Product details

Uses:

1. Used as slurry conditioner in chemical industry and synthetic detergent; used as water co-solvent in synthetic detergent, and it can increase water content when added into powder detergent, and it has good effect on fluidity, handfeel, anti-caking etc. it is also used as crystallization additive in the production of chemical fertilizer.

2. In liquid detergent, it is mainly used as solubilizer, after adding sodium p-toluenesulfonate, the viscosity and cloud point will be reduced. when using, we should pay attention to the content of raw materials, inorganic salts and solubility. especially for liquid detergent, the salt content has a great influence on the transparency of the liquid.

3. Used in organic synthesis industry, in medicine for the synthesis of doxycycline, pansentin, naproxen and for the production of amoxicillin, cefadroxil intermediates.
