ABSTRACT:
This invention relates to drain cleaning compositions characterized by a pelletized form. Each pellet formed comprises aluminum; potassium or sodium nitrate; a binding material having a melting point of from about 37.degree. C. to about 67.degree. C. selected from the group consisting of polymers of polyethylene glycol, having a molecular weight of from about 3000 to about 20,000; polymers of ethylene oxide, having a molecular weight of from about 400,000 to about 2,000,000; aliphatic oxyethylated straight chain fatty alcohols having a molecular weight of about 260 to about 265 and containing about 80%, by weight, ethylene oxide; fatty acids having a carbon chain length of from about 10 to about 18 carbon atoms; alkali metal salts of gluconic acid; and mixtures thereof; at least about 1%, by weight, of an alkali metal hydroxide; and a sufficient amount of an additional compatible alkaline ingredient, whereby the total alkaline concentration present, expressed as sodium oxide, is at least about 11%, by weight.
