Description

  The present invention relates to an oily cosmetic for hair, which is substantially free of water.

  Conventionally, hair wax, hair cream and the like in which oil and water are emulsified have been widely used as cosmetics for applying hair to hair after stretching it sufficiently on the fingers or palms. However, many of these emulsions have a problem that they cannot be set as desired during hair styling because they are highly formulated with water.

  On the other hand, there is a non-aqueous wax that does not contain water consisting of solid oil and non-volatile oil, so-called cosmetics called clay. Such non-aqueous waxes have the advantage that they can be set as desired when styling hair, but when blended with a high amount of solid oil, the problem is that stretching on fingers and palms, and washing off from the hair after styling worsens. There is. In addition, when non-volatile oil is highly blended, stickiness peculiar to oil is likely to occur, hair styling retention power is poor, and it is necessary to recreate the hairstyle many times. In addition, there is a problem that separation occurs in a high temperature range and the storage stability of the preparation is deteriorated.

  In order to solve such problems, attempts have been made to reduce stickiness and impart hair-styling retention force. For example, a hair wax product containing a silicone-free wax, a liquid hydrophobic oil and a silicone wax and not containing water has been proposed (see, for example, Patent Document 1). However, although such an attempt can improve the stickiness peculiar to oil or to improve the hair holding power, there is a problem that it is inferior in re-styling. In addition, separation is likely to occur at high temperatures, and the storage stability of the preparation is not yet satisfactory.

  Attempts have also been made to reduce stickiness and impart hair-styling retention and re-styling properties. For example, a spray hair wax that contains a film-forming resin, a liquid ester oil, and a semi-solid oil and does not contain water has been proposed (see, for example, Patent Document 2). However, although it is possible to improve the stickiness peculiar to oil, or to improve hair retention and re-styling properties by such an attempt, it is difficult to set as desired during hair styling because it is a spray type. It has the problem that it is inferior to washing off from hair. In addition, the storage stability of the preparation is not satisfactory.

(Test Example 4: Re-styling evaluation)
After the evaluation of Test Example 3, the evaluation panel 20 persons combed the hair of the wig with a comb 10 times, and again, the hair styling was performed in the same manner as in the evaluation of the operability at the time of hair styling in Test Example 2. Sensory evaluation was performed according to the operability evaluation criteria.

(Test Example 5: Evaluation of washing off from hair)
The hair of the wig prepared in Test Example 4 was shampooed with lukewarm water using a shampoo (trade name LUCIDO Shampoo, manufactured by Mandom Co., Ltd.) and subjected to sensory evaluation according to the following evaluation criteria by 20 evaluation panels.

<Evaluation criteria for wash-off from hair>
◎: More than 16 out of 20 people answered that it was not sticky and washed out well ○: 11-15 out of 20 people answered that it wasn't sticky and washed off △: 6-10 out of 20 people were not sticky and washed off Answer that it is good ×: 5 or less of 20 people answered that it was not sticky and washed off well
