What are the suggested formulations using APSM?

Suggested formulations include replacing STPP with APSM in low-phosphate or phosphate-free detergent powders, often combined with LAS, AEO9, Sodium Silicate, and Sodium Carbonate.

What is the solubility of APSM in water?

APSM is easy to dissolve in water, with the capacity to dissolve more than 20g in 100ml of water at room temperature.

Product Q&A

Q:What is the main function of APSM in detergent powder?

APSM serves as a high-efficiency water softener and STPP replacement, offering superior calcium and magnesium exchange capacity with strong stain removal and compatibility with surfactants.

Q:How does APSM compare to STPP and 4A Zeolite?

APSM has a higher Ca2+ exchange capacity (320 min) than 4A Zeolite (286) and STPP (158). It offers better acid resistance than Zeolite and STPP, while maintaining good whiteness and solubility.

Q:What is the shelf life of APSM?

The COA typically lists 2 years as the shelf life. However, if stored in sealed bags away from direct sunlight, moisture, and incompatible chemicals, the actual shelf life is much longer.

Q:Can APSM completely replace STPP?

No, APSM cannot completely replace STPP because STPP enhances emulsifying and dispersing power for proteins and dust, and acts as an anti-caking agent by absorbing moisture to keep powder free-flowing.

Q:What are the key physical properties of APSM?

APSM is a white granular powder with a pH of 11 max, bulk density of 0.48-0.60 g/cm3, and particle size where over 90% passes through a 20-mesh sieve.
