Sodium Saccharin was first produced in 1879 by Constantin Fahlberg, who was a chemist working on coal tar derivatives at the Johns Hopkins Univers Sodium saccharin.
Throughout his research he accidentally discovered Sodium saccharins intensely sweet flavor. In 1884, Fahlberg applied for patents in several countries as he described methods of producing this chemical, which he called saccharin.
It is white crystal or power with inodorous or slight sweetness, easily soluble in water.
Its sweetness is around 500 times sweeter than that of sugar.
