Description

Hair cosmetic

The present invention relates to a hair cosmetic such as a hair rinse, a hair conditioner, a hair treatment, and a hair mask which are used after shampoo shampooing.

In order to improve the carding performance in shampooing, there is a technique called "coagulation" for shampoo application. Coacervation refers to the following technique: an anionic surfactant contained in a shampoo and a cationized polymer form an insoluble complex during rinsing with water after shampooing and adsorbed on the surface of the hair, thereby being used for shampooing and rinsing Reduces the friction on the surface of the hair, giving a smooth comb.

On the other hand, the shampoo or conditioner, hair conditioner, hair mask (hereinafter collectively referred to as moisturizer) which is used after shampooing with shampoo contains an oily component such as polyfluorene oxide and alkane. A cationic surfactant having a base chain length of 16 or more and a higher alcohol can impart softness or smooth combability to damaged hair (for example, see Patent Document 1). The reason for this is that a cationic surfactant, a lubricating component such as a higher alcohol or a polyfluorene oxide, is efficiently adsorbed on the surface of the hair.

(Patent Document 1) Japanese Patent Laid-Open Publication No. 2002-29937

The present invention provides a hair cosmetic comprising the following components (A) to (C), and the mass ratio (A)/(C) of the component (A) to the component (C) is 3 or more and 200 or less, and the composition The mass ratio (B)/(C) of the component (B) to the component (C) exceeds 1 and is 100 or less.

(A): Single long-chain alkyl type cation interfacial activity with one alkyl group having 18 to 24 carbon atoms Agent

0.05% by mass or more and 15% by mass or less

(B): a long-chain alkyl type cationic surfactant having two alkyl chains having 10 to 18 carbon atoms

0.01% by mass or more and 5% by mass or less

(C): Single long-chain alkyl type cationic surfactant having one alkyl group having 12 to 17 carbon atoms

The above-mentioned lubricating component contained in the conditioner can be sufficiently adsorbed to the hair when the shampoo used for shampoo is not used in the aggregation technique (that is, in the case where the cationized polymer is not contained), and the original conditioning property is exerted. However, when the shampoo used for shampoo utilizes a coagulation technique (hereinafter referred to as "coagulation shampoo"), the adsorption of the lubricating component to the hair is suppressed, and the adjustment performance is remarkably lowered. This phenomenon is more pronounced when the friction reducing performance of the shampoo is higher. That is, there is a trade-off relationship between the friction reducing performance of the coherent shampoo and the conditioning performance of the moisturizing milk, which is difficult to achieve at the same time using the prior art.

Accordingly, the present invention relates to a hair cosmetic such as a hair lotion which exhibits high conditioning performance even for hair washed with a coherent shampoo.

It is considered that the performance of the hair conditioner due to the treatment of hair by the shampoo is caused by the fact that the anionic surfactant/cationized polymer complex remaining on the surface of the hair after rinsing the above shampoo is inhibited as a moisturizing ingredient Adsorption of lubricating components. Therefore, the inventors of the present invention have developed a hair lotion which is not susceptible to the above-described complex which remains on the surface of the hair after shampooing.

As a result, it has been found that by combining three kinds of cationic surfactants having a specific alkyl chain, the performance degradation caused by coagulation shampoo can be suppressed, and the original moisturizing milk can be maintained. Slip performance.

The hair cosmetic of the present invention exhibits a sufficient adjustment effect not only when it is used in combination with a shampoo containing no cationized polymer, but also exhibits sufficient adjustment performance when used in combination with a shampoo. Thereby, it is possible to effectively exert the thick feeling and easy affinity when applied to the hair, the softness during rinsing, the good combability, the softness when dried with a towel, the good combability, and the ease of drying with a hair dryer. Dry, good combing, good combability after drying, homogenization, hydrophobization of the surface of the hair which is hydrophilized by damage, good combability and homogenization of the next shampoo.
