Description

[Technical Field]

[0001] The present invention relates to an emulsified hair styling composition that is suitable for use as a hair styling agent for styling hair. [Background technology]

[0002] Hair styling compositions are known in various forms, such as liquid, gel, cream, wax, etc. Among these, waxy emulsified hair styling compositions (so-called hair waxes) are characterized by their ease of styling hair and excellent restyling properties (the ability to style hair again after styling it once).

[0003] For example, Patent Document 1 listed below discloses an emulsion-type hair styling product containing (A) candelilla wax, (B) a volatile hydrocarbon, (C) an ester of a linear fatty acid having 12 to 22 carbon atoms, (D) a linear methylpolysiloxane having a specific structure, and (E) a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer.

[0004] Furthermore, Patent Document 2 listed below discloses a hair styling product containing (A) a wax that is solid at 20°C and (B) an isoparaffinic hydrocarbon and / or a volatile silicone having a silicon number of 2 to 8, the mass ratio of component (A) to component (B) being 1:3 to 3:1.

[0006] One of the hair styling properties required for a hair styling composition is the ability to maintain the style for a long period of time (hair style retention). In an emulsified hair styling composition such as hair wax, for example, by blending a wax that is solid at 25°C, the hair bundle after styling can be made stiff, thereby enhancing the hair style retention.

[0007] Conventional emulsified hair styling compositions containing wax that is solid at 25°C may have poor emulsifying properties, and the oily and aqueous components may not be sufficiently emulsified. Furthermore, depending on the type of emulsifier, the wash-off properties of the emulsified hair styling composition may be reduced.

[0008] An object of the present invention is to provide an emulsified hair styling composition that can enhance emulsification properties and can improve wash-off properties during hair washing. [Means for solving the problem]

[0142] (Other details of the emulsified hair styling composition) The emulsified hair styling composition of the present invention is an emulsion composition in which an oily component and an aqueous component are emulsified. The emulsified hair styling composition of the present invention is preferably an oil-in-water (O / W) type emulsified hair styling composition.

[0143] The emulsified hair styling composition of the present invention is preferably in the form of a wax. The emulsified hair styling composition of the present invention is preferably a wax-like emulsified hair styling composition (so-called hair wax). The wax-like composition also includes a balm-like composition.

[0144] Examples of methods for producing the emulsified hair styling composition of the present invention include a method in which the components are mixed and emulsified. A homomixer or the like is used for the mixing and emulsification. The emulsification may be phase inversion emulsification.

[0145] The relationship between the configuration of the present invention and the effects of the present invention will be described in more detail below. However, the relationship between the configuration of the present invention and the effects of the present invention described below is an estimate and is not limited thereto.

[0146]

[0003] In an emulsified hair styling composition containing component (A), oil droplets in the oil-in-water (O / W) disintegrate, allowing component (A) to adhere to hair, thereby stiffening hair bundles and providing styling power for taming hair, styling power for forming hair bundles, and hair styling retention. However, component (A) is difficult to emulsify, and particulate insoluble matter is generated in the emulsified hair styling composition, the emulsified hair styling composition becomes non-uniform, and the emulsification properties are easily reduced. In conventional emulsified hair styling compositions containing component (A), higher fatty acid salts, which are excellent at emulsifying component (A), have generally been used as emulsifiers. However, when higher fatty acid salts are used as emulsifiers, there have been problems such as the emulsified hair styling composition's ease of rinsing off during hair washing and its alkaline nature, which reduces the stability of the ingredients.

[0147] In contrast, the emulsified hair styling composition of the present invention uses component (C1) and / or component (C2) as an essential emulsifier component, thereby improving the emulsifying properties of component (A) without causing problems such as reduced washability during hair washing. Components (C1) and (C2) have long-chain linear alkyl groups. The linear alkyl groups in components (C1) and (C2) presumably have a high affinity with component (A), making it easier to emulsify component (A). Furthermore, because components (C1) and (C2) are ionic surfactants, electrostatic repulsion of the emulsified particles increases the dispersibility of the emulsified particles, further improving the emulsifying properties.

[0168] The emulsified hair styling compositions obtained in Examples 1 to 28 were all wax-like in nature.

[0169] (evaluation) A three-person expert panel conducted the following evaluations:

[0170] (Test Example 1: Emulsifying properties) The resulting emulsified hair styling composition was dropped onto a glass plate immediately after production, spread, and visually observed. The emulsification properties were evaluated according to the following evaluation criteria. Note that in Comparative Example 3, the emulsification properties were poor, so the evaluations of the following Test Examples 2 to 4 were not performed.

[0171] <Evaluation criteria for emulsifying properties> ◯ (Good): No granular insoluble matter, uniform properties. × (bad): Granular insoluble matter is observed or the product is non-uniform in appearance.

[0172] (Test Example 2: Hair styling retention) 1.5 g of the resulting emulsified hair styling composition was dispensed into the palm of the hand, spread over the palm, and then evenly applied to the hair of a short-haired hair wig (a lesson mannequin, manufactured by Eucalyptus Japan Co., Ltd.). The hair was then styled by lifting it upward from the roots. The styled hair wig was left to stand for 6 hours. After standing, the hair wig was shaken back and forth for 1 minute. After shaking, the angle at which the hair rose near the crown of the wig was visually observed, and the styling retention was evaluated according to the following evaluation criteria. The horizontal angle was defined as 0°, and the vertical angle was defined as 90°. In Examples 1 to 27 and Comparative Examples 1 and 2, the hair near the crown rose to approximately 90° immediately after styling.

[0173] <Evaluation criteria for hair styling hold> ○ (Good): The angle of hair near the top of the head is maintained at 45° or more. × (bad): The hair near the top of the head is hanging down at an angle of less than 45°.

[0174] (Test Example 3: Washability) After evaluating the hair styling hold power in Test Example 2, the hair wig was washed with a commercially available shampoo and then rinsed with running water (warm water of about 40°C). The hair was towel-dried and then dried with a hair dryer. The dried hair was touched with hands, and the washability was evaluated according to the following evaluation criteria.

[0175] <Evaluation criteria for washability> ◯ (Good): Hair is not stiff after washing and drying, and there is no feeling of any hair styling composition remaining. × (bad): Hair feels stiff after washing and drying, and there is a feeling that the hair styling composition remains.

[0176] (Test Example 4: Spread on hair during styling) When styling hair in Test Example 2, the spread on the hair during styling was evaluated based on ease of use (i.e., whether or not it could be operated during styling) from the start to the end of styling (approximately 3 minutes).

[0177] As a result, the emulsified hair styling compositions obtained in Examples 1, 2, 6, 8 to 12, 13, 16 to 19, 21 to 27 and Comparative Examples 1 and 2 did not cause any resistance, such as fingers getting caught, until the end of styling, allowing for easy manipulation and good spread. Among them, the emulsified hair styling compositions obtained in Examples 19, 21 to 24 showed extremely excellent spreadability on the hair during styling. Furthermore, the emulsified hair styling compositions obtained in Examples 3 to 5, 7, 14, 15, and 20 caused some resistance, such as fingers getting caught, in the latter half of styling, but maintained practically acceptable operability and spreadability during styling. On the other hand, the emulsified hair styling composition obtained in Example 28 caused a strong resistance, such as fingers getting caught, before the end of styling, making styling difficult (though this composition is not suitable for long-term styling, it can be used for short-term styling).
