Description

Merpol A is a high-performance, nonionic surfactant belonging to the alkylphenol ethoxylate class, identified by CAS No. 37208-27-8. It is valued for its exceptional wetting, emulsifying, and dispersing properties, which are critical for enhancing process efficiency and product performance in demanding industrial applications. This versatile chemical is essential for manufacturers in the textile, agrochemical, metalworking, and industrial cleaning sectors seeking reliable and effective surface-active agents.

Application

• As a key wetting and scouring agent in textile processing for desizing, bleaching, and dyeing operations.
• As an emulsifier in the formulation of agricultural chemicals, including pesticides and herbicides.
• As a primary component in industrial and institutional (I&I) cleaning products and metalworking fluids.
• As a dispersant and stabilizer in latex, paint, and coating formulations.
• In the paper and pulp industry as a de-inking agent and felt wash chemical.
• As an additive in oilfield chemicals for demulsification and drilling mud formulations.

Quality Control

Our Merpol A is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. While produced to meet general industrial specifications, we can provide material compliant with relevant regional regulatory frameworks. A comprehensive Certificate of Analysis (COA) detailing key parameters such as ethylene oxide content, hydroxyl value, and cloud point is available for every shipment upon request.

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, it is recommended to use an inert gas blanket to minimize oxidation. Keep container tightly sealed when not in use to prevent moisture absorption.
