Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic composition. [Background technology]

[0002] Hair is easily damaged by the effects of ultraviolet rays, heat from a hair dryer, brushing, washing, etc., and becomes difficult to run your fingers through. Furthermore, while the use of perms, hair coloring, bleaching, etc. has become common in recent years, hair damage such as dryness and loss of elasticity caused by these chemical treatments has also become a problem. Various hair cosmetics have been disclosed to prevent hair damage and improve hair feel (Patent Document 1, Patent Document 2). Although technology for giving hair bounce, strength, and manageability is improving year by year, there is a demand for hair cosmetics that have better effects and that feel better to use, and further progress is desired.

(4) The hair cosmetic composition according to any one of (1) to (3), which is filled in a foam-dispensing container. [Effects of the Invention]

[0006] The present invention can provide a hair cosmetic composition which is less likely to clog even when filled into a foam-dispensing container and which has an excellent effect of imparting softness, luster and moisture to hair. DETAILED DESCRIPTION OF THE INVENTION

[0007] The sulfosuccinate ester anionic surfactant used in the present invention can be any anionic surfactant that is ester-bonded with sulfosuccinic acid, and is not particularly limited.Specifically, as the sulfosuccinate diester anionic surfactant, diamyl sulfosuccinate, diisodecyl sulfosuccinate, diisostearyl sulfosuccinate, dioleyl sulfosuccinate, diethylhexyl sulfosuccinate, dicapryl sulfosuccinate, distearyl sulfosuccinate, dicetyl sulfosuccinate, ditridecyl sulfosuccinate, dilauryl sulfosuccinate and salts thereof can be mentioned, and as the sulfosuccinate monoester anionic surfactant, polyoxyethylene alkyl sulfosuccinate and salts thereof can be mentioned.

[0008] The sulfosuccinate ester-based anionic surfactant is preferably blended in a total amount of 0.01 to 0.5% by mass based on the total amount of the hair cosmetic composition of the present invention. If the blending amount is less than 0.01% by mass, a sufficient hair softening effect may not be obtained. If the blending amount is more than 0.5% by mass, clogging may occur when the foam dispenser is filled.

[0009] Commercially available sulfosuccinate ester-based anionic surfactants can be used. For example, examples of sulfosuccinate (C12-14) Palace-2Na (displayed on cosmetics) include Viewlight ESS (manufactured by Sanyo Chemical Industries, Ltd.) and Kohacool L-400 (manufactured by Toho Chemical Industry Co., Ltd.), examples of laureth sulfosuccinate disodium (displayed on cosmetics) include REWOPOL SB FA 30 B (manufactured by Evonik Operations), Viewlight LSS (manufactured by Sanyo Chemical Industries, Ltd.), Rikamild ES-100 (manufactured by New Japan Chemical Co., Ltd.), and Rikamild ES-200 (manufactured by New Japan Chemical Co., Ltd.), and examples of diethylhexyl sodium sulfosuccinate (displayed on cosmetics) include NIKKOL OTP-75 (manufactured by Nikko Chemicals Co., Ltd.), TEGO Sulfosuccinate DO 75 (manufactured by Evonik Operations), and Rikasurf G-30 (manufactured by New Japan Chemical Co., Ltd.), etc. In the hair cosmetic composition of the present invention, it is preferable to use one or two selected from (C12-14) Pareth-2Na sulfosuccinate and (C12-14) Laureth-2Na sulfosuccinate, from the viewpoints of low irritation and resistance to clogging when filled into a foam-dispensing container, and it is most preferable to use (C12-14) Pareth-2Na sulfosuccinate.

[0010] The polyoxypropylene diglyceryl ether used in the present invention is not particularly limited, and examples thereof include polyoxypropylene (9) diglyceryl ether (SY-DP9, manufactured by Sakamoto Pharmaceutical Co., Ltd.) and polyoxypropylene (14) diglyceryl ether (SY-DP14T, manufactured by Sakamoto Pharmaceutical Co., Ltd.).

