Description

Ammonium 2-Sulphonatoethyl Undec-10-Enoate is a specialized anionic surfactant derived from undecylenic acid, offering a unique combination of hydrophilic and oleophilic properties. This compound is valued for its excellent emulsifying, dispersing, and wetting capabilities, particularly in challenging formulations. It is primarily sought by manufacturers in the personal care, textile, and polymer industries for creating stable emulsions, improving fiber processing, and acting as a reactive intermediate.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in creams, lotions, and hair care products, providing a mild and skin-friendly profile.
• Textile Auxiliaries: Used as a wetting agent, dispersant, and softener in fiber pretreatment, dyeing, and finishing processes to enhance uniformity and handle.
• Polymerization & Emulsion Polymers: Serves as a reactive surfactant (surfmer) in the emulsion polymerization of styrene, acrylates, and vinyl acetate for improved latex stability and film properties.
• Industrial Cleaners & Detergents: Functions as a key component in formulations requiring high emulsifying power for oils and fats, especially in alkaline conditions.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide emulsions to enhance spreading, adhesion, and overall efficacy on plant surfaces.
• Leather Processing: Utilized in fatliquoring and dyeing stages to improve the penetration and distribution of oils and dyes within the leather matrix.

Quality Control

Our Ammonium 2-Sulphonatoethyl Undec-10-Enoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay by titration, residual moisture (KF), and identification by FT-IR, to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) documenting all specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture.
