Abstract
The present invention refers to an aqueous composition comprising one or more amphoteric, organic polynitrogen-compounds having at least 3 nitrogen atoms contained in the molecule in the form of an amine and/or amide and one or more types of inorganic nanoparticles, a concentrate comprising said composition and to a method for treating and/or cleaning a surface which uses said composition.
Claims16
An aqueous composition comprising
- an amphoteric, organic amine or amide having at least 3 nitrogen atoms and formed by reacting polyethylenimine and polyacrylic acid;
- and
- an inorganic nanoparticle selected from the group consisting of amorphous silicon dioxide, silica sols, fumed silica, and mixtures thereof, and
- sodiummethylglycine diacetate;
- wherein the organic amine or amide and the inorganic nanoparticle are present in a 1:1 weight ratio and wherein the composition forms a removable coating when applied to a surface.
