packages (e.g., snack bags) and meets FDA standards, ensuring no harmful substances migrate into food.
4. Polymer & Plastic Industry
In polymer production, it functions as a plasticizer for PVC and polyurethane. It increases plastic flexibility by 30-40% and improves impact resistance, making it suitable for flexible pipes, wire insulation, and plastic films. It also enhances the processability of polymers during extrusion.
5. Pharmaceutical Auxiliaries
For pharmaceuticals, it serves as a solubilizer in oral liquids and topical creams. It improves the solubility of poorly water-soluble drugs by 15-20%, boosting drug absorption. Its USP certification also ensures safety for medical use, such as in cough syrups and skin ointments.
Product Operate Guide
Pre-Use Prep: Store in a cool (15-25°C), dry area away from direct sunlight. Seal the container tightly after each use to avoid moisture absorption.
Blending: For formulations, heat PPG-8000 to 40-50°C (if high viscosity) for easier mixing. Stir slowly into base materials (e.g., oils, polymers) until fully dissolved—no special equipment needed.
Safety Tip: Wear gloves during handling; rinse with water if it contacts skin/eyes. Refer to the COA for recommended dosage (typically 1-10% of total formulation) based on your application.
FAQ
Q: What's the difference between PPG-8000 and lower-molecular-weight PPGs (e.g., PPG-400)?
A: PPG-8000 has much higher viscosity (10,000-15,000 cSt at 25°C) and molecular weight, making it better for thickening/lubrication. Lower PPGs are thinner, often used as solvents or humectants.
Q: Can PPG-8000 be mixed with water?
A: It has limited water solubility (≤5% at 25°C). For water-based formulations, pre-blend with a small amount of ethanol or glycerin first to improve dispersion before adding to water.
Q: What's the shelf life of PPG-8000?
A: When stored properly (sealed, cool, dry), it has a shelf life of 24 months from the manufacture date. After opening, use within 6 months to avoid moisture contamination.
Q: Is PPG-8000 safe for use in children's cosmetics?
A: Yes. It meets EU CosIng and FDA standards, with low irritation (skin sensitization rate <0.1%). Ensure dosage stays within 1-5% (per cosmetic safety guidelines) for children's products.
