Abstract

A detergent composition, suitable for removing radioactive contaminations, comprises (a) a synthetic surface active agent, suitably an alkyl sulphate, (b) a water soluble polycarboxylic acid containing the group -N(CH2COOH)2, preferably ethylenediamine tetracetic acid or nitrilotriacetic acid ("ammonia triacetic acid"), (c) a water soluble nitrogen free polycarboxylic acid, such as oxalic, or more preferably citric, acid, and (d) an alkali metal or ammonium base, for example sodium hydroxide or carbonate, in an amount such that a buffer system is set up whereby an aqueous solution of the composition has a pH of 3-9. Usually a substance (e) which liberates fluoride ions in solution is also included, for example sodium fluoride. The composition may be produced in powder form by dissolving ingredients (a) to (d) in a little water at 50 DEG C., adding anhydrous sodium sulphate, and allowing the mixture to cool with stirring. A cream may be produced from a solution of the resulting powder by the addition of sodium alginate which may be wetted with methylated spirit. A scouring paste may be produced from such a cream by the incorporation of pumice powder and a liquid glyceride or, more suitably, glycerol.
