Problems solved by technology

[0004] However, there are two problems with the combination of traditional matrix + mask liquid: first, the ingredients of vitamins, trace elements, and active biological factors in the mask liquid are prone to oxidation and degradation in liquid state. Loss during storage will definitely affect product quality and user experience
Second, when the mask stays on the skin surface for a long time and dries up, it sucks back the moisture in the skin and causes skin damage

Abstract

The invention belongs to the technical field of mask materials and discloses a gradual-dissolution type hydrating mask and a preparation method of the gradual-dissolution type hydrating mask. The preparation method of the gradual-dissolution type hydrating mask comprises the steps that firstly, a mixed aqueous solution of starch acetate and starch sugar is mixed with a hydrating active ingredient aqueous solution or a mixed aqueous solution of a hydrating active ingredient and disodium glycyrrhetate, the mixture is evenly dispersed, and then a spinning solution is obtained; and secondly, electrostatic spinning is conducted on the spinning solution, collection is conducted through a collecting device, and then the gradual-dissolution type hydrating mask is obtained. The gradual-dissolution type hydrating mask is characterized by having dissolvability, high absorbability and being natural, environmentally friendly and healthy. The difference between a traditional mask and the gradual-dissolution type hydrating mask is that activated matter is carried by fiber, mask liquid and a matrix are integrated, and the gradual-dissolution type hydrating mask is in a dried fibrous membrane form normally; in this way, the risks of oxidation, degradation and microbiological contamination in the liquid state are lowered, and the gradual-dissolution type hydrating mask is convenient to transport and store. Use of the gradual-dissolution type hydrating mask is simplified, and it is only needed to wet the mask before use. The permeation capacity to the skin of the gradual-dissolution type hydrating mask is improved because of the high specific surface area of the nanometer fiber mask.

Description

technical field [0001] The invention belongs to the technical field of facial mask materials, in particular to a gradually dissolving moisturizing facial mask and a preparation method thereof. Background technique [0002] Today, facial masks are widely used as cosmetic products that have a cosmetic effect on the skin of the face and the like. The principle of the facial mask is to apply a thick layer of dressings with different functions and ingredients on the face to block the contact between the skin and the air. When this layer of dressing is tightly attached to the skin, it will increase the temperature of the skin by inhibiting the secretion of sebum and the evaporation of sweat; after the temperature of the skin rises, blood circulation will be promoted, and the nutrients that penetrate into the skin will be deeper between the cells. spread out more widely. [0003] Traditional mask materials generally include blended cloth, silk, cotton, polyester, etc. Then the f...
