JP5048564B2 - Stick cosmetic - Google Patents

Description

  The present invention relates to a stick-shaped cosmetic, more specifically, because it softly collapses and adheres well to the skin and lips, it is excellent in coloring and moisturizing, has a fresh luster, has high temperature stability, and after molding Further, the present invention relates to a stick-shaped cosmetic having good releasability from a container filled with the cosmetic, a cap used for molding, a capsule, or the like.

  Conventionally, solid cosmetics such as stick cosmetics are required to have excellent quality such as non-stickiness, smoothness, evenness and evenness, excellent appearance quality, good moldability and shape retention strength. It was done. In order to obtain such a solid cosmetic, a technique in which a dextrin fatty acid ester and an alkyl-modified silicone wax are combined with a powder and an oil agent has been studied (for example, Patent Document 1).

  In addition, in order to obtain solid cosmetics that are easy to spread, hard to stick, have a glossy feel and are excellent in moldability, a combination of oils such as vegetable oils, esters and glycerides, oils such as hydrocarbons, and waxes is also available. It has been studied (for example, Patent Document 2).

  Furthermore, by combining polyethylene wax and oil agent that is hard to solidify by this to make a solid cosmetic with low hardness, this is filled into a specific container and made into a stick or stick shape, so that the usability of stick, gloss, moisture etc. A technique for realizing the persistence of the makeup effect has also been studied (for example, Patent Document 3).

  However, in the technique of Patent Document 1 that combines a dextrin fatty acid ester and an alkyl-modified silicone wax with a powder and an oil agent, and the technique of Patent Document 2 that combines an oil agent such as a vegetable oil, an ester, and a glyceride, an oil agent such as a hydrocarbon, and a wax. It was difficult to make a stick while maintaining a good feeling of use.

In addition, the above technique of filling a specific container with a low-hardness solid cosmetic into a stick or stick shape can maintain the cosmetic effect such as gloss and moisture, but the wax and oil are made of the same hydrocarbon. The spread was heavy and sometimes sticky. Further, in general, solid cosmetics with low hardness often cause sticking to the container sleeve portion and the tip capsule, and peeling, and there are many problems with so-called releasability.
JP 2007-161590 A JP 2006-151867 A JP 2006-248997 A

  Therefore, the present invention is characterized by excellent color development and moist feeling because it softly collapses and adheres to the skin and lips, and maintains a fresh luster, high-temperature stability and from the capsule attached to the container at the time of molding It is an object of the present invention to provide a stick-shaped cosmetic material that satisfies the good releasability at the same time.

  The viscosity of the hydrocarbon oil is a value measured using a Brookfield viscometer such as a single cylindrical rotational viscometer Bismetron (registered trademark) (manufactured by Shibaura System Co., Ltd.). Specifically, the viscosity value is measured as follows. First, a measurement sample is filled in a glass bottle having an outer diameter of 45 mm, an inner diameter of 38 mm, and a height of 82 mm so as not to generate an air space, covered, and left in a constant temperature bath at 20 ° C. for a whole day and night. The next day, with a single cylindrical rotational viscometer Bismetron (registered trademark) (manufactured by Shibaura System Co., Ltd.), using the attached No. 1-4 rotor, read the measured value after 1 minute at 0.3 to 30 rpm, The product of the multiplier is the viscosity value.

  The branched fatty acid and pentaerythritol ester of component (d) are obtained from branched fatty acid such as isooctanoic acid, isononanoic acid, isostearic acid and pentaerythritol. This ester of branched fatty acid and pentaerythritol moderately inhibits the crystal growth of the wax of the solid composition comprising the components (a), (b) and (c) and reduces the hardness at 35 ° C. to 30-120. By making it soft, it is possible to realize a fresh gloss with high durability. Specifically, to set the hardness at 35 ° C. to 30 to 120, by combining the component (d) with an appropriate blending ratio to the solid composition comprising the components (a), (b) and (c). It becomes possible. Specific examples of such branched fatty acid and pentaerythritol esters include pentaerythrityl tetraisooctanoate and pentaerythrityl tetraisostearate.

Example 1
Preparation of stick lipstick:
Stick-shaped lipsticks were produced according to the formulation shown in Table 1 and the manufacturing method shown below (Examples 1 to 4 and Comparative products 1 to 5). The hardness of each stick-shaped lipstick obtained was measured by the method shown below. In addition, by sensory evaluation, color development, moist feeling, lustrous luster persistence, high-temperature stability, and release properties from containers filled with cosmetics and caps used for molding were evaluated. The results are also shown in Table 1.

<Manufacturing method>
Ingredients 1 to 9 in Table 1 were dissolved at 100 ° C., and components 10 to 20 were added, uniformly mixed and dispersed, and defoamed. A lipstick container with a cap for molding (made of aluminum, caliber) 12 mm) was poured from the lower end of the lipstick container at 90 ° C. Thereafter, this was cooled to −20 ° C. and molded, and the cap was removed to produce a stick-shaped lipstick.

<Hardness measurement method>
A sample of the stick-shaped lipstick produced as described above was allowed to stand at 25 ° C. for 1 day. Using FUDOH RHEOMETER (manufactured by Fudo Kogyo Co., Ltd.), each sample was 35
A resistance value (gf) was measured when a needle having a diameter of 3 mm penetrated into a sample stored at 1 ° C. for 1 hour, and this value was taken as hardness.

<Evaluation method>
The stick-shaped lipstick produced as described above was evaluated based on the following evaluation criteria. Regarding the following evaluation items (i) to (c), each sample was subjected to a use test by 20 specialist panels. For each panel, ii) and b) observe the state of the coating film immediately after coating, and for c, observe the state after 3 hours have passed since coating. The average value was calculated from the total score of all the members and judged according to the following four-step criteria. A score was assigned according to the following absolute evaluation standard 1, and the average value was calculated from the total score of all the panels of each sample, and the determination was made according to the following four-step criteria. For each sample, each sample was stored at 50 ° C. for 1 month, and the following criteria 2 was evaluated by visually evaluating the presence or absence of perspiration, shape change, and color unevenness. Regarding e, each sample was drawn out to the end, and the appearance was visually evaluated according to the following criteria.

  The stick-like lipstick of the present invention has a characteristic that it is softly broken and has good coloration and moisturization because it has good adhesion to the skin and lips, has a feature of maintaining a fresh luster, high temperature stability, and further, after molding, the stick Since the lipstick shrunk moderately, it satisfied the good releasability from the container filled with cosmetics and the cap used for molding. On the other hand, Comparative Product 1 in which component (a) was not blended could not be evaluated because the hardness was too low to form a stick. Comparative product 2 containing no component (b) has low hardness and cannot be uniformly applied, so it has poor stability such as color development, moist feeling, lustrous luster, and shape change at high temperatures. Met. Moreover, the comparative product 3 which did not mix | blend a component (c) was not able to obtain a moist feeling and a fresh luster. In Comparative Product 4 in which component (d) was not blended, the releasability was deteriorated, and the hardness was high and the adhesion to the lips was deteriorated, so that coloring, moist feeling, and fresh gloss were impaired. Comparative product 5 in which cetyl isooctanoate was blended in place of component (d) had poor releasability such as peeling.
