Title (EN) CLEANING SOLUTION COMPRISING A MIX OF POLYOXYALKYLENE NONIONIC SURFACTANTS FOR CLEANING METAL SURFACES
(FR) SOLUTION DE NETTOYAGE COMPRENANT UN MÉLANGE DE TENSIOACTIFS NON IONIQUES DE POLYOXYALKYLÈNE POUR LE NETTOYAGE DE SURFACES MÉTALLIQUES
Abstract:
(EN) Cleaning solution for cleaning and / or wetting metal surfaces, comprising: - at least one acid, - a first surfactant, which is an alkyl-poly(ethyleneglycol-co-propyleneglycol)-ether having a cloud point of ≤ 25°C, - a second surfactant, which is selected from the group consisting of i) an alkyl-poly(ethyleneglycol-co-propyleneglycol)-ether having a cloud point of ≥ 30°C, ii) an alkyl-polyethyleneglycol-ether having a cloud point of ≥ 45°C wherein the cloud points are determined according to European Standard EN 1890:2006, item 8.2 of German Version, with the modification that 10 wt% H2SO4 is used as solvent and that the concentration of the surfactant is 1000 mg/L.
(FR) L'invention concerne une solution de nettoyage pour nettoyer et/ou humidifier des surfaces métalliques, comprenant : - au moins un acide, - un premier tensioactif, qui est un alkyl-poly(éthylèneglycol-co-propylèneglycol)-éther ayant un point de trouble ≤ 25 °C,- un second tensioactif, qui est choisi dans le groupe constitué par i) un alkyl-poly(éthylèneglycol-co-propylèneglycol)-éther ayant un point de trouble ≥ 30 °C, ii) un alkyl-polyéthylèneglycol-éther ayant un point de trouble ≥ 45 °C, les points de trouble étant déterminés selon la norme européenne EN 1890:2006, point 8.2 de la version allemande, avec pour modifications que 10 % en poids de H2SO4 sont utilisés en tant que solvant et que la concentration du tensioactif est de 1 000 mg/l.
