CHLORINATED ALKALINE DETERGENT FOR PIPELINE WITH METHANESULPHONIC ACID Russian patent published in 2014 - IPC C11D7/34 C11D7/10 C11D7/60 

FIELD: chemistry.

SUBSTANCE: invention relates to an improved multi-functional cleaning composition for the removal of food soiling, containing from 0.2 wt % to 10.0 wt % of a composition, which includes methanesulphonic acid or a salt of an alkali metal of the said acid; from 0.1 to 8.0 wt % of a composition, including hypochlorite, an effective quantity of an alkaline agent for the correction of the solution pH value to higher than 8; and at least one material, selected from threshold inhibitors, inhibitors of the deposit formation, chelating agents and tripolyphosphates. The said composition demonstrates an initial foam volume not less than 200 ml after the dynamic testing for foaming, in which 100 ml of 0.5% (vol./vol.) of the said composition applied dilution are placed into a 1 l cylinder with points, containing a spherical gas diffuser with 2.5 cm diameter, made from aluminium oxide, and a gas flow is passed through the diffuser at a rate of 1.5 l per minute for 15 s. The invention relates to a method of removing the food soiling with the application of the claimed composition, to a method of obtaining a multi-functional cleaning composition for the removal of the food soiling and to a diluting composition.

EFFECT: obtaining the cleaning composition for the reduction or prevention of deposits without an increase of the foam formation.
