[Problems to be solved by the invention]
Conventional hair waxes are excellent in hair styling, but have a problem that they cause stickiness and stiffness when applied to hair, and lack gloss and smoothness. Various attempts have been made to solve such a problem, as described in Patent Documents 1 and 2 above, but none of them have yielded satisfactory results. Further, for example, when a high molecular silicone, a humectant, or the like is added to wax for the purpose of improving tackiness or stiffness, separation was easy due to poor compatibility, and a sufficient effect was not obtained.
[0010]
By using creams and gels that provide luster and smoothness together with wax, you can improve the stickiness and stiffness of the wax while maintaining the hair styling power of the wax, but you can separate the wax and cream or gel from separate containers However, it is troublesome to use them, and furthermore, there is a large variation in the use ratio between the two, and it has been difficult to always obtain a constant use effect. In addition, when a wax component and a cream or gel component are mixed together to form a formulation, there is a problem that stability is poor and separation is easy, and further, usability is poor.
[0011]
Therefore, hair cosmetics filled in one container in a state in which wax having hair styling properties and cream or gel that brings gloss and smoothness are uniformly distributed without being mixed with each other, that is, in a mixed state. Was desired. A combination of an O / W type wax and an O / W type cream or an aqueous gel is preferable because it is easy to wash the hair and to wash off when attached to hands. In such a combination, an O / W type and a W type are preferred. It is more unstable than the combination with the / O type, or the combination of the W / O type and the W / O type, and the O / W type wax and the O / W type cream or The aqueous gel could not be filled in one container so that it could be stably maintained in a mixed state.
[0012]
The present invention has been made in view of the above circumstances, and has excellent stability and usability. In a state where O / W type wax and O / W type cream or water-based gel are mixed, one container is stably provided. It is an object of the present invention to provide a hair cosmetic filled with a hair cosmetic.
[0013]
[Means for Solving the Problems]
In the hair cosmetic of the present invention, a first portion composed of an O / W type wax and a second portion composed of an O / W type cream or an aqueous gel are filled in one container in a mixed state, The hardness of the two parts is 2 to 10 g, and the difference in hardness between the two parts is 3 g or less. In particular, it is preferable that the hardness of the first portion is 0.5 to 1 g higher than the hardness of the second portion.
[0014]
Here, the “container” includes any container usually used for hair cosmetics, unless otherwise limited, and includes, for example, a transparent or translucent glass or plastic container, or a tube.
[0015]
Further, the “mixed state” means a state in which one is uniformly distributed with respect to the other without being mixed with the whole. For example, a state where both portions are filled in a spiral shape, a lattice shape, or a stripe shape may be mentioned. With such a configuration, the hair cosmetic can be used so that both parts are always contained at a fixed ratio regardless of the location.
[0016]
The term “hardness” as used herein means a value measured at room temperature (25 ° C.) using a card meter (manufactured by Eye Techno Engineering Co., Ltd., pressure-sensitive shaft 11.3 mmφ / 200 g load value). If at least one part has a hardness of less than 2 g, both parts are easily mixed with each other, and if at least one part has a hardness of more than 10 g, it becomes difficult to scoop by hand, resulting in poor usability. Also, if the hardness difference between the two parts is larger than 3 g, it is impossible to always take the two parts at a constant rate, and it is difficult to apply the two parts to the hair uniformly by hand or hair. become.
[0017]
Further, it is preferable that the first portion and the second portion are spirally filled in a ratio of 3: 7 to 7: 3. For example, both portions are spirally filled in a ratio of 1: 1. . Further, it is preferable that the first portion is white and the second portion is colored.
[0018]
It is preferable that the second part does not contain a solid oil component, and when the second part is made of an O / W type cream, it is preferable that a high molecular silicone is blended in the cream.
[0019]
As used herein, the term "solid oil content" means any lipophilic substance that is solid at 1 atm and 20 ° C. and can be incorporated into cosmetics.
[0020]
【The invention's effect】
Since the hair cosmetic composition of the present invention is composed of an O / W wax and an O / W cream or an aqueous gel each having a hardness of 2 to 10 g and a difference in hardness of 3 g or less, one Even if the mixture is filled in the container, the wax portion and the cream or gel portion are hardly mixed with each other, and can be stably stored in a mixed state. Furthermore, since the hair cosmetic composition of the present invention can always use both preparations at a fixed ratio, the hair styling effect of wax and the effect of luster and smoothness of cream or gel are balanced, sticky and stiff. It can provide excellent finish without any.
[0021]
Furthermore, when the wax is white and the cream or gel is colored, the appearance is excellent, and even if the two preparations are slightly mixed, it is hard to recognize visually, and Beauty can be maintained.

