JP7248999B2 - HAIR CLEANING COMPOSITION AND HAIR CLEANING METHOD - Google Patents

Description

The present disclosure relates to cleaning compositions and cleaning methods.

Hair cleansing compositions are used to wash away dirt from the hair and scalp. As components of the hair cleansing composition, for example, one of anionic surfactants, nonionic surfactants, and amphoteric surfactants may be used alone, or two or more thereof may be used in combination. In addition, in order to improve the feel during rinsing, a complex is formed by adding a cationic surfactant or a cationic polymer to the hair cleansing composition as described above. Furthermore, shampoo compositions containing polyether-modified silicone and the like are also known (see, for example, Patent Document 1).

JP-A-58-74798

However, the prior art as described above is still not fully satisfactory with respect to creaking, hardness and smoothness during rinsing. In addition, by blending the above-mentioned polyether-modified silicone, etc., the squeakiness, hardness, and smoothness during rinsing can be improved to some extent, but another problem such as inhibiting foaming is caused. There is a problem that it is difficult to improve various characteristics in a well-balanced manner.

In one aspect of the present disclosure, it is desirable to provide a cleansing composition and a cleansing method with excellent feel and lather during rinsing.

One aspect of the present disclosure is a cleaning composition containing a linear or branched polyglycerin-modified silicone as component (A). According to the cleansing composition thus constituted, since it contains the component (A), it becomes a cleansing composition with excellent feel and foaming during rinsing.

Another aspect of the present disclosure is a washing method for washing gray hair using the detergent composition of the present disclosure. According to such a washing method, since the cleaning composition as described above is used to wash the gray hair, it is excellent in feel and lather during rinsing, and even gray hair has a good feel during rinsing. can do.

For example, in the case of elderly people, hair quality changes due to an increase in gray hair, and the feel of the hair changes. In the case of gray hair, there is a problem that conventional cleansing compositions are not fully satisfactory in terms of feel during rinsing. On the other hand, the cleansing composition of the present disclosure can improve the texture of white hair during rinsing by blending the components as described above.

The cleaning composition of the present disclosure will be described in more detail below.
(1) Details of detergent composition [Component (A)]
The detergent composition of the present disclosure contains a linear or branched polyglycerin-modified silicone as component (A). In the present disclosure, a polyglycerin-modified silicone is a compound having a structure in which a polyglycerin chain is introduced into a silicone chain. As the polyglycerin-modified silicone, either a linear polyglycerin-modified silicone having a linear silicone chain or a branched polyglycerin-modified silicone having a branched silicone chain may be used, or both may be used in combination. may However, the alkyl-co-modified polyglycerin-modified silicone is difficult to dissolve in water, and it is difficult to obtain a transparent composition. Therefore, for example, when it is desired to constitute a transparent shampoo, it is preferable to use one other than the alkyl co-modified type.

The polymerization number of the polyglycerol chain is usually 2 or more, preferably 3 or more, and usually 5 or less, preferably 4 or less. Specific examples of polyglycerin-modified silicones include polyglyceryl-3 disiloxane dimethicone and polyglyceryl-3 polydimethylsiloxyethyl dimethicone.

Commercially available products can be used as such polyglycerin-modified silicone. For example, "KF-6100" manufactured by Shin-Etsu Chemical Co., Ltd. can be used as polyglyceryl-3 disiloxane dimethicone. As polyglyceryl-3 polydimethylsiloxyethyl dimethicone, "KF-6104" manufactured by Shin-Etsu Chemical Co., Ltd. can be used.

The amount of component (A) to be blended may be appropriately adjusted, but is, for example, 0.01% by mass to 5% by mass, preferably 0.05% by mass to 3% by mass, based on the total amount of the detergent composition. %, more preferably 0.1 mass % to 1 mass %. By setting the blending amount of component (A) to 0.01% by mass or more, the feel during rinsing is improved. The feeling during rinsing can be improved by setting the amount of component (A) to 0.05% by mass or more. can be made even better. In addition, by setting the amount of component (A) to 5% by mass or less, it is possible to suppress overconditioning (that is, excessive adsorption and accumulation of components), thereby preventing, for example, hardening of the hair. can be suppressed. The effect of suppressing overconditioning is further improved by setting the amount of component (A) to 3% by mass or less, and is further improved by setting the amount of component (A) to 1% by mass or less.

By blending component (A), squeakiness, hardness, and smoothness during rinsing can be improved without excessively inhibiting lathering, unlike the case where polyether-modified silicone or the like is blended.

By setting the amount of component (C) to be 1% by mass or more, good foaming during use can be achieved. Further, by setting the blending amount of component (C) to 1% by mass or more, it is possible to suppress a decrease in viscosity. If you want to improve the effect of suppressing foaming and viscosity decrease during use, the amount of component (C) may be 3% by mass or more, and if you want to further improve the effect of suppressing viscosity decrease, component (C ) may be 5% by mass or more. Also, by setting the amount of component (C) to be 20% by mass or less, the feel during rinsing is improved. The feel during rinsing is improved by setting the blending amount of component (C) to 15% by mass or less, and is further improved by setting the blending amount of component (A) to 10% by mass or less.

