The present invention relates to a hair cleansing composition, and more particularly, contains a cocoyl methyl taurine salt, an N-acyl amino acid salt, and betaine lauryldimethylaminoacetic acid, has a viscosity excellent in usability, and has foaming during use. It relates to a hair cleansing composition excellent in goodness, fineness of foam, good foam retention and smoothness of foam.

Conventionally, in compositions for washing hair, various functions such as detergency, foaming, sensuality such as finger passage during rinsing, and usability such as viscosity suitable for use are taken into consideration according to the purpose and application. Surfactants have been selected and used in combination. Among various surfactants, a sulfuric acid-based anionic surfactant having high foaming property, detergency, and appropriate viscosity is blended as a main cleaning component in many detergent compositions.

However, in recent years, due to the growing interest in the scalp and skin, there is increasing interest in amino acid-based surfactants and taurine-based surfactants, which are less irritating as anion activators.
In response to these demands, N-acylamino acid-based surfactants have been used in body and hair cleaning agents as excellent, low-irritant surfactants that have a cleaning effect without damaging the skin or hair (patented). (Refer to Document 1), the development of shampoo compositions having sufficient viscosity suitable for use using amino acid-based anionic surfactants such as N-acylamino acid salts has been studied (see Patent Documents 2 to 4). ..

International Publication 2012/029514 Pamphlet Japanese Unexamined Patent Publication No. 2014-88348 Japanese Unexamined Patent Publication No. 2001-278727 Japanese Patent Application Laid-Open No. 2003-34623

In Patent Documents 2 and 3, a technique for improving the viscosity of a liquid cleaning agent composition by combining an amino acid-based surfactant such as a glutamic acid derivative with a specific acrylic acid-based copolymer or a polymer such as xylrolcan. Has been reported. In these techniques, it is necessary to add a considerable amount of a specific polymer, which causes a problem that the agent becomes turbid or cloudy, and foaming is delayed.
Further, Patent Document 4 reports a technique in which an amphoteric surfactant is combined with an N-acylmethyltaurine salt and an N-acylamino acid salt. In this technique, there is no irritating feeling to the scalp, and although the foaming power and the finished feeling are improved, there is a problem that the viscosity is low and it is not suitable for usability.
From the above, no report has been made on a hair detergent composition having both good foam quality and suitable viscosity by combining an N-acylmethyltaurine salt and an N-acylamino acid-based surfactant.

In view of the above circumstances, the present inventors have found that the viscosity of a mixture of cocoylmethyltaurine salt and N-acylamino acid salt is suitably increased by further containing betaine lauryldimethylaminoacetic acid. As a result of further verification, a hair detergent composition containing 0.3 to 10% by mass of cocoyl methyl taurine salt, 0.3 to 6% by mass of N-acylamino acid salt, and betaine lauryldimethylaminoacetic acid was found. It has been found that it has a viscosity suitable for use, and also has good foaming, fineness of foam, foaminess, and smoothness of foam when washing hair. Again, when the above-mentioned hair detergent composition further contains α-olefin sulfonate, not only the viscosity becomes more suitable, but also the transparency is increased and the stability over time is excellent, and further. We have found that the fineness of foam, the stickiness of foam, and the smoothness of foam become better when amino acids are contained, and have completed the present invention.

That is, in the present invention, the following components (a) to (c),
(A) Cocoyl methyl taurine salt 0.3 to 6% by mass
(B) N-acylamino acid salt 0.3 to 10% by mass

[Four-step criteria (foam height value by Rosmiles method)]
⊚: 300 mm or more ○: 200 mm or more and less than 300 mm Δ: 50 mm or more and less than 200 mm ×: less than 50 mm

<(C) Fineness of foam, (D) Good foam retention, (E) Smoothness of foam evaluation method>
When 20 cosmetics specialist panels wash their hair with 6 g of each sample without any hair styling products, the fineness of the foam, the goodness of the foam, and the smoothness of the foam , The evaluation was made in 5 stages according to the evaluation criteria (I) shown below, and the average score of the scores of all the panels was further judged according to the following criteria (II).
[Evaluation Criteria (I)]
[Evaluation result]: [Score]
Very good: 5 points good: 4 points normal: 3 points slightly defective: 2 points defective: 1 point
[Criteria (II)]
[Average score]: [Judgment]
4.5 or above: ◎
3.5 or more and less than 4.5: ○
1.5 or more and less than 3.5: △
Less than 1.5: ×

As is clear from the results in Table 1, the hair cleansing compositions of Examples 1 to 6 have higher viscosity, better foaming, finer foam, and foam than the hair cleansing compositions of Comparative Examples 1 to 5. It was excellent in terms of stickiness and smoothness of foam.
On the other hand, in Comparative Example 1 in which the amount of the component (a) was less than 0.3%, a satisfactory foaming property and foaming property could not be obtained as compared with Example 2. In Comparative Example 2 in which the amount of the component (a) exceeded 6%, no satisfactory foam was obtained in terms of fineness of foam and smoothness of foam as compared with Example 5.
Further, in Comparative Example 3 in which the amount of the component (b) was less than 0.3%, sufficient viscosity could not be obtained as compared with Example 5, and the smoothness of the foam was satisfactory. However, in Comparative Example 4 in which the amount of the component (b) exceeded 10%, a satisfactory foaming property and foaming property were not obtained as compared with Example 2.
In Comparative Example 5 in which cocamidopropyl betaine was used instead of the component (c), a sufficient viscosity could not be obtained as compared with Example 2, and a satisfactory one in usability could not be obtained.
