Description

Sodium 1-Butyl 10-Hydroxy-9-Sulphonatooctadecanoate is a high-purity, anionic surfactant derived from octadecanoic acid, offering unique surface-active properties. This compound is valued for its excellent emulsifying, wetting, and dispersing capabilities in demanding formulations. It is a critical component for manufacturers in the personal care, industrial cleaning, and textile processing sectors seeking reliable performance and supply chain stability.

Application

• Personal Care & Cosmetics: Acts as a primary surfactant and emulsifier in shampoos, body washes, and facial cleansers for gentle yet effective cleansing.
• Industrial & Institutional (I&I) Cleaning: Used in heavy-duty degreasers, hard surface cleaners, and detergent formulations for superior oil and grease removal.
• Textile Processing: Serves as a wetting agent, dispersant, and emulsifier in dyeing and finishing processes to ensure even color application and fabric treatment.
• Agricultural Formulations: Employed as an adjuvant in pesticide and herbicide sprays to enhance droplet spread and active ingredient penetration on plant surfaces.
• Emulsion Polymerization: Functions as a critical emulsifier and stabilizer in the production of synthetic latexes, acrylics, and styrene-butadiene rubber (SBR).
• Metal Working Fluids: Incorporated into coolants and cutting fluids as an emulsifier to stabilize oil-in-water mixtures and provide lubricity.

Quality Control

Our Sodium 1-Butyl 10-Hydroxy-9-Sulphonatooctadecanoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications and consistent performance. A Certificate of Analysis (COA) documenting purity, physical characteristics, and compliance is available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and performance.
