Description

Hair treatment composition and hair treatment method

The present invention relates to a hair treatment composition and a hair treatment method. More particularly, the present invention relates to hair treatment.

A unique combination of a natural yarn and a synthetic yarn that eliminates the unique problems of blending alkylpolysiloxanes with terminal hydroxy modification such as dimethiconol, and improves hair strength. Hair treatment composition capable of realizing various effects, and this hair treatment composition

The present invention relates to a hair treatment method used for hair. Background art

It is known that a hair treatment agent containing a silicone derivative has an excellent conditioning effect. However, when used for a long period of time, the silicone derivative accumulates on the hair (build-up), and the conditioning effect gradually decreases.

For example, Document 1 below discloses hair cosmetics that contain a silicone derivative and a sugar component. As a technical issue and technical configuration, the above-mentioned problems in the formulation of silicone derivatives can be solved. Related disclosures are not allowed.

[Reference 1] Japanese Patent Application Laid-Open No. 2 0 6 6-8 6 1 1

Thus, proposals that can sufficiently eliminate the deterioration of the conditioning effect due to the accumulation of silicone derivatives on the hair, which is a problem when using a hair treatment composition containing a silicone derivative (especially during continuous use) Not necessarily done. Disclosure of the invention

An object of the present invention is to solve the above-mentioned problems while securing at least the advantages of the blending agent composition containing a silicone derivative.

The inventor of the present application is particularly preferred in the process of pursuing solutions to the above problems through various trials and errors. It has been found that the above problems can be solved by selectively using a terminal hydroxy-modified alkylpolysiloxane, which is a kind of silicone derivative, and combining with an alicyclic polyol such as inositol. Moreover, it has been found that such a blending can provide a surprising effect of “improving hair strength” in addition to solving the above-mentioned problems. The present invention has been completed based on such novel findings.

(First invention)

The first invention of the present application is a hair treatment composition containing the following components (A) and (B).

(A) Component: Alicyclic polyol

(B) component: terminal polyhydroxy-modified alkylpolysiloxane.

In the first invention, the type of the component (A): cycloaliphatic polyol is not particularly limited. For example, diol or hexaol of cyclohexane, dieneol or pentaol of cyclopentane, or these A certain range of oligomers as monomer units is included. Particularly preferred is inositol used in the examples described later.

Inositol is a well-known physiologically active substance, and other alicyclic polyols do not necessarily exhibit the same physiological activity as inositol. However, the unique effects shown below in the first invention are not based on physiological activity, but are thought to be based on the characteristics of the chemical structure of “alicyclic compound having a plurality of hydroxyl groups”. . Therefore, alicyclic polyols other than inositol can be reasonably estimated based on chemical common sense that they exhibit the same effect as inositol.

According to the first invention, since the component (A) and the component (B) are combined with the hair treatment composition, an excellent conditioning effect can be ensured based on the component (B) which is a kind of silicone derivative. At the same time, the component (A) increases the hydrophilicity of the component (B), and the accumulation effect on the hair is suppressed because the component (B) is easily washed away during washing, resulting in a decrease in conditioning effect. Is well prevented.

Furthermore, surprisingly, the hair treatment composition of the first invention improves the hair strength when applied to the hair, both in the (A) component blending system and in the (B) component blending system. 7 067346 was also found to exhibit surprising effects that were not known at all. The reason for this has not been clarified yet, but due to the coating effect of the component (B) on the hair, the component (A) penetrated well into the hair and thus penetrated into the hair. Is estimated to act on the hair structure and improve hair strength.

Furthermore, preferably, the hair treatment composition of the first invention exhibits a good hair strength improving effect even when used for healthy hair, but when this is applied to damaged hair, a particularly remarkable hair strength improving effect is obtained. It was found that it was secured.

Even if the component (B) is added to the hair treatment composition, if the component (A) is not added, the moist feeling of the hair due to the component (B), which is oily, is felt, but the hair becomes sticky and smooth. Chipping, no particular effect of the present invention can be obtained. Even if the component (A) is added to the hair treatment composition, if the component (B) is not added or if a silicone derivative other than the component (B) is added, both the moisture and smoothness of the hair are insufficient. After all, the characteristic effect of the present invention cannot be obtained.

For example, in some documents such as Documents 2 to 4 below, there are cases where inositol is blended with a hair treatment agent or a composition for hair of a similar use. However, the disclosure and suggestion of the technical problem and composition as in the present invention, in which inositol is combined with the component (B) to maintain a good conditioning effect and improve the hair strength, are recognized. I can't.

(1) The blending amount of the component (A) is in the range of 0.05 mass% to 5.0 mass%.

(2) The amount of the component (B) is in the range of 0.1% by mass to 10.0% by mass.

When the blending amount of the component (A) or the component (B) of the hair treatment agent or composition is within the range of the third invention, the effect of the first invention is particularly preferably ensured.

When the blending amount of the component (A) is below the above range, the moisture feeling of the hair due to the component (B) can be felt S, the hair is sticky and the smoothness tends to be insufficient, and the hair strength is improved. The effect tends to be insufficient, and the specific effect of the present invention cannot be obtained sufficiently. (A) Even if the blending amount of the component exceeds the above range, the blending effect described in the first invention is saturated and uneconomical.

Since the (A) component is highly hydrophilic, there is a concern that compatibility with the hydrophobic (B) component may be deteriorated.

