Product Description

Product Description of Polyethylene-polypropylene glycol CAS#9003-11-6

Polyethylene-polypropylene glycol (PPG-PEG), also known as Poloxamer, is a versatile block copolymer surfactant. It consists of a hydrophobic PPO core with hydrophilic PEO chains on both sides. It is commonly used as an emulsifier, dispersant, solubilizer, defoamer and wetting agent in multiple industries. It is widely applied in pharmaceuticals, cosmetics, papermaking and cleaning supplies, including drug delivery systems, contact lens solutions and laxatives. Its solubility, foaming property and wetting performance can be adjusted by modifying the ratio of PEO to PPO.


Product Application of Polyethylene-polypropylene glycol CAS#9003-11-6

Pharmaceuticals: Used as an excipient in oral, topical and injectable medicines. It acts as a solubilizer for sparingly water-soluble drugs, and is also used in laxatives as a stool softener as well as in eye drop preparations. Personal Care: Applied in shampoos, toothpaste, moisturizers and contact lens care solutions as a cleansing and thickening agent. Industrial Uses: Applied as a low-foam detergent and defoamer in paper and fermentation industries, and used as a lubricant in metalworking and rubber vulcanization. Biotechnology: Used in cell culture media to protect cells from shear stress in bioreactors.

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
