Abstract: Based on the basic idea of Green Chemistry, a water-based cleaning agent with very simple formula, alkalescence and high detergency was successfully developed via organic built-up of appropriate surfactants and emulsifier without addition of any acid and base. Based on orthogonal experiments and formula optimization experiments, the optimal recipe was decided as follows:8.0% alkyl polyglucoside, 3.5% fatty alcohol-polyoxyethylene ether, 3.5% polyoxyethylene nonyl phenol ethers and 2.0% coconut oil glycolamide in a tap water solution. The cleaning agent has a nearly neutral pH of 7.5 and very high decontamination rate of 99.3%. The cleaning agent and its diluent solutions for 2 and 4 times have higher decontamination rate than that of the commercial multi-purpose cleaning agent and their corresponding diluent solutions. The cleaning agent has the advantages of cheap industrial raw materials, very simple recipe, excellent cleaning performance, and thus has widespread application prospect.
