Description

Polyethylene Glycol Carboxymethyl C12-13-Alkyl Ether, Na is a high-performance, anionic surfactant derived from ethoxylated C12-13 alcohols. This compound is valued for its excellent emulsifying, dispersing, and detergent properties, particularly in challenging formulations. It is a critical ingredient for industrial and institutional cleaning products, personal care formulations, and textile processing aids where robust performance under varied conditions is required.

Application

• Industrial & Institutional (I&I) Cleaners: A key surfactant in heavy-duty liquid detergents, degreasers, and floor cleaners for its superior grease-cutting and soil suspension capabilities.
• Personal Care & Cosmetics: Used as an emulsifier and foaming agent in shampoos, body washes, and liquid soaps, providing mildness and stable lather.
• Textile Processing: Functions as a wetting agent, scouring aid, and dye dispersant in fabric preparation and dyeing processes.
• Emulsion Polymerization: Acts as a stabilizer and emulsifier in the production of acrylic, vinyl acetate, and other polymer lattices.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide formulations to enhance spreading, wetting, and adherence on plant surfaces.
• Metal Working Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and synthetic coolants.

Quality Control

Our Polyethylene Glycol Carboxymethyl C12-13-Alkyl Ether, Na is manufactured under a strict quality management system. Every batch is tested to ensure consistent performance, including parameters such as active matter content, pH, and ionic character. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