In particular, hair cosmetics filled with O / W type wax and O / W type cream at a ratio of 50 parts to 50 parts, that is, 1: 1 gave the most excellent finish.
[0049]
Examination of filling ratio of O / W type wax and aqueous gel
The O / W wax and the aqueous gel prepared according to Example 2 were simultaneously and continuously supplied at various rates from two adjacent nozzles to a cylindrical container rotating around a central axis, / W wax and a water-based gel were spirally filled at various ratios to prepare hair cosmetics. Based on the above-described evaluation methods and evaluation criteria, the hair cosmetics filled in each ratio were evaluated for finish (hair styling, non-stickiness, gloss) and storage stability. The results are shown in Table 3:
[Table 3]

A hair cosmetic filled with an O / W type wax and an aqueous gel in a ratio of 50 parts to 50 parts, 70 parts to 30 parts, or 30 parts to 70 parts has sufficient hair-styling power and is non-sticky. Brings a glossy finish. In particular, the hair cosmetics filled with the O / W type wax and the aqueous gel at a ratio of 50 parts to 50 parts, that is, 1: 1 gave the most excellent finish.
[0050]
Examination of hardness of O / W type wax and O / W type cream or aqueous gel
O / W type waxes and O / W type creams or aqueous gels having various hardnesses were prepared in the same manner as in Examples 1 and 2 by adjusting the amount of the carboxyvinyl polymer as a thickener. The hardness was measured based on the method described above. O / W waxes having various hardnesses and O / W type creams or aqueous gels were spirally filled into containers in the same manner as in Examples 1 and 2. For hair cosmetics composed of O / W wax having each hardness and O / W type cream or aqueous gel, usability and drop stability were evaluated based on the following evaluation methods and evaluation criteria.
[0051]
Usability evaluation method and evaluation criteria
The usability of the hair cosmetics was evaluated based on the following evaluation methods and evaluation criteria. Two items were evaluated: ease of scooping by hand and familiarity of both parts.
[0052]
After the use of each hair cosmetic, 10 panelists scored the ease of hand picking and the ease of fitting both parts according to the following criteria:
Good: 2 points
Normal: 1 point
Bad: 0 points
Regarding the total points, 11 points or more: A, 5 to 10 points: B, and less than 5 points: C.
[0053]
Evaluation method and evaluation criteria for drop stability
The drop stability was evaluated as follows by observing a change in appearance when the hair cosmetic was dropped on concrete from a height of 50 cm.
A: No change
B: The pattern changes but the boundaries are sharp
C: The border becomes unclear
The results are shown in Tables 4 and 5:
[Table 4]

[Table 5]

Hair cosmetics in which the hardness of both parts is in the range of 2 to 10 g and the hardness difference between the two parts is 3 g or less have good drop stability, and are easy to handle both parts at a constant rate. In addition, both parts were easy to adjust and excellent in usability. In particular, when the hardness of the wax portion was 0.5 to 1 g higher than the hardness of the cream or gel portion, the stability was very good and the usability was excellent. If at least one part has a hardness of less than 2 g, the drop stability is poor and it is easy to mix with each other. I was Further, when the hardness difference between the two parts was more than 3 g, it was difficult to always hold the two parts at a constant rate, and it was difficult to blend the two parts with hands and hair, resulting in poor usability.
