  A scratch inhibiting agent for inhibiting the generation of scratches on the surface 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.

  一种用于抑制碱性洗涤剂在硅质无机产品表面产生划痕的划痕抑制剂，其主要成分包括至少一种选自以下组别的化合物：(A)官能团比（OH/ COOH）为 1.0 至 2.0 的脂肪族羟基二羧酸及其碱金属盐；(B)分子量为 5000 至 20000 的多羧酸及其碱金属盐。 这种划痕抑制剂可有效防止硅质无机产品表面划痕的产生和扩大，而不会降低碱性水溶液在洗涤步骤中的洗涤力。
