Dilute aqueous compositions for removing soap scum consisting essentially of sodium carbonate, hypochlorite bleach, alkali metal hydroxide and a surfactant system consisting either of sodium 2-ethylhexyl sulfate and myristyldimethylamine oxide or of sodium 2-ethylhexyl sulfate alone.

Dilute aqueous compositions for removing soap scum consisting essentially of sodium carbonate, hypochlorite bleach, alkali metal hydroxide and a surfactant system consisting of sodium 2-ethylhexyl sulfate and a C.sub.8 -C.sub.10 -alkyldimethylamine oxide.

Aqueous cleaning compositions containing 2-ethylhexyl sulfate and C.sub.8

The inventive compositions are pourable aqueous bleach composition which contain abrasives, suitable for use in cleaning hard surfaces such as are found, for example, in lavatories and kitchens. The compositions of the invention show good shelf life, exhibit a high level of bleach stability and show good stain and soil removal, particularly from hard surfaces.

Pourable, thickened aqueous bleach and abrasive containing compositions

A hard surface scouring cleaner composition comprises, by weight, (a) from 0.5 to 10% of soft abrasive particles, (b) from 0.5 to 2.5% of a chlorine-containing bleach, (c) from 0.2 to 3.0% of a thickening system comprising from 0.2 to 3.0%, based on the weight of the composition, of a cross-linked polyacrylate resin having a molecular weight in the range of 1,000,000 to 10,000,000 and from 0 to 2.5% of a synthetic smectite clay, (d) from 0.25 to 3.0% of a bleach-stable surfactant system comprising mainly anionic surfactants, (e) from 0 to 3.0% of an electrolyte selected from the group comprising sodium or potassium carbonates or silicates, and (f) sufficient amount of sodium or potassium hydroxide to provide a pH in the range of 11.5 to 13.5. These compositions have an apparent viscosity as measured on a Brookfield RVTDV-II with a #6 spindle at 50 rpm of from 0.5 to 7 Kcps and at 1 rpm of from 10 to 150 Kcps. The abrasive particles are preferably organic particles such as polyethylene or polypropylene.

Stable bleach-containing cleansing compositions with soft abrasives

The present invention is a process for decreasing the concentration of a lignin-containing organic carbon in an aqueous system by a combination of ozone and hydrogen peroxide. The process is particularly useful for decolorizing lignin-containing aqueous solutions such as effluents from a pulp mill.

Purification of waste streams

A method for stabilizing hydrogen peroxide and the stabilized composition are claimed employing as a stabilizer a tin (II) salt of an acid selected from the group hydrofluoric acid, C6 to C17 saturated monocarboxylic acids and C2 to C6 saturated polycarboxylic acids, preferably oxalic acid. The tin content of hydrogen peroxide prepared from a tin (II) oxalate stock solution can be reduced by filtration to less than 1 mg/l if the tin oxalate stock solution has been properly aged.

Tin (II) stabilizer for hydrogen peroxide

A high yield process is provided for treating lignocellulose food fiber to sanitize and bleach the fiber. The process is not only a high yield process but produces better or equivalent bleaching than alternative processes and further does not produce a waste disposal problem. The process also has the advantage of requiring very little energy compared to alternative processes.
