Problems solved by technology

[0009] Aiming at the deficiencies of the facial mask in the prior art, the present invention provides a fast-gelling facial mask, which is a dry thin paper-like membrane with good toughness, does not add preservatives, and only needs a small amount of water It can be quickly transformed into a gel state, has good adhesion to the skin, and will not generate waste after use. It solves the separation of the mask matrix and the essence in the current facial mask, poor stability, the need to add an anti-corrosion system, and the mask matrix after use. Problems such as garbage generation and waste of functional ingredients need to be discarded

Embodiment 1

[0049] The degradation speed and mechanical strength of the fast-gelling facial mask are selected. The present invention needs to select an appropriate degree of cross-linking so that the fast-gelling facial mask can absorb liquid and degrade quickly when used, and then permeate and absorb after being converted into essence. At the same time, it has suitable mechanical strength and flexibility, which is convenient for transportation and has a good user experience.

[0050] 1. Sample preparation:

[0051] (1) Set up 6 experimental groups, add 40g of hyaluronic acid (H-HA) with a molecular weight of 3000kD and 0.4g of Ectoin into purified water, dissolve and mix for 2 hours until the solution is clear and free of visible foreign matter, H- The proportion of solid matter in the HA-Ectoin mixed system is 5%;

[0052] (2) Use NaOH to adjust the pH value of the above mixed system to 10, add 1,4-butanediol diglycidyl ether (BDDE), stir evenly, and cross-link for 6 h at a temperature...

Embodiment 2

[0069] The fast-gelling mask can quickly absorb liquid and degrade when used, and is used for moisturizing skin care. Five sets of masks were prepared for skin moisture testing.

[0070] 1. Sample preparation:

[0071] (1) Set up 5 groups of experimental samples, add 20g of hyaluronic acid (H-HA) with a molecular weight of 1000kD and 20g of ectoin (Ectoin) into the phosphate buffer for each group of experimental samples, dissolve and mix for 2 hours until the solution is clear Foreign matter is visible to the naked eye, and the proportion of solid matter in the H-HA-Ectoin mixed system is 0.5%;

[0072] (2) Use NaOH to adjust the pH value of the above mixed system to 12, add 1,4-butanediol diglycidyl ether, stir evenly, cross-link at 20°C for 8 h, and the mass ratio of H-HA to BDDE is 50: 1 (0.4000g BDDE);

[0073] (3) After cross-linking, use phosphate buffer to purify, take 100ml of the purified solution, and when the pH value is 7.5, the purification is complete, and H-HA...

Embodiment 3

[0084] The fast-gelling facial mask of the present invention has a suitable degree of cross-linking, can quickly absorb liquid and degrade when used, and can be transformed into an essence liquid to permeate and absorb. In this example, the rapid gelling facial mask of the present invention is compared with a double-layer porous biodegradable material coated with active molecules disclosed in our patent CN109316623A, and the difference in the state of liquid absorption and transformation between the two is observed.

[0085] 1. Test sample preparation:

[0086] (1) Add 40g of hyaluronic acid (H-HA) with a molecular weight of 1500kD and 40g of Ectoin into purified water, dissolve and mix for 2 hours until the solution is clear and free of visible foreign matter, solids in the H-HA-Ectoin mixed system Quality accounted for 2.5%;

[0087] (2) Use NaOH to adjust the pH value of the mixed system in step (1) to 10, add 1,4-butanediol diglycidyl ether (BDDE), stir evenly, cross-link...

Abstract

The invention discloses a facial mask capable of being quickly gelatinized as well as a preparation method and a use method of the facial mask, according to the invention, a cross-linked product of high molecular weight hyaluronic acid or salt thereof and ectoin is used as a facial mask matrix, and the facial mask matrix contains functional components. According to the facial mask, the cross-linked high-molecular-weight hyaluronic acid or salt thereof and the ectoin are used as the facial mask matrix, other skin-care functional components are embedded, physical support is not required to be provided by traditional non-woven fabrics and the like, the facial mask matrix is directly prepared from the functional components, the facial mask is a dry paper-like film, the system is stable, and noextra preservative is required to be added. The facial mask is good in flexibility and good in skin fitness, the facial mask can be rapidly converted into gel essence at an application part, the spray use amount is relatively small, and the gelation conversion time of the facial mask is short. In the degradation process, the high-molecular hyaluronic acid maintains the wet environment of the skinand plays a role in physical protection and slow release, the small-molecular ectoin is gradually released and continuously takes effect, and the functional components embedded in the mask matrix aredegraded and released along with the mask, so that multiple skin care effects are achieved.

Description

technical field [0001] The present invention relates to a fast-gelling facial mask and its preparation method and usage method, in particular to a fast-gelling facial mask that directly uses functional ingredients as the mask matrix, does not use traditional mask paper, is dry, and does not generate garbage. A gelled facial mask and methods of making and using the same. Background technique [0002] Mask is a carrier of beauty care products. The principle of mask is to use the time covered on the face to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, promote the secretion and metabolism of sweat glands, and make the skin oxygenated. The increase in the amount is beneficial for the skin to eliminate the products of epidermal cell metabolism and accumulated oily substances. There are many types of facial masks, including face masks, mud masks, gel masks, cream masks, etc. Among them, facial masks are the ...
