め現在では殆ど使用されなくなった。2. Description of the Related Art Detergent builders improve the washing effect of surfactants and soaps mainly by chelating calcium and magnesium ions in water due to their chelating performance. Conventionally, sodium tripolyphosphate has been mainly used as a detergent builder. Sodium tripolyphosphate has excellent performance as a builder for detergents, such as chelating performance.However, because it contains phosphorus, the wastewater after washing containing it is discharged as it is, which contributes to the eutrophication of rivers and lakes. Becomes As a result, it has hardly been used at present.

が現状である。[0005] In place of sodium tripolyphosphate, various organic carboxylic acid-based builders such as an inorganic ion exchanger such as zeolite and nitrilotriacetic acid are used.
Or being researched. However, zeolite is inferior to sodium tripolyphosphate in performance as a detergent builder, and is poorly soluble in water, so it is unsuitable for formulating a liquid detergent, and has a drawback of sticking to a washing machine even when used as a powder detergent. is there. In addition, various organic carboxylic acid-based builders are being studied, but chelating performance,
At present, it has been pointed out that there are problems such as the effect of enhancing detergency and economy.

利である。The compound represented by the general formula (1) used in the present invention has excellent chelating performance,
As it is extremely water-soluble, there is no need to worry about sticking to the washing machine,
It is suitable as a builder for liquid detergents and powder detergents. The compound can be easily and inexpensively synthesized by reacting epoxysuccinic acid with iminodiacetic acid or glycine, and can be used as an alkali metal salt such as sodium or potassium, an ammonium salt, or a mixture thereof. In the cleaning composition of the present invention, the compounding ratio of the compound represented by the general formula (1) is in the range of 1 to 40% by weight. If less than this, the chelating performance of the entire detergent composition is low,
It is economically disadvantageous to have more than necessary. As the surfactant used in the present invention, conventionally known various anionic surfactants, nonionic surfactants,
And cationic surfactants and mixtures thereof. For example, alkyl sulfate, alkyl benzene sulfate, alkyl benzene sulfonate, paraffin sulfonate, olefin sulfonate, alkoxylated alcohol, alkyl phenol, alkyl phenol sulfate, fatty acid sulfonate, fatty acid ester sulfonate and the like can be used. In the cleaning composition of the present invention, the mixing ratio of the surfactant is 1 to 40.
