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 them, wax-like emulsified hair styling compositions (so-called hair wax) are characterized by their ease of styling hair and excellent restyling properties (the ability to style hair again after styling 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, the following Patent Document 2 discloses a hair styling product that contains (A) a wax that is solid at 20°C and (B) an isoparaffinic hydrocarbon having a boiling point in the range of 100 to 260°C and / or a volatile silicone having a silicon number of 2 to 8, in which the mass ratio of component (A) to component (B) is 1:3 to 3:1.

[0005] [Patent Document 1] JP 2013-040107 A [Patent Document 2] JP 2007-015935 A Summary of the Invention [Problem to be solved by the invention]

[0006] One of the hair styling properties required for a hair styling composition is the ability to maintain the style of the hair for a long period of time (hair styling 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 hard, thereby enhancing the hair styling retention.

[0007] Meanwhile, hair styling using a hair styling composition is usually carried out through the steps of 1) spreading the hair styling composition on the palm to a certain extent, 2) applying the hair styling composition to the hair, and 3) styling the hair into a desired hairstyle while spreading the hair styling composition on the hair.

[0008] Conventional emulsified hair styling compositions containing a wax that is solid at 25° C. have poor spreadability on hair during styling and are poor in usability. With conventional emulsified hair styling compositions containing a wax that is solid at 25° C., even if it is possible to improve the spread of the emulsified hair styling composition on the palm and when applied to hair to a certain extent, it is difficult to improve the spread of the emulsified hair styling composition on hair during styling.

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.

[0153] The method for producing the emulsified hair styling composition of the present invention includes, for example, a method of mixing and emulsifying each component. A homomixer or the like is used for mixing and emulsifying. The emulsification may be a phase inversion emulsification. The emulsification may be performed after mixing each of the above components, or may be performed when mixing each of the components.

[0154] 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 assumption and is not limited thereto.

[0155] The emulsified hair styling composition containing component (A) exerts the hair bundle stiffening, hair styling power to form hair bundles, and hair styling retention power by the breakdown of oil droplets in oil-in-water (O / W) and the attachment of component (A) to hair. However, when the oil droplets break down and component (A) attaches to hair, the hair becomes more squeaky and the hair styling composition spreads poorly. In the conventional emulsified hair styling composition containing component (A), the time until the oil droplets break down is short, and the spread of the hair styling composition decreases while the hair is being arranged after the hair styling composition is applied to the hair (i.e., the spread of the hair styling composition on the hair during hair styling is poor), so there is not enough time to arrange the hair. For example, in the conventional emulsified hair styling composition containing component (A), even if the spread of the hair styling composition can be improved to some extent when applied, it is difficult to improve the spread of the hair styling composition on the hair during hair styling. For this reason, in the case of a conventional emulsified hair styling composition containing component (A), it is necessary to arrange the hair into a desired hairstyle in a relatively short time after applying the hair styling composition to the hair. If the content of component (A) is reduced in order to improve the spread of the hair styling composition on the hair during styling to a certain extent, the styling retention decreases.

[0156] In contrast, the emulsified hair styling composition of the present invention uses component (B) containing component (B1) in addition to the essential components (A), (C), and (D) of the emulsified hair styling composition. In the present invention, it is considered that the stability of the oil droplets themselves is further improved by the inclusion of component (B1) in the oil droplets. Therefore, by using component (B1), the time until the oil droplets break down is extended, and the hair styling composition can be spread more smoothly on the hair during styling.

[0157] The emulsified hair styling composition of the present invention can ensure good spread of the hair styling composition on hair during styling, even when a relatively large amount of component (A) is contained. In the present invention, specific components (A) to (D) and component (B1) are used in combination, and therefore it is possible to achieve the effect of ensuring good spread on hair during styling, which was difficult to achieve with conventional emulsified hair styling compositions containing component (A).

