Description

Hair cosmetic

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

In order to improve the combing performance in shampooing, a technique called "coacervation" is applied to shampoo. Coacervation refers to the following technology: the anionic surfactant and the cationized polymer contained in the shampoo form an insoluble complex during the process of rinsing with water after shampooing and are adsorbed on the surface of the hair. Reduces friction on hair surface and gives smooth combability.

On the other hand, the conditioner or conditioner, conditioner, and hair mask (collectively referred to as conditioner) used immediately after shampooing with shampoo contain oily ingredients such as silicone and alkane in general A cationic surfactant and a higher alcohol having a base chain length of 16 or more can impart properties such as softness and smooth combability to damaged hair (for example, refer to Patent Document 1). This is because lubricating ingredients such as cationic surfactants, higher alcohols, and polysiloxane are efficiently adsorbed on the hair surface.

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

The present invention provides a hair cosmetic material containing 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. The mass ratio (B) / (C) of (B) and component (C) exceeds 1 and is 100 or less.

(A): Single long chain alkyl type cationic interface activity with an alkyl group having 18 to 24 carbon atoms Agent

0.05 mass% or more and 15 mass% or less

(B): Two long-chain alkyl cationic surfactants with two alkyl chains of 10 to 18 carbons

0.01 mass% or more and 5 mass% or less

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

The above-mentioned lubricating ingredients contained in the conditioner can be sufficiently adsorbed on the hair when the shampoo used for shampooing does not use the coagulation technology (that is, the case without the cationized polymer), and the original conditioning performance can be exerted. However, when the shampoo used for shampooing uses a coacervation technology (hereinafter referred to as "coacervation shampoo"), the adsorption of the above-mentioned lubricating component to the hair is suppressed, and the conditioning performance is significantly reduced. This phenomenon becomes more pronounced as the friction reducing performance of the condensing shampoo is higher. That is, there is a trade-off relationship between the friction reducing performance of the condensed shampoo and the conditioning performance of the conditioner, and it is difficult to achieve these properties simultaneously using the prior art.

Therefore, the present invention relates to a hair cosmetic material such as a hair conditioner that exhibits high conditioning performance even on hair washed with a condensed shampoo.

It is thought that the performance of hair conditioner is reduced due to the treatment of hair by agglomerating shampoo. The reason is that the anionic surfactant / cationic polymer complex remaining on the hair surface after rinsing the above shampoo hinders the use as a hair conditioner ingredient. Adsorption of lubricating ingredients. Therefore, the present inventors have developed a conditioner which is not easily affected by the above complexes remaining on the hair surface after shampooing.

As a result, it was found that by combining three kinds of cationic surfactants having a specific alkyl chain, it is possible to suppress the decrease in performance caused by the agglomeration of shampoo and maintain the original moisturizing conditioner. Slip performance.

The hair cosmetic material of the present invention not only exerts a sufficient conditioning effect when used in combination with a shampoo containing no cationized polymer, but also fully exerts a conditioning performance when used in combination with a condensed shampoo. This can effectively exert the thick feeling and easy affinity when applied to hair, softness when rinsed, good combability, softness when dried with a towel, good combability, and ease when dried with a hair dryer Dryness, good combability, good combability after drying, uniform texture, hydrophobization of the surface of the hair that is hydrophilized due to damage, good combability, uniform texture during the next shampoo, and other effects.
