Description

Sulfuric Acid, Mono-C12-13-Alkyl Esters, Compds. With Ethanolamine is a specialized anionic surfactant derived from the reaction of C12-13 fatty alcohols with sulfuric acid, subsequently neutralized with ethanolamine. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a versatile performance additive in industrial formulations. It is a critical component for manufacturers in the personal care, textile processing, agrochemical, and industrial cleaning sectors seeking stable and effective surfactant systems.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and emulsifier in shampoos, body washes, and facial cleansers, providing rich lather and mild cleansing.
• Textile Processing: Used as a wetting agent, scouring aid, and emulsifier in fiber preparation, dyeing, and finishing baths to ensure uniform processing.
• Industrial & Institutional (I&I) Cleaning: Serves as a key ingredient in heavy-duty degreasers, floor cleaners, and metal cleaning formulations for its superior oil emulsification.
• Agrochemical Formulations: Functions as an effective emulsifier and dispersant in pesticide and herbicide concentrates, enhancing sprayability and target adhesion.
• Paint & Coatings: Employed as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Leather Processing: Used in fatliquoring and dyeing processes to aid in the even penetration and distribution of oils and dyes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperatures (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from strong oxidizing agents.