When the blending amount of the component (B) is below the above range, it becomes difficult to ensure the conditioning effect, and the hair moisture tends to be insufficient in smoothness and the hair strength improving effect tends to be insufficient. . If the blending amount of component (B) exceeds the above range, problems such as excessive stickiness may occur, and the blending effect described in the first invention will be saturated, which is uneconomical.

Each of the 10 panelists touched the hair bundle after treatment with the hair treatment composition according to each of the above Examples and Comparative Examples by hand to evaluate the firmness of the finished hair. 4 points when there is sufficient harshness, 3 points when there is harshness, 2 points when there is no harshness, and 1 point when there is no harshness did.

For the results of scoring of 10 panelists, the average score is calculated for each of the examples and comparative examples. If the average score is 3.6 or more ◎ (excellent), the average score is 2.6 to 3 · A case of 5 was marked as ◯ (good), an average score of 6 to 2.5 was evaluated as △ (somewhat bad), and an average score of 1.5 or less was rated as X (bad). The results are shown in the “Evaluation of hair” section of “Evaluation” in Tables 1 and ⁵ .

(Evaluation results)

As can be seen from the evaluation results shown in Table 1 and Table 5, Example 1 to Example 4, Example 2 3 to Example 2 6 are very difficult to evaluate in any evaluation item. there were. The slight difference between Example 3 and Example ⁴ in hair strength and harshness depends on the presence or absence of the C component.

On the other hand, regarding Comparative Example 1 to Comparative Example 10, the moisture feeling after drying in Comparative Example 1 to Comparative Example 3 in which the cocoon component was not blended or the component for comparison with the cocoon component was blended See high evaluation However, from the results of other evaluation items, it is clear that none of the comparative examples achieved the specific effects of the present invention.

Furthermore, the following points 1) and 2) can be pointed out from the overall evaluation results shown in Tables 1 and 5.

1) When (A) component is not blended, or (A) component is not blended and (A) component for comparison is blended, there is a moist feeling due to blending of oil, but it is sticky Smoothness

It lacks (softness of hair), and the tensile strength of the hair does not give any harshness.

2) When the component (B) is not blended, even if a component for comparison with the component (B) is blended, the moisture and smoothness (softness) of the hair are not sufficient, and the strength of the hair, Feeling good, ₀

[Second Example Group: Examples related to change of component C and addition of component F]

As shown in Table 2, the component (C) in the formulation of “Example 1” according to the first example group described above was mixed in the same amount by changing the type (Example 5 to Example 11). ) In addition, various components (F) were added to the formulation of “Example 1” relating to the first example group (Examples 12 to 15). These hair treatment compositions had the same dosage form as in Example 1 and the same pH.

When the hair treatment composition according to these examples was used and the same evaluation was performed using the same hair bundle sample as in the case of the first example group, as shown in Table 2, each item was As in the case of Example 1 shown in Table 1, all the items were evaluated as “が”. When comparing these results in more detail, the average score of “feeling of hair harshness” in Example 1 was “3.8”, whereas both components (C) and (F) were compared. In Examples 1 2 to 15 blended together, the evaluation average score was “3.9”.

[Third example group: (A) Examples relating to changes in the amount of ingredients]

As shown in Table 3, the hair treatment agents according to Examples 16 to 19 in which the amount of component (A) in the formulation of “Example 1” according to the first example group described above was changed, respectively. Each composition was prepared according to the same method as in the first example group. These hair treatment compositions had the same dosage form as in Example 1 and the same pH. Example 1 6 to Example 19 Using the hair treatment composition according to 9 and performing the same evaluation using the same hair bundle sample as in the case of the first example group, as shown in Table 3. As in the case of Example 1 shown in Table 1, all items were evaluated as “「 ”. The evaluation average score of “feeling of elasticity of hair” was also not different between Example 16 to Example 19.

[Fourth Example Group: Examples and Comparative Examples for Healthy Hair]

In the case of the first embodiment group, prepare the required number of untreated hair bundles that are 20 cm long human black hair that has not yet undergone decolorization or permanent wave treatment, which is a cause of hair damage. In the same manner as described above, the hair treatment compositions according to Examples 1, 3, 5 and Comparative Examples 1, 4, 9, and 10 were used. Examples using the hair treatment compositions according to Examples 1, 3 and 5 were sequentially numbered as Examples 20, 21 and 22 respectively, and were designated as Comparative Examples 1, 4, 9, and 10 respectively. The examples using the hair wrinkle treating agent composition were sequentially numbered as Comparative Examples 1 1, 1 2, 1 3 and 14, respectively. For these examples and comparative examples, the same evaluation methods and evaluation criteria were evaluated for the same evaluation items as in the case of the first example group.

As a result, as shown in Table 4, Examples 20 0, 21 and 22 are exactly the same as Examples 1 and 3 in the first example group and Example 5 in the second example group. Evaluation results were obtained. On the other hand, Comparative Examples 1 1, 1 2, 1 3 and 14 have relatively higher evaluation ranks than Comparative Examples 1, 4, 9, and 10 of the first example group in many evaluation items. However, in comparison with Examples 2 0, 2 1 and 2 2, there were still significant differences.

Such a result shows that the hair treatment composition according to the present invention has a sufficiently remarkable effect when targeting healthy hair as compared with the prior art, but when treating damaged hair. Means a particularly remarkable effect.
