On January 4, 2019, Wang, Songying; Qiu, Zhenming; Huang, Liang; Jiang, Dan published a patent.Formula: C4H6ClNOS The title of the patent was Application of polymer as protease stabilizer in detergents and detergent composition. And the patent contained the following:
Title polymer is an ethoxylated polyethyleneimine. Thus, deionized water was added to the configuration tank; next, 10 weight% of ethoxylated fatty alc. sulfate, 4 weight% of alpha-olefin sulfonate, 7 weight% of ethoxylated fatty alc. 9 and 0.6 weight% of potassium hydroxide were admixed therein, then, protease, 0.05 weight% of 1,2-benzisothiazolin-3-one, 0.05 weight% of 2-methylisothiazolin-3-one and 5-chloro-2-methylisothiazolin-3-one and 1 weight% of polyacrylic acid were mixed thereto, heated, and stirred to obtain the title detergent composition The experimental process involved the reaction of 2-Methylisothiazol-3(2H)-one hydrochloride(cas: 26172-54-3).Formula: C4H6ClNOS
The Article related to polymer protease stabilizer detergent composition, Surface Active Agents and Detergents: Cleaning Compositions and other aspects.Formula: C4H6ClNOS
