Other formulations have been developed over time. In 1916, Marcel Daufresne substituted sodium bicarbonate for Dakin's boric acid as buffering agent. [7] [17] This formulation is the basis of current commercial products. [18] The concentration chosen by Dakin (0.5%) was the maximum highest concentration found tolerable to the skin.
It has very low toxicity to higher organisms such as human cells, which have more complex and protective membranes. Common sodium bicarbonate (NaHCO 3) has antifungal properties, [39] and some antiviral and antibacterial properties, [40] though those are too weak to be effective at a home environment. [41]
Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −). Sodium bicarbonate is a white solid that is crystalline but often appears as a
Dilute sodium hypochlorite (i.e. a mild bleach) is the main constituent of several brands of denture cleanser. Other ingredients include such chemicals as: sodium bicarbonate – or baking soda, which alkalizes the water, cleaning the dentures; citric acid – removes stains; sodium perborate; sodium polyphosphate
Cleaning agents or hard-surface cleaners are substances (usually liquids, powders, sprays, or granules) used to remove dirt, including dust, stains, foul odors, and clutter on surfaces. [1] Purposes of cleaning agents include health , beauty, removing offensive odors, and avoiding the spread of dirt and contaminants to oneself and others.
The carbon dioxide is generated by a reaction of a compound containing bicarbonate, such as sodium bicarbonate or magnesium bicarbonate, with an acid such as citric acid or tartaric acid. Both compounds are present in the tablet in powder form and start reacting as soon as they dissolve in water. [1] [2] [3] [4]

Eno was first marketed by James Crossley Eno (1827–1915). [4] Legend has it that his idea for the product arose while he was working at the pharmacy of an infirmary in Newcastle, Britain, with Dennis Embleton; Embleton often prescribed an effervescent drink made by mixing sodium bicarbonate and citric acid in water, and Eno adopted this beverage.
