Abstract: A contaminated surface polishing-washing detergent composition comprises a polishing media and a dispersion medium wherein at least a part of the polishing media is made of a fine powder of an RB ceramic and/or CRB ceramic. The composition is effective in polishing-washing the surfaces of a precision-worked base material, and after the polishing-washing, the particles of metal oxides and the particles of removed burrs and the cutting metal chips are simply separated from the composition by use of the difference in specific gravity to re-use it by recycling.
Abstract: Provided are aqueous cleaning and surface treatment compositions for use in the general or localized cleaning of fibers and fibrous substrates, including carpets, carpet fibers as well as textiles. The compositions include an oxidizing agent constituent, preferably hydrogen peroxide, an anionic surfactant, especially an alkyl sulfate, an organic solvent, preferably a ternary solvent system which includes ethylene glycol hexyl ether, propylene glycol methyl ether and isopropyl alcohol, and an antiresoiling compound which is essentially free of fluorine atoms, preferably one based on a polymeric material which is essentially free of fluorine atoms, and water. Preferably the composition is essentially free of fluorine atoms.
The compositions exhibit good cleaning efficacy, and excellent shelf stability exhibited by low loss of the hydrogen peroxide subsequent to accelerated aging tests.
