Main properties:

  • STS is a good anti-caking and anti-blocking agent for powdered products in chemical processing, it can increase the solid content of the powder during the slurry drying processing

  • It also can work as coupling agent and processing aids in powdered chemicals processes, it can convert two-phase systems into homogeneous mixtures, lower the ingredients crystallization temperature and reducing the viscosity of liquid and complex formulations

Main Application

  • Detergent

  • Fertilizer

  • Pharmaceutical and other synthetic chemical processing


Application in detergent industry:
In the production of synthetic detergent powder, by the dosage of 2-3%, it can:

  • Lower the viscosity of the slurry, make the spray-drying easier, so the energy consumption can be lowered

  • Increase the moisture content in the made-product by 2~4%, so the cost can be lowered

  • Facilitate the hydration of STPP, make detergent powder capable of anti-caking, to improve the product quality

  • Reduce the loss of product in the tail gas of spray-dry tower, increase the output and reduce pollution



STS


Important Notice

  • STS has the feature of surfactant, so it's used as slurry adjusting agent in industrial synthetic processing

  • When the moisture is dried to the level of 12% or below, it will cake easily

  • We normally list 12 months as the shelf life in our COA, even in proper warehousing condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials), it's still suggested to avoid long time storage
