Embodiment 2
[0047] Embodiment 2: stability test
[0048] Test sample: the laundry detergent of embodiment 1-6, the laundry detergent of comparative example 1-5;
[0049] Test method: QB / T 1224-2012
[0050] Heat resistance: Keep it at (40±2)°C for 24 hours, and observe whether there is any obvious change from before the experiment after returning to room temperature;
[0051]Cold resistance: Keep it at (-5±2)°C for 24 hours, and observe whether there is any obvious change from before the experiment after returning to room temperature;
[0052] The test results are shown in Table 4;

[0056] As can be seen from Table 3, the soapberry laundry detergent of the comparative example will be unstable under hotter and colder environments, indicating that the adaptation of the sapinberry extract and various auxiliary materials cannot be used in hotter and colder environments. The environment remains stable, while the six embodiments of the present inven...
Embodiment 3
[0057] Embodiment 3: Suppleness performance test
[0058] Test sample: the laundry detergent of embodiment 1-6, the laundry detergent of comparative example 4-5, the super-concentrated laundry detergent A (surfactant content greater than 45%) of commercial source;
[0059] Experimental steps:
[0060] Pre-treatment: Cut the cloth used in the experiment into 8x8cm cloth pieces, soak them in 1% NaOH solution for 30 minutes, wash them with a washing machine for 35 minutes, centrifugal dehydration, and dry (105° C.).
[0061] Take by weighing each test sample and contrast laundry liquid 5g respectively, each use 250ppm hard water of 1000ml to rinse respectively in the jar of vertical decontamination machine respectively, put 6 cloth pieces in every cylinder, wash 20min with vertical decontamination machine ( 30°C, 120r / min), rinse once with 2L tap water, dry (105°C, 1h), cycle washing and drying steps 10 times.
[0062] After the cloth returned to room temperature, 10 profession...