(2) Experimental Examples Next, embodiments of the present invention will be described more specifically with reference to some examples and comparative examples.

A detergent composition containing each component shown in Tables 1 and 2 below was prepared. Each numerical value corresponding to each component shown in Tables 1 and 2 indicates the compounding amount of each component, and the unit is % by mass. In Tables 1 and 2, the symbols "A", "B", "C", "D1", and "D2" added to the left of each component indicate that each component in the table corresponds to the component (A ), (B), (C), (D1), and (D2). The code "not A" appended to the left of each component indicates that the component marked with the code is a component for comparison with the component (A), and the code "not B" is the code indicates that it is a component for comparison with component (B).

As an experimental procedure, 20 female subjects with highly damaged hair who had undergone repeated hair dyeing or bleaching treatments were treated as subjects, and appropriate amounts of each of the hair cleansing compositions shown in Tables 1 and 2 were applied to the hair of each subject. After application, the hair was washed according to a conventional method. The hair was then rinsed with water. Then, each cleansing composition was evaluated for "foaming" and "feel during rinsing" by the following methods.

[foaming]
Of the 20 subjects, the number of subjects who evaluated that foaming is good (excellent foaming property) is "excellent: AA" when 16 or more, and "good: A" when 11 to 15 people. The case of 6 to 10 people was evaluated as "Normal: B", and the case of 5 or less people was evaluated as "Poor: C" and evaluated on a scale of 4.

[Feeling when rinsing]
Of the 20 subjects, the number of subjects who evaluated that the finger combability during rinsing was good was "excellent: AA" when 16 or more, and "good: A" when 11 to 15, and 6. A case of up to 10 people was evaluated as "Normal: B", and a case of 6 or less people was evaluated as "Poor: C" and evaluated in 4 stages.

As a comprehensive evaluation, if at least one of the above two evaluation items has an evaluation result of "AA" or "A", and there is no evaluation item that has an evaluation result of "C", it is considered a pass. , and those other than the pass were regarded as fail. As shown in Tables 1 and 2, in Examples 1 to 21, the evaluation results for "foaming" and "feel during rinsing" were "AA", "A", or "B". .

On the other hand, Comparative Example 1 is an example in which the component (A) referred to in the present disclosure is not included. However, in Comparative Example 1, the evaluation result of "feel during rinsing" was "C". Comparative Example 2 is an example in which polyethylene glycol-11 methyl ether dimethicone was blended instead of component (A). However, in Comparative Example 2, the evaluation result of "foaming" was "C". Comparative Example 3 is an example in which dimethicone was blended instead of component (A). However, in Comparative Example 3, the evaluation result of "foaming" was "C". Further, in the case of Comparative Example 3, turbidity occurred in the cleansing composition, and the transparency of the cleansing composition decreased. Therefore, in the case of Comparative Example 3, marketability as a detergent composition is low as it is. Therefore, in order to compensate for this, it becomes necessary to add an additional ingredient that, for example, results in an opaque pearly shampoo. In other words, when it is desired to prepare a transparent shampoo composition, it was found that the formulation of Comparative Example 3 cannot be used.

Example 2 is an example in which an amino acid-based anionic surfactant different from that in Example 1 is used as the component (B). In both Examples 1 and 2, the evaluation results of "foaming" and "feel during rinsing" were "AA". Example 3 is an example in which an amphoteric surfactant different from that in Example 1 is used as component (C). In both Examples 1 and 3, the evaluation results of "foaming" and "feel during rinsing" were "AA".

In Example 1, both (D1) a nonionic surfactant that is liquid at room temperature and (D2) a nonionic surfactant that is solid at room temperature are blended as the component (D) referred to in the present disclosure. In contrast, Example 4 is an example in which the component (D) referred to in the present disclosure is not included. However, even in the case of Example 4, the evaluation results of "foaming" and "feel during rinsing" were "A". In addition, Example 5 contains (D2) a nonionic surfactant that is solid at room temperature as the component (D), but does not contain (D1) a nonionic surfactant that is liquid at room temperature. is. However, even in the case of Example 5, the evaluation result of "foaming" was "AA" and the evaluation result of "feel during rinsing" was "A". Example 6 is an example in which component (D) contains (D1) a nonionic surfactant that is liquid at room temperature, but does not contain (D2) a nonionic surfactant that is solid at room temperature. . However, even in the case of Example 6, the evaluation result of "foaming" was "A", and the evaluation result of "feel during rinsing" was "AA".

