Description

Water-based hair cleaner

The present invention relates to an aqueous hair cleanser.

In hair cleansers, in order to improve cleansing power, foaming, touch, etc., two or more surfactants are usually combined. Among them, various proposals have been made about hair cleansers that combine two or more nonionic surfactants. .

For example, Patent Document 1 discloses a personal cleansing and removing agent that is excellent for removing hair or skin attachments, which contains a polyether modified with HLB (Hydrophile Lipophile Balance, hydrophilic/oil ratio) of 8.0 to 11.0 and 12.0 to 15.0. Polysiloxane, and non-ionic surfactant. Patent Document 2 discloses a neutral liquid cleanser composition that has low skin or hair irritation, good touch and foam rinseability, which is a non-ionic interface active with alkyl glucoside and HLB less than 5 Used in combination with non-ionic surfactants with HLB of 5 or more. In addition, Patent Document 3 discloses a detergent composition having a high cleaning power against oil stains, which is formed by combining two specific anionic surfactants and two or more nonionic surfactants in a certain amount ratio.

(Patent Document 2) Japanese Patent Laid-Open No. 3-50299

(Patent Document 3) Japanese Patent Laid-Open No. 10-226796

The present invention provides an aqueous hair cleanser, which contains the following components (A) and (B)

(A) Anionic surfactant

(B) Polyoxyethylene alkyl ether, the content of component (A) is 5 mass% or more and 30 mass% or less, the content of component (B) is 0.5 mass% or more and 10 mass% or less, component (B) and components (A) The mass ratio (B)/(A) is 0.05 or more and 1 or less, and the carbon number of the component (B) is an alkyl group of 10 to 14, and the number of ethylene oxide addition moles is 0 to 30 A mixture of two or more compounds, and the component (B) contains the following component (b-1) and component (b-2) at 5% by mass or more, and a total of 60% by mass or more and 100% by mass or less,

Here, the percentage of people who fail to clean the scalp reliably during shampooing is quite high. In the case of normal shampooing, apply shampoo on the spontaneous surface and move your fingers to foam the shampoo to spread the shampoo ingredients to the entire scalp or hair. For example, for women with more hair In this case, because there are more hairs on the scalp, the foam of the shampoo does not reach the scalp. In addition, in the case of children, even if the hair is shampooed, the scalp is not carefully washed, and the foam of the shampoo does not reach the skin in most cases. Furthermore, in the case of fingers with nails, which are popular in recent years, the fingers cannot be raised up and moved by touching the surface of the hair, so it is difficult to clean the scalp reliably. If the scalp is not cleaned sufficiently, sebum dirt or bacteria remains unremoved, and it appears as skin symptoms such as dandruff, itching, and odor in most cases.

The inventors of the present invention believe that under the current situation that the scalp is not sufficiently cleansed, it is one of the reasons why it is difficult for the cleansing agent components to reach the scalp over the barrier of hair. The shampoo performed directly after the cleansing of the skin failed to sufficiently wash the scalp. Although the hair cleansers described in Patent Documents 1 to 3 have improved cleansing power themselves, they are not those whose cleansing components can quickly reach the scalp, and therefore cannot solve the above-mentioned problems.

Therefore, the present invention relates to a hair cleansing agent. The cleansing agent components are easily fused into the hair and can quickly reach the scalp. The cleansing property is better, and the smoothness and no residual feeling during washing are also better.

The inventors of the present invention found that in water-based hair cleansers, the ratio of polyoxyethylene alkyl ethers with relatively short alkyl chains and whose ethylene oxide addition mol number is in two different ranges Those which are equal to or more than a certain amount are used in combination with an anionic surfactant at a certain ratio to satisfy the above requirements.
