Description

[Technical field]

[0001] The present invention relates to a hair cleansing composition or a fabric cleansing composition for head accessories. [Background technology]

[0002] Hair is damaged by the living environment (ultraviolet rays and heat from sunlight), daily hair care actions (friction from washing and brushing), and chemical treatments (coloring, perms, etc.). Furthermore, hair condition tends to deteriorate due to careless hair care actions or omission of necessary steps, as daily hair care actions take time and effort. Therefore, there is a demand for hair cosmetics that allow efficient and stress-free hair care actions.

[0003] Among conventional hair cosmetics, hair cleansing agents are required to have improved operability, such as lathering on hair, ease of application, and rinsing, from the viewpoints of ease of hair care and reducing hair damage by preventing hair tangling. In response to such demands, hair cleansing agents with improved operability and foam-type hair cleansing agents that are discharged from a non-gas type foam-discharging container that does not use a propellant have been proposed. Foam-type hair cleansing agents in particular have the characteristics of being easy to apply because they foam well and are quickly absorbed into the hair, and leaving little residue behind after rinsing. In addition, non-gas type foam-discharging containers have a smaller environmental impact when disposed of than aerosol containers that use propellants, and there is no need to consider corrosion prevention for metal containers, so there is a high degree of freedom in the composition of the contents.

[0004] For example, Patent Document 1 discloses a shampoo composition that contains an α-olefin sulfonate, a coconut oil fatty acid methyl taurate salt, an amphoteric surfactant, two or more water-soluble polymers having a cationic group, and a cationized guar gum, with the objective of obtaining a shampoo composition that is excellent in foam elasticity, smoothness during rinsing, moist finish, lack of clumping, and softness. Patent Document 2 discloses a liquid detergent composition filled in a non-gas-type foam-ejecting container, which has an objective of providing a liquid detergent composition that is free from clogging, produces creamy and stable foam, has excellent foam-forming properties even at low temperatures, and provides a refreshing feeling during rinsing and a moist feeling after towel drying. The liquid detergent composition is filled in a foam-ejecting container and contains a higher fatty acid salt, one or more amphoteric surfactants selected from carbobetaine-type amphoteric surfactants and sulfobetaine-type amphoteric surfactants, a polyoxyethylene sorbitan fatty acid ester that is solid at 30°C, and a polyhydric alcohol. Patent Document 3 discloses a hair wash composition for use in a non-aerosol foam-discharging container, which has an object to provide a hair wash composition for use in a non-aerosol foam-discharging container that does not clog when discharged in foam form from the container, produces a creamy and stable foam, and also has an excellent conditioning effect after washing. The hair wash composition contains an anionic surfactant, an amphoteric surfactant, a lower alcohol and / or a polyhydric alcohol, a cationic polymeric compound, and at least one finish-improving ingredient selected from the group consisting of oils, silicones, protein hydrolysates, amino acids, and cationic surfactants, and has a viscosity of 30 mPa s or less.

[0005] [Patent Document 1] JP 2018-172338 A [Patent Document 2] JP 2014-156537 A [Patent Document 3] JP 2005-187359 A Summary of the Invention [Problem to be solved by the invention]

[0006] When applying the detergent composition to hair or fibers for head ornaments such as wigs using a non-gas type foam discharge container, the detergent composition used for hair or fibers for head ornaments is mixed with air in the foam discharge container and extruded through a mesh to be discharged in the form of foam. However, when the detergent composition stored in a low temperature environment such as -5°C is discharged from the foam discharge container, there is a problem that discharge failure occurs. It has been found that this discharge failure is caused by the low stability of the detergent composition when stored in a low temperature environment, and the precipitation of the components of the detergent composition causes clogging of the mesh. Therefore, there is a demand for improvement in the storage stability of the hair detergent composition or the fiber detergent composition for head ornaments in a low temperature environment and the texture of the foam discharged from the foam discharge container. On the other hand, in the case of a hair wash composition or a fiber wash composition for head ornament products discharged in foam form, there is a limit to the total amount of surfactants to be blended in order to maintain the foam quality at the time of discharge. Therefore, for users with long hair or a large amount of hair, or when the fibers for head ornament products are long or the amount of fibers for head ornament products in a head ornament product is large, the feel of foaming during washing of the hair or fibers for head ornament products, smoothness during rinsing of the hair or fibers for head ornament products, etc., tends to be insufficient, and the solubility of oils and fragrances cannot be sufficiently ensured, causing turbidity in a low-temperature environment and decreasing storage stability in a low-temperature environment. The technologies disclosed in Patent Documents 1 to 3 do not achieve both a good balance between the stability (non-precipitation) and dischargeability of the detergent in a low-temperature environment and the usability (foam performance, rinsing performance, and finger-combability after drying), and improvements are needed.

[0007] The present invention aims to provide a hair wash composition or a fiber wash composition for head ornament products that has excellent storage stability in a low-temperature environment and excellent foam texture when discharged from a foam-dispensing container, and also has good foaming properties when washing hair or fibers for head ornament products, and is capable of imparting smoothness when rinsing hair or fibers for head ornament products and good finger-combability after drying to the hair or fibers for head ornament products, and a hair wash or fiber wash composition for head ornament products that uses the wash composition. [Means for solving the problem]

[0008] The present inventors have found that the above-mentioned problems can be solved by a hair wash composition or a fabric wash composition for head accessories which is filled into a foam-discharging container for use and which contains two or more types of non-sulfate anionic surfactants, a nonionic surfactant, a cationic polymer (excluding polyquaternium-7), and a polyhydric alcohol, wherein the content of the cationic polymer is less than a specified value and the content of the polyhydric alcohol is equal to or greater than a specified value. That is, the present invention provides the following [1] and [2]. [1] The following components (A) to (D): (A) two or more non-sulfate anionic surfactants; (B) a nonionic surfactant, (C) cationic polymers (excluding polyquaternium-7), (D) Polyhydric alcohol Contains The content of component (C) is less than 0.20% by mass, A hair cleansing composition or a fabric cleansing composition for head accessories, which is filled into a foam-discharging container and used, and contains 5 mass % or more of component (D).

[0009] According to the present invention, it is possible to provide a hair wash composition or a fiber wash composition for head ornament products which has excellent storage stability in a low-temperature environment and excellent foam texture when discharged from a foam-dispensing container, and which foams well when washed with hair or fibers for head ornament products, and which can impart smoothness when rinsing the hair or fibers for head ornament products and good finger-combability after drying, and a hair wash or fiber wash composition for head ornament products which uses said wash composition.

In the present invention, "comprising component X" or "containing component X" also means "comprising component X blended therein." 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 cleaning composition can be suitably used in a non-gas type foam-discharging container even in a usage environment in a cold region. Hereinafter, "storage stability in a low-temperature environment" is also simply referred to as "low-temperature stability". In addition, in the present invention, the "texture of foam discharged from a foam discharge container in a low-temperature environment" is an index of the texture (foam quality) of foam discharged from a non-gas type foam discharge container at 5° C.
