Applications

The BGF series offers a wide range of applications due to their excellent surface-active properties:

1. Cleaning Agents: The products have superior cleaning performance with low foaming and low odor, making them suitable for both industrial and residential cleaning agents.

2. Textile Industry: They are used as textile refining agents, providing good wetting properties and improving the smoothness and elasticity of fabrics.

3. Coatings and Additives: The surfactants can be used as additives in coatings, enhancing the performance of the formulations.

4. Pesticides and Chemicals: They serve as wetting agents, emulsifiers, and co-emulsifiers in pesticide formulations and other chemical products.

5. Synthetic Fiber Industry: The products can be used as components in synthetic fiber oils, providing emulsifying properties and static electricity removal.

6. Enhanced Oil Recovery (EOR): Recent studies have explored the potential of these surfactants in EOR applications, demonstrating good interfacial activity and oil displacement effects.

Environmental and Safety Considerations

Cashew Phenol Polyoxyethylene Ether is highly biodegradable and does not contain alkylphenol polyoxyethylene ether (APEO) after biodegradation, avoiding potential harm to the environment and biological systems. The products are non-toxic and non-flammable, and can be stored and transported under general chemical regulations.

Quality and Specifications

The BGF series includes several grades, each with specific properties
