Description

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

  Conventionally, so-called hair waxes containing solid oils such as waxes and waxes have been widely used in order to impart hair styling properties and re-styling properties to the hair. As a hair styling method, the hair is generally stretched on the palm and then applied to the hair. However, when a large amount of solid oil is blended, sufficient hair styling properties and re-styling properties can be imparted, but on the other hand, there is a problem that hair does not stretch well on the finger or palm from the container and hair is difficult to stylist. In addition, there is a problem that the stickiness peculiar to oil is likely to occur and the spreadability on the hair is poor. Furthermore, there have been problems such as poor washing from the hands and hair after hair styling and poor temperature stability of the preparation.

  In order to solve such problems, attempts have been made to improve the spreadability on fingers and hair. For example, solid waxes, water-soluble polymers, oils that are liquid at room temperature, hairdressing agents containing powder and water have been proposed (see, for example, Patent Document 1).

  However, although it is possible to improve the stickiness peculiar to fingers and oils by such an attempt, the spreadability on the palm and hair is still not satisfactory. Furthermore, since the powder is contained, there is a problem that hair styling property and re-hair styling property are inferior.

  Attempts have also been made to improve wash-off from hands and hair. For example, hair conditioners containing specific liquid oil, volatile liquid oil, waxes and water have been proposed (see, for example, Patent Document 2).

  However, such attempts have been able to improve washing out from hands and hair, but have problems such as poor hair styling and re-styling. In addition, the spreadability on the palm and hair, and the temperature stability of the preparation are still unsatisfactory.
