Abstract (en)

[origin: WO9323522A1] Storage-stable, pumpable, alkaline cleaning concentrates are composed of aqueous dispersions based on alkali metal hydroxides, in which are dispersed alkali metal silicates and/or alkali metal phosphates as alkaline builders, as well as non ionic and/or anionic surfactants and if required other builders and/or complexing agents and/or active or auxiliary substances known per se. These cleaning concentrates are characterized in that they contain as stabilizers a combination of (a) polyacrylic acid and/or alkali metal polyacrylates and (b) glycerine and/or polyglycerine.
