Abstract

To provide a method having an excellent effect of curling eyelashes and capable of keeping the curled shape for a long time.SOLUTION: A method for keeping a curled shape of eyelashes includes applying, to eyelashes, eyelash cosmetics containing one or more selected from (A) hydroxymonocarboxylic acid, hydroxydicarboxylic acid, aromatic sulfonic acid and salts thereof.SELECTED DRAWING: None

Description

  The present invention relates to a method for maintaining the curl shape of a heel.

  The mascara is applied to the eyelashes or the eyelashes that have been combed upward with the eyelash curler, and is further used by curling the eyelashes by repeatedly applying the mascara liquid by lifting the eyelashes with a brush. After application, it is completed by drying at room temperature. After completion, the shape of the eyelashes is fixed with a mascara film, and the curled state is maintained.

Conventionally, various vaginal cosmetics such as mascara have been studied which have high curl effect and curl sustaining effect.
For example, Patent Document 1 discloses an eyelash cosmetic containing a film forming agent including a copolymer having at least one of methyl methacrylate, methacrylic acid, or acrylic acid and a monomer unit of urethane acrylate. It is described that it is excellent in the makeup effect that curls the wrinkles upward and makes the eyes stand out. Patent Document 2 discloses an oil-in-water cosmetic for salmon containing an alkyl acrylate / vinyl acetate copolymer emulsion, an alkyl acrylate copolymer emulsion, carbon black, a polyhydric alcohol, and a water-soluble film-forming agent. It is described that it is excellent in luster, blackness, cleansing property and storage stability that impress the eyes.

Examples 1-21 and Comparative Examples 1-2
A cosmetic liquid for acupuncture having the composition shown in Table 1 was produced by uniformly stirring and mixing each component, and the curl angle when applied to a vaginal sample was evaluated. The results are also shown in Table 1.

(Curl angle evaluation method)
(1) Straight hair (8-9 mm in length) was fixed to a PET sheet with a tape to prepare a wrinkle sample. (The curl angle is 0 degree.)
(2) Each salmon serum was applied to the salmon sample and dried (8 hours). The vaginal essence was applied 10 times at a rate of once per second using a vaginal brush (total 0.05 mg).
(3) The soot sample was washed (10 seconds with warm water).
(4) The wrinkle sample was curled with a wrinkle curler. The curl angle was set to 45 degrees by measuring the angle from the horizontal when the base and tip of the heel sample were connected by a straight line.
(5) The curl angle immediately after the curl angle evaluation O / W emulsified mascara having the composition shown in Table 2 was applied to the wrinkle sample curled at a curl angle of 45 degrees was measured. The O / W emulsified mascara was applied 15 times (total 0.1 mg) at a rate of once per second.
This curl angle is applied to the original straight hair by modifying the hair with the effect of the cosmetic liquid for wrinkles of the present invention. The curl shape continues to be maintained without returning to the straight hair.
