Polypropylene Glycol PPG-3000 (CAS 25322-69-4) is a high-performance, colorless, and low-odor polyether compound with a molecular weight of around 3000. It boasts excellent thermal stability, low volatility, and good compatibility with various organic materials.
Widely used across industries, it acts as a lubricant, moisturizer, emulsifier, or plasticizer in cosmetics, pharmaceuticals, coatings, lubricants, and textile auxiliaries. Available in bulk quantities with customizable packaging, it meets industrial, cosmetic, or food-contact standards, making it a reliable choice for manufacturers and traders globally.
Product Advantage
1. Ultra-High Purity with Strict Quality Control
PPG-3000 achieves a purity level of ≥99.5% , verified by third-party lab testing (ISO 17025 accredited). We control impurities such as water content (≤0.1%) and residual monomers (≤0.05%) through advanced distillation and filtration processes. This high purity ensures no adverse reactions in sensitive applications like pharmaceutical excipients or cosmetic formulations, reducing production risks for customers.
2. Exceptional Thermal & Chemical Stability
With a thermal decomposition temperature of ≥200°C and a flash point of 220°C (ASTM D92 standard), PPG-3000 maintains stable performance in high-temperature processing (e.g., coating curing, polymer extrusion). It also resists hydrolysis and oxidation even in acidic/alkaline environments (pH 4-10), ensuring a shelf life of 24 months under proper storage—30% longer than industry average for similar polyether products.
3. Broad Compatibility with Multi-Industry Materials
PPG-3000 exhibits excellent compatibility with over 90% of organic solvents (e.g., ethanol, ethylene glycol), resins (epoxy, polyurethane), and surfactants. Lab data shows it forms homogeneous mixtures with cosmetic oils (e.g., jojoba oil, mineral oil) at a mixing ratio of 1:10 without phase separation, making it a versatile additive for formulations in cosmetics, lubricants, and adhesives.
4. Customizable Viscosity & Packaging for Flexible Needs
We offer adjustable viscosity ranges (500-800 cSt at 25°C, ASTM D445) to match specific customer requirements—from low-viscosity grades for detergents to high-viscosity options for plasticizers. Packaging is customizable too: 20L HDPE drums, 200L iron drums, or 1000L IBC tanks, with a bulk supply capacity of 500+ metric tons per month to support large-scale production schedules.
5. Compliance with Global Industry Standards
Our PPG-3000 meets multiple international standards: USP/NF (for pharmaceuticals), FDA 21 CFR 172.820 (for food contact), and EC No. 10/2011 (for cosmetics). Each batch comes with a Certificate of Analysis (COA) detailing test results, ensuring customers meet regulatory requirements in markets like the EU, US, and Southeast Asia—saving time on compliance verification.

Product Uses
1. Cosmetics & Personal Care
As a mild moisturizer and emulsifier, PPG-3000 is added to lotions, creams, and hair conditioners. It enhances product spreadability, locks in skin/hair moisture without greasiness, and improves compatibility between oil and water phases—ideal for daily skincare and haircare formulations.
2. Pharmaceuticals
Used as a pharmaceutical excipient, it acts as a lubricant in tablet manufacturing (reducing friction between powder and equipment) and a solubilizer for fat-soluble drugs. Compliant with USP/BP standards, it ensures drug stability and safety for oral or topical pharmaceutical products.
3. Industrial Lubricants
Its low volatility and thermal stability make it a key component in metalworking fluids and industrial gear oils. It reduces wear between mechanical parts, maintains lubricity at high temperatures (up to 180°C), and resists oxidation—extending equipment service life.
4. Coatings & Inks
In water-based coatings and printing inks, PPG-3000 functions as a plasticizer and flow agent. It improves coating flexibility, prevents cracking on substrates (e.g., wood, metal), and enhances ink adhesion—ensuring smooth, durable finished surfaces.
5. Textile Auxiliaries
Added to textile softeners and dyeing auxiliaries, it boosts fabric softness, reduces fiber friction during processing, and helps dyes disperse evenly. It also improves textile water repellency slightly, making fabrics more resistant to mild stains.
Product Operate Guide
Preparation: Store in a cool (15-30°C), dry, well-ventilated area; avoid direct sunlight. Before use, check the CoA to confirm grade matches your application (e.g., cosmetic/pharmaceutical).
Mixing: Add to formulations at 2-10% (adjust per need). Stir gently at 25-40°C for 5-10 mins—its good compatibility ensures easy blending with oils/solvents, no extra emulsifiers needed in most cases.
Safety: Wear gloves when handling; rinse with water if in contact with skin/eyes. Keep away from open flames due to its flash point.
FAQ
Q1: Is PPG-3000 safe for use in cosmetic or food-contact products?
Yes. Our PPG-3000 meets FDA 21 CFR 172.820 (food contact) and EC No. 10/2011 (cosmetics) standards. Each batch has a COA to confirm safety, making it suitable for these sensitive applications.
Q2: What's the difference between PPG-3000 and lower-molecular-weight PPGs (e.g., PPG-1000)?
PPG-3000 has higher viscosity (500-800 cSt at 25°C) and lower volatility than PPG-1000. It's better for long-lasting lubrication or moisturization, while PPG-1000 suits low-viscosity needs like detergents.
Q3: How should I store PPG-3000 to maintain its quality?
Store it in sealed HDPE/iron containers at 15-30°C, away from sunlight and moisture. Unopened, it stays stable for 24 months. Once opened, seal tightly to avoid contamination.
Q4: Can you provide custom viscosity grades of PPG-3000?
Absolutely. We offer customizable viscosity ranges (300-1000 cSt at 25°C) to match your needs. Minimum order quantity for custom grades is 5 metric tons, with a production lead time of 7-10 days.
