Description

Lipstick and its manufacturing method

The present invention relates to a lipstick formed with a thin film on the surface of the lipstick and a manufacturing method thereof. More specifically, at least one component selected from polymers capable of forming a film among polymers commonly used as raw materials for cosmetics such as cellulose derivatives, polyvinylpyrrolidone or derivatives thereof, and acrylic polymers, and one selected from cosmetic oils as a plasticizer. The present invention relates to a lipstick and a method for producing the same, wherein a solution in which at least one component is dissolved in a volatile solvent is sprayed onto the lipstick to be uniformly applied, followed by volatilization of the solvent to form a thin film.

In general, lipstick must be classified into usability, appearance, and stability. Usability should be excellent in feeling of use, color effect after use, persistence and moisturizing effect, and appearance appearance and appearance gloss should be good. In terms of stability, there should be no sweating, discoloration and discoloration. However, the usability, appearance gloss and sweating among these have given a considerable number of limitations in the manufacture of conventional lipsticks. That is, it is very difficult to manufacture a lipstick that satisfies all of these conditions, and in most cases, these conditions are mutually opposite conditions, so if you are satisfied with the feeling of use, sweating or appearance gloss often becomes a problem. There has been a problem with the appearance gloss. Therefore, the most preferred is a lipstick with excellent usability and appearance and no sweating.

Sweating is a common phenomenon of lipstick. The solid crystal lattice structure formed by the wax and oil contained in the lipstick maintains a stable parallelism at low temperatures in winter or spring, but the wax and oil are increased when the temperature rises and the daily crossover increases in summer. The parallel state of the oil becomes unstable and the expansion rate of the oil becomes larger, and the oil is separated into the surface of the lipstick and oil droplets are formed on the surface of the lipstick as if it is sweating. It is known to make. Therefore, in order to suppress such sweating, conventionally, the wax content or the chemical structure of the wax or oil is used to form a strong network structure of the stick to obtain a structural effect by reducing the amount of colorant and hygroscopicity. Methods of limiting the use of oils and the like have been known. However, these methods are intended to minimize the expression of the lipstick, but can not be completely suppressed, moreover, these methods are a significant constraint in obtaining the excellent usability of the lipstick as it places great restrictions on the selection and use of the lipstick raw material.

On the other hand, to improve the appearance gloss of the lipstick, there is a known method of using a material with high gloss or applying silicone oil to the surface of the lipstick, but the initial gloss is excellent when the silicone oil is coated on the surface of the lipstick, but the gloss persists for a long time. Rather after storage, there is a problem of significantly reducing the gloss.

The present inventors found that a film made of a polymer and a plasticizer capable of forming a film on a lipstick with high sweating and poor appearance gloss was formed on the surface of the lipstick, thereby suppressing the sweating of the lipstick and increasing the appearance gloss. The present invention has been completed.

Therefore, an object of the present invention is to suppress the sweating of the lipstick with excellent usability to increase the stability at high temperature and to give the lipstick an excellent gloss while imparting this gloss while maintaining the surface of the solid or solid film that sustains the gloss for a long time. It is to provide a lipstick and a method of manufacturing the same.

The reason why the lipstick produced in the present invention has such excellent characteristics is that the film produced by the polymer and the plasticizer blocks the contact with the outside of the lipstick contents to suppress moisture absorption in the outside air and because of the solid physical property of the film itself. While it is possible to physically suppress the sweating of the oil separated from the lipstick, sweating is also suppressed by the dense network structure of the polymer film, and the film itself has excellent gloss and the film is stable, so the excellent gloss lasts for a long time. Will be.

The components of the mixed solution made to form the film in the present invention is a known material, the polymer for film formation is polymers such as cellulose derivative, polyvinylpyrrolidone or derivatives thereof, acrylic polymer, and the like as silicone polymers. Cosmetic oil-based components such as fatty acids, fatty acid esters and fatty alcohols are used, and volatile pure solvents such as lower alcohols, lower ethers and lower esters such as ethyl alcohol, isopropyl alcohol, ethyl ether and ethyl acetate are used as the solvent. One or more components selected from the above polymers and one or more components selected from plasticizers were uniformly applied to the surface of the lip tip after dissolving the solution in one or more components of the volatile solvent to volatilize the solvent to form a thin film having excellent gloss. Make lipstick. However, if the formed film is too thick or the film strength is too high, the antiperspirant effect may be better or the debris of the film may remain on the lips or the use area of the lipstick without being applied well under the influence of the strong film during the initial use of the lipstick. . Therefore, in order to eliminate these drawbacks, the concentration of the film-forming polymer must be properly adjusted to the concentration of the plasticizer, and the selection of the solvent is also important. The concentration of the polymer is preferably 1-5% and the concentration of the plasticizer is 1-5%. Hereinafter, the present invention will be described in detail by the following examples.

Test methods in Examples and Comparative Examples according to the present invention are as follows.

Coating method of film forming agent

The composition according to the following example of the film-forming agent was sprayed sufficiently to prevent the contents from flowing on the surface of the lipstick and uniformly applied to the surface, and left at room temperature for 1 hour to completely volatilize the solvent.

result

TABLE 1

The sweating phenomenon was severe enough that the oils sweated together in Examples 1 and 2 (Comparative Examples) and Examples 3 and 4 were aggregated together, and in the case of appearance gloss, the initial gloss was excellent in Examples 3 and 4 However, after 60 days, the gloss is considerably deteriorated and worsened. Therefore, when the surface of the lipstick is coated with only polydimethylsiloxane, the initial gloss is excellent, but the glossiness is deteriorated significantly as it is stored for a long time.

TABLE 2

Example 1 and 2 (comparative example) showed a very severe sweating phenomenon, but it can be seen that the coating of the film on the surface as in Example 5-14, the antiperspirant effect is quite excellent. In addition, the gloss of the film is excellent, and in the case of Example 5-14, the appearance gloss is extremely excellent as compared with Examples 1 and 2 (Comparative Examples), and the gloss of the film is stable, and thus the gloss persistence is also excellent.
