A synergistic disinfectant composition comprises a C1-8 organic acid, an amino acid based surfactant, an anionic surfactant, and a stabilizing agent. The C1-8 organic acid may include two or more types of the C1-8 organic acids with at least one of the C1-8 organic acids is alpha hydroxyl acid. The disinfectant composition has an antimicrobial activity of log reduction of at least 2 under Biocidal Product Registration (BPR) standard EN13727, EN1276, EN13624 or EN1499, and/or the EPA standard that applies the '-' issued by the Organisation for Economic Co-operation and Development (OECD). In addition, the disinfectant composition may be stable during storage and retain their antimicrobial activity after at least one month at 40° C. When desired, the synergistic disinfectant composition may further comprise an oxidizing agent.

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.
