Description

  The present invention relates to an emulsified cosmetic for hairdressing. In addition, the room temperature in this invention represents the temperature range of 1-30 degreeC.

  The emulsification is one in which one of two layers that are not mixed with each other, such as water and oil, is used as a dispersed phase and dispersed in a stable state in the other dispersion medium. Typical emulsification includes oil-in-water (O / W type) emulsification and water-in-oil (W / O type) emulsification.

  Oil-in-water (O / W) emulsions as hairdressing cosmetics have a refreshing feeling with less oiliness and are easily washed off with water. It has the disadvantage of being inferior. In addition, when the solid oil content is high, there are disadvantages such as conformity to the hair, loss of stretchability, and deterioration in emulsion stability due to curing (solidification) of the preparation. On the other hand, the water-in-oil type (W / O type) emulsion has a high oil content, so it has the characteristics of being familiar with the hair, extensibility, and texture, while being easy to operate at the time of styling. In addition, it has the disadvantages of giving a sticky feeling, poor washing off with water, and poor emulsion stability.

  In order to solve these disadvantages, waxy and hydrocarbon oils are dispersed in water to make an oil-in-water hair cosmetic, thereby suppressing stickiness, hair styling, and smoothness to hair. Attempts have been made (see, for example, Patent Document 1). Further, by making a water-in-oil hair cosmetic containing a cross-linked polyether-modified silicone and a specific copolymer and having an aqueous phase of 50% by weight or more, the feeling of stickiness is suppressed, and the hair styling power, hair Attempts have been made to impart smoothness to the emulsion and to improve the emulsion stability (see, for example, Patent Document 2).

  However, even with these attempts, hair styling cosmetics having characteristics of both an oil-in-water emulsion and a water-in-oil emulsion have not been obtained. Therefore, it is desired to develop a hair styling cosmetic that eliminates the drawbacks of both emulsions and combines the characteristics of both emulsions.
