Description

  The present invention relates to an emulsified composition for hairdressing agents.

  Conventionally, oil preparations such as waxes and hydrocarbons are mainly used for hair styling agents composed of emulsified compositions such as hair waxes and hair creams in order to impart excellent hair styling, which is the main function of the hair styling agent. Contains a large amount. The hair styling characteristic of these oil agents is that re-hair styling such as hair styling once can be easily performed.

  However, when an effective amount of these oils is blended in order to ensure the main function, re-hairing can be easily performed, but there is a problem that the oily is conspicuous and stickiness is inferior. There is also a problem that glare peculiar to oil agents stands out and it is difficult to obtain a light finish with a natural texture.

  In order to solve such problems, attempts have been made to reduce the stickiness and glare peculiar to oil agents by incorporating powder into the emulsion composition. For example, an emulsified hair cosmetic containing a specific amount of liquid oil, a higher alcohol or higher fatty acid, a water-insoluble powder for cosmetics, a surfactant, and water in specific amounts (for example, Patent Document 1) Reference), an insoluble silicone powder or organic powder, a silicone oil having a specific viscosity, a thickening polymer compound having a carboxy group or a salt thereof, and a surfactant, and an oil-in-water emulsion hair styling composition A thing (for example, refer patent document 2) etc. is proposed.

  However, although these attempts can reduce the feeling of stickiness and glare to some extent, there is a problem that it is inferior in the excellent re-hairing property that is the main function of the oil agent. In addition, as a means of reducing stickiness and glare, it is conceivable to reduce the blending amount of the oil agent itself, but this method has a problem that the main function as a hair styling agent cannot be fully exerted, is not.

(Sample preparation 1)
According to the composition described in Tables 1 to 3, each hair styling emulsion composition of Examples 1 to 10 and Comparative Examples 1 to 5 was prepared and subjected to the following evaluation. The results are shown in Tables 1-3. In addition, all evaluation was implemented on the constant conditions of constant temperature and humidity of 23 degreeC and 60% of humidity.

(Test Example 1: Evaluation of hair styling)
Using a wig (Lesson Mannequin: manufactured by Eucalyptus Japan Co., Ltd.), each sample obtained in Examples and Comparative Examples was rubbed against the hair, and the hair was “sticky” according to the following evaluation criteria. Sensory evaluation was performed.

<Evaluation criteria for stickiness>
○: Hair can be styled without stickiness △: Hair can be styled but slightly sticky feeling ×: Hair can be styled, but cannot be sticky or hair style itself

(Test Example 2: Evaluation of texture)
Ten minutes after Test Example 1, 20 hair-styling hairs were seen by 20 sensory evaluation panels, and the “glare” of the hair was visually evaluated according to the following evaluation criteria. Furthermore, this panel actually touched this time, and the “finish feeling” of the hair was subjected to sensory evaluation according to the following evaluation criteria.

<Evaluation criteria with glare>
○: 16 or more of 20 respondents indicated that there was no unnatural glare peculiar to oil agents. △: 10 to 15 people answered that there was no unnatural glare peculiar to oil agents. Nine or less responded that there was no unnatural glare peculiar to oil.

<Evaluation criteria for finished feeling>
○: More than 16 out of 20 people answered that there was no powder floating or dryness, and that there was a light finish with a natural texture. Δ: 10 to 15 out of 20 people were free of powder floating or dryness, and natural Answer: If there is a light finish with a gentle texture ×: 9 or less of 20 respondents say that there is no powder floating or dryness and that there is a light finish with a natural texture

(Test Example 3: Evaluation during re-styling)
After 2 hours from the evaluation in Test Example 2, hair was again rubbed so that the hair was rubbed together, and “re-hair styling” was subjected to sensory evaluation according to the following evaluation criteria.

<Evaluation criteria for re-hairdressing>
