Description

  The present invention relates to a cosmetic for eyelashes and lashes at the hairline, and more particularly, a cosmetic for eyelashes and lashes at the hairline that has excellent hair-growth and gloss effects and realizes long and beautiful eyelashes with gloss and a method of using the same. About.

Many people have been suffering from hair loss and thinning since ancient times. Hair loss can be attributed to dandruff and sebum overgrowth, the effects of male hormones, scalp hardening due to poor blood circulation in the scalp, hair matrix damage, physical and mental disorders, malnutrition, etc. It has been found that these are due to single or combined action. Many hair restorers and hair nourishing agents have been developed to solve this problem, and many of them have been commercialized and put on the market. In particular, hair growth agents for scalp are mainly hair nourishing cosmetics containing a blood circulation promoting substance such as assembly to prevent hair loss due to poor blood circulation in the scalp.
On the other hand, unlike the hair on the eyelashes, the same type of mascara is routinely used for the purpose of impressing beautiful and attractive eyes. In the makeup act, a buller is used before applying mascara to give a curl effect, or a remover is included in cotton etc. to remove the applied mascara, but in any act, Physical damage is done to the eyelashes.
Many women are actually worried about eyelashes, and after confirming their worries by conducting a questionnaire, they often hear that their eyelashes are short, thin, or not shiny.
On the other hand, in recent years, there is a tendency to prefer healthy, shiny, long and beautiful eyelashes for beauty purposes.
(1) The luster imparted by the base makes the eyelashes healthier and thicker and blacker. (2) The effect of the base such as protecting the eyelashes from external factors is required.
In order to effectively apply a base containing these agents, it is not only used as a general mascara but also a compounded agent that can be uniformly applied to the eyelashes like eyeliner The effect can be expected more. Furthermore, if it can be applied evenly to the eyelashes, it will be glossy and thick, black and healthy eyelashes can be realized. At present, there are only a few cosmetics dedicated to eyelashes (Patent Document 1), which can be applied evenly and comfortably on the eyelashes, and have a healthy gloss finish and cuticle protection effect. There is no beauty serum, and a product with an applicator that can effectively apply the base has been awaited.

All compounding amounts are mass%. Moreover, the trade name: Isouri Liquid E of Ichimaru Falcos Co., Ltd. was used for the Tiso extract used in this example. However, in Examples, Examples 4 to 6 and Examples 9 to 18 are reference examples.

Example 1, Comparative Example 1 (hair growth effect test)
Eyelashes and eyelash hairline cosmetics were prepared according to the formulation shown in Table 1 below, and a hair growth effect test was conducted. The cosmetics for eyelashes of Example 1 and Comparative Example 1 were obtained by mixing and stirring all components other than potassium hydroxide at room temperature, adding potassium hydroxide, and increasing the viscosity.

(1) Hair growth effect test By 19 panelists (10 men, 9 women, of whom 2 women stopped the test on the way), the root of either the right or left eyelashes twice a day for 3 months A sample was applied to the sample, and after 1 month and 2 months from the start of the test, part of the upper and lower eyelashes was shaved, and the shaved site was photographed twice a week for about 2 months with a video microscope. Using the photographed image, the growth of new hair that had grown was measured over time to create a growth curve, and the length and growth rate were calculated and averaged.

For the calculation of the length and growth rate of the new hair, a growth curve of each eyelash was created, and the number was about 10 per eyelash, and a total of about 6000 were measured by 17 people. The calculation method is as follows.
(A) The average value of 5 points from the end of the measurement date was taken as “length”, and “eyelashes” that had not been fully extended on the last measurement day were excluded from the aggregation.
(B) The slope of the regression line up to 3/4 of the “length” was defined as the “growth rate”.

  The above method is illustrated in FIG. The results are shown in FIG. FIG. 2 is a comparison of left and right average values for each panel in the presence / absence of Titanium (Example 1, Comparative Example 1) (corresponding t-test).

  From the above results, in the human effect test, the growth rate of the eyelashes was significantly increased and the eyelashes tended to be long on the side where the formulation of the extract of diatomaceous earth was applied. It was thought that.

Examples 1-6, Comparative Examples 2-4 (Examination of base)
The cosmetics for the eyelashes and eyelashes are prepared with the formulation shown in Table 2 below. The refractive index of the coating agent, the stickiness of the base material, the film formability, the transparency of the resulting coating, and the glossiness are evaluated by the following evaluation methods. The appearance when applied to the eyelashes and the sagging of the preparation were evaluated. The results are shown in Table 2.

  The cosmetics of Examples 2 to 5 and Comparative Example 4 were prepared by adding components other than N, N′dimethylamide-2-acrylamide-2sodium methylpropanesulfonate-N, N′methylenebisacrylamide copolymer or hydroxyethyl cellulose to room temperature. After mixing and stirring, add N, N'dimethylamide-2-acrylamido-2-methylpropanesulfonate sodium-N, N'methylenebisacrylamide copolymer or hydroxyethylcellulose, and stir for 2 hours to increase the viscosity. Got in.

  The cosmetics of Example 6 and Comparative Example 2 were obtained by mixing and stirring ingredients other than phosphoric acid or potassium hydroxide at room temperature, adding phosphoric acid or potassium hydroxide, and increasing the viscosity. The cosmetic of Comparative Example 3 was obtained by mixing and stirring all ingredients at room temperature.

(Evaluation methods)
(1) Measurement of refractive index The refractive index of the coating agent at 20 ° C. was measured with a Refractometer RX5000α manufactured by ATAGO.

(2) Stickiness of base The stickiness of the base was measured with a transfer evaluation device. (See JP-A-11-281559)
The value after 150 seconds of rolling friction when a 10 g load was applied to a 20 μl sample was evaluated. This value corresponds to the stickiness when blinking, and was evaluated as follows.
○: 0.4 gf or less Δ: 0.4 to 0.8 gf
X: 0.8 gf or more

(3) Film formability:
The base material was applied to a rubber plate, and the film formability after drying at 37 ° C. for 2 hours was visually determined.

(4) Transparency of the film after drying:
The base was applied to a rubber plate and dried at 37 degrees for 2 hours, and the transparency of the resulting film was measured visually. A transparent one was marked with ◯, and a cloudy one was marked with ×.

(5) Gloss measurement:
The base was applied to a rubber plate, dried at 37 ° C. for 2 hours, and the reflectance when the light was applied to the rubber plate at 60 degrees was taken as the glossiness, and the measurement was performed and evaluated as follows.
○: 70 or more Δ: 50 to 70
X: Set to less than 50.

(6) How to see eyelashes The formulation was applied to the eyelashes, and those that looked thicker than the normal state in visual judgment were marked as ◯, and others were marked as x.

(7) Sacrifice of preparation The preparation was applied to the eyelids and eyelashes, and the sauce of the preparation was determined. Those that did not sag were rated as ◯, and those that sagged down were marked as x.

  As is apparent from Table 2, Examples 1 to 6 are preparations having no stickiness of the base, high gloss, and thick eyelashes. Comparative Example 2 was a formulation that did not contain a film agent having a refractive index of 1.41 or more, but the formulation had no glossiness but had a low glossiness and the eyelashes did not appear thick. Although the comparative example 3 is a prescription which does not contain a thickener, although the glossiness is high, the viscosity of the preparation was low, and it was a preparation with sagging. Although the comparative example 4 is a prescription with many thickeners, it was a sticky preparation which was hard to apply to the eyes.

Examples 7-8, comparative examples 5-6 (examination of brush)
