Description

The present invention relates to a hair wax . In addition, the room temperature in this invention represents the temperature range of 1-30 degreeC.

  Conventionally, solid oils such as waxes have been used to provide hair-styling properties such as “start up”, “scatter”, “combine”, and “arrange” which are characteristic functions of emulsified cosmetics for hair styling such as hair wax. It has been. In order to obtain such hair styling characteristics, among waxes, high melting point waxes such as carnauba wax and candelilla wax having a high melting point and a hard property are widely used.

  Specifically, for example, a hair-styling composition containing waxes having a melting point of 60 ° C. or higher, a water-in-oil acrylic polymer emulsion, and water (see, for example, Patent Document 1), wax, and high-polymerization polyethylene A cosmetic for hair containing glycol and a nonionic surfactant (for example, see Patent Document 2) has been reported. Further, a hairdressing composition containing vinyl caprolactam homopolymer, 25 ° C. solid oily component, 25 ° C. liquid oily component and water (see, for example, Patent Document 3), waxes, specific liquid oil, volatile liquid Hair styling containing oil and water (for example, see Patent Document 4), hair styling containing 20 ° C. solid wax and volatile silicone (for example, see Patent Document 5) and the like have been reported.

  However, among these high-melting waxes, carnauba wax is extremely difficult to emulsify due to its properties and composition. If low-melting hydrocarbons such as petrolatum, lanolin and beeswax and waxes are not used in combination, Further, there is a problem that the emulsification stability cannot be ensured and its use is restricted. In addition, when low melting point hydrocarbons and waxes are used in combination, there is a problem that excellent hair styling properties are difficult to be exhibited.

  In addition, when Carnauba wax is added at a high level in order to impart excellent hair styling properties, emulsification becomes difficult, and aggregation and precipitation occur over time, resulting in adverse effects on emulsification stability. Furthermore, since the viscosity of the preparation itself becomes high, it becomes hard, and there is a problem that it is difficult to apply at the time of application, poor spreadability on hair, poor operability, and sticky feeling.

(Test Example 2: Evaluation of hair styling properties (power to raise hair, ability to group hair))
The evaluation panel 20 people used the hair wax obtained in each example and each comparative example using a wig (Lesson Mannequin: made by Eucalyptus Japan Co., Ltd.). Evaluation was made from both viewpoints of “strengthening hair” and sensory evaluation was performed according to the following evaluation criteria.

  The evaluation of “power to raise hair” was performed by assuming that the “power to raise hair” was good when the hair was raised from the root and the shape was maintained. In addition, the evaluation of “power to bundle hair” was performed on the condition that the shape of the hair that was held up was bundled and the hair was held was considered good.
