Problems solved by technology

[0005] In the existing skin care products, there are relatively few types of Lagerstroemia indica extracts as active ingredients. It is necessary to provide a new skin care formulation to broaden the application range of Lagerstroemia indica extracts and meet the needs of consumers
In addition, the existing facial mask development focuses more on the extraction of skin care active ingredients and the compounding effect between ingredients, and pays little attention to the mask matrix

Embodiment 1

[0044] The preparation of embodiment 1 crape myrtle polyphenol extract

[0045] (1) Crude polyphenol extraction

[0046] Weigh 10g of dried Lagerstroemia grandiflora leaf coarse powder and place it in a beaker, then add ethanol with a volume fraction of 70% according to the solid-liquid ratio of 1g:10mL, and extract twice with ultrasonic waves at 20°C; centrifuge the extract, The supernatants were combined, concentrated under reduced pressure, and then the concentrated solution was freeze-dried to obtain the crude polyphenol extract of Lagerstroemia sinensis, which was stored in a refrigerator at 4°C until use;

[0047] (2) Purification

[0048] ①Macroporous resin pretreatment: Soak AB-8 macroporous resin in absolute ethanol for 24 hours to fully swell the resin and remove surface impurities, then rinse with 95% ethanol solution until no turbidity appears, and then wash with water until No alcohol smell, then soak in 5% HCl solution and 5% NaOH solution for 2 hours respectivel...

Embodiment 2

[0051] The preparation of embodiment 2 Tremella polysaccharide extract

[0052] (1) Remove the roots of fresh white fungus and put them in an oven, dry them at 65°C, crush them, soak them in absolute ethanol for 12 hours, filter and dry them, and set them aside;

[0053] (2) Take 10 g of white fungus obtained in step (1), add distilled water according to the liquid-to-material ratio of 1 g: 100 mL, adjust the pH to 8.8, put it in a water bath at 90 ° C for 1.5 h after ultrasonication for 30 min, centrifuge, and take the supernatant; Repeat the extraction once according to the above steps, combine the supernatants, and spin evaporate to 1 / 5 of the original volume to obtain the material;

[0054] (3) Add absolute ethanol 80 times its volume to the material obtained in step (2), stand still for 12 hours, centrifuge, take the solid, and dry to obtain Tremella polysaccharide extract.

Embodiment 3

[0055] The preparation of embodiment 3 supramolecular hydrogel matrix

[0056] Dissolve the guar gum hydroxypropyl trimethyl ammonium chloride in the formula amount in water to make an aqueous solution with a mass volume concentration of 6%, then heat it to 55°C, and slowly add the pre-dissolved mass volume concentration of 3% The phytic acid aqueous solution was reacted for 2 hours under stirring, and methylisothiazolinone was added, stirred evenly, reacted for 30 minutes, cooled to room temperature, and dried to obtain a supramolecular hydrogel matrix.

Abstract

The invention relates to a moisturizing, anti-ageing and skin-whitening gel mask and a preparation method thereof. The mask comprises the following preparation raw materials: a macromolecular wettingagent, a micromolecular wetting agent, a tremella polysaccharide extract, a lagerstroemia speciosa polyphenol extract, diguanosine tetraphosphate, polyglycerol-2, a supermolecular hydrogel matrix anddeionized water. The supermolecular hydrogel matrix is prepared from the following raw materials: guar hydroxypropyl trimethylammonium chloride, phytic acid and methylisothiazolinone. The mask provided by the invention replaces the conventionally used thickening agents such as xanthan gum and sodium alginate by using the self-made supermolecular hydrogel matrix, has excellent antibacterial property, has viscosity lower than that of the conventional thickening agent, is easy to coat, does not stick and pull fine hair when needing to be removed, avoids skin discomfort and improves the comfortable sensation of users; the mask has remarkable moisturizing, anti-ageing and skin-whitening effects, and avoids pore blockage and avoids phenomena of blackhead, acne and enlarged pore after long-time use.