[0169] Component (C) that does not correspond to any of components (C1) to (C3): Stearic acid Sodium dioleth-8 phosphate

[0170] (Component (H)) Polyglyceryl-10 Decaisostearate

[0171] (Component (D)) purified water

[0172] (Component (E)) Stearyl alcohol Behenyl Alcohol

[0173] (Component (F)) Carboxyvinyl Polymer Xanthan gum

[0175] (others) Triethanolamine (neutralizer) 1,3-Butylene glycol (polyhydric alcohol) Diatomaceous earth (powder) Silica (powder)

[0176] (Examples 1 to 25 and Comparative Examples 1 and 2) The components shown in the following Tables 1 to 10 were blended (unit: mass%), and mixed and emulsified using a homomixer to prepare emulsified hair styling compositions. The blend amounts in the tables (amount blended in 100% by mass of the hair styling composition) are shown as the blend amounts of pure components (unit: mass%).

[0177] In the examples and comparative examples other than Examples 7 and 11, triethanolamine is blended at a content of 1.0 mass% or less, which is a content that neutralizes the carboxyvinyl polymer. In Example 11, triethanolamine is blended at a content of 2.0 mass% or less, which is a content that neutralizes the carboxyvinyl polymer and stearic acid.

[0178] The emulsified hair styling composition obtained in Examples 1 to 25 all had a wax-like appearance.

[0179] (evaluation) A three-member expert panel conducted the following evaluations:

[0180] (Test Example 1: Spread on hair during styling) 1.5 g of the obtained emulsified hair styling composition was placed in the palm of the hand, spread on the palm, and then evenly applied to the hair of a short-haired hair wig (Lesson Mannequin, manufactured by Eucalyptus Japan Co., Ltd.), and the hair was lifted upwards from the roots to style the hair.

[0181] The ease of use during hair styling from the start to the end of hair styling (approximately 3 minutes) (i.e., whether or not the hair can be operated during hair styling) was evaluated according to the following evaluation criteria. The emulsified hair styling compositions obtained in Examples 1 to 25 were good in terms of spreadability on the palm of the hair styling composition and spreadability (applicability) when applied to hair.

[0182] <Evaluation criteria for spread on hair during styling> 〇〇 (Good): Until the end of styling, there is no resistance that makes your fingers feel like they are getting caught, and you can style your hair with ease. ○ (Usable): During the latter half of styling, there is a sense of resistance as if the fingers are getting caught, but during styling, operability that is practically acceptable is maintained. × (bad): Before the hair styling is completed, there is a strong sense of resistance, as if fingers are caught, making hair styling difficult.

[0183] (Test Example 2: Hair styling retention) The hair wig that had been styled in Test Example 1 was left to stand for 6 hours. After being left to stand, the hair wig was shaken back and forth for 1 minute. The angle at which the hair rose near the top of the hair wig after shaking was visually observed, and the styling retention was evaluated according to the following evaluation criteria. The above angles were defined as 0° in the horizontal direction and 90° in the vertical direction. In Examples 1 to 25 and Comparative Examples 1 and 2, the hair near the top of the head rose to approximately 90° immediately after styling.

[0184] <Evaluation criteria for hair styling hold> ○ (Good): The angle of the hair near the top of the head is maintained at 45° or more. × (Poor): The angle of the hair near the top of the head is less than 45° and the hair is drooping.

[0185] (Test Example 3: Washability) The hair wig after evaluating the hair styling retention in Test Example 2 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 further dried with a hair dryer. When the dried hair was touched with a hand, the hair that had been styled with the emulsified hair styling composition obtained in Examples 1 to 10 and 12 to 25 did not feel like the hair styling composition remained on the hair after washing and drying. On the other hand, the hair that had been styled with the emulsified hair styling composition obtained in Example 11 felt stiff after washing and drying, and felt like the hair styling composition remained on the hair.

[0186] (Test Example 4: Emulsifying properties) The resulting emulsified hair styling composition was dropped and spread on a glass plate immediately after production, and visually observed. As a result, in the emulsified hair styling composition obtained in Examples 1 to 25, no granular insoluble matter was observed, the composition had a uniform property, and was well emulsified.
