According to the National Institutes of Health's Household Products Database, the crystal form is composed of:
After Drano crystals are added to water, the reaction works as follows:
Crystal Drano was invented in 1923 by Harry Drackett. For years, Drackett advertised Once every week, Drano in every drain.
Bristol-Myers bought the Drackett Company in 1965 and sold it to S. C. Johnson in 1992. Drano has been developed into several forms; as of 2016[update] ,the original Crystal Drano® is marketed as Drano® Kitchen Crystals Clog Remover.
Drano Aerosol Plunger was developed in the late 1960s, intended as a safer product that would be kinder environmentally. It was basically just a can of CFC propellant, the best-known brand of which was Freon. After Earth Day in 1970, there came increasing pressure to eliminate CFC propellants. Drackett used cheaper propellants, a blend of propane and butane, in all its other products. However, the propellant mix created a fire hazard.
The product was problematic. The forceful propellant required most consumers use both hands to control the can, plus another hand or two to hold a rag over the drain vent to contain the pressure. The pressure sometimes knocked apart poor plumbing without blasting free the clog. Consumers who ignored instructions and attempted to use chemical drain openers first could be chemically burned from blow-back.
Liquid Drano was introduced in response to Clorox's purchase of Liquid-Plumr in 1969. Originally, it was simply a liquid lye (sodium hydroxide). In the late 1970s, the product was reformulated as a combination of liquid lye and sodium hypochlorite. Sodium hypochlorite is used in low (5% concentration) as laundry bleach and in higher concentrations as a swimming pool disinfectant.
Liquid Drano is marketed in several forms, including Drano Liquid Clog Remover, Drano Max Build-Up Remover and Drano Dual-Force Foamer Clog Remover. All are variations on the basic Liquid Drano formula.
