Abstract (en)

A scratch inhibiting agent for inhibiting the generation of scratches on the surtace of a siliceous inorganic product caused by an alkaline detergent comprising, as a main ingredient, at least one compound selected from the group consisting of (A) aliphatic hydroxydicarboxylic acids having a functional group ratio (OH/COOH) of 1.0 to 2.0 and the alkali metal salts thereof and (B) polycarboxylic acids having a molecular weight of 5000 to 20000 and the alkali metal salts thereof. This scratch inhibiting agent can effectively prevent the generation and expansion of scratches on the surfaces of the siliceous inorganic products without decreasing the washing power of aqueous alkaline solutions at a washing step.
