Abstract: An antimicrobial detergent composition includes the following components by mass percent: 0.1-10% of a polyester-polyether polymer, 0.01-2% of an antimicrobial agent with a halogenated phenol structure, 10-50% of a surfactant and a solvent. A 1% deionized water solution of the detergent composition has a pH value of 7.0-9.0. In the present invention, by introducing the polyester-polyether polymer into the composition, the deposition efficiency of the antimicrobial agent with the halogenated phenol structure on a fabric can be improved, a solubilization effect of the surfactant in a detergent can be reduced, and therefore, a antimicrobial effect is achieved.

Abstract: The present invention relates to packaging material/matrix and methods of making such packaging material/matrix for slow or extended release of at least one active volatile compound(s). Provided are methods and compositions for a polymer matrix incorporating at least one active volatile compound (for example 1-methylcyclopropene or 1-MCP) and the polymer matrix is synthesized by polycondensation. This polymer matrix can slowly release the active volatile compound after contacting with a solvent (for example moisture). Also provided is the use of such polymer matrix to prolong the shelf-life of fruits and vegetables.
