Description

Technical Field

[0002] Hair is damaged by the living environment (ultraviolet rays and heat from sunlight), daily hair care activities (friction from shampooing or combing), and chemical treatments (dyeing, perming, etc.). Therefore, hair cosmetics that suppress hair damage are very important, and hair cosmetics that can effectively perform hair care activities without feeling stress are desired.

[0003] In response to such a demand, a hair cosmetic product using a non-gas type foam discharge container instead of a propellant has been proposed.

[0018] Figure 1 These are photographs showing the state of foam quality according to the evaluation criteria used when evaluating foam quality. DETAILED DESCRIPTION

[0019] When a non-gas type foam dispensing container is used for hair application, the hair cosmetic composition is mixed with air in the foam dispensing container, and is squeezed out through the mesh, thereby being discharged in the form of foam. However, there is a problem that when the hair cosmetic composition is discharged from the foam dispensing container in a low temperature environment such as -5°C, poor dispensing occurs. It is found that the poor dispensing is caused by the low stability of the hair cosmetic composition when stored in a low temperature environment, and the mesh is clogged due to precipitation of the components of the composition. Therefore, it is necessary to improve the storage stability of the hair cosmetic composition in a low temperature environment. On the other hand, when it is desired to improve the storage stability in a low temperature environment, the ingredients of the hair cosmetic composition are restricted.

[0020] The technologies of Patent Documents 1 to 5 cannot fully satisfy the requirements of storage stability in a low-temperature environment, foam texture, protection of hair from damage due to friction between hairs during application, and provision of smoothness and suppression of hair tangling during rinsing, and thus need to be improved.

[0021] The present invention relates to a hair cosmetic composition and a hair cosmetic using the hair cosmetic composition, wherein the hair cosmetic composition has excellent storage stability in a low-temperature environment, has excellent texture of foam discharged from a foam discharge container, has excellent protection for hair by preventing damage caused by friction between hairs during application, and can provide good smoothness to hair during rinsing and suppress tangling of hair.

[0022] The present inventors have found that a hair cosmetic composition can solve the above-mentioned problems. The hair cosmetic composition contains or blends a cationic surfactant, an amphoteric surfactant, and one or more selected from a nonionic surfactant, a modified silicone having a cationic group, and a sugar alcohol having 4 or more carbon atoms, wherein the mass ratio of the content or blending amount of the amphoteric surfactant to the content or blending amount of the cationic surfactant is within a predetermined range, and the content or blending amount of the higher alcohol is 0.1 mass % or less.

[0023] That is, the present invention relates to the following [1] and [2].

[0024] [1] A hair cosmetic composition comprising or blending the following component (A), component (B), and component (C):

[0025] Ingredient (A): cationic surfactant,

[0026] Ingredient (B): amphoteric surfactant,

[0027] Component (C): at least one selected from the group consisting of a nonionic surfactant (C1), a modified silicone having a cationic group (C2), and a sugar alcohol having 4 or more carbon atoms (C3),

[0028] The mass ratio of the content or blending amount of the component (B) to the content or blending amount of the component (A) [(B) / (A)] is 0.4 or more and 5 or less,

[0029] The content or blending amount of the higher alcohol is 0.1% by mass or less,

[0030] The hair cosmetic composition is filled in a non-gas type foam dispensing container and used.

[0031] [2] A hair cosmetic composition comprising the hair cosmetic composition described in the above [1] filled in a non-gas type foam discharge container.

[0032] According to the present invention, there can be provided a hair cosmetic composition having excellent storage stability in a low-temperature environment, excellent texture of foam discharged from a foam discharge container, excellent ability to protect hair from damage due to friction between hairs during application, and capable of imparting good smoothness to hair during rinsing and suppressing tangling of hair, and a hair cosmetic composition using the hair cosmetic composition.

[0033] [Hair cosmetic composition]

[0034] The hair cosmetic composition of the present invention (hereinafter, also referred to simply as "hair cosmetic composition") contains or is formulated with the following component (A), component (B), and component (C):

[0035] Ingredient (A): cationic surfactant,

[0036] Ingredient (B): amphoteric surfactant,

[0037] Component (C): at least one selected from the group consisting of a nonionic surfactant (C1), a modified silicone having a cationic group (C2), and a sugar alcohol having 4 or more carbon atoms (C3),

[0038] The mass ratio of the content or blending amount of the component (B) to the content or blending amount of the component (A) [(B) / (A)] is 0.4 or more and 5 or less,

[0039] The content or blending amount of the higher alcohol is 0.1% by mass or less,

[0040] The hair cosmetic composition is filled in a non-gas type foam dispensing container and used.

[0041] In the present invention, storage stability at -5°C is used as an index of "storage stability in a low-temperature environment". If the storage stability at -5°C is excellent, the hair cosmetic composition can be fully used as a hair cosmetic composition to be filled in a non-gas type foam dispensing container even in a usage environment in a cold region. Hereinafter, "storage stability in a low-temperature environment" is simply referred to as "low-temperature stability".

[0042] The reason why the hair cosmetic composition of the present invention achieves the effects of the present invention by having the above-mentioned structure has not been determined, but is presumed as follows.

[0043] The hair cosmetic composition of the present invention contains or is blended with a cationic surfactant as a component (A), an amphoteric surfactant as a component (B), and at least one selected from a nonionic surfactant (C1), a modified silicone having a cationic group (C2), and a sugar alcohol having 4 or more carbon atoms (C3) as a component (C). It is believed that when the mass ratio [(B) / (A)] of the content or blending amount of the component (B) in the hair cosmetic composition to the content or blending amount of the component (A) is within a predetermined range, the solubility of the component (B) is improved by the component (A), and the low-temperature stability is improved. In addition, it is believed that when the mass ratio [(B) / (A)] is within a predetermined range, the texture of the foam discharged from the foam discharging container is improved, the ease of integration of the foam into the hair during application is improved, and the hair can be protected from damage caused by friction between the hairs.

[0044] In the hair cosmetic composition of the present invention, since the content or blending amount of the higher alcohol is below a specific value, it is considered that the components of the composition do not precipitate even in a low-temperature environment, and low-temperature stability is further improved.

[0045] Furthermore, it is considered that the component (C) protects the hair from damage caused by friction between the hairs during application, imparts good smoothness to the hair during rinsing, and suppresses tangling of the hair.
