Embodiment 1～3 and comparative example 1
[0172] Compositions A to D of Examples 1 to 3 and Comparative Example 1 were prepared according to Table 1. The rheological yield stress and viscosity of each system were tested, and the results are shown in Table 1.
[0173] Table 1 has yield stress low viscosity liquid detergent composition
[0174]
[0175] In Examples 1 to 3 and Comparative Example 1, the types and contents of surfactants in each system are the same, and the difference between the systems lies in the electrolyte content, resulting in a large difference in the rheological yield stress of each system. Due to the presence of sodium chloride and sodium citrate in 1 to 3, the system has a certain yield stress uniformly, while the comparative example has no yield stress; at the same time, the systems of Examples 1 to 3 have a certain yield stress in 20s -1 At a certain shear rate, each system maintains a viscosity lower than 1000mpa·s. Maintaining relatively high yield stress at relatively low viscosity, th...
Embodiment 4～7 and comparative example 2～5
[0177] According to Table 2, the compositions E-L of Examples 4-7 and Comparative Examples 2-5 were prepared. The rheological yield stress and viscosity of each system were tested, and the results are shown in Table 2.

Embodiment 8～10 and comparative example 6
[0188] According to Table 3, the compositions M-P of Examples 8-10 and Comparative Example 6 were prepared. The rheological yield stress and viscosity of each system were tested. In addition, a decontamination test was also carried out on a low-viscosity liquid detergent composition with a certain yield stress. The results are shown in Table 3.
[0189] Table 3 has yield stress low viscosity liquid detergent composition
[0190]
[0191]
[0192] The difference between Examples 8-10 and Comparative Example 6 is that the compositions M, N and O of Examples contain a certain amount of electrolytes, while the composition P of Comparative Example 6 does not contain electrolytes. As can be seen from the results in Table 3, the cleaning performance of compositions M, N and O containing a certain amount of electrolyte (including carbon black stained cloth, protein stained cloth and sebum stained cloth) is better than composition P. In the compositions M, N and O, as the electr...
