Description

Sodium Hydrogen 9-Sulphonatooctadecenoate is a high-purity anionic surfactant derived from oleic acid. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in aqueous systems. It is a critical raw material for formulators in the personal care, industrial cleaning, and textile processing industries seeking effective and stable anionic agents.

Application

• Personal Care & Cosmetics: Used as a primary surfactant or co-surfactant in shampoos, body washes, and facial cleansers for its mildness and rich lather.
• Industrial & Institutional (I&I) Cleaners: Serves as a key ingredient in heavy-duty degreasers, metal cleaners, and floor care formulations due to its powerful emulsification of oils and fats.
• Textile Auxiliaries: Employed as a wetting agent, scouring aid, and dye leveling agent in textile pretreatment and dyeing processes.
• Emulsion Polymerization: Acts as an effective emulsifier and stabilizer in the production of synthetic rubbers, latex paints, and acrylic dispersions.
• Agricultural Formulations: Enhances the spreading and adhesion of pesticides, herbicides, and fungicides on plant surfaces.
• Leather Processing: Used in soaking, degreasing, and fatliquoring stages to improve leather softness and uniformity.

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); keep the original container tightly sealed to prevent absorption of atmospheric moisture which may lead to caking or reduced efficacy.
