preparation example Construction
[0029] 1, the preparation method of biochar of the present invention is as follows:
[0030] The organic biomass is crushed and passed through a 200-mesh sieve; the sieved particles are vacuum-dried at 75°C for one day; under the protection of an inert gas, carbonization is carried out at 220°C and 35bar pressure for 30 minutes, and then immersed in cold water to cool down to stop further carbonization. Finally, dry for 2 hours to ensure that the finished biochar is obtained after complete drying.
[0031] 2, the preparation method of the okra extract of the present invention is as follows:
[0032] Pick fresh okra, cut off the roots of okra and clean them, cut into sections and soak in boiling water for 5 minutes, vacuum filter to obtain the filtrate, and concentrate the filtrate under reduced pressure at 55°C until the volume becomes 1 / 3 of the original volume, then concentrate to obtain The okra extract.
Embodiment approach
[0049] The implementation plan is as follows: select 30 people in each group to carry out the experiment. The experimenter uses the corresponding product to use the corresponding test product every night between 22-24 o'clock. The trial period of each sample is one month. On the 30th day, the experimenter conducts self-evaluation on the effect of adsorbing heavy metals; During the entire experiment, no other skin care products should be used during the experiment.
[0050] Using the clinical evaluation of skin quality, the test results of adsorption of heavy metals are shown in Table 3 below.
[0051] table 3
[0052]
[0053] As can be seen from Table 3, for the problems of facial allergies and long spots caused by heavy metals, the ingredients of the embodiment have obvious improvement effect, while in the comparative example, due to the lack of one of fulcic acid, biochar, and okra extract or more, resulting in insignificant effect, or even no effect, it can be seen that...
