This invention relates to a method for preparing water-saving and environmentally friendly clothes washing agent. The washing agent uses chitin-probiotic bacteria to enhance the permeability and cleaning effect of active molecules of surfactants AES and APG, as well as the effect of their metabolic enzymes. The washing agent thus can improve the cleaning effect and reduce water consumption. Besides, the chitin-probiotic bacteria can accelerate the degradation of organic matters in wastewater, thus can purify wastewater and is environmentally friendly. |
