Description

  The invention disclosed in this application relates to a hair cleansing composition. Specifically, the present invention relates to a hair cleansing composition that achieves good foaming and light washing comfort.

  Generally, a hair cleanser composition is used to wash away dirt on the hair and scalp. In general, the hair cleansing composition is used for preventing dandruff and itching of the scalp and keeping the hair and scalp clean.

  In order to realize a mild hair cleansing composition, conventionally, a technique of combining an amphoteric surfactant with an amino acid surfactant as an anionic surfactant has been adopted. However, when it was set as the hair cleaning composition which paid its attention to the combination of these surfactant, there existed problems, such as "poor foaming" and "because foam was sticky and it was hard to wash".

  As disclosed in Patent Document 1 below, an anionic surfactant having excellent foaming properties is used to make a creamy foam quality.

  In the following Patent Document 2, paragraph 0003, it is described that the detergent composition disclosed in Patent Document 1 below was not sufficiently irritating and the finish of the conditioner was not sufficient. In addition, it is said that the combined use of an ether carboxylate type surfactant, an ether sulfate type surfactant, and a specific cationic polymer is effective (Patent Document 2, paragraphs 0012 and 0035).

JP 2005-336387 JP 2008-285437 A

  However, conventionally provided hair cleansing compositions have not sufficiently solved problems such as “poor foaming” and “foam is sticky and difficult to wash”. Further, there is a need for a hair cleaning composition that achieves good foaming and light washing comfort.

  The cleaning compositions disclosed in Patent Document 1 and Patent Document 2 each contain a specific anionic surfactant and a specific cationic polymer as essential components.

  In general, many anionic surfactants are excellent in foaming power. In general, a cationic surfactant and a cationic polymer are components that contribute to improving the feel of hair. And there exists a technique of blending these in the same composition to form a complex and utilizing the complex. However, the present inventor has come to consider that it is difficult to realize good foaming and light washing comfort on the premise of relying on the use of the complex.

  Therefore, the present inventor has reviewed the composition and decided not to rely on a technique in which an anionic surfactant and a cationic surfactant or a cationic polymer are used in combination as essential components. And earnest research was repeated in order to complete the hair cleaning composition which implement | achieves a good foaming and light washing comfort.

  As a result, surprisingly, one or more selected from ether carboxylic acid type surfactants and salts thereof (component (A)), one or more selected from amphoteric surfactants (component (B)), and poly It is useful to use in combination one or more selected from glycerin monoalcohol ether, polyglycerin monofatty acid ester, polyoxyethylene sorbitan monofatty acid ester, alkyl glucoside, and fatty acid polyoxyethylene methyl glucoside (component (C)). I found.

  (I) good foaming property, (ii) fine texture and smooth foam quality, and good hair fingering (good operability), and ( iii) It is difficult to defoam after foaming, the cushioning property by the foam between the hair and scalp and the finger is maintained, and the finger-wiping property is continued (the foam retention during washing is good). The inventor of the present application considers that a well-balanced combination of the effects (i) to (iii) is important for realizing a light washing comfort. On the other hand, for example, if the foaming property is insufficient, it is easy to feel that the foam is sticky and heavy, and if the operability and the foam retention during the hair washing are insufficient, it becomes easy to feel heavy washing.

  From the above, it is an object to be solved to provide a hair cleansing composition that achieves good foaming and light washing comfort.

The foaming property, operability, and foam retention during the hair washing treatment were evaluated according to the following methods. The evaluation results of each example and each comparative example are shown in the table.

-Evaluation method-
<Foamability (good foaming)>
Of the 20 panelists, the number of panelists evaluated as having excellent foaming properties (good foaming) is “very excellent: 5” when the number is 17 or more, and “excellent: 4 ”, the case of 9 to 12 persons was evaluated as“ good: 3 ”, the case of 5 to 8 persons was evaluated as“ slightly defective: 2 ”, and the case of 4 persons or less was evaluated as“ defective: 1 ”.

<Operability (Foam quality with fine texture and smoothness, as per finger)>
The operability was evaluated from the viewpoint of foam quality that the texture is fine and smooth and the fingering of the hair.
Among the 20 panelists, the number of panelists evaluated as having good operability is “very good: 5” when the number is 17 or more, “excellent: 4” when 13 to 16 people, The case of 12 persons was evaluated as “good: 3”, the case of 5-8 persons was “slightly defective: 2”, and the case of 4 persons or less was evaluated as “defective: 1”.

[Table 1]

[Table 2]

[Table 3]

  The hair washing compositions according to all the examples had good balance in foaming properties, operability and evaluation of foam retention during hair washing, and realized a light washing comfort. In particular, in Examples 11 to 15, a lighter and more comfortable washing feeling was realized as compared with Examples 1 to 10.

  On the other hand, the composition for washing hair according to each comparative example has insufficient evaluation of any one of foaming property, operability and foam retention during hair washing, and cannot achieve a light washing comfort. It was. In Comparative Example 1 and Comparative Example 2 in which the foamability evaluation was insufficient, the operability and the evaluation of foam retention during washing were good, but the foaming itself at the start of washing was insufficient (the amount of foam was small). The foam was sticky and became a heavy wash.

  On the other hand, regarding Comparative Example 3 and Comparative Example 4 in which the operability and evaluation of foam retention during hair washing were insufficient, the following points can be pointed out although good foaming was exhibited at the start of hair washing. First, regarding the operability, the evaluation was insufficient even at the start of shampooing, not reaching each example. Furthermore, after foaming, it was easier to defoam compared to each example, the amount of foam was reduced during the hair washing, and the fingering property was lowered, and it became more comfortable to feel the weight.

  As described above, even if any one of foaming property, operability, and evaluation of foam retention during hair washing is good, the hair washing composition according to each comparative example realizes a light washing comfort. could not.

  As described above, it is considered that it is important that the evaluation of foaming property, operability, and foam retention during hair washing is well balanced in order to realize light washing comfort from the comparison between Examples and Comparative Examples.

  The hair washing compositions according to Examples 11 to 12 are considered to have improved foamability by adopting a suitable mass ratio of “(B) / (C)”.

  In Examples 13 to 15, it is considered that a plurality of suitable configurations are combined to realize a more comfortable light washing feeling.

  In Comparative Example 4 in which monooleyl glyceryl ether (the glycerin portion is not a glycerin polymer) was used instead of the component (C), a light washing comfort could not be realized. In Comparative Example 4, the mass ratio of the component (B) and monooleyl glyceryl ether was “(B) / monooleyl glyceryl ether” = 5, but the foaming evaluation was a comparative example in which no monooleyl glyceryl ether was blended. It was equivalent to 3.

-Test using wig for evaluation (undamaged hair)-
Except for using an evaluation wig that is undamaged hair that has not been decolorized, the hair cleaning composition according to each of the above Examples and Comparative Examples was tested in the same procedure as the above “Test Method”. Went. As a result, the same evaluation result as that obtained when the damaged hair was used was obtained.

  Therefore, it was thought that the hair cleaning composition which this application discloses exhibits an effect favorably in undamaged hair and damaged hair.

  The present application provides a hair cleansing composition that achieves good foaming and light washing comfort.
