Description

[Technical Field]

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

[0002] In recent years, amino acid-based surfactants, which are mild and cause little irritation to the scalp and skin, have become popular on the market as cleansing ingredients in detergents for hair or fibers used in headwear products, and formulations using carboxylic acid-based surfactants, including acyl amino acids, are on the rise.

[0003] For example, Patent Document 1 discloses a cleanser composition that is mild to the skin or hair and that can suppress the elution of intercellular lipids even when sufficient foaming is achieved by combining an anionic surfactant selected from acylated amino acids, acyltaurines, polyoxyalkylene alkyl ether carboxylic acids, and the like with an amphoteric surfactant or a specific nonionic surfactant. Patent Document 2 discloses a detergent composition that combines at least one of polyhydric alcohols and sugars with an anionic surfactant and an amphoteric surfactant, and that has excellent antiseptic properties, good foaming properties, and other properties that make it easy to use.

[0005] However, carboxylic acid surfactants are not sufficiently soluble in water, and they often precipitate during formulation, causing the cleaning composition to become cloudy. Therefore, when a carboxylic acid surfactant is added, it is difficult to prepare a transparent and stable cleaning composition, and stability at low temperatures is an issue, in particular. Furthermore, compared to surfactants such as laureth sulfate, which have high foaming and stability, carboxylic acid surfactants have poor foaming properties, which also poses a challenge in improving the cleaning properties of the cleaning composition. That is, a cleaning composition using a carboxylic acid surfactant has not yet been realized that ensures low-temperature stability while providing good foaming during cleaning, good creaminess of the foam, and good smoothness during rinsing.

[0006] The present invention relates to a hair wash composition or a fiber wash composition for head accessories, which contains a carboxylic acid surfactant and has excellent low-temperature stability, and when applied to hair or fibers for head accessories such as wigs, is excellent in terms of foaming during washing, creaminess of the foam, and smoothness during rinsing. [Means for solving the problem]

[0007] The present inventors have discovered that the above-mentioned problems can be solved by incorporating an alkyl glucoside, a specific sulfonic acid-based anionic surfactant, an alkyl ether carboxylic acid or a salt thereof, and an amphoteric surfactant in a specific combination. That is, the present invention provides: The following components (A) to (D): (A) alkyl glucoside, (B) a sulfonic acid-based anionic surfactant containing an acyltaurine salt; (C) an alkyl ether carboxylic acid or a salt thereof, (D) amphoteric surfactants, Contains The content of the component (A) is 2.0% by mass or more, and The present invention relates to a hair wash composition or a fabric wash composition for head accessories, in which the content of an acyltaurine salt in component (B) is 25% by mass or more. [Effects of the Invention]

[0008] The hair wash composition or the fiber cleanser composition for head accessories of the present invention has excellent low-temperature stability, and when applied to hair or fibers for head accessories such as wigs, it is possible to provide a hair wash composition or a fiber cleanser composition for head accessories that is good in terms of foaming during washing, creaminess of the foam, and smoothness during rinsing. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is a diagram showing the evaluation criteria for the appearance (stability) of hair wash compositions or fabric wash compositions for head accessories in the examples. DETAILED DESCRIPTION OF THE INVENTION

[0010] [Hair cleansing composition or fabric cleansing composition for head accessories] The hair wash composition or the fiber wash composition for head accessories of the present invention comprises the following components (A) to (D): (A) alkyl glucoside, (B) a sulfonic acid-based anionic surfactant containing an acyltaurine salt; (C) an alkyl ether carboxylic acid or a salt thereof, and (D) amphoteric surfactants, Contains The content of the component (A) is 2.0% by mass or more, and The hair wash composition or the fabric wash composition for head accessories has an acyltaurine salt content of 25 mass% or more in component (B). The hair wash composition or the fabric cleanser composition for head accessories of the present invention has the above-mentioned configuration, and is a hair wash composition or a fabric cleanser composition for head accessories that has excellent low-temperature stability, good foaming during cleansing, good creaminess of the foam, and good smoothness during rinsing.

[0011] <Definition> In this specification, the hair cleanser composition and the fiber cleanser composition for head accessories of the present invention may be collectively referred to as the "cleaner composition." In the present invention, "hair" primarily refers to human head hair, but also includes hair that has been cut off from the human head. In this specification, the term "headwear product" refers to, for example, hair wigs, hairpieces, weaving, hair extensions, braided hair, hair accessories, doll hair, and the like. In this specification, the term "fiber for head accessories" refers to fibers used in the head accessories. In the present invention, "comprises component X" or "contains component X" also means "composed of component X." 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 composition can be suitably used as a hair wash composition or a fiber cleanser composition for head accessories even in usage environments in cold regions. Hereinafter, "storage stability in a low-temperature environment" will also be simply referred to as "low-temperature stability." Furthermore, in the present invention, "hair or fibers for head accessories" is also referred to as "hair, etc.", "hair washing or cleaning fibers for head accessories" is also referred to as "hair washing, etc." or simply "cleaning," and "smoothness of hair or fibers for head accessories when rinsing" is also referred to as "smoothness of hair, etc. when rinsing" or simply "smoothness when rinsing."

