Description

Nonylphenol-Ethyleneoxidecondensates CAS NO 156609-10-8 are a class of nonionic surfactants produced by the ethoxylation of nonylphenol. These compounds are valued for their excellent wetting, emulsifying, and detergent properties, making them highly effective in a wide range of industrial formulations. They are essential raw materials for manufacturers in sectors requiring robust surface-active agents.

Application

• Industrial & Institutional (I&I) Cleaners: Key component in heavy-duty degreasers, floor cleaners, and metalworking fluids for superior soil removal and emulsification.
• Textile Processing: Used as a scouring, wetting, and leveling agent in dyeing and finishing operations to ensure uniform color and fabric quality.
• Agrochemical Formulations: Acts as an effective emulsifier and dispersant in pesticide and herbicide concentrates, enhancing spray coverage and efficacy.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid, improving color development and stability in water-based and solvent-based systems.
• Pulp & Paper Industry: Employed in de-inking processes and as a dispersant to improve pulp drainage and paper sheet formation.
• Oilfield Chemicals: Utilized in drilling muds and oil spill dispersants for their emulsifying and demulsifying properties.

Quality Control

Our Nonylphenol-Ethyleneoxidecondensates are manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance characteristics such as cloud point, hydroxyl value, and average molar ethoxylation number. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent oxidation.
