<p>Thickened aqueous alkali metal hypochlorite compositions are provided by adding to the aqueous solution of the hypochlorite an effective amount of a thickening additive composed of at least one of each of the following classes of anionic surfactants: (A) alkali metal sulfate salts of ethoxylated aliphatic alcohols; (B) alkali metal salts of N-alkyl, N-acyl amino acids, and (C) alkali metal salts of alkyl sulfates. The thickened compositions have viscosities of at least 25 centipoises and remain stable-no phase separation; maintain viscosity and hypochlorite concentration-for extended periods. Compositions especially useful for unclogging clogged drains, preferably those with P-traps, are described.</p> |