[0012] The reason why the cleaning composition of the present invention has the above-described structure and thereby exhibits the effects of the present invention is not clear, but is presumed as follows. The detergent composition of the present invention contains component (A) a sulfonic acid-based anionic surfactant containing 2.0% by mass or more of an alkyl glucoside, component (B) a sulfonic acid-based anionic surfactant containing 25% by mass or more of an acyltaurine salt, component (C) an alkyl ether carboxylic acid or a salt thereof, and component (D) an amphoteric surfactant. By including component (C), the cleanser composition can impart cleansing properties while being gentle on the scalp and skin. More specifically, when washing hair with the cleanser composition, dirt such as sebum is trapped in micelles containing component (C), a carboxylic acid surfactant, and the dirt trapped in the micelles is washed away during rinsing. On the other hand, it is thought that in a low-temperature environment below the Krafft point, the packing between the surfactants of component (C) becomes dense, hydrate crystals precipitate, and stability (transparency) decreases. However, in the present invention, by blending components (A) and (B), which are surfactants with high solubility in water, component (C) forms mixed micelles with other surfactants, even in a low-temperature environment, which is thought to lower the Krafft point and improve low-temperature stability. Furthermore, by blending component (A), component (B), and component (D) together, it is believed that good properties can be imparted to the product, such as foaming during cleansing, creaminess of the foam, and smoothness during rinsing, while maintaining the improved low-temperature stability.

Regenerated collagen fibers can be produced by known techniques. The composition of regenerated collagen fibers does not need to be 100% collagen, and they may contain natural polymers, synthetic polymers, additives, etc. to improve quality. Furthermore, regenerated collagen fibers may be post-processed or post-treated. Filaments are preferred as the form of regenerated collagen fibers. Filaments are generally removed from bobbins or boxes. In addition, filaments emerging from the drying process in the regenerated collagen fiber production process can also be used directly.

[0074] The present invention will be described below with reference to examples, but the present invention is not limited to the scope of the examples.

[0075] [Examples 1 to 46, Comparative Examples 1 to 8] (Preparation and Evaluation of Cleaning Compositions) Each cleaning composition was prepared according to the formulation shown in Tables 1 to 6. Sodium hydroxide (caustic soda) was added as a pH adjuster to adjust the pH to the values ​​shown in Tables 1 to 5. The pH was measured by diluting the cleaning composition with purified water to 5% (20-fold dilution) to obtain an aqueous dispersion, and measuring the pH at 25°C with a pH meter (HM-42X, manufactured by DKK-TOA Corporation).

[0076] The resulting cleanser compositions of each example were evaluated for appearance, foaming during cleansing, creaminess of the foam during cleansing, and smoothness during rinsing using the methods described below. The results are shown in Tables 1 to 6. The blending amount (mass %) of each component shown in the table is the amount of active ingredient.

[0077] <Appearance immediately after preparation (appearance at room temperature)> Approximately 100 mL of the detergent composition obtained in each example was filled into a 110 mL transparent glass bottle, sealed, and the appearance was visually observed at room temperature (25°C) and evaluated according to the following four-level evaluation criteria. A reference diagram for these evaluation criteria is shown in Figure 1. [Evaluation criteria] A: Transparent B: Slightly cloudy but almost transparent C: Cloudy D: Cloudy, or precipitation, separation or sedimentation is observed

[0078] <Low temperature stability (appearance at -5°C)> Approximately 100 mL of the detergent composition obtained in each example was filled into a 110 mL transparent glass bottle, which was then sealed and left to stand in a low-temperature, constant-humidity chamber at -5°C for 3 days. The appearance was visually observed and evaluated according to the following four-level evaluation criteria. [Evaluation criteria] A: Transparent B: Slightly cloudy but almost transparent C: Cloudy D: Cloudy, or precipitation, separation or sedimentation is observed

[0079] <Foaming during washing> A Japanese woman's hair bundle, 30 cm long, 6 cm wide, and weighing 25 g, was thoroughly rinsed with warm water at 40°C. Then, 1.0 g of each cleanser composition was evenly applied to the hair, and the hairs were gently rubbed together for approximately 30 seconds to create a lather. The lathering quality was evaluated by a panel of three experts using the following five-point scale (the evaluation criteria were as follows: Example 10 was rated "5", Comparative Example 3 was rated "1", and the intermediate score was rated "3"). The evaluation values ​​shown in Tables 1 to 6 are the average values ​​of three expert panels. [Evaluation criteria] 5: Good foaming 4: Slightly good foaming 3: Neither 2: Slightly poor foaming 1: Poor foaming

[0080] <Creamy foam when washing> A Japanese woman's hair bundle, 30 cm long, 6 cm wide, and weighing 25 g, was thoroughly rinsed with warm water at 40°C. Then, 1.0 g of each cleanser composition was evenly applied to the hair, and the hairs were gently rubbed together for approximately 30 seconds to create a lather. The resulting lather was evaluated by a panel of three experts on a sensory scale of 5 (Example 10 was rated "5," Comparative Example 3 was rated "1," and the intermediate score was rated "3"). The evaluation values ​​shown in Tables 1 to 6 are the average values ​​of three expert panels. [Evaluation criteria] 5: Creamy foam 4: Slightly creamy foam 3: Neither 2: Not very creamy foam 1: Not creamy foam

[0081] <Smoothness when rinsing> A Japanese woman's hair bundle, 30 cm long, 6 cm wide, and weighing 25 g, was thoroughly rinsed with warm water at 40°C, after which 1.0 g of each cleanser composition was evenly applied to the hair and the hair strands were gently rubbed together for approximately 30 seconds to create a lather. Subsequently, while rinsing with warm water at 40°C, the smoothness of the hair upon rinsing was evaluated by three expert panelists using the following five-point scale (the evaluation criteria were: Example 10 was assigned a score of "5", Comparative Example 3 was assigned a score of "1", and the intermediate score was assigned a score of "3"). The evaluation values ​​shown in Tables 1 to 6 are the average values ​​of three expert panels. [Evaluation criteria] 5: Less creaking and smooth feel 4: Slightly less creaking 3: Neither 2: Slightly creaky 1: It feels squeaky and not smooth.
