Description
Technical Field
The invention relates to the field of skin care products, and particularly relates to a mask with a long-acting moisturizing effect and a preparation method thereof.
Background
Facial masks are an important part of daily skin care products of people, and the moisturizing facial masks always occupy the primary position of facial mask products. Most of the moisturizing facial masks are used for directly supplementing skin moisture, maintaining the water content of stratum corneum, promoting the repair of skin barrier function and achieving the moisturizing effect.
The moisturizing effect of the moisturizing facial mask in the current market mainly depends on the following two ways: (1) the humectant in the product can combine moisture to introduce moisture into the crystalline structure of skin, and the components mainly comprise urea, trehalose, etc.; (2) the skin conditioner such as plant extract is added to improve physiological function of skin cells, thereby increasing skin moisture.
However, the various small molecule moisture-keeping components in these products only provide instant moisture-keeping effect, and the moisture content of skin is rapidly reduced after the mask cloth is removed, so that the long-term moisture-keeping effect cannot be achieved. The micromolecular humectant such as trehalose and sodium pyrrolidone carboxylate can rapidly permeate through the horny layer and be absorbed by the skin, the moisturizing effect of the micromolecular humectant can not be exerted on the horny layer for a long time, and the micromolecular humectant can not be continuously supplemented, so that the long-acting moisturizing effect of the product can not be achieved.
Based on the above problems, how to improve the moisturizing performance and the moisturizing efficiency of the small-molecule moisturizing agent in the mask product so that the moisturizing effect of the mask product is more durable and efficient becomes a technical problem to be solved by the technical personnel in the field.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide the moisturizing facial mask, which is formed by compounding three macromolecular carriers and simultaneously loads a micromolecular moisturizing agent, so that the micromolecular moisturizing agent is slowly released and efficiently utilized, and the moisturizing effect of the facial mask is effectively improved.
In order to realize the purpose, the invention adopts the following technical scheme:

According to the invention, three macromolecules of the polyglutamic acid sodium, the carrageen crispa and the sodium hyaluronate are compounded to form a spatial network structure and form a film, the macromolecular structure bears micromolecular moisturizers such as trehalose and amino acid, and the slow release effect is generated on the micromolecular moisturizers, so that the mask has the efficacy of long-acting moisturizing.
According to some preferred embodiments of the present invention, the ingredients and amounts of the phase C complex moisturizer are as shown in the following table:
| serial number | Name of raw materials | Addition amount (wt%) |
| 1 | Water (W) | TO100 |
| 2 | Hyaluronic acid sodium salt | 0.01-5.00 |

According to some embodiments of the present invention, the process for preparing the phase C composite moisturizer comprises the following steps:
(1) adding sodium polyglutamate, Chondrus crispus and sodium hyaluronate into glycerol, stirring and dispersing uniformly, adding into water, stirring, and heating to 70-90 deg.C to dissolve to obtain a first solution;
(2) adding L-serine, L-proline and L-glutamic acid into the first solution obtained in the step (1) to dissolve, adding a pH regulator to regulate the pH to 4.5-5.5, and stirring to obtain a second solution;
(3) stirring and dissolving betaine, sodium pyrrolidone carboxylate, trehalose and allantoin, and adding the mixture into the second solution obtained in the step (2);
(4) cooling to below 40 deg.C, adding urea and antiseptic, stirring, filtering, and discharging.
The inventor researches and finds that the heating temperature of the composite humectant is very important to the preparation process. When the heating temperature is lower than 60 ℃, the stability, uniformity and the like of the obtained composite humectant are poor, and when the heating temperature is higher than 70 ℃, the stability and the product state are good, and the stability, uniformity, fluidity, moldability and other properties of the composite humectant have great influence on the performance of the carrier, and the heating temperature is preferably higher than 70 ℃ in the preparation process of the composite humectant. In addition, although the solution is soluble at 95 ℃, on the one hand, the solution is prone to yellowing when heated at high temperatures for a long time, and on the other hand, the high temperatures cause energy waste for industrial production. Therefore, the preparation temperature of the compound humectant is preferably controlled to be 70-90 ℃.
Furthermore, the molecular weight selection of the macromolecular raw materials of the invention, namely the sodium polyglutamate, the sodium hyaluronate and the carrageen crispus, is very important for the film forming and slow release effects of the humectant.

The product prepared with the larger molecular weight has better lubrication and skin feel experience, and the film forming property of the product with the larger molecular weight is better, so that the moisturizing effect of the product is more favorable. According to repeated experimental screening, researchers of the invention determine that the molecular weight of the macromolecular carrier substance of the composite humectant is as follows: the polyglutamic acid sodium is more than or equal to 50 ten thousand Da, the Phragmites communis is more than or equal to 80 ten thousand Da and the hyaluronic acid sodium is more than or equal to 5 ten thousand Da.
