Description

The present invention has a high curling effect immediately after applying an eyelash cosmetic to the eyelashes, maintains the curling effect even after washing, has excellent curl restoration properties, and is a W / O emulsified type or O / W emulsified type. To provide a cosmetic for eyelashes of any type, such as an emulsified type such as a mold or an aqueous type, which has a high curling effect, a long-lasting curling effect, and a high curl restoring property.

Eyelash cosmetics, typified by mascara, have cosmetic effects such as curling the eyelashes upward and making the eyelashes look thicker and longer, thereby making the eyes clearer. Conventionally, various dosage forms such as W/O emulsified type, O/W emulsified type, and water-based type are known as eyelash cosmetics. On the other hand, the W/O emulsified type has a long-lasting curling effect, but in some cases a special remover is used to remove makeup. The O/W emulsified type and water-based type can be easily removed, but in some cases the durability of the curl is poor.
In Patent Document 1, by adding dextrin fatty acid ester to the water-based type, the persistence is enhanced as much as possible. Patent Document 2 proposes that by adding a nonionic surfactant having a specific HLB to an emulsified type, it can be easily removed while maintaining its persistence. However, in any type of eyelashes, the curl may not last after the mascara is removed, and the eyelashes may return to the original state of less curled. Therefore, in some cases, it is necessary to curl the eyelashes every day. In Patent Document 3, in order to maintain the curl of the eyelashes, a specific amino acid is blended to enhance the durability of the curl after mascara is removed. However, in some cases, only a specific emulsified composition was found to be effective.

Become.

The effect of the eyelash cosmetic of the present invention will be described in more detail with reference to the following examples, but the present invention is not limited to these examples. In the examples, unless otherwise specified, ingredients used were those purchased from Fujifilm Wako Pure Chemical Industries, Ltd.

Eyelash cosmetics having compositions shown in Tables 1 to 3 were prepared according to a conventional method to obtain eyelash cosmetics described in Examples 1 to 6 and Comparative Examples 1 to 6. The numbers in the composition indicate weight percent of pure content. The obtained cosmetic for eyelashes was evaluated as follows. The results are shown in Tables 1-3.

Evaluation method (1) Curl restorability after washing (hair test)
A small amount of human hair (Beaulux Co., Ltd., hair strand 5, black hair 100% straightened at the root) was taken to pass through a mascara brush, and the length was adjusted to 15 cm. The center portion of the untreated hair (blank) was attached to a pure bending tester (Kato Tech Co., Ltd., KESFB2-S type) without slack, and the bending properties (hardness and recovery force) were measured. Measurement was performed 5 times. Then, using a mascara brush (outer diameter 5.5 mm, nylon (4 mil), squeegee diameter 3.4 mm), the eyelash cosmetic was applied 10 times to the hair, and the temperature and humidity were constant at 20 ° C. and 60%. Dry in a humid chamber for 8 hours. The hair was washed with a commercially available oil cleansing agent and then washed with lukewarm water. The washed hair was dried for 12 hours in a constant temperature and humidity chamber with a room temperature of 20° C. and a humidity of 60%, and then the bending properties were measured under the same conditions as above.
Calculation method of stiffness change rate:
Measure the bending stress (Y) when reciprocating the curvature (X) range of -2.0 to +2.0 cm ^-1 at a change rate of 0.5 cm ^-1 · s ^-1 , and the obtained bending stress - X on the curvature curve: bending properties were measured from the slope of the curve between 0.5 and 1.0 cm ^-1 and -0.5 and -1.0 cm ^-1 . Here, the bending motion from the origin to X: ±2.0 cm ^-1 is defined as "push", and the bending motion from X: ±2.0 cm ^-1 to the origin is defined as "return".
In addition, stiffness is used as an index of curl restoration, and an improvement in stiffness indicates that curl restoration of the eyelashes has improved after application of the eyelash cosmetic and removal of the eyelash cosmetic. The stiffness change rate was calculated from the formula (1) using the average value (n=5) of the slopes of the push/return curves before or after application of the eyelash cosmetic. However, in formula (1), α is the push before processing, β is the push after processing, γ is the return before processing, and η is the return after processing, and each value is the average value of the slope of the curve. .
Regarding the method for evaluating stiffness, first, the rate of change (σ/%) in stiffness after treatment with the eyelash cosmetic was calculated from the formula (1). After that, the ratio of the stiffness change rate after treatment with the cosmetic for evaluation eyelashes to the standard product was calculated. The higher the value, the higher the curl restorability.
Formula (1) σ [%] = {(η/β) ÷ (γ/α)} × 100

(2) Curl effect immediately after application (usage evaluation)
The eyelash cosmetic was applied to the eyelashes 30 times, and the curling effect was evaluated. The evaluation was performed by 10 women as a professional panel, and the women who applied the product evaluated the curling effect of their own eyelashes.
⊚: More than 9 out of 10 evaluated that the curling effect after application was high.
A: 6 to 8 out of 10 evaluated that the curling effect after application was high.
Good: 3 to 5 out of 10 evaluated that the curling effect after application was high.
x: 2 or less out of 10 evaluated that the curling effect after application was high.

(3) Persistence of curl after washing (usage evaluation)
The eyelash cosmetic was applied to the eyelashes 30 times, washed after 8 hours, and the curling effect was evaluated. The evaluation was performed by 10 women as a professional panel, and the women who applied the product evaluated the curling effect of their own eyelashes.
⊚: 9 or more out of 10 evaluated that the curling effect after washing was high.
A: 6 to 8 out of 10 evaluated that the curling effect after washing was high.
◯: 3 to 5 out of 10 evaluated that the curling effect after washing was high.
x: 2 or less out of 10 evaluated that the curling effect after washing was high.
