Description

The present invention relates to a hair treatment composition and a hair treatment method. More specifically, the present invention secures the original effect of the starch phosphate blending in the hair treatment agent blended with starch phosphate (starch phosphate), and its problems (especially when applying to damaged hair). ) And a hair treatment method performed using the hair treatment composition.

Conventionally, various hair treatment agents containing starch and derivatives thereof have been proposed. In particular, when starch phosphate (starch phosphate) is blended, it is known that hair entanglement can be eliminated and a smoothing effect can be obtained.
For example, the following Patent Document 1 discloses a starch-containing cosmetic composition and a cleaning composition containing a hydroxyalkyl starch or acyl starch having a specific carbon number, and describes that this composition can be used as a hair styling property improver. In the examples, the combing quality of the hair at the time of use is evaluated.

JP 2000-514435 A Also, for example, in the following Patent Document 2 and Patent Document 3, a combination of starch phosphoric acid and a cationic polymer or a specific oil agent is disclosed. It is said that a soft feel to the hair is imparted, or a “residue-free feel” in the hair is obtained. Furthermore, for example, Patent Document 4 below discloses a hair treatment containing starch phosphate.

However, according to the research of the present inventor, in the above-mentioned various compositions, there is no richness as a cream agent, an appropriate elasticity of the hair after treatment cannot be obtained, and furthermore, the lightness of the hair root ( This is accompanied by problems such as the hair does not lose its volume and feels fluffy). In particular, those defects are remarkable for damaged hair damaged by permanent wave treatment, decolorization, hair dyeing treatment, and the like.
In addition, in the above-mentioned Patent Document 1, it is stated on the 23rd page or the like that “a good result was obtained with a hair rinse in a certain embodiment in a use test with damaged hair”. The meaning of "result" and the evaluation method are unknown. Even in the above-mentioned other patent documents, there are some descriptions of application to damaged hair, but specific evaluation and effect confirmation for damaged hair are not performed. As the inventor of the present invention specifically evaluated the composition corresponding to the above prior art, no positive result was obtained as described as a comparative example in the “Example” section below.
Therefore, the present invention relates to the above-mentioned problems in hair treatment agents containing starch phosphate (especially problems when applied to damaged hair), specifically, lack of richness when applying the hair treatment agent, To solve the problem of providing a hair treatment composition that satisfactorily solves problems such as lack of appropriate elasticity or softness of hair, lack of lightness of hair root, and a hair treatment method using the same. It should be a challenge.

That is, the component (A) of the hair treatment composition has the effect of eliminating hair tangles and smoothing as described above, but even if this is blended alone, the richness and finish when applied as a cream agent There are problems in terms of the softness and elasticity of the hair after the treatment (after treatment), the lightness of the hair root, and the like. On the other hand, even if the (B) component is combined and blended, the richness, elasticity and the like are improved to some extent, but it is completely unsatisfactory for practical use.
The inventor of the present application is that, by further combining and blending the component (C), a body that is practically satisfactory in a hair treatment agent, softness of the hair after finishing, elasticity and lightness of the root can be obtained. I found it. In addition, in the combination formulation of the component (A) and the component (C), the effect of improving the richness and elasticity remains at the same level as in the combination formulation of the component (A) and the component (B) or less is there.

(Evaluation results)
As can be seen from the evaluation results shown in Table 1, Table 3 and Table 4, Examples 1 to 36 were very high evaluation results in any evaluation item.
Further, as can be seen from the evaluation results shown in Table 2, in Comparative Examples 2, 3, 5, 6, 9, and 10, which are practical examples of the present invention, the amount of any of the essential components is too small or excessive. Therefore, each of the examples shown in Table 1, Table 3, and Table 4 is highly evaluated as a whole in comparison with Comparative Examples 1, 4, 7, 8, and 11, which lack any of the essential components. Compared with, the evaluation is relatively low.
Furthermore, the following points can be pointed out from the overall evaluation results shown in Table 2.
1) If the blending amount of the component (A) is too small, the required elasticity of the cream and the finished hair cannot be ensured. The softness of the hair is lost without becoming sex. When the component (A) is not blended or when the “A ratio” component is blended instead of the component (A), the elasticity of the finished hair cannot be obtained.

2) If the blending amount of the component (B) is too small, neither the richness of the cream nor the elasticity of the finished hair can be obtained, and if it is excessive, the cream becomes watery and does not feel rich. Also not elastic. When the “B ratio” component is blended instead of the component (B), the result is the same as when the blending amount of the component (B) is too small.
3) If the blending amount of component (C) is too small, a creamy body can be obtained to some extent, but the elasticity of the hair after finishing cannot be obtained at all, and if it is excessive, the elasticity will not be appropriate. The softness of the hair is lost and the richness of the cream is not obtained. When the component (C) is not blended, neither the richness of the cream nor the elasticity of the finished hair can be obtained.

The required number of untreated hair bundles of human black hair having a length of 20 cm, which has not yet been subjected to decolorization treatment or permanent wave treatment, which is a cause of hair damage, was prepared. In addition, for the evaluation of “lightness of hair root”, untreated model wig hair not yet subjected to the above-mentioned treatment as a damage factor was prepared.
Example 1 (Table 1), Example 16 (Table 3), and Example 29 (Table 4) were filled in 50 g ointment containers after shampooing the hair of these hair bundles or model wigs. And the hair treatment which concerns on the comparative example 1, the comparative example 7, the comparative example 8 (all are Table 2) is apply | coated similarly to the case of 1st Example, and about the evaluation items similar to the case of 1st Example, Evaluation was performed using the same evaluation method and evaluation criteria. These evaluation results are shown in Table 5 at the end.
As a result, as shown in Table 5, with respect to Example 1, Example 16, and Example 29, evaluation results exactly the same as those of the first example were obtained.
On the other hand, in Comparative Example 1, Comparative Example 7, and Comparative Example 8, “Cream of Cream” was of course the same evaluation as in the first example, but “Softness of Hair”, “Elasticity” The evaluation results for each of the evaluation items of “lightness of hair root” were “△”. That is, in contrast with each of the above examples, although there was no difference in evaluation results as great as in the case of the first example, there was still a significant difference in evaluation results.

According to the present invention, there are provided a hair treatment composition that satisfactorily solves the problems associated with hair treatment agents containing starch phosphates, and a hair treatment method that uses this hair treatment composition.
