DETERGENT FOR METALLIC SURFACE CLEANSING Russian patent published in 2002 - IPC

FIELD: detergents. SUBSTANCE: invention proposes a detergent comprising the following components, g/l: caustic soda, 0.9-3.3; sodium tripolyphosphate, 0.72-2.64; soda ash, 2.82-10.34; sodium metasilicate, 0.6-2.2; oxyethylated monoalkylphenol based on propylene trimmers and containing 12 moles of ethylene oxide in molecule, 0.024-0.088; oxyethylated monoalkylphenol based on propylene trimmers containing 6 moles of ethylene oxide in molecule, 0.036-0.132; trisodium phosphate, 0.84-3.08; polyoxyethylene glycol esters of synthetic primary higher saturated alcohol of C₁₆-C₂₀-fraction, 0.06-0.22 and water up to 1 l. Mass ratio of mixture of surface-active substances to trisodium phosphate = 1:7. The proposed detergent can be used in technological processes, in part, in processing industry, automobile manufacture, machine engineering for treatment of metallic surface from oil, emulsion, lubricant pollutions. EFFECT: enhanced detergent capacity, providing preserving (protective) properties. 2 tbl
