Description

Sodium 2-Hydroxy-3-Sulphonatopropyl Stearate is a high-purity anionic surfactant derived from stearic acid. This compound is valued for its excellent emulsifying, dispersing, and wetting properties, making it a versatile functional additive. It is primarily utilized in the formulation of industrial and institutional cleaners, textile processing aids, and personal care products where mildness and performance are required.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a primary surfactant and emulsifier in heavy-duty degreasers, floor cleaners, and metalworking fluids.
• Textile Processing: Serves as a wetting agent, lubricant, and softener in fiber processing, dyeing, and finishing operations.
• Personal Care & Cosmetics: Used as a mild co-surfactant and emulsifier in shampoos, liquid soaps, and skin cleansers.
• Leather Processing: Functions as a fatliquoring agent and emulsifier in leather tanning and finishing to improve softness and handle.
• Paper & Pulp Industry: Employed as a dispersant and processing aid in paper coating and de-inking formulations.
• Agricultural Formulations: Enhances the spreading and wetting of pesticides, herbicides, and foliar fertilizers.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking or degradation due to moisture absorption. Keep away from strong oxidizing agents.
