Description

Oil-based solid cosmetics

The present invention relates to an oily solid cosmetic.

Oily solid cosmetics, such as eye shadow, are a cosmetic formed by filling and molding a cosmetic base containing an oil agent as a main component, mixing a gelling agent, a powder component, etc., into a container such as a plate, and the method of use is simple. In addition, because it is excellent in portability, it is preferred by consumers. In oily solid cosmetics, since an oil is the main component, the translucency of the cosmetic film derived from the oil is easy to be obtained. For example, a technique combining (palmitic acid/octanoic acid) dextrin with a solid oil or bright powder (see Patent Document 1), an amino acid gelling agent and a volatile hydrocarbon oil, transparency of the base , a technique of oil-based makeup cosmetics imparting a fresh feel without stickiness (see Patent Document 2) has been proposed.

Japanese Patent Laid-Open No. 2009-286765 Japanese Patent Laid-Open No. 2013-126957

However, in the technique of Patent Document 1, although the shiny feeling is excellent, since a solid oil such as wax is used at room temperature, the transparency is low. , but there was a tendency to show oil droplets and water-based components (perspiration) under a high-temperature environment. From this background, there is a demand for an oil-based solid cosmetic that is excellent in makeup retention and transparency, is not sticky at the time of use, and is strong in high temperature stability.

Accordingly, an object of the present invention is to provide an oily solid cosmetic excellent in high temperature stability, a transparent cosmetic film, no stickiness, and excellent cosmetic retention.

In view of the above facts, the present inventors have addressed a phenomenon in which an oil gelled by an amino acid gelling agent separates from the gel structure of the amino acid gelling agent by molecular vibration of the oil under a high-temperature environment and sweats. By using a component that has lubricating properties to the oil agent without impairing the transparency of the topic, it was thought that perspiration of the oil agent could be suppressed without impairing the transparency. As a result of examining components having various lubrication properties, it was found that, by using a cellulose derivative, an oil-based solid cosmetic having excellent high-temperature stability was obtained without impairing transparency, while sweating at high temperature was suppressed. In addition, the present inventors, by containing an amino acid-based gelling agent and a cellulose derivative, improve cosmetic oils and fats, and become an oil-based solid cosmetic with less stickiness, and by adding more powder, the cosmetic retention and high-temperature stability of the oil-based solid cosmetic are more improved found, and completed the present invention.

(Manufacturing method)

A. Components (1) to (11) are heated to 130° C. and uniformly mixed and dissolved.

B. Add components (12) to (15) to A and mix uniformly at 100°C.

C. 2 g of the mixture of B was filled in a gold plate container (length 2.5 cm x width 2 cm x height 0.3 cm), and cooled to obtain an eye shadow.

(Evaluation items)

go. keep makeup

me. Transparency of the makeup film

All. no stickiness

la. high temperature stability

(Evaluation method 1)

For items A to C, use tests were performed by 20 expert panelists for each sample. Each panel uses the eye shadows of Examples 1 to 19 and Comparative Examples 1 to 3, and evaluates them in 7 steps on the following absolute evaluation criteria to give a rating, and calculates the average value from the sum of the ratings of all panel members for each sample. , was judged according to the following criteria. go. Regarding cosmetic maintenance, each sample was applied to the eyelids, and after the panel was allowed to live a normal life for 6 hours, whether the cosmetic film did not collapse due to tears, sweat, skin movement, etc. Regarding the transparency of the cosmetic film, whether the cosmetic film applied to the skin sufficiently felt the luminosity of the luminous powder and a sense of transparency was obtained. Regarding the absence of stickiness, it was evaluated whether or not stickiness was felt when each sample was applied to the skin.

△ (C: Normal) : 2 points or more - less than 3.5 points

×(D: bad) : less than 2 points

(Evaluation method 2)

Regarding the evaluation items of (d), the state after storing each sample at 50°C for 2 weeks is evaluated by visual observation whether there is no expression (perspiration) of oil droplets or aqueous components, and the following criteria are met. judged by

<Judgment Criteria>

(Judgment): (Evaluation)

(A): Sweat was not observed at all.

○(B): There is some sweating at high temperature, but it disappears when returning to room temperature.

Δ(C): Perspiration is observed at high temperature and disappears when returned to room temperature, but sweat marks remain on the surface.

x (D): Remarkable sweating was observed at high temperature, and sweating did not disappear even if it returned to room temperature.

As is clear from the results shown in the table, the eye shadows of Examples 1 to 19 were good in all of the cosmetic oils and fats, transparency, no stickiness, and high temperature stability. In particular, Examples 1-3 and 6 were the eyeshadows which were especially excellent in all evaluation. On the other hand, Comparative Example 1 in which the component (B) was not blended and Comparative Example 2 in which silicic anhydride was used instead was not satisfactory in terms of transparency and no stickiness and stability at high temperature. Comparative Example 3 using 12-hydroxystearic acid and Comparative Example 4 using (palmitic acid/octanoic acid) dextrin were not particularly satisfactory in terms of lack of cosmetic oil, stickiness, and high temperature stability.
