Description

  The present invention relates to a wax-like emulsified hair styling agent. The “wax-like” of the wax-like emulsified hair styling agent in the present invention refers to a dosage form solidified at room temperature, and is a composition filled when a wide-mouthed container is filled and the container is tilted at 90 ° for 1 minute. Refers to those that do not exhibit fluidity. In addition, room temperature represents the temperature range of 1-30 degreeC.

  Hair styling products are largely classified into oily hair styling agents and aqueous hair styling agents depending on the types of ingredients to be blended and the types of dosage forms formed. The oil-based hairdressing agent is a hairstyling agent in which a large amount of oily components typified by vegetable oil and mineral oil are blended without blending moisture, and examples thereof include hair oil, pomade, and ticks. Oil-based hair styling is formulated with a large amount of oil-based ingredients, so it has an excellent effect on hair-styling power, but it has drawbacks peculiar to oil-based ingredients such as hair stickiness, oiliness, and unnatural luster. It was.

  On the other hand, the oily component is reduced or reduced in the aqueous hairdressing material, and it is possible to suppress the stickiness, oiliness, and unnatural glossiness of the hair. However, there is a problem that the hair styling power is inferior to that of oil-based hair styling materials. Therefore, attempts have been made to add hair-styling power by blending various polymer compounds such as gum and film-forming resin into an aqueous hair-styling material. However, although the holding power of the set is improved by the blending of the polymer compound, there is a problem that the polymer compound has disadvantages peculiar to the polymer compound such as wrinkle and squeak, and the hair styling property is poor.

  On the other hand, in recent years, there is a tendency that not only conventional hair styling such as straightening hair but also hair styling such as making unintentional movements or creating a three-dimensional feeling. In order to perform such hair styling, a hair styling material having both high set holding power and re-styling properties is desired. Therefore, emulsified hair conditioners such as hair waxes and hair creams that contain a large amount of oil components such as waxes, waxes, esters, and hydrocarbons have been proposed (see, for example, Patent Documents 1 to 3). .

  However, an emulsified hair styling compounded with a large amount of these oil-based raw materials can impart high set retention and re-styling properties to the hair, but is inferior in stretchability on the hair, causing stickiness, It had the disadvantage of being inferior to washing off.
