Description

Hair cosmetics

The present invention relates to hair cosmetics.

In recent years, the hairstyles that consumers want have changed. For this reason, the performance required of hairdressing agents is also that of fixing hair with conventional adhesive polymers and film-forming polymers, maintaining a natural sense of unity, and feeling the hair after finishing is also flexible and natural It has changed to. In particular, recent women are demanding a hair styling agent that feels like it has nothing to touch and has a natural appearance without a sense of bunch, and is well-organized as a finger.

In response to such demands, there are non-aqueous hair cosmetics, especially products that are generally called hair oils, but due to the oil contained in the products, the oils are used at the time of application and after application to the hair. There were problems such as the feeling of slipping over for a while, the feeling of unnatural hair bundles remaining, the appearance and feel of the hair after application, and the stickiness remaining.

In order to solve the above problems in hair oil, for example, Patent Document 1 discloses a hair oil using a polyether-modified silicone having a specific structure, a volatile oil, and ethanol in combination. This document discloses that this hair oil is free from oiliness immediately after application, has good hair fit, and improves the crispness over time.

Patent Document 2 discloses a specific isoparaffinic hydrocarbon and a quick-drying hair oil containing the specific hydrocarbon. The literature discloses that this quick-drying hair oil can be applied to wet hair to shorten the time to dry the hair and to give a conditioning effect to the dried hair.

On the other hand, non-aqueous hair cosmetics have various uses other than hair oil. Patent Document 3 discloses a split hair coating agent containing an organic solvent, a volatile oil, and a specific dimethylpolysiloxane derivative. The document discloses that the split coat agent can coat split ends without stickiness and can be easily washed away.

Detailed Description of the Invention

The hair oils of Patent Documents 1 and 2 can give a feeling of unity and conditioning after drying when applied to wet hair after washing, but when applied to dry hair, the damage level of the hair Due to the difference in wetness and spread, there is a problem in that the wetness and spread are not uniform, and the unity and feeling after drying are insufficient. In addition, when a sufficient amount is applied so that it can be uniformly applied to the entire hair, there is a problem that the weight and the feeling of hair bundle remain after drying. Furthermore, although the hair oil of Patent Document 2 can increase the water evaporation rate of wet hair after shampooing, it has a strong unnatural touch due to volatile oil until it is dried after being applied to dry hair, There was room for improvement.

In addition, it is said that the split hair coating agent of Patent Document 3 preferably contains 10 to 50% by weight, particularly 20 to 40% by weight, of a dimethylpolysiloxane derivative in the entire composition in order to coat split ends. . For this reason, the dimethylpolysiloxane derivative remaining on the hair in a large amount even after drying has left a feeling of weight and hair bundle, and it has been difficult to make it feel smooth.

Therefore, the present invention can spread evenly regardless of the damage level of the hair when applied to dry hair, and dries immediately after application, does not give a squeaky feeling or a wet feel, and after drying The present invention relates to a hair cosmetic that can bundle hair naturally without making a hair bundle.

The inventors of the present invention have problems with the above-mentioned non-aqueous hair cosmetics, mainly because of the damage level on the hair, the wet spreadability differs on dry hair, and the time for volatile oil to volatilize after application. We considered that this was the case and examined it. As a result, when a certain ratio of specific volatile oil and lower alcohol is used, the surface tension of the solvent is remarkably lowered, and the hair cosmetic applied on the hair spreads quickly and evenly regardless of the damage level. I found out. As a result, the polymer component contained can be quickly and uniformly applied to the hair surface, and further dried extremely quickly, so that the presence of hair cosmetics disappears on the hair immediately after application, and after drying The invention was completed by finding that the hair of the hair was gathered.

In the hair cosmetic composition of the present invention, the wetness and spreadability of the hair surface with dry hair is remarkably improved, and the hair cosmetic composition dries quickly while spontaneously spreading. For this reason, the polymer in the hair cosmetic quickly spreads thinly and evenly on the hair surface, and after application, the presence of the hair cosmetic disappears quickly, and there is no unnatural hair bundle feeling and no touch However, it gives a natural unity. Furthermore, there is no squeak or stickiness when applied, and the hair does not feel wet.

Hereinafter, the present invention will be described more specifically with reference to examples. The present invention is not limited to these examples.

[Experimental Examples 1 to 13]
In order to confirm the spontaneous wetting and spreading properties on the surface of damaged hair and the surface of healthy hair, the compositions shown in Table 1 were prepared, and each was micropipetted (Research Plus V 3120, manufactured by Eppendorf). 50 μL each was dropped from 1 cm above the film surface onto a hydrophilic surface film (clean film, manufactured by Alfolia) and a hydrophobic surface film (reproduction clear holder, manufactured by Otsuka Corporation, model number TCHEA4-100). The major axis and minor axis of the droplet spreading on the film surface 30 seconds after the dropping were measured, and the area was calculated by (major axis x minor axis x circumference ratio).

As can be seen from Experimental Examples 1 to 5, the component (B) and the component (C) are contained, and the mass ratio (B) / (C) of the component (B) to the component (C) is within the range of claim 1. In some cases, droplets are larger in both the hydrophilic film and the hydrophobic film than in the case of containing only the component (B) (Experimental Example 6) and in the case of containing only the component (C) (Experimental Example 8). It spreads and spontaneous wetting and spreading was excellent. On the other hand, this effect was not observed when the liquid oil did not correspond to the component (C) as in Experimental Examples 10 to 13.

[Examples 1 to 6 and Comparative Examples 1 to 6]
With reference to the experimental examples, hair cosmetics described in Table 2 were prepared by a conventional method, and spontaneous wetting and spreading properties to hydrophilic films and hydrophobic films were evaluated in the same manner as in the experimental examples.
In addition, the hair cosmetics listed in Table 2 are filled into a pump spray container (manufactured by Yoshino Seisakusho Co., Ltd., using a sprayer having an average particle diameter of 60 μm when the hair cosmetics of Examples and Comparative Examples are sprayed), Performance evaluation was performed according to the following methods and standards.

(Evaluation hair bundle)
A hair bundle with a length of 30 cm and a weight of 8 g was made of Japanese weak hair with no chemical treatment history. The hair bundle was coated with 3 g of Kao's success medicated shampoo h, foamed and washed for 30 seconds, and rinsed with tap water at 40 ° C. for 30 seconds. This shampoo operation was repeated twice. Next, 3 g of model rinse shown in the following prescription was applied, allowed to blend for 15 seconds, and then rinsed with tap water at 40 ° C. for 30 seconds. Next, after drying with towels, those naturally dried under laboratory conditions for 6 hours were used as evaluation hair bundles.
