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.

On the other hand, non-aqueous hair cosmetics have various uses other than hair oil. Patent Document 2 discloses a split coat agent containing an organic solvent, 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.

(Patent Document 1) JP-A-2011-195471 (Patent Document 2) JP-A-8-40839

The present invention contains the following components (A) to (C), the content of the component (A) is 0.1% by mass or more and 10% by mass or less, and the total content of the component (B) and the component (C) is 30%. Provided is a hair cosmetic composition having a mass ratio (B) / (C) of 0.8% to 99% by mass and above.
(A): Polymer for hair cosmetics having solubility or dispersibility in water or ethanol (B): Monohydric alcohol having 1 to 4 carbon atoms (C): Silicone oil having a number average molecular weight of 100 or more and 1500 or less

Detailed Description of the Invention

When the hair oil of Patent Document 1 is applied to wet hair after shampooing, it can give a feeling of unity and conditioning after drying, but when applied to dry hair, there is still uneven application, There was a problem that the unity and feeling after drying were 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.

In addition, it is said that the split hair coating agent of Patent Document 2 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 has good wet spread when applied to dry hair, and dries immediately after application, does not give a squeaky feeling or a feeling of wet hair, and after drying the hair naturally without making hair bundles. The present invention relates to a hair cosmetic that can be put together.

The inventors of the present invention have a problem in the above-described non-aqueous hair cosmetics mainly that the wet spreadability on dry hair is insufficient and that volatile oil takes time to volatilize after application. I thought and examined it. As a result, when specific silicone oil and lower alcohol are in a specific ratio, the surface tension of the solvent increases remarkably, and the hair cosmetic applied on the hair moves spontaneously on the hair surface, while the contained polymer is on the hair surface. Found to coat. 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.

The hair cosmetic composition of the present invention spontaneously moves on the hair surface with dry hair and dries quickly. 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 nothing is attached Gives a natural unity while being a touch. Furthermore, there is no squeak or stickiness when applied, and the hair does not feel wet.
