Description

  The present invention relates to foamy hair styling cosmetics.

  One of the functions required of foamy styling agents is hairstyling. In order to impart hair styling properties, a film-forming polymer is generally used. However, when a film-forming polymer in an amount effective for hair styling is blended, there is a problem that even if the hair can be fixed and hair styling can be achieved, it becomes stiff and squeaky.

  In order to solve such problems, attempts have been made to make the film formed of the film-forming polymer flexible and improve the feeling of use. For example, a hair cosmetic composition containing an anionic polymer and silicones (see, for example, Patent Document 1), and a foam hair styling composition containing a film forming agent, silicones and an ether-based nonionic surfactant Product (for example, see Patent Document 2), aerosol composition (for example, see Patent Document 3) containing a film-forming polymer, a surfactant, and an oil, foam-form containing a film-forming resin and a sugar alcohol Hair cosmetics (see, for example, Patent Document 4) have been proposed.

  However, although such a trial can improve the stiffness and squeak, there is a drawback that stickiness occurs and the hair-styling property of the film-forming polymer is remarkably lowered. In addition, when hair is formed with a film-forming polymer, it forms a film on the hair and fixes it, so it has an excellent effect on the holding power of the hair that has been shaped, but due to its characteristics, it tries to re-hair the once broken hair Then, there is a problem that the formed film is peeled off, flaking occurs, and hair cannot be restyled.

After clinching the container, a method of filling a specified amount of propellant from the stem and attaching a button suitable for the stem can be exemplified.

  EXAMPLES Hereinafter, although this invention is demonstrated further in detail based on an Example, this invention is not limited only to these Examples. The blending amount represents “% by weight” unless otherwise specified. Moreover, the compounding quantity was converted into the pure part as each film forming polymer.

(Sample preparation 1)
The composition shown in Table 1 and Table 2 is mixed by a conventional method to prepare a stock solution. This stock solution is transferred to an aerosol container and charged with propellant (liquefied petroleum gas) at a weight ratio of stock solution / propellant = 90/10. Thus, each foam-like hairdressing cosmetic of Examples 1 to 8 and Comparative Examples 1 to 9 was prepared and subjected to the following evaluation. The results are shown in Tables 1 and 2.

(Test Example 1: Evaluation of hair styling and re-styling)
By applying 20 evaluation panels, each foamy hair styling cosmetic obtained in each example and each comparative example was evenly applied to the hair of a wig (Lesson Mannequin: manufactured by Eucalyptus Japan) to improve hair styling and re-styling. Sensory evaluation was performed according to the following evaluation criteria.

  The hair styling evaluation was carried out by performing the operation of squeezing the hair from the tip of the hair five times, and the styling shape that was clearly held in the formed style was evaluated as having good hair styling properties. In addition, the evaluation of re-styling was carried out by breaking the hair after standing for 30 minutes in the evaluation of the hair-styling, into a random pattern, and performing the same evaluation again.

(Test Example 2: Evaluation of usability)
Each foamy hair styling cosmetic obtained in each Example and each Comparative Example on a hair bundle (length 10 cm, width 0.8 cm, weight 1 g) left overnight under constant temperature and humidity of 23 ° C. and 60% humidity 0.5 g was applied and spread evenly with the fingertips. Again, it was left for 1 hour at a constant temperature and humidity of 23 ° C. and a humidity of 60%, and the evaluation panel 20 was subjected to sensory evaluations of wrinkles, creaking and stickiness according to the following evaluation criteria.

<Evaluation criteria for wrinkles>
◎: Reply if 16 or more out of 20 are not found ○: Reply if 11 to 15 out of 20 are not found △: Reply if 6 to 10 out of 20 are not found ×: Less than 5 out of 20 Reply

<Evaluation criteria for creaking>
◎: Reply if 16 or more out of 20 people do not respond ○: Reply if 11-15 out of 20 people do not respond △: Reply if 6-10 out of 20 people do not respond ×: Write out less than 5 out of 20 Reply

<Evaluation criteria for stickiness>
◎: Reply if 16 or more of 20 people are not sticky ○: Reply if 11-15 of 20 people are not sticky △: Reply if 6-10 of 20 people are not sticky ×: Less than 5 of 20 people Answer that it is not sticky

  From the results shown in Tables 1 and 2, the foam-type hair styling cosmetics of each example are stiff, squeaky, and sticky despite being excellent in hair styling properties as compared with those of each comparative example. I understand that it is not. Especially, it turns out that the foam-like hairdressing cosmetics of each Example has the effect excellent in the re-styling property.
