Description

  The present invention relates to a hair cosmetic, particularly a hair cosmetic suitable for use as a hair conditioner, hair rinse or hair treatment. ADVANTAGE OF THE INVENTION According to this invention, the hair cosmetics excellent in the dry feeling after hair drying, suppleness, luster (luster), the persistence of an odor, and the moisture of the background can be obtained.

In general, after the hair is washed with shampoo or the like, the gloss and finger passage are deteriorated, so that hair cosmetics such as rinses, hair conditioners and treatments are used.
Such hair cosmetics usually contain a quaternary ammonium salt type cationic surfactant. The quaternary ammonium salt type cationic surfactant has an effect of imparting flexibility and antistatic effect to the hair.

  For example, Patent Document 1 contains a quaternary ammonium salt type cationic surfactant, 3-methyl-1,3-butanediol, and petrolatum, and is excellent in the moist feeling and softness of the finished hair. A hair cosmetic for rinsing is disclosed. Patent Document 2 discloses a hair cosmetic composition that is blended with an ether type cationic surfactant (quaternary ammonium salt) and petrolatum and is excellent in hair flexibility, smoothness, smoothness, and moist feeling. ing. Further, Patent Document 3 discloses a hair cosmetic that can be blended with a polysaccharide, a tertiary amine, and a higher alcohol to give a sense of unity and a slipperiness. In addition, a hair cosmetic containing silicone or a silicone derivative has been proposed in order to obtain a smooth feeling after the hair is dried (Patent Document 4).

However, it is difficult to say that the hair cosmetics described in Patent Documents 1 and 2 have a sufficiently moist feeling and smoothness that are currently required. Further, the hair cosmetic described in Patent Document 3 has stickiness and firmness, and sufficient hair flexibility cannot be obtained.
Therefore, it has excellent usability, such as smoothness during use, easy fingering, and easy washing, as well as smoothness, moistness, softness, smoothness, gloss, and combing of the hair after use. Hair cosmetics were desired. Furthermore, in recent years, there are many people who hurt hair due to the influence of ultraviolet rays, overheating of a dryer, etc., and hair cosmetics having an improvement effect on these hairs have also been demanded.
The object of the present invention is to feel at the time of use (smoothness, easy to pass through, and easy to wash away), finish feeling after use (smoothness, suppleness, moistness, softness) in the present hair cosmetics. , Smoothness, gloss, odor persistence, combing, etc.) and a moisturizing feeling of the background.
Moreover, when using a hair dye, it is known that the hair dye | stain will worsen if silicone has adhered to hair. Therefore, recently, non-silicone hair cosmetics that do not contain silicone and silicone derivatives have been developed. However, hair cosmetics that do not contain silicone do not provide a smooth feeling after the hair has been dried.
Accordingly, another object of the present invention is to provide a hair cosmetic that is excellent in the dry feeling after drying without containing silicone or silicone derivatives.

As a result of intensive studies to solve the above problems, the present inventor surprisingly includes a cationic surfactant, a specific nonionic surfactant, an oil component, and a cationic polymer. By setting the weight ratio (a) / (b) of the surfactant (a) to the nonionic surfactant (b) to 2 to 45, smoothness during use, good fingering, and Easily rinse away, and after use, the hair feels smooth, supple, moist, soft, smooth, glossy, odor persistence, moisturizing the skin, and a hair cosmetic that is excellent in combing. I found out that I can. In particular, the present invention has the above-mentioned characteristics, so that the hair feels smooth, supple, and smelly after use, gives the hair an excellent luster, and further moisturizes the background. It is something that can be done.
The present invention is based on these findings.

Moreover, according to the hair cosmetic composition of the present invention, it is possible to give the hair an excellent gloss, excellent odor persistence, and an excellent moisture to the background. Moreover, sufficient use satisfaction can be given not only to healthy hair but also to damaged hair.

  In addition, as described above, when a hair dye is used, hair dyeing becomes worse if silicone is attached to the hair. Therefore, when dyeing hair, an increasing number of people use non-silicone hair cosmetics that do not contain silicone or silicone derivatives. According to the hair cosmetic composition of the present invention, it is possible to provide a hair cosmetic composition that is excellent in the dry feeling after drying without containing silicone and silicone derivatives.

As a method for calculating the HLB of the nonionic surfactant, there are the Griffin method, the Divis method, the Atlas method, the Kawakami method, and the like. The HLB in this specification is calculated by the Griffin method. The HLB by the Griffin method can be calculated by the following equation.
