Description

2-(2-Hydroxy-3-Sulfopropoxy)-3-[1-[[(3-Methylheptyl)Oxy]Methyl]-2-Sulfoethoxy]-1-Propanesulfonic Acid Trisodium Salt is a high-purity, multi-sulfonated anionic surfactant and complexing agent. This compound matters for its exceptional ability to chelate metal ions and function as a powerful dispersant and wetting agent in demanding formulations. Industrial users in sectors like agrochemicals, textiles, and advanced material synthesis need it for its superior performance in stabilizing emulsions and preventing scale formation.

Application

• Agrochemical Formulations: Acts as a superior wetting agent, dispersant, and stabilizer in pesticides, herbicides, and fungicides to enhance efficacy and shelf-life.
• Textile Processing: Used in dyeing and printing processes as a leveling agent and to improve color fastness and fabric handle.
• Industrial Cleaning & Detergents: Serves as a key component in heavy-duty cleaners and detergents for its excellent emulsifying and soil-suspending properties.
• Construction Chemicals: Functions as a plasticizer and water-reducing agent in concrete admixtures and cement formulations.
• Oilfield Chemicals: Employed as a scale inhibitor and surfactant in drilling fluids and enhanced oil recovery (EOR) processes.
• Paper & Pulp Industry: Utilized as a dispersant for pigments and fillers to improve paper quality and production efficiency.
• Metal Treatment & Plating: Acts as a complexing agent in electroplating baths and metal surface treatment solutions.
• Personal Care & Cosmetics: Can be used in specialized rinse-off products as a mild surfactant and viscosity modifier.

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 after opening to prevent absorption of atmospheric moisture, which can lead to caking or performance degradation. Keep away from incompatible materials such as strong oxidizing agents.
