Embodiment 1

[0030] Preparation of MIL-101 matrix:

[0031] Weigh 1.08 g of ferric chloride and 0.66 g of terephthalic acid into a 60 mL airtight glass bottle, and add 40 mL of N,N-diformamide to it for ultrasonication to dissolve the solid to obtain a brownish-yellow solution. The system was placed in an oven and heated at 110°C for 24 hours. After the reaction, the reaction mixture was centrifuged at high speed, and the brown supernatant was discarded to obtain an orange solid, which was washed several times with deionized water. Place in a desiccator and dry at room temperature for 24 hours.

[0032] The solid obtained above was solvent-exchanged with ethanol at a frequency of 4 times a day for three days, and the obtained solid was air-dried at room temperature. Grind and sieve to obtain the cleansing mask MIL-101 matrix.

[0033] Preparation of ZIF-11 preservative:

[0034] Weigh 0.12 g of benzimidazole and place it in a reaction flask, add 4.8 g of ethanol into the reaction flask...

Embodiment 2

[0036] Cytotoxicity experiment of porous framework materials: Hela and 3T3 cells in exponential phase were collected, and the cell concentration was adjusted to 4×10 4 ~5×10 4 / mL. The experimental wells and control wells were 100 μL of cell suspension, and the blank control wells were the same volume of culture medium. After culturing overnight, the experimental wells were replaced with porous framework material solutions of different concentrations, with 5 to 6 replicate wells for each concentration, and the same volume of culture solution was added to the control wells and blank control wells, and placed in CO 2 After culturing in a constant temperature incubator for 4 hours, suck off the supernatant and wash with PBS 1-2 times. Add 100 μL of culture medium and 10 μL of MTT solution, and continue to incubate for 3 hours. After 3 hours, the supernatant was sucked away, 100 μL of DMSO was added to each well, and placed on a desktop constant temperature shaker at 37°C and 8...

[0043] Test experiment of the adsorption performance of porous frame material on grease:

[0044] Weigh 0.2 g of dried porous framework material into a sealed sample bottle, and vacuumize for 7 hours at 110° C. to remove the solvent in the pores of the material. Add 10 mL of oil into the sample vial with a syringe, stir at room temperature for 20 minutes, filter and wash the adsorbed oil with a 0.22 μm hydrophobic needle filter, and quantitatively detect it. as attached figure 1 As shown, the grease adsorption performance of most porous framework materials is much greater than that of traditional porous materials. Among them, MIL-101-CH with larger specific surface area and larger pore size 3 、MIL-101-NH 2 , MIL-101 and PCN-333, showed stronger oil adsorption capacity than other porous frame materials. In addition, after the structural modification of MIL-101, because the newly introduced functional groups enhanced the interaction between the material and the oil, the obta...

Abstract

The invention discloses application of porous frame materials in masks. To solve the problems that a traditional mask matrix is high in irritation and poor in cleaning capacity, an added homogeneous preservative easily causes skin allergy and inflammation, and active matter can not be fully utilized, the high adsorbability and antibacterial property of the porous frame materials and the property of slowly releasing active ingredients are creatively utilized to solve the problems in the existing mask technology. Meanwhile, through many experiments and long-term exploration, screening criteria of the porous frame materials for different kinds of masks are established, and the interaction mechanism of the porous frame materials and guest molecules is studied according to the material structures.

Description

technical field [0001] The invention relates to the fields of material chemistry and skin care products, in particular to the application of porous frame materials in facial masks. Background technique [0002] With the improvement of living standards, people pay more and more attention to skin maintenance and care. As a convenient and effective skin care product, facial mask is loved by many beauty lovers. From the perspective of the function of the mask, it can be divided into a cleansing mask and a functional mask. Among them, the cleansing mask is mainly through the adsorption of kaolin, volcanic clay, diatomaceous earth and other substrates to absorb and remove excess oil on the facial skin and pollutants in the pores, so as to achieve a cleansing effect on the skin. However, the currently used cleansing mask matrix cannot achieve deep cleansing of the skin due to its limited adsorption capacity and strong irritation, which will easily lead to problems such as pore bl...
