Antimicrobial detergent composition comprising a polyester-polyether polymer and a halogenated phenol antimicrobial agent mixture

An antimicrobial detergent composition, comprising the following components by mass percent:

• a compound formed by 0.1-10% of a polyester-polyether polymer and 0.01-2% of an antimicrobial agent with a halogenated phenol structure;
• 10-50% of a surfactant;
• and
• a solvent,
• wherein a 1% deionized water solution of the antimicrobial detergent composition has a pH value of 7.0-9.0,
• wherein the compound is formed by pre-mixing the polyester-polyether polymer and the antimicrobial agent with the halogenated phenol structure in the following steps:
• a) dissolving the antimicrobial agent with the halogenated phenol structure into the solvent to prepare a solution A with a concentration of 20-40 wt %;
• b) dissolving the polyester-polyether polymer into the solvent to prepare a solution B with a concentration of 40-70 wt %;
• c) conducting stirring mixing on the solution A and the solution B to obtain a uniform solution;
• and
• d) slowly adding water into the uniform solution obtained in step c) for stirring to obtain a uniform compound solution,
• wherein in step a) and step b), the solvent is one or more selected from the group consisting of isopropanol, 1,2-propanediol, dipropylene glycol, diethylene glycol butyl ether and ethylene glycol;
• wherein the polyester-polyether polymer comprises a fabric-friendly segment formed by a condensation reaction of a terephthalate and a diol, and a hydrophilic segment comprising a segment consisting of ethylene oxide repeating units;
• wherein the antimicrobial agent is one or more selected from the group consisting of 5-chloro-2-(2,4-dichlorophenoxy) phenol, chlorodimethylphenol and 5-chloro-2-(4-chlorophenoxy) phenol.
