Detailed Product Overview
Polyoxyethylene Nonylphenol (NP-9) is a nonionic surfactant characterized by its effective emulsifying, wetting, and dispersing capabilities. With a chemical formula of C15H24O9 and a molecular weight of 250.37 g/mol, NP-9 is synthesized through the ethoxylation of nonylphenol. This process results in a pale yellow to amber liquid that is soluble in water and has a density of 1.1 g/cm³. Its ability to reduce surface tension even at low concentrations makes it an ideal choice for a range of cleaning and disinfection applications. The product maintains stability under normal conditions, ensuring consistent performance across various industrial uses. NP-9 finds extensive use in industrial cleaning, household cleaning products, healthcare disinfection, and agricultural cleaning agents. Its efficacy in removing grease, oils, and dirt from surfaces makes it indispensable in formulating cleaning agents that require robust action. In healthcare settings, it is particularly valued for its role in disinfection, where it helps maintain stringent hygiene standards. Additionally, in agricultural applications, NP-9 aids in the removal of residues, enhancing the efficiency of cleaning processes. Its versatility and effectiveness make it a preferred choice in diverse sectors where surface cleanliness is critical. When considering NP-9 for your applications, it is essential to verify its industrial-grade quality, which guarantees a minimum purity of 90%. This high level of purity ensures optimal performance in demanding environments. The product's viscosity ranges from 100 to 300 cP, suitable for various formulations. Buyers should also check for the moisture content, which is kept below 0.5% to maintain the product's integrity. The pH of a 1% solution falls between 6.0 and 8.0, making it compatible with a wide range of other chemical agents. Ensuring these specifications are met upon delivery is crucial for achieving desired results in your processes. Proper handling and storage of Polyoxyethylene Nonylphenol (NP-9) are vital to preserving its quality and efficacy. The product should be stored in a cool, dry place, away from direct sunlight and heat sources, to prevent degradation. It is supplied in 25-liter containers, which are convenient for industrial-scale use. With a shelf life of 24 months, NP-9 remains effective when stored under recommended conditions. Due to its flammable nature, appropriate safety measures should be followed during handling, and users are advised to consult the material safety data sheet (MSDS) for detailed safety guidelines. Kivi Industrial Chemicals Limited ensures that NP-9 is supplied with all necessary documentation to facilitate safe and efficient use.
