High-quality polyether F-6 is a nonionic surfactant with excellent defoaming and foam suppression performance as its core feature, coupled with outstanding chemical stability, resistance to acids, alkalis, and hard water, low toxicity, environmental friendliness, and wide application.
Detailed Description
High-quality polyether F-6 (CAS No.: 61791-12-6), with the chemical name castor oil polyoxyethylene ether (also known as emulsifier EL, PEG castor oil, ethoxylated castor oil), belongs to nonionic surfactants. The product appears as a light yellow to yellow transparent viscous liquid and is one of the core products of Guoli Chemical in the field of industrial defoaming and low-foam additives. Its molecular structure combines the hydrophobic group of castor oil with the hydrophilic group of the polyoxyethylene chain, enabling it to exert stable interfacial activity in various industrial media.
The primary characteristic of this product is its excellent defoaming and foam suppression performance—only a small amount is needed to quickly eliminate existing foam and inhibit foam regeneration for an extended period. This is particularly critical in scenarios with stringent foam control requirements, such as fermentation processes, paper pulping, textile printing and dyeing, and industrial wastewater treatment. At the same time, F-6 exhibits outstanding resistance to acids, alkalis, and hard water, maintaining high efficiency and stable defoaming performance across a wide pH range and under high-hardness water conditions without easy failure.
Furthermore, high-quality polyether F-6 has excellent chemical stability, is not prone to adverse reactions with other additives in the formulation (such as dispersants, chelating agents, fungicides, etc.), and has broad compatibility, facilitating flexible formulation by formulators. From an environmental perspective, the product is low in toxicity, non-irritating to skin and eyes, non-flammable, and easily biodegradable, meeting the requirements of green chemistry and sustainable development, making it a safe and environmentally friendly industrial additive choice.

Application Recommendations
The applications of high-quality polyether F-6 cover multiple industrial fields, with specific recommendations as follows:
- Core Component of Defoamer: As the main raw material of high-efficiency defoamer, it is suitable for foam control in fermentation processes, paper pulping, textile printing and dyeing, water-based coatings, and industrial wastewater treatment. It is recommended to add in small amounts to achieve rapid bubble breaking and long-term foam suppression.
- Industrial Low-Foam Cleaner: Used in formulating low-foam cleaners for spray cleaning, high-pressure cleaning, etc., it reduces foam while maintaining good wetting, penetration, and decontamination capabilities, especially suitable for metal and hard surface cleaning.
- Metalworking Fluids: As a lubricating and cooling base component in cutting fluids and grinding fluids, it reduces friction and processing temperature, improves workpiece surface finish, and also exhibits hard water resistance and emulsion stability.
- Textile Pretreatment Auxiliaries: Used as a penetrant and degreasing agent in processes such as desizing, scouring, and bleaching, it helps the working liquid quickly and uniformly wet the fabric, improving pretreatment efficiency.
- Water Treatment Chemicals: As a dispersant, scale inhibitor, or heat transfer medium additive, it improves system operation efficiency and equipment protection capabilities.
Precautions
- It is recommended to wear chemical-resistant gloves, safety goggles, and laboratory work clothes during operation to avoid direct contact with skin and eyes.
- Storage temperature should be maintained at 5°C to 35°C, avoiding freezing and high-temperature exposure. Use sealed containers made of stainless steel, glass, or HDPE.
- Store separately from incompatible substances such as strong oxidizers, strong acids, and strong alkalis.
- Although it is a non-flammable liquid, anti-static measures are recommended during large-scale transfer.
- In case of skin contact, rinse thoroughly with plenty of water and mild soap for at least 15 minutes; in case of eye contact, rinse thoroughly with flowing clean water or saline for at least 15 minutes; if discomfort persists, seek medical attention.
- Expired products (over 12 months) should be re-tested and approved before further use.
