Abstract
This invention relates to demulsifying cleaning preparations having a prolonged surface-wetting effect which contain the following components: (a) builders/complexing agents in an amount of from 0.5 to 10% by weight, (b) one or more alkanolamines in an amount of from 20 to 60% by weight, (c) one or more nonionic surfactants in an amount of from 1 to 15% by weight and (d) water in an amount which, with components (a), (b) and (c), adds up to 100% by weight. The cleaning preparations are suitable for cleaning and degreasing lacquered or non-lacquered vehicle surfaces, engines, floors and walls of workshops at temperatures as low as room temperature with demulsification of the oily or fatty soil removed.
Claims13
A demulsifying cleaning preparation free of organic solvent and having a prolonged surface-wetting effect consisting essentially of;
- (a) a builder/complexing agent in an amount of from about 0.5 to about 10% by weight,
- (b) at least one alkanolamine in an amount of from about 20 to about 60% by weight,
- (c) at least one nonionic surfactant in a quantity of from 1 to 15% by weight, said nonionic surfactant being selected from the group consisting of the condensation products of n-octanol with 4 moles of ethylene oxide, i-octanol with 4 moles of ethylene oxide, n-octanol with 2 moles of propylene oxide and 5 to 6 moles of ethylene oxide and i-octanol with 2 moles of propylene oxide and 5 to 6 moles of ethylene oxide, and
- (d) water in an amount which, with components (a), (b) and (c), adds up to 100% by weight, all weights being based on the weight of said cleaning preparation, and as optional constituents;
- (e) a solution promoter in an amount of from about 1 to about 10% by weight,
- (f) a corrosion inhibitor for lightweight metals in an amount from about 0.15 to about 0.25% by weight said corrosion inhibitor comprising phosphoric acid,
- (g) a corrosion inhibitor for nonferrous metals in an amount of from about 0.2 to about 0.4% by weight said corrosion inhibitor coprising tolyl triazole, and
- (h) a perfume or dye in an amount of from about 0 to about 1% by weight.
A demulsifying cleaning preparation free of organic solvent and having a prolonged surface-wetting effect consisting essentially of;
- (a) a builder/complexing agent selected from the group consisting of ethylenediamine tetracetic acid, nitrilotriacetic acid, diethylenetriamine pentacetic acid, N-(2-hydroxyethyl)-ethylene diamine triacetic acid, and water soluble alkali metal salts thereof in an amount of from about 0.5 to about 10% by weight;
- (b) at least one alkanolamine selected from the group consisting of diethanolamine, triethanolamine, diisopropanolamine, and triisopropanolamine in an amount of from about 20 to about 60% by weight;
- (c) at least one nonionic surfactant selected from the group consisting of the condensation products of n-octanol with 4 moles of ethylene oxide, i-octanol with 4 moles of ethylene oxide, n-octanol with 2 moles of propylene oxide and 5 to 6 moles of ethylene oxide, and i-octanol with 2 moles of propylene oxide and 5 to 6 moles of ethylene oxide in a quantity of from about 1 to about 15% by weight;
- and
- (d) water in an amount which, with components (a), (b) and (c), adds up to 100% by weight, all weights being based on the weight of said cleaning preparation.
