LIQUID COMPOSITION FOR CLEANING AND/OR DEEP CLEANING Russian patent published in 2017 - IPC C11D3/14 C11D3/37 C11D17/00 

FIELD: chemistry.

SUBSTANCE: liquid composition for cleaning and/or deep cleaning is described, comprising non-spherical and/or non-rolling (sharp) abrasive cleaning particles based on foam, obtained by foam structure crushing, at that, the said foam-based abrasive particles are prepared by a process comprising the following steps: (i) a homogeneous solution is obtained containing at least one thermoplastic material with a raw density of more than 1.15; (ii) the said homogeneous solution is foamed by extrusion foaming through the die with an opening size to provide foam expansion ratio of 8 to 14; (iii) the said foam is fragmented to obtain- foam-based abrasive particles.

EFFECT: provision of effective treatment and surface safety profile.
