[0039] The molecular weight of the hyaluronic acid and / or hyaluronate used in the film-forming agent composition provided by the present invention should not be too small or too large. If the molecular weight is too small, the molecular chain is too short, the intermolecular force is too weak, and it is difficult to form a continuous film structure. If the molecular weight is too large, the molecular chain is too long, the intermolecular force is too strong, and it will be too viscous to form a continuous film.

[0040] In some embodiments, the hyaluronate in the film-forming agent composition is selected from at least one of sodium hyaluronate, potassium hyaluronate, and calcium hyaluronate.

[0041] In some embodiments, the polyol in the film-forming agent composition is selected from at least one of glycerol, propylene glycol, and butylene glycol.

[0042] The present invention also aims to provide a method for preparing a film-forming agent composition. The content of each component of the raw materials involved below is calculated by weight percentage of the film-forming agent composition. The preparation method comprises the following steps:

[0043] Adding 0.2-2% of hyaluronic acid and / or hyaluronate to 15-40% of polyol and dispersing them to obtain a first mixture;

[0044] Adding the first batch of deionized water to the first mixture and stirring evenly to obtain a first mixed solution;

[0045] adding 0.5-2% of gluconolactone and / or lactobionolactone into the second batch of deionized water for dissolution to obtain a second mixed solution;

[0046] Mixing the first mixed solution and the second mixed solution uniformly to obtain the film-forming agent composition;

[0047] The deionized water content of the first batch accounts for 60-80% of the total weight of the deionized water; the deionized water content of the second batch accounts for 20-40% of the total weight of the deionized water.

[0048] The film-forming agent composition of the present invention is used as a film-forming agent in the preparation of a makeup-fixing product in the field of cosmetics.

[0049] The film-forming agent composition of the present invention is used as a film-forming agent in the preparation of sunscreen products in the cosmetics field.

[0050] The film-forming agent composition of the present invention is used as a film-forming agent in the preparation of medicines in the medical field.

[0051] Embodiment 1:

[0052] The film-forming agent composition is prepared. The content of the following components is calculated as a percentage by weight of the film-forming agent composition. The specific steps for preparing the film-forming agent composition are as follows:

[0053] 0.5% of hyaluronic acid with a molecular weight of 100W is added to 20% of glycerol and stirred to disperse evenly to obtain a first mixture. The first batch of deionized water is added to the first mixture and stirred to obtain a first mixed solution. 0.5% of gluconolactone is added to the second batch of deionized water for dissolution to obtain a second mixed solution.

[0072] As shown in Table 2, Table 2 is the test results of various performance indicators of the film-forming agent compositions of Examples 1-24 and Comparative Examples 1-4.

[0073] Table 2:

[0074]

[0075]

[0076]

[0077] It can be seen from the test result data in Table 2 that the film-forming agent composition provided in the embodiments of the present invention is obtained by adding an appropriate amount of polyol, gluconolactone and / or lactobionic acid lactone to an aqueous solution of active substances hyaluronic acid and / or hyaluronate; since polyol, gluconolactone and / or lactobionic acid lactone can form hydrogen bonds with the active substances hyaluronic acid and hyaluronate, the three mixed together can form a complex hydrogen bond network, which can greatly improve the flexibility of the film-forming agent composition, and the film-forming effect is good. At the same time, the film-forming agent composition provided in the embodiments of the present invention has good ductility, spreadability, wear resistance, smoothness, glossiness, as well as skin-fitting and sticky feeling. The score value of each performance item is basically above 6 points, and the comprehensive score is as high as 60 points or more. The comprehensive score of the performance items of the film-forming agent composition provided in some embodiments exceeds 70 points, and the comprehensive performance of film-forming is excellent. It can be used as a film-forming agent in cosmetics and skin care products in the cosmetics field, and in medicines in the medical field. See Figure 1 and Figure 2 , Figure 1 Schematic diagram of the flat film-forming effect of the film-forming agent composition prepared in Example 1 of the present invention, Figure 2 Schematic diagram of the flat film-forming effect of the film-forming agent composition prepared in Example 16 of the present invention; Figure 3 It is a schematic diagram of the flat film-forming effect of the film-forming agent composition prepared in Example 18 of the present invention.

[0078] The composition prepared in Comparative Example 1 is a simple hyaluronic acid aqueous solution, which has a poor film-forming effect and the obtained transparent film is brittle and thin; Figure 4 , Figure 4 Schematic diagram of the film-forming effect of the composition prepared in comparative example 1 of the present invention; the composition prepared in comparative example 3 is a composition in which gluconolactone is added to a hyaluronic acid aqueous solution, and its film-forming effect is extremely poor; from the score values ​​of each performance item in Table 1, it can be seen that the film-forming performance of the compositions corresponding to comparative examples 1 and 3 is poor. The compositions prepared in comparative examples 2 and 4 are a composition in which polyols are added to a hyaluronic acid aqueous solution; the obtained compositions cannot form a film when spread on a smooth table, see Figure 5 , Figure 5 It is a schematic diagram of the flat film-forming effect of the composition prepared in Comparative Example 2 of the present invention. The difference between the composition prepared in Comparative Example 5 and Example 1 is that low molecular weight hyaluronic acid is used; the difference between the composition prepared in Comparative Example 6 and Example 11 is that low molecular weight hyaluronic acid and low molecular weight sodium hyaluronate are used. From the score values ​​of each performance item in Table 1, it can be seen that the film-forming properties of the compositions corresponding to Comparative Examples 5 and 6 are poor, and the scores of ductility, smoothness, glossiness, skin-fitting feel, wear resistance, and stickiness are relatively low. This is because when the molecular weight of hyaluronic acid and sodium hyaluronate is too small, the molecular chain is too short, and the intermolecular force is relatively weak, making it difficult to form a good film structure.

[0079] In summary, the film-forming agent composition provided by the present invention comprises the following components by weight percentage: 0.2-2% hyaluronic acid and / or hyaluronate, 15-40% polyol, 0.5-2% gluconolactone and / or lactobionic acid lactone, and deionized water to make up the balance. That is, the film-forming agent composition provided by the present invention is obtained by adding an appropriate amount of polyol, gluconolactone and / or lactobionic acid lactone to an aqueous solution of active substance hyaluronic acid and / or hyaluronate; since polyol, gluconolactone and / or lactobionic acid lactone can form hydrogen bonds with active substance hyaluronic acid and hyaluronate, the three can be mixed together to form a complex hydrogen bond network, thereby greatly improving the flexibility of the film-forming agent composition, and the film-forming effect is good, and the comprehensive performance of the film-forming is excellent, and it can be used as a film-forming agent in cosmetics and skin care products in the cosmetics field, as well as in medicines in the medical field.

[0080] Those skilled in the art may combine and associate different embodiments or examples and features of different embodiments or examples described in this specification without mutual contradiction.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
