ABSTRACT:
A drain cleaning composition includes at least about 40% by weight of a free-flowing coated alkali metal hydroxide and about 5% to 20% by weight of mixture of a hypochlorite generator and a peroxide generator. The hypochlorite and peroxide generators react to release oxygen gas and hypochlorite ions, the hypochlorite generator being in stoichiometric excess over the peroxide generator to produce free hypochlorite ions for dissolving hair and other protein based clogs. The coating on the drain cleaning composition prevents the hydroxide from reacting with the other components of the mixture before the mixture is added to water.
