Rock Salt Soap Bar
For manufacturing soaps, detergents and glycerine, salt is one of the most important raw materials that fulfill the quality requirements of soap manufacturing industry.
Soap Industry most important raw material is salt and it is requires for softening and mushiness of soap. Hub-Pak has been manufacturing five different grades of salt for soap, detergent and glycerine industries.
The manufacturing process of soap, detergent and glycerin involves the use of salt. During this process, the soap is washed with concentrated brine solution (NaCl) to separate glycerin. This is done after the saponification reaction.
The solubility of soap in water increases with an increase in the size of monovalent cation. Similarly, an increase in divalent cation (Ca & Mg) results in a decrease in the solubility. The increase in the water solubility leads to the softness and mushiness of the soap. The divalent ions, Ca & Mg, cause problems during the manufacturing process of the soap by making it mushy and soft.
There are different grades of salt that fulfill the requirements of the manufacturers of soap, detergent and glycerin manufacturers. In total, there are 5 different grades offered by Hub-Pak to these manufactures
