Liquid-Plumr
From Infogalactic: the planetary knowledge core
Liquid-Plumr is a chemical drain opener made of 0.5–2% sodium hydroxide and 5–10% sodium hypochlorite, and a surfactant, produced by Clorox.
Three months after Procter & Gamble acquired Clorox in 1957, the Federal Trade Commission sued under the Clayton Act. After a decade of legal battles, the United States Supreme Court ordered P&G to divest itself of Clorox. Clorox became an independent company again on January 2, 1969 and in April 1969, Clorox pooled all its available cash and credit to buy Liquid-Plumr drain opener.
