摘要： Drain-pipe cleaning compositions of the sodium hydroxide -- aluminum chip -- sodium nitrate type possess the added capability of dissolving or disintegrating proteinaceous fibrous material, without impairment of their capability of removing grease deposits, when they have a small content of a water-soluble glycoluril or a glycoluril derivative.The compositions are specially useful for freeing drain-pipes which are clogged by fatty deposits containing animal hair.