[0011] The polyoxypropylene diglyceryl ether is preferably blended in a total amount of 1 to 10% by mass based on the total amount of the hair cosmetic composition of the present invention. If the blending amount is less than 1% by mass, a sufficient hair softening effect may not be obtained. If the blending amount is more than 10% by mass, clogging may occur when the foam dispenser container is filled with the polyoxypropylene diglyceryl ether.

[0012] The hair cosmetic composition of the present invention can contain trimethylglycine. By incorporating trimethylglycine, a hair repair effect can be expected. When trimethylglycine is incorporated, the amount of trimethylglycine incorporated is preferably 1 to 10% by mass in total based on the total amount of the hair cosmetic composition of the present invention.

[0013] The hair cosmetic composition of the present invention may contain a phosphorylcholine group-containing polymer, which can impart an antistatic effect to the hair cosmetic composition.

[0014] Any phosphorylcholine group-containing polymer that can be incorporated into cosmetics can be used, and they may be used alone or in combination of two or more. Specific examples of such phosphorylcholine group-containing polymers include, in terms of cosmetic ingredient name, Polyquaternium-51 (2-methacryloyloxyethyl phosphorylcholine-butyl methacrylate copolymer), Polyquaternium-65 (2-methacryloyloxyethylene phosphorylcholine-butyl methacrylate-sodium methacrylate copolymer), Polyquaternium-64 (2-methacryloyloxyethyl phosphorylcholine-2-hydroxy-3-methacryloyloxypropyltrimethylammonium copolymer), and Polyquaternium-61 (2-methacryloyloxyethyl phosphorylcholine-stearyl methacrylate copolymer). In the present invention, Polyquaternium-61 is preferred due to its antistatic effect.

[0015] When a phosphorylcholine group-containing polymer is blended, the blending amount thereof is preferably 0.001 to 0.5% by mass based on the total amount of the hair cosmetic composition of the present invention.

[0016] The hair cosmetic of the present invention is preferably used by filling the above-mentioned hair cosmetic in a container equipped with a foam discharge mechanism. A container equipped with a foam discharge mechanism refers to a non-aerosol (also called non-gas) type container other than an aerosol type foam discharge container that uses a propellant, and is a container that can discharge the hair cosmetic filled in the discharge container in a foam state by mixing it with air and passing it through a porous membrane. Specific examples include pump foamers and squeeze foamers.

[0017] In addition, one or more porous membranes are provided inside the discharge container, and the number of holes in the membrane is not particularly limited, but from the viewpoint of achieving fine foam quality, a mesh size of 100 to 400 mesh is preferred, and a mesh size of 150 to 300 mesh is more preferred.

[0018] In addition to the above-mentioned components, the hair cosmetic composition of the present invention may contain optional components used in ordinary hair cosmetics to the extent that the effects of the present invention are not impaired. Specific examples of such optional components include surfactants, thickeners, preservatives, fragrances, moisturizers, antioxidants, anti-inflammatory agents, and antibacterial agents.

[0019] The hair cosmetic composition of the present invention can be produced by a conventional method and may be in the form of a liquid, cream, or the like, and may be filled into various containers, such as foam-discharging containers, aerosol containers, plastic containers, aluminum tube containers, and pouch containers.

[0020] The hair cosmetic composition of the present invention can be made into products such as leave-on treatments and hair styling agents. [Example]

[0021] The present invention will be described in more detail below with reference to examples, but the scope of the present invention is not limited thereto. The blending amounts are in mass % unless otherwise specified.

[0022] The formulations of hair cosmetics according to the examples of the present invention and comparative examples are shown in Table 1. The hair cosmetics were prepared according to a standard method, filled into a pump former for use evaluation (Takemoto Co., Ltd., two sheets of 100 mesh x 200 mesh), and subjected to evaluation.

[0023] Usability evaluation (hair flexibility, shine, moisture, ease of use) A usability test was conducted by three expert panelists. First, each panelist thoroughly washed and rinsed their hair with their usual shampoo, dried it with a hair dryer, and then applied an appropriate amount of the hair cosmetic composition shown in Table 1 and worked it into the entire hair. Absolute evaluations were made of the hair's softness, luster, moisture, and usability according to the following criteria, and the evaluations were made by consensus. <Judgment criteria> ○:Good △: I can't say either way ×: Bad
