AQUEOUS COMPOSITION CONTAINING HYDROGEN PEROXIDE AND USE THEREOF IN CLEANING SURFACES Russian patent published in 2011 - IPC C11D3/39 C11D3/37 C11D3/20 

FIELD: chemistry.

SUBSTANCE: aqueous composition has pH equal to or less than 3, and contains the following ingredients (per total weight of the composition) : a) 0.05-20 wt % polymer thickener containing 20-100000 monomer links and an average of at least 0.8-COOR groups per monomer link, where for each separate -COOR group, R is independently selected from H, OH, and a carbon-containing group, b) 0.05-30 wt % hydrogen peroxide in terms of H₂O₂, c) 0.5-60 wt % one or more aliphatic carboxylic acids containing 1-8 carbon atoms, their alkyl esters, anhydrides and/or peroxy acids. Content of active oxygen, which is ensured by presence of ingredients a) and c) is equal to at least 0.02 wt % (per total weight of the composition).

EFFECT: obtaining a stable aqueous composition with low pH for cleaning different surfaces and for bleaching textile materials or paper.
