Description

The present invention relates to hair cosmetics.

In recent years, the hairstyles that consumers want have changed. For this reason, the performance required for hair styling products is different from that of fixing hair with a conventional adhesive polymer or film-forming polymer, while maintaining a natural cohesiveness and giving the finished hair a soft and natural feel. It has changed to.

To meet these demands, there are non-aqueous hair cosmetics, especially products commonly referred to as hair oils. However, women in recent years, in particular, do not have an unpleasant presence such as squeaky hair or oiliness, feel like bare hair, and have a natural appearance without a feeling of bunch, but finger passage. I'm looking for a well-organized hair styling product. Therefore, due to the oil contained in the hair oil, when the hair is applied to the entire hair at the time of application, and after the application, the oil continues to slip on the oil for a while, leaving an unnatural feeling of hair bundles, the appearance of the hair, and the appearance of the hair. There are increasing calls for improvement of problems such as heavy touch and stickiness.

In order to solve the above problem in hair oil, for example, Patent Document 1 discloses a hair oil in which a polyether-modified silicone having a specific structure, a volatile oil and ethanol are used in combination. The document discloses that this hair oil eliminates the oiliness immediately after application, has good hair compatibility, and improves dryness over time.

Further, Patent Document 2 discloses a specific isoparaffin-based hydrocarbon and a quick-drying hair oil containing a specific hydrocarbon. The document discloses that when this quick-drying hair oil is applied to wet hair, the time for drying the hair can be shortened and the dry hair is given a conditioning effect.

In Patent Document 3, a non-aqueous hair care composition containing a large amount of base oil composed of isoparaffin, mineral oil, volatile silicone compound and a mixture thereof, and containing a hydrophilic material such as pantenol and a specific liquid alcohol in a constant ratio. The thing is disclosed. The document discloses that the composition can dissolve a hydrophilic material in a base oil to maintain a transparent appearance while reducing the greasy feel.

However, the hair oils of Patent Documents 1 to 3 can impart a cohesive feeling and a conditioning effect after drying when applied to wet hair after washing, but when applied to dry hair, they spread wet. There was a problem that the cohesiveness after drying and the goodness of finger passage were insufficient because the hair was insufficient. Further, if a sufficient amount is applied so that the hair can be uniformly applied to the entire hair, there is a problem that the weight and the feeling of hair bundle remain after drying. Further, in Patent Document 1, problems still remain regarding the unnatural feeling of hair bundles and weight caused by volatile oil, and in Patent Documents 2 and 3, the evaporation rate of water in wet hair after washing is increased. Even if it was formed, there was room for improvement due to the strong unnatural feel due to the volatile oil content between the time it was applied to dry hair and the time it dried.

The present inventors considered that the problem of the above-mentioned non-aqueous hair cosmetics was mainly that it took time for the volatile oil to volatilize after application, and as a result of examination, a specific lipophilic solvent and a lower alcohol were used. At a specific ratio, the polymer and other ingredients contained in the hair cosmetics wet and spread very quickly, thinly and evenly, and as a result, immediately after application and after drying, without giving the hair an unnatural feeling of hair bundle or weight. Both were found to have a good feel.

However, when this hair cosmetic absorbs water vapor in the air during use or storage, there may be a problem that separation or cloudiness occurs.

Therefore, according to the present invention, when applied to dry hair, the hair dries immediately after application, does not give a squeaky feeling or oiliness, and after drying, the hair can be naturally bundled without forming a hair bundle, and further used. The present invention relates to hair cosmetics that do not easily deteriorate in appearance even when water is mixed in or during storage.

The present inventors have added a branched saturated or linear unsaturated aliphatic alcohol or an ether thereof to a non-aqueous hair cosmetic containing a specific lipophilic solvent and a lower alcohol in a specific ratio during use or storage. The invention was completed by finding that the appearance is less likely to deteriorate even when water is mixed in the mixture, and the feel after application is also improved.

That is, the present invention contains the following components (A) to (C), the mass ratio (A) / (B) of the component (A) to the component (B) is 0.8 or more and 99 or less, and the water content. Provides hair cosmetics in which is less than 5% by mass.

[Examples 1 to 12 and Comparative Examples 1 to 4]
The hair cosmetics shown in Table 1 were prepared by a conventional method, and water resistance and high temperature stability were evaluated according to the following methods and criteria.

"Water resistance evaluation"
As a model when water was mixed, water was added to the hair cosmetics shown in Table 1, and the maximum amount of water added that did not cause cloudiness or separation was investigated.
1. 1. 10 g of the hair cosmetics shown in Table 1 was weighed into a No. 6 screw tube (manufactured by Maruem Co., Ltd.).
2. While stirring with a stirrer, 25 μL of ion-exchanged water was added dropwise using a micropipette (Research Plus V 3120, manufactured by Eppendorf).
3. After each dropping, the mixture was stirred for 1 minute, and when the water was uniformly dissolved, the next 25 μL was added.
Repeat 4.2 and 3 to make the water cloudy without being completely dissolved, or to finish when the solution separates, and the total amount of water added (μL) up to just before the separation is the maximum water resistance amount per 10 g of hair cosmetics. And said.

"High temperature stability evaluation"
40 mL of the hair cosmetics shown in Table 3 was weighed in a 50 mL glass bottle (wide-mouth standard bottle PS-NO.6; Sansho Co., Ltd.), covered and sealed. This was allowed to stand in a constant temperature bath at 50 ° C. for 2 hours. After that, it was taken out from the constant temperature bath, and the state of the hair cosmetic in the glass bottle was visually observed. The evaluation was performed according to the following criteria.
⊚: Not separated ○: White turbid, but returns to a uniform solution when returned to room temperature ×: White turbid or separated and does not return to a uniform solution even when shaken after returning to room temperature

In addition, the hair cosmetics shown in Table 1, which had a good water resistance test, were sprayed into a pump spray container manufactured by Yoshino Seisakusho Co., Ltd. (a sprayer having an average particle size of 60 μm when the hair cosmetics of Examples and Comparative Examples were sprayed. Was used), and the performance was evaluated according to the following methods and criteria.

(Evaluation hair bundle)
A hair bundle with a length of 30 cm and a weight of 8 g was prepared from Japanese weak habit hair having no history of chemical treatment. After wetting the hair bundle with tap water at 40 ° C. for 30 seconds, 3 g of Kao Success Medicated Shampoo h was applied, and the hair bundle was washed with lather for 30 seconds and rinsed with tap water at 40 ° C. for 30 seconds. This shampoo operation was repeated twice. Next, 3 g of the model rinse shown in the formulation below was applied, allowed to acclimatize for 15 seconds, and then rinsed with tap water at 40 ° C. for 30 seconds. Then, after towel-drying, the hair was naturally dried for 6 hours under laboratory conditions and used as an evaluation hair bundle.
