Compsn. for clearing pipes blocked with hairy material - contg. alkali, alkaline metal nitrate, light metal and glycouril or its derivatives

A prod. for cleaning blocked pipes, partic. for removing hair and similar material, based on a solid mixt. of an alkali metal hydroxide, light metal shavings and an alkali or alkaline earth metal nitrate also contains 0.5 to 5% of glycoluril or its derivs. The pref. compsns. contain 50-80% NaOH, 4-10% Al tumings, 15-40% NaNO3, and 0.5-5% of glycoluril or its derivs. Specified glycoluril derivs. are tetra-acetyl, 1,4-diacetyl, tetrapropionyl, 1,4-dipropionyl, dichloro and tetrachloro-glycoluril.

DRAIN CLEANERS WITH HAIR-DISINTEGRATING PROPERTIES

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 drainpipes which are clogged by fatty deposits containing animal hair. -A- ...
