[0032] The preparation method of the seaweed extract is as follows: the seaweed after impurity removal is washed with a dilute acid solution with a pH of 2 to 4, minced, and ground and homogenized in a dilute acid solution with a pH of 2 to 4, and then The seaweed after pulping is matured and sterilized at a temperature of 121-135°C and a pressure of 1-5MPa for 0.5-2 hours. The degraded seaweed pulp is adjusted to pH 5.0-7.0 by adding alkali, ...

Embodiment 8

[0047] Stability detection of the product of Example 5 of the present invention:

[0048] 1. The pH value is 6.4.

[0049] 2. For heat resistance test, put the packaged samples into a constant temperature box (40±1)℃ for 24 hours, and there is no oil-water separation phenomenon after returning to room temperature.

[0050] 3. In the cold resistance test, put the fully packaged samples in the refrigerator at -5~-10℃ for 24 hours. After returning to room temperature, there is no phenomenon of delamination, thickening and discoloration.

[0051] 4. Centrifugation test, place the complete sample in a centrifuge at 2000 rpm for 30 minutes, without oil-water separation.

[0052] It can be seen that the cream prepared in Example 5 of the present invention has good stability.

Embodiment 9

[0053] Example 9 Clinical experiment and results of the present invention

[0054] Subjects: 40 volunteers aged 32 to 48 were randomly divided into 2 groups, the experimental group and the control group, 20 people in each group.

[0055] Experimental method: The testers in the test group performed cleansing treatment before going to bed every night, and then evenly applied the face cream prepared in Example 5 to the face, and the test period was one month. The testers in the control group performed cleansing treatment before going to bed every night, and then evenly applied the cream prepared in Example 1 to the face, and the test period was one month. Trial results are counted every 7 days, 15 days and 30 days.

[0056] Evaluation criteria: Effective means that the skin is moist and shiny, white and elastic, significantly reduced pigmentation, and fine lines are also improved; Invalid means that the skin texture has not changed from before the experiment; Generally, the skin...
