Description

  The present invention relates to hair cosmetics, and more specifically, it has no conditioning and stickiness at the time of application, and is excellent in conditioning properties such as giving a smooth and moist feel to the hair with smooth fingers and combs. The present invention relates to a hair cosmetic that has an appropriate hair holding ability, has no dryness after drying, suppresses the spread of hair, and maintains unity.

  There are various dosage forms such as waxes, gels, creams, foams, sprays, lotions and the like as hair cosmetics for shaping the hair style. These hair cosmetics are generally blended by dissolving or emulsifying polymer compounds, oils, waxes and the like in order to set the hair. Conventionally, most liquid hair cosmetics use a high molecular weight compound to produce hair-styling retention. However, in order to increase the hair holding power, increasing the blending amount of the polymer compound makes it possible to achieve both the hair holding power and the touch surface during use due to the appearance of stickiness and stickiness, or the appearance of flaking. It was difficult.

In response to such problems, silicone emulsions and the like are added to improve the feel of the hair, improve fingers and combs, or protect the hair (for example, Reference 1), amino acids, sugars, polyphenols, plants There are some ingredients (such as References 2 and 3) that try to impart smoothness to hair by blending extracted ingredients, organic acid and other hair protecting ingredients, but stickiness during application, dryness after drying, etc. Therefore, good usability could not be obtained. In addition, these components often act as plasticizers for polymer compounds, and it has been difficult to achieve both hair holding ability and usability.
