Polypropylene Glycol PPG-1500 is a high-purity, low-odor polyether compound with stable chemical properties and moderate viscosity. As a versatile industrial and cosmetic ingredient, it excels as a moisturizer, emulsifier, and lubricant.
Widely used across sectors, it enhances texture in skincare/haircare products (cosmetic grade), improves lubricity in industrial lubricants and coatings (industrial grade), and acts as a safe excipient in pharmaceuticals or food processing aids (pharmaceutical/food grade).
Offered with ISO/FDA certifications, it's non-toxic, water-compatible, and available in bulk or customizable packaging, meeting diverse B2B needs for global buyers in manufacturing, cosmetics, and pharmaceuticals.
Product Advantage
1. Ultra-High Purity for Multi-Industry Safety
PPG-1500 achieves 99.8%+ purity through advanced molecular distillation technology, with impurity content below 0.2%. This ultra-high purity meets strict standards for cosmetic, pharmaceutical, and food-grade applications—eliminating risks of skin irritation in skincare products and ensuring compliance with drug excipient requirements. It’s also free of heavy metals (lead, mercury < 0.1 ppm) and volatile organic compounds (VOCs < 5 ppm), making it safe for sensitive scenarios like baby care products and oral pharmaceutical formulations.
2. Exceptional Chemical Stability & Consistent Performance
With a narrow molecular weight distribution (MWD = 1.05–1.10), PPG-1500 maintains stable viscosity (200–250 cSt at 25°C) and pH (6.0–7.5) across a wide temperature range (-20°C to 120°C). Unlike low-grade PPGs, it resists oxidation and hydrolysis even in long-term storage (shelf life up to 24 months) and high-temperature processing, ensuring no degradation in lubricants, coatings, or adhesive formulations. This stability reduces production waste by 15–20% for manufacturers compared to conventional alternatives.
3. Versatile Functionality Across Core Sectors
PPG-1500 serves as a multi-functional ingredient: it acts as a moisturizer (locks in 30% more moisture than glycerin in skincare lotions), an emulsifier (reduces oil-water separation rate by 90% in cosmetics), and a lubricant (lowers friction coefficient by 25% in industrial gear oils). It also works as a plasticizer (improves flexibility of PVC products by 18%) and a solvent (dissolves 95% of common active pharmaceutical ingredients). This versatility cuts costs for buyers who need one ingredient for multiple production steps.
4. Strict Certification & Global Compliance
Our PPG-1500 holds ISO 9001, GMP, and FDA certifications, with compliance to REACH (EU), FDA 21 CFR (US), and GB 2760 (China) standards. Each batch comes with a detailed COA (Certificate of Analysis) that verifies purity, viscosity, and safety indicator. We also conduct 10+ quality tests per batch (including HPLC, GC-MS, and heavy metal detection) to ensure consistency—backed by a 5-year track record of zero quality complaints from 500+ global clients (e.g., cosmetic brands in Europe and pharmaceutical firms in the US).
5. Flexible Bulk Supply & Customized Solutions
We offer bulk supply capacities of 500–50,000 liters per order with lead times as short as 7 days (30% faster than industry averages). For specific needs, we provide customized packaging (20L drums, 1000L IBC tanks, or 20FT flexitanks) and tailored formulations (e.g., low-viscosity versions for spray coatings or fragrance-free variants for sensitive skincare). Our global logistics network covers 80+ countries, with door-to-door delivery and duty-clearance support—reducing import complexity for buyers in Asia, Europe, and the Americas.
6. Eco-Friendly Production & Sustainable Attributes
Our PPG-1500 is manufactured via a green synthesis process that reduces energy consumption by 22% and water waste by 35% compared to traditional production methods. It's non-toxic (LD50 > 5000 mg/kg, acute oral toxicity test) and biodegradable (85% degradation rate in 28 days under aerobic conditions), aligning with global sustainability goals. For brands focused on eco-friendly labeling, this helps meet consumer demand for "clean" ingredients—boosting product marketability by 25% (based on 2024 industry surveys).

Product Uses
1. Cosmetics & Personal Care
Used in lotions, creams, and serums as a moisturizer—locks in skin moisture for 8+ hours without greasiness. Also acts as an emulsifier in foundations and lipsticks, preventing oil-water separation. In haircare (shampoos, conditioners), it reduces frizz by forming a protective film on hair strands, improving smoothness.
2. Industrial Lubricants
Blended into metalworking fluids and gear oils to lower friction between mechanical parts—extends equipment lifespan by 30%+. Its stable viscosity (even at -20°C) ensures consistent lubrication in cold environments, suitable for automotive, machinery, and aerospace industrial use.
3. Pharmaceuticals
Serves as an excipient in oral tablets and liquid medications—enhances drug solubility, helping active ingredients absorb faster. Also used in topical ointments to improve spreadability and skin penetration, ideal for anti-inflammatory and antibiotic formulations (compliant with FDA and GMP standards).
4. Food Processing & Packaging
Acts as a food-grade lubricant for conveyor belts in beverage, bakery, and dairy production—non-toxic and easy to clean, avoiding food contamination. Also used as a plasticizer in food packaging films, improving flexibility to prevent cracking during transportation.
5. Adhesives & Coatings
Added to water-based adhesives to boost bonding strength (increases adhesion by 25% for wood and plastic materials). In architectural and industrial coatings, it enhances film-forming properties, making coatings more resistant to water and UV damage, suitable for walls, metal surfaces, and furniture.
6. Household & Daily Chemicals
In liquid detergents and dish soaps, it acts as a solubilizer—helps mix oil-soluble surfactants with water, improving cleaning efficiency. In air fresheners and candles, it stabilizes fragrances, making scents last longer (extends aroma retention by 40% compared to formulations without PPG-1500).
Product Operate Guide
Cosmetic/Pharmaceutical Use: Mix PPG-1500 (5-15% of total formula) with other ingredients at 40-60°C, stir gently until fully dissolved. Avoid high temperatures (>80°C) to prevent property changes.
Industrial Lubricants/Coatings: Blend 10-30% PPG-1500 into base fluids/coating resins at room temp. Stir for 10-15 mins to ensure uniform dispersion.
Storage: Keep in sealed, cool (15-30°C) dry place, away from direct sunlight. Seal tightly after use to avoid moisture absorption.
Note: Follow safety guidelines; wear gloves if handling large quantities.
