Polypropylene Glycol PPG-200(CAS 25322-69-4): High Solubility & Moisturizing Agent for Daily Chemical Products

Product Advantage

1. Ultra-High Purity with Strict Quality Control
   PPG-200 achieves a purity level of ≥99.5%, verified by third-party lab testing (with test reports available upon request). Our production process adopts a multi-stage distillation and filtration system, which effectively reduces impurities to less than 0.5%. This high purity ensures minimal interference in downstream formulations, making it ideal for sensitive applications like cosmetics and pharmaceuticals, where ingredient purity directly impacts product safety and performance.
2. Exceptional Chemical & Thermal Stability
   With a thermal decomposition temperature of over 200°C and a pH range of 6.0-7.5 (at 25°C), PPG-200 maintains stable properties across a wide range of processing conditions. It resists oxidation and hydrolysis even in long-term storage (shelf life up to 24 months under proper conditions), avoiding viscosity changes or sediment formation. This stability reduces production waste and ensures consistent quality for batch-to-batch manufacturing.
3. Low Toxicity & Broad Regulatory Compliance
   Classified as "low toxicity" (LD50 > 5000 mg/kg in oral rat testing), PPG-200 meets global safety standards, including FDA (21 CFR 172.820) for food contact, EU EC No. 10/2011 for food additives, and ISO 9001:2015 for quality management. It contains no heavy metals (lead, mercury, arsenic < 1 ppm) or harmful solvents, making it safe for use in food processing, pharmaceutical excipients, and personal care products that come into direct contact with skin or mucous membranes.
4. Versatile Solubility & Compatibility
   PPG-200 exhibits excellent solubility in water (soluble at any ratio) and most organic solvents (ethanol, propylene glycol, mineral oils). This versatility allows it to be easily integrated into various formulations—from water-based cosmetic serums to oil-based industrial lubricants—without causing phase separation. It also shows strong compatibility with surfactants, polymers, and active ingredients, enhancing formulation flexibility for manufacturers.
5. Controllable Viscosity & Customizable Grades
   With a standard viscosity of 25-35 cSt (at 25°C), our PPG-200 can be tailored to meet specific customer requirements (viscosity range: 20-40 cSt) through precise molecular weight adjustment. We offer four dedicated grades (industrial, cosmetic, food, pharmaceutical) with customized packaging (20L drums, 200L IBC tanks, 1000L bulk containers) to suit small-batch R&D or large-scale production needs, ensuring efficient supply chain support.

Technical Parameters

Product Uses

1. Cosmetics & Personal Care
   As a mild humectant and emollient, PPG-200 is widely used in lotions, creams, serums, and makeup removers. It locks in moisture to keep skin hydrated, reduces product greasiness, and enhances the spreadability of formulations. It also works as a solvent for active ingredients like vitamins, ensuring even distribution for better skin absorption.
2. Pharmaceutical Industry
   In pharmaceuticals, PPG-200 serves as a safe excipient and solubilizer. It's added to oral liquids (syrups, suspensions) to improve drug solubility and stability, and to topical ointments to enhance texture and skin penetration. It meets strict pharmaceutical-grade standards, ensuring compatibility with sensitive officinal formulations.
3. Food Processing
   Approved as a food additive (FDA 21 CFR 172.820), PPG-200 acts as a humectant and stabilizer in processed foods. It's used in baked goods to retain moisture and extend shelf life, in confectionery to prevent sugar crystallization, and in dairy products to improve texture and consistency.
4. Industrial Lubricants
   In industrial settings, PPG-200 is a key component in water-based and oil-based lubricants. Its low toxicity and good thermal stability make it suitable for lubricating machinery parts, metalworking fluids, and hydraulic oils. It reduces friction, prevents wear, and maintains lubricant performance at varying temperatures.
5. Coatings & Adhesives
   PPG-200 functions as a plasticizer and solvent in coatings (water-based paints, industrial coatings) and adhesives. It improves coating flexibility to prevent cracking, enhances adhesive bond strength, and helps dissolve resins and pigments, ensuring uniform application and smooth film formation.

Product Operate Guide

1. Preparation: Wear gloves during handling. Store PPG-200 in a cool, dry, sealed container away from direct sunlight and heat sources (above 200°C may cause decomposition).

2. Mixing: Add PPG-200 to formulations (e.g., cosmetics, lubricants) at 5%-20% (adjust per needs). Stir slowly at 25-40°C for 5-10 mins until fully dissolved—no phase separation means good integration.

3. Post-Use: Seal the container tightly after use. Clean tools with ethanol or warm water promptly. Check compatibility with other ingredients via small-batch testing first.

FAQ

1. Q: Is PPG-200 safe for use in skin-care products?
   A: Yes. Cosmetic-grade PPG-200 has low toxicity (LD50 > 5000 mg/kg) and meets EU and FDA safety standards. It's mild, non-irritating to most skin types, and widely used in lotions/creams as a humectant.
2. Q: How should I store PPG-200 to maintain its quality?
   A: Store it in a sealed, cool (15-30°C), dry area away from direct sunlight and heat. Avoid contact with strong oxidizers. Properly stored, it has a 24-month shelf life without viscosity or purity changes.
3. Q: Can PPG-200 be mixed with water and other solvents?
   A: Absolutely. It dissolves fully in water (any ratio) and common solvents like ethanol or mineral oils. No phase separation occurs when mixed properly, making it easy to integrate into various formulations.
4. Q: What's the difference between industrial-grade and food-grade PPG-200?
   A: Food-grade PPG-200 has stricter impurity controls (heavy metals < 1 ppm) and meets FDA 21 CFR 172.820 for food contact. Industrial-grade is for lubricants/coatings, not for food/pharmaceutical use.
5. Q: Do you provide samples of PPG-200 for testing?
   A: Yes. We offer 100-500mL samples of all grades (cosmetic, food, pharmaceutical) to help you test compatibility with your formulations. Contact our sales team to request samples.
