Detailed Description
Polypropylene glycol PPG-400 (CAS No.: 25322-69-4) produced by Haian Guoli Chemical Co., Ltd. is a high-quality nonionic surfactant. You can inquire about purchasing through the company's official website, telephone hotline, or authorized distributors. Due to factors such as raw material price fluctuations, order quantity, and transportation costs in the chemical raw material market, the prices displayed on the product page are for reference only and cannot be considered as final transaction prices. We strongly recommend contacting Guoli Chemical's sales team directly to obtain the latest quotation and technical support tailored to your needs.
Polypropylene glycol PPG-400 is available in various packaging specifications to meet the needs of different scale customers, including 50 kg plastic drums, 200 kg plastic drums, and IBC totes. For new customers or small batch trials, a minimum order of a single 50 kg drum is typically supported. If you have large-scale production needs, you can negotiate tote or full truckload procurement options to enjoy better bulk discounts. Please confirm the specific packaging form you require when placing an order so that we can arrange production and logistics for you.
Before contacting the sales team, it is recommended that you prepare the following information for more efficient service: basic company information, estimated annual usage, target application areas (such as polyurethane synthesis, lubricants, cosmetics, etc.), and special requirements for technical parameters (such as hydroxyl value, viscosity, moisture content, etc.). Our technical engineers can also provide targeted application suggestions and sample testing support based on your specific formulation.

Application Recommendations
Polypropylene glycol PPG-400 has a wide range of applications. After purchase, please refer to the following recommended dosages based on your specific field:
- Polyurethane Industry: As a soft segment component, it is recommended to add it proportionally to the polyol component based on the required flexibility and hardness. During formulation design, pay attention to its hydroxyl value (260~300) to accurately calculate the amount of isocyanate needed.
- Lubricants and Functional Fluids: As a base oil or co-solvent, the recommended addition amount is 10%~50%. Its excellent lubricity and thermal stability make it suitable for high-temperature environments, but attention should be paid to viscosity adjustment.
- Daily Chemicals and Cosmetics: As a moisturizer and lubricant, the recommended addition amount is 1%~5%. The product is non-irritating and non-sensitizing to the skin, and can be safely used in creams and facial cleansers. However, due to its low HLB value (approx. 2.0), it may need to be compounded with emulsifiers in water-containing formulations.
- Pharmaceutical Applications: As a suppository or ointment base, prescription screening is required based on specific formulation requirements. The product meets relevant safety requirements but still needs end-use validation.
Important Notes
- Minimum Order Quantity: The standard minimum order is 50 kg/drum, and sample testing is supported (please consult sales for specific policies). IBC totes (approx. 1000 kg) are suitable for large-scale procurement with better cost efficiency.
- Packaging and Storage: After receiving the goods, store them in a cool, ventilated, and dry place. The recommended storage temperature is 0~40°C, and keep the container tightly sealed to prevent moisture absorption. Under original sealed conditions, the shelf life is no less than 12 months.
- Safe Handling: Although this product has low toxicity and is non-irritating, it is recommended to wear safety goggles and protective gloves during operation to avoid prolonged skin contact. In case of accidental eye contact, rinse immediately with plenty of water and seek medical attention.
