Description

The present invention relates to a hair washing composition and a hair washing method.

The hair washing composition used for washing hair usually contains a surfactant such as an anionic surfactant as a washing component. In addition to the surfactant, various components are used in order to impart various functions to the hair washing composition.

For example, Patent Document 1 below contains a polyoxyalkylene alkyl ether sulfate, a betaine-type amphoteric surfactant, a cationized polymer having a sugar skeleton, an inorganic salt, and a polyglycerin fatty acid ester having an HLB of 12 or more. According to the viscous hair cleansing composition, it is easy to discharge from the container even at low temperature, has excellent detergency (sebum removing property), and is excellent for finger passage of hair during rinsing. The technology that can be provided by is proposed.

Japanese Unexamined Patent Publication No. 2008-081415

As shown in the above background technique, a surfactant is blended as a cleansing component in the hair cleansing composition, but foaming may occur depending on the type and amount of the surfactant blended in the hair cleansing composition. In the worst case, the foam becomes coarse and inelastic, so that the hair may be easily caught or entangled with each other during washing the hair.

In addition, when the hair was washed using the hair washing composition, the components of the hair washing composition remained on the hair even after rinsing, so that the treatment was treated and dried after the hair washing. The hair could be dry and hard to the touch.

Therefore, in the hair washing composition, it is required to have excellent foaming and foam quality (foam with fine and elastic foam) and to improve the feel of hair after the treatment treatment (feeling moist and soft). Although Patent Document 1 has a proposal to enhance detergency and the like, it is excellent in foaming and foaming quality, and improvement of the feel of hair after treatment treatment has not been studied.

In view of the above circumstances, it is an object of the present invention to provide a hair washing composition having excellent foaming and foaming quality and excellent texture of hair after treatment treatment.
Another object of the present invention is to provide a hair washing method using a hair washing composition which is excellent in foaming and foam quality and has excellent texture of hair after treatment treatment.

As a result of diligent studies by the present inventors, N-acylamino acids or salts thereof, α-olefin sulfonic acid or salts thereof, polyoxyethylene alkyl ether carboxylic acid or salts thereof, and amphoteric surfactants have been added to the hair cleaning composition. Foaming and foaming can be achieved by setting the mass ratio of the amount of the anionic surfactant to the amount of the amphoteric surfactant in the hair cleaning composition to be 0.9 or more and 2.2 or less. The present invention has been completed based on the finding that it is possible to provide a composition for cleaning hair having excellent foam quality (fine and elastic foam) and excellent texture of hair after treatment treatment.

It is preferable because the foam quality is better and the texture of the hair after the treatment treatment is better.

When the above-mentioned composition for washing hair according to the present invention contains the amidoalkylbetaine type amphoteric tenside agent as the (D) amphoteric tenside agent, the feel of the hair after the treatment treatment is more excellent. It is preferable because it becomes a waste.

In the above-mentioned composition for washing hair according to the present invention, if the total amount of the anionic surfactant and (D) the amphoteric tenside is 22% by mass or less, skin irritation may occur. It is preferable from the viewpoint of reducing the amount of water.

The above-mentioned hair washing composition according to the present invention preferably contains a nonionic surfactant from the viewpoint of increasing the viscosity of the hair washing composition.

When the above-mentioned composition for washing hair according to the present invention contains a monoester of a polyhydric alcohol and a fatty acid as the nonionic surfactant, it is preferable because the foam quality is more excellent.

The above-mentioned composition for washing hair according to the present invention does not contain, for example, alkyl ether sulfuric acid or a salt thereof, or the amount of alkyl ether sulfuric acid or a salt thereof is 1% by mass or less.

The hair washing method according to the present invention is a hair washing method using any of the above-mentioned hair washing compositions according to the present invention.

According to the hair washing composition according to the present invention, it is possible to provide a hair washing composition which is excellent in foaming and foam quality and is excellent in the feel of hair after the treatment treatment.
