Abstract
A drain cleaner composition of reduced toxicity comprises an organic solvent, preferably a water soluble solvent, a surfactant, preferably a fluorosurfactant, a hair decomposer such as a thioglycolate salt, a water soluble salt for increasing the density of the formulation, a thickener to increase the viscosity of the formulation. The composition is preferably formulated as an aqueous solution and other ingredients of reduced toxicity such as accelerators for hair decomposition, corrosion inhibitors, fragrances and dyes may also be included.
