Description

Lignosulfonic Acid, Ethoxylated, Sodium Salts is a chemically modified, water-soluble anionic surfactant derived from renewable lignin. This product matters for its unique combination of excellent dispersing, emulsifying, and binding properties, making it a versatile and eco-friendly additive. Industries such as construction, agriculture, ceramics, and oilfield chemicals need it for its ability to improve process efficiency and material performance.

Application

• Construction Industry: Acts as a highly effective plasticizer and water-reducing agent in concrete and cement formulations, improving workability and final strength.
• Agricultural Formulations: Serves as a key dispersant and stabilizer in pesticide and herbicide suspensions and emulsions, enhancing spray coverage and efficacy.
• Ceramics & Refractories: Used as a binder and deflocculant in ceramic slips and refractory castables, ensuring uniform particle suspension and improved green strength.
• Oilfield Chemicals: Functions as a fluid loss control additive and dispersant in drilling muds, helping to stabilize the borehole and manage rheology.
• Dye & Pigment Industry: Employed as a grinding aid and dispersant for inorganic pigments and dyes, preventing agglomeration and ensuring color consistency.
• Industrial Cleaners: Utilized in alkaline and acidic cleaning formulations for its surfactant and soil-suspending properties.
• Textile Processing: Acts as a leveling and dispersing agent in dye baths to achieve uniform coloration.
• Pellet Binder: Used in the agglomeration of fine powders (e.g., fertilizers, animal feed) to form durable, dust-free pellets.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and performance for industrial applications. We adhere to a comprehensive quality management system. Certificates of Analysis (COA) are provided with each shipment, detailing key parameters such as active content, pH, and sulfonate group concentration. While produced to industrial grade standards, specifications can be aligned with customer-specific requirements.

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 caking and degradation due to moisture absorption. Keep away from strong oxidizing agents.
