Description

Sodium 2-Sulphonatoethyl Undec-10-Enoate is a specialized anionic surfactant derived from undecylenic acid, featuring a terminal double bond and a sulfonate group. This unique molecular structure provides excellent wetting, emulsifying, and dispersing properties, making it a valuable functional additive in advanced formulations. It is particularly sought after by manufacturers in the personal care, textile, and specialty polymer industries for its ability to modify surface properties and enhance product performance.

Application

• Personal Care & Cosmetics: Acts as a primary or co-surfactant in shampoos, body washes, and facial cleansers, offering mildness and stable foam.
• Textile Processing: Used as a wetting agent, emulsifier, and dispersant in dyeing and finishing baths to ensure even color distribution and fabric treatment.
• Polymer & Emulsion Synthesis: Serves as a reactive surfactant (surfmer) in emulsion polymerization processes, such as for acrylics and styrene-butadiene, to improve latex stability and particle size control.
• Industrial Cleaners & Detergents: Enhances the cleaning efficacy of hard-surface and industrial detergents by effectively lowering surface tension and emulsifying oils.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide formulations to improve spray coverage and active ingredient penetration.
• Leather Processing: Functions as a fatliquoring and wetting agent in the tanning process to ensure soft, uniform leather.

Quality Control

Our Sodium 2-Sulphonatoethyl Undec-10-Enoate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and physical characterization, to ensure it meets precise specifications for industrial and cosmetic applications. Certificates of Analysis (COA) documenting purity, identity, and 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, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