Examples 7 to 10 are examples in which the blending amount of the component (A) was changed from that of Example 1. Even in the case of Examples 7 to 10, the evaluation result of "foaming" was "AA", and the evaluation result of "feel during rinsing" was "AA" or "A". Both Examples 7 and 8 had good evaluation results, but when both were compared, Example 7 showed more favorable results. Both Examples 9 and 10 had good evaluation results, but when both were compared, Example 10 showed more favorable results.

Examples 11 and 12 are examples in which the blending amount of the component (B) was changed from that of Example 1. Also in the case of Example 11, the evaluation result of "foaming" was "AA", and the evaluation result of "feel during rinsing" was "A". In the case of Example 12, the evaluation result of "foaming" was "A", and the evaluation result of "feel during rinsing" was "AA". Examples 13 and 14 are examples in which the blending amount of the component (C) was changed from that of Example 1. In the case of Example 13, the evaluation result of "foaming" was "AA", and the evaluation result of "feel during rinsing" was "A". In the case of Example 14, the evaluation result of "foaming" was "A", and the evaluation result of "feel during rinsing" was "AA".

Examples 15 to 17 are examples in which the blending amount of the component (D2) was changed from that of Example 1. In the case of Example 15, the evaluation result of "foaming" was "AA", and the evaluation result of "feel during rinsing" was "AA". In the case of Example 16, the evaluation result of "foaming" was "AA", and the evaluation result of "feel during rinsing" was "A". In the case of Example 17, the evaluation result of "foaming" was "A", and the evaluation result of "feel during rinsing" was "AA". Examples 18 to 20 are examples in which the compounding amounts of some of the components (A) to (D) were changed from those of Example 1. In each of Examples 18 to 20, the evaluation result of "foaming" was "AA", and the evaluation result of "feel during rinsing" was "AA".

Example 21 is an example that does not include component (B) as referred to in this disclosure. In the case of Example 21, the evaluation result of "foaming" was "B", and the evaluation result of "feel during rinsing" was "AA". Therefore, although Example 21 also passed the overall evaluation, it can be seen that it is preferable to incorporate the component (B) in order to further improve foaming. Example 22 is an example in which a sulfuric acid-based anionic surfactant was blended instead of the component (B) (that is, an amino acid-based anionic surfactant) referred to in the present disclosure. In the case of Example 22, the evaluation result of "foaming" was "AA", and the evaluation result of "feel during rinsing" was "B". Therefore, although Example 22 also passed the overall evaluation, it can be seen that the feel during rinsing is better when the component (B) is blended.

In Example 22, the entire amount of component (B) exemplified in Examples 1 and 2 was replaced with a sulfuric acid-based anionic surfactant. However, component (B) and a sulfuric acid-based anionic surfactant can be used in combination. As an intermediate formulation between Example 1 and Example 22, for example, the blending amount of the component (B) is 3.75% by mass, and the blending amount of the sulfuric acid-based anionic surfactant is 3.75% by mass. (That is, the sulfuric acid-based anionic surfactant is 50% by mass of the total amount of the anionic surfactants.). In this case, the feel during rinsing is improved over that of Example 22 and approaches that of Example 1.

In order to further improve the feeling during rinsing compared to the above intermediate formulation, the blending amount of component (B) is set to 5.625% by mass and the blending amount of the sulfuric acid-based anionic surfactant is set to 1.875% by mass. (That is, the sulfuric acid-based anionic surfactant is 25% by mass of the total amount of the anionic surfactants.). In this case, the feel during rinsing is further improved over the intermediate formula described above, and approaches Example 1.

In other words, when the sulfuric acid-based anionic surfactant is suppressed to 50% by mass or less in the total amount of all anionic surfactants blended in the detergent composition, the feel during rinsing is improved. If the sulfuric acid-based anionic surfactant is 25% by mass or less, the feeling during rinsing becomes better, and if the sulfuric acid-based anionic surfactant is not blended (that is, Example 1 , 2), the feel during rinsing is even better.

Example 23 is an example that does not contain component (C) as referred to in this disclosure. In the case of Example 23, the evaluation result of "foaming" was "B", and the evaluation result of "feel during rinsing" was "AA". Therefore, although Example 23 also passed the overall evaluation, it can be seen that it is preferable to incorporate the component (C) in order to further improve foaming.

Furthermore, in the case of the cleansing composition of Example 1, the "feel during rinsing" was good for both black hair and gray hair. However, in the case of the cleansing composition of Comparative Example 2, especially in the case of gray hair, there was a tendency that the "feel during rinsing" was not good. Comparative Example 2 differs from Example 1 in that polyethylene glycol-11 methyl ether dimethicone is blended instead of component (A) and that component (B) is not blended. Therefore, the cleaning composition of Example 21 was also tested. As a result, the cleansing composition of Example 21 had a good "feel during rinsing" for both black hair and gray hair. Therefore, from these results, it is considered important to blend the component (A) in order to improve the "feel during rinsing" of gray hair. In addition, it is believed that by blending component (B) in addition to component (A), both "foaming" and "feel during rinsing" can be improved.
