211-522-5
29041000
Appearance: white powder
Physical and Chemical data:
| Melting Point | Flash point | Bulk Density |
| 300ºC min | 500ºC min | 0.50~0.70 |
Other Related indexes:
| EINECS | RTECS | PubChem | MDL | BRN |
| 211-522-5 | XT7350000 | 24849234 | MFCD00064388 | 3637479 |
Solubility: Easily soluble in water, soluble in methanol, slightly soluble in most organic solutions, Solubility in water is as below
| Temperature (ºC) | 20 | 80 |
| Solubility by (g) | 67 | 260 |
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
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 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
