FIELD: chemistry.

SUBSTANCE: preparation contains components with the following ratio counted per pure substances and taking into account neutralisation reactions, wt %: alkali metal hydroxide 3-9%, salt of ethylenediaminotetraacetic acid 1-6%, tetrasodium salt of oxyethylenediphosphonic acid 3-13%, sodium silicate 0.1-3%, alkylpolyglycozide with length of alkyl chain C₆-C₁₂ 1-7%, mixture of anionic SAS 3-12%, sodium citrate 0.1-6%, sodium tripolyphosphate 0.1-5%, alkylated derivative of β-alanine of general formula RR'NCH₂COONa, where R is alkyl radical of C_nH_2n+1 type at n from 8 to 18, R'=H,CH₂COOM¹, where M¹=H, Na, K 0.1-6%, amine oxide of general formula R₁NOR₂R₃, where R₁ is alkyl radical C_nH_2n+1, at n from 6 to 18, R₂, R₃ are alkyl radicals C_nH_2n+1 at n from 1 to 3m, counted per pure substance 0.2-5%, non-ionogenic polyethoxylated SAS 1-8%, sodium alphaolefinsulphonate of general formula C_nH_2nSO₃Na, where n=14-18, R is any alkyl radical counted per pure substance 0.5-5%, alkylamidopropylbetaine in zwitter-ionic form: RCO(CH₂)₃N⁺Me₂CH₂COO^-, where R is alkyl radical with chain length C₈-C₁₈ 0.1-5%, low-ethoxylated alcohols of linear or branched structure of general formula C_nH_2n+1(OCH₂CH₂)_mOH, at n from 1 to 6 and m from 1 to 5 - 0.1-5%, dye 0.05-0.5%, water - the remaining part.

EFFECT: increase of uniformity of surface cleaning by provision of continuity of foam covering.
