High-Quality Polyether F-6 (CAS No.: 61791-12-6), also known as castor oil polyoxyethylene ether, emulsifier EL, PEG castor oil, ethoxylated castor oil, is a nonionic surfactant produced by Haian Guoli Chemical Co., Ltd. The product appears as a light yellow to yellow transparent viscous liquid, belonging to polyoxypropylene glycerol ether compounds.
The most prominent feature of this product is its excellent defoaming and foam inhibition performance — it can quickly break foam with a small addition and suppress foam regeneration for a long time. At the same time, it has excellent resistance to acids, alkalis, and hard water, maintaining stability and efficiency across a wide pH range and under complex water conditions. Additionally, the product has good chemical stability, does not easily react adversely with other additives, has broad compatibility, and is low-toxic, environmentally friendly, and easily biodegradable, meeting green chemical requirements.
From a safety perspective, High-Quality Polyether F-6 is a non-hazardous chemical, non-irritating to skin and eyes, non-flammable, and poses no significant harm to humans or the environment under normal use conditions, making it a relatively safe industrial additive raw material.
1. Defoamer Component (Core Use) — As a core raw material for high-efficiency defoamers, it is widely used for foam control in processes such as fermentation, paper pulping, textile printing and dyeing, water-based coatings, and industrial wastewater treatment, providing long-lasting foam suppression and rapid foam breaking.
2. Industrial Low-Foam Cleaners — Used to formulate low-foam cleaners, reducing foam generation in processes such as spray cleaning and high-pressure cleaning while maintaining good wetting, penetration, and detergency, especially suitable for metal and hard surface cleaning.
3. Metalworking Fluid Component — As a basic component for lubrication and cooling in cutting fluids and grinding fluids, it reduces friction and processing temperature, improves workpiece surface finish, and exhibits excellent hard water resistance and emulsification stability.
4. Textile Pretreatment Auxiliary — Used as a penetrant and degreaser in pretreatment processes such as desizing, scouring, and bleaching, helping the working fluid quickly and evenly wet the fabric, improving pretreatment efficiency and quality.
5. Water Treatment Chemicals — In water treatment formulations, it can be used as a dispersant, scale inhibitor, or heat transfer medium additive to improve system operation efficiency and equipment protection.

In defoamer formulations, High-Quality Polyether F-6 is typically used as the core defoaming component. It is recommended to determine the dosage based on the foam level of the specific process (generally 0.01%-0.5% of the total system), and it can be used alone or combined with synergistic components such as hydrophobic silica. In cleaners and metalworking fluids, the recommended dosage is 1%-5% of the total formulation, and the optimal ratio should be determined through experimental optimization.
