Nonylphenol Ethoxylate (NP 9.5) Product Description
Nonylphenol Ethoxylate (NP 9.5) is a non-ionic surfactant derived from the ethoxylation of nonylphenol. It is characterized by its excellent wetting, emulsifying, and dispersing properties, making it a versatile ingredient in various industrial and consumer applications. NP 9.5 is particularly valued for its ability to enhance the solubility of hydrophobic substances in aqueous solutions, which is crucial in formulations where effective mixing and stability are required.
Key Features:
- Non-ionic Surfactant: NP 9.5 does not carry a charge, making it compatible with a wide range of other surfactants and formulations.
- Versatile Applications: Suitable for use in detergents, agricultural formulations, personal care products, and industrial cleaning agents.
- Environmental Considerations: While effective, NP 9.5 has raised environmental concerns due to its potential to bioaccumulate and disrupt endocrine systems in aquatic organisms.
Common Uses:
- Industrial Cleaning: Used in formulations for heavy-duty cleaners and degreasers.
- Agricultural: Acts as a wetting agent and emulsifier in pesticide formulations.
- Personal Care: Incorporated in shampoos, conditioners, and other cosmetic products for improved texture and performance.
- Textile Industry: Utilized in dyeing and finishing processes to enhance the penetration of dyes and chemicals.
