摘要： Provided are scale-inhibition compositions comprising (a) a first acrylic acid polymer having an average molecular weight of about 3000 to about 6000; (b) a second acrylic acid polymer having an average molecular weight of about 6000 to about 10000; (c) an aminocarboxylic acid selected from methylglycine diacetic acid (MGDA), glutamic acid diacetic acid (GLDA), diethylene triamine pentaacetic acid (DTPA), hydroxyethyl ethylene diamine triacetic acid (HEDTA), ethylenediaminetetraacetic acid (EDTA), and a combination thereof; and (d) a phosphonic acid selected from 1-hydroxyethane 1,1-diphosphonic acid (HEDP), amino tris(methylenephosphonic acid) (ATMP), ethylenediamine tetra(methylene phosphonic acid) (EDTMP), tetramethylenediamine tetra(methylene phosphonic acid) (TDTMP), hexamethylenediamine tetra(methylene phosphonic acid) (HDTMP), diethylenetriamine penta(methylene phosphonic acid) (DTPMP), and a combination thereof. The scale-inhibition compositions may be useful in machine ware washing detergents and formulations.
