Description

1-Methyl 2-Sulphododecanoate is a specialized anionic surfactant and sulfonated ester compound, identified by CAS NO 64131-25-5. This chemical is valued for its excellent emulsifying, wetting, and dispersing properties, making it a critical performance additive in demanding formulations. It is primarily sought by manufacturers in the personal care, industrial cleaning, textile processing, and specialty chemical synthesis sectors.

Application

• Personal Care Formulations: Acts as a primary or co-surfactant in shampoos, body washes, and facial cleansers for rich lather and mildness.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, alkaline cleaners, and floor care products for superior wetting and soil suspension.
• Textile Auxiliaries: Serves as an effective wetting agent and emulsifier in dyeing and finishing processes.
• Emulsion Polymerization: Functions as a surfactant in the production of acrylic, vinyl acetate, and styrene-butadiene lattices.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
• Leather Processing: Used in fatliquoring and dyeing stages to improve penetration and uniformity.
• Metal Working Fluids: Provides emulsification and lubrication in synthetic and semi-synthetic coolants.

Quality Control

Our 1-Methyl 2-Sulphododecanoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and impurity profile 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, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture which may affect quality.
