Description

Disodium 10-(Sulphonatooxy)Octadecanoate is a specialized anionic surfactant derived from stearic acid, featuring a sulfonated ester group that enhances its solubility and surface-active properties. This compound is valued for its ability to act as an effective emulsifier, dispersant, and wetting agent in complex formulations. It is primarily utilized in industries such as agrochemicals, textiles, and personal care, where stable emulsions and improved substrate wetting are critical for product performance.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates, improving sprayability and foliar adhesion.
• Textile Processing: Used as a wetting agent and detergent in scouring, dyeing, and finishing baths to ensure even dye penetration and soil removal.
• Personal Care & Cosmetics: Serves as a mild surfactant and emulsifier in creams, lotions, and hair care products, providing stable oil-in-water emulsions.
• Industrial Cleaners: Functions as a powerful wetting and cleaning agent in heavy-duty degreasers and institutional cleaning products.
• Leather Processing: Employed in tanning and fat-liquoring operations to aid in the even distribution of oils and dyes.
• Paints & Coatings: Enhances pigment dispersion and stabilizes emulsion paints, improving color consistency and shelf life.
• Paper Manufacturing: Used in pulping and coating processes to improve fiber wetting and coating uniformity.

Quality Control

Our Disodium 10-(Sulphonatooxy)Octadecanoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
