BACKGROUND OF THE INVENTION
The present invention relates to a hair cream, and more particularly to a hair cream that has little hair stickiness when used on hair, has good hair cohesiveness, and has good hair slipperiness when finished.
[0002]
[Prior art]
Conventionally, various hair creams have been proposed. However, since they give the hair a feeling of weight when used, there is a problem that the hair becomes sticky.
[0003]
[Problems to be solved by the invention]
The present invention solves the problems of the conventional hair cream as described above, and provides a hair cream with less stickiness, good hair cohesiveness, and good hair slipperiness when finished. Objective.
[0004]
[Means for Solving the Problems]
As a result of intensive studies to solve the above problems, the present inventors have found that when preparing a hair cream containing soy phospholipid, waxes and silicone oil, the hair is less sticky and the hair It has been found that a hair cream having good cohesiveness and good slipperiness of the hair when finished can be obtained, and the present invention has been completed.
[0005]
That is, the hair cream of the present invention was used for hair because the contained soybean phospholipid has an emulsifying action to form a stable emulsifier, and the soybean phospholipid has a moisturizing effect. Occasionally, the hair does not give a feeling of weight or stickiness, and the waxes are solid at room temperature, so that the hair has good cohesiveness, and the silicone oil has excellent slipperiness. Good slipperiness can be imparted to the hair at the time.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the content of soybean phospholipid in the hair cream (the amount incorporated in the hair cream) is preferably 0.01 to 0.3% by weight, particularly preferably 0.01 to 0.1% by weight. . When the content of soybean phospholipid in the hair cream is less than the above range, the emulsifying action is not sufficient, the hair cream lacks stability as an emulsion, the commercial value may be impaired, and the hair may become sticky In addition, when the content of soybean phospholipid in the hair cream is more than the above range, the hair cream may become too hard and difficult to use.
[0007]
In the present invention, the waxes are not particularly limited. For example, candelilla wax, paraffin wax, microcrystalline wax, ceresin, isopropyl myristate, dioctyl succinate and the like are preferably used.
[0008]
The content of these waxes in the hair cream (the amount incorporated in the hair cream) is preferably 0.5 to 5% by weight, particularly preferably 0.1 to 3% by weight. When the content of waxes in the hair cream is less than the above range, there is a risk that sufficient cohesiveness cannot be imparted to the hair, and the content of waxes in the hair cream is more than the above range In some cases, the hair may feel sticky.
[0009]
In the present invention, the silicone oil is not particularly limited, and examples thereof include dimethylpolysiloxane, amino-modified silicone oil, methylphenylpolysiloxane, polyether-modified silicone oil, gum-like silicone, and alkyl-modified silicone oil. Preferably used.
[0010]
The content of the silicone oil in the hair cream (the amount incorporated in the hair cream) is preferably 1 to 10% by weight, and particularly preferably 3 to 8% by weight. When the content of the silicone oil in the hair cream is less than the above range, there is a possibility that sufficient slipperiness cannot be imparted to the finished hair, and the content of the silicone oil in the hair cream is as described above. When the amount is more than the range, the hair is given a sticky feeling, which may worsen the slipperiness.
[0011]
The hair cream of the present invention is prepared by dissolving, emulsifying or dispersing the above components in water or an aqueous liquid containing water as a main ingredient. In this case, in addition to the above components, if necessary, fatty acids, Surfactants such as alkalis, cationic surfactants, nonionic surfactants, ester oils, higher alcohols, polyhydric alcohols, fragrances and the like can be appropriately contained.
[0012]
【Example】
Next, the present invention will be described more specifically with reference to examples. However, this invention is not limited only to those Examples. In the following examples and the like, some are used in the form of a solution or a dispersed liquid, but the blending amount is shown as a solid content (or pure content).
[0013]
Example 1 and Comparative Examples 1-3
Hair creams of Example 1 and Comparative Examples 1 to 3 were prepared with the compositions shown in Table 1. The unit of the numerical value indicating the blending amount of each component is parts by weight.
[0014]
[Table 1]

[0015]
The hair creams of Example 1 and Comparative Examples 1 to 3 prepared as described above were evaluated for stickiness, hair cohesiveness, and hair slipperiness when finished as shown below.
[0016]
In the evaluation, the test hair bundle was prepared with healthy hair weighing 0.5 g and length 18 cm, one end of which was tied with a rubber band, and the other end (hair tip side) was free (free) ) Was prepared.
[0017]
The hair creams of Example 1 and Comparative Examples 1 to 3 were each applied to this hair bundle after extending by about 0.5 g with the palm of each hand, and the above evaluation items were evaluated by five panelists. The evaluation method and evaluation criteria are as follows.
[0018]
Less sticky:
The hair bundle after applying the hair cream is rubbed twice from top to bottom with three fingers, and the feel at that time is evaluated in four stages according to the following evaluation criteria.
[0019]
Evaluation criteria:
4: I do not mind stickiness.
3: Slightly sticky.
2: Sticky.
1: It is quite sticky.
[0020]
Hair cohesion:
The hair bundle after application of the hair cream is shaken twice, and the subsequent bundle of hair bundles is visually observed (especially focusing on the tip of the hair). And the result is evaluated in four stages according to the following evaluation criteria.
[0021]
Evaluation criteria:
4: Even one hair is gathered without being disturbed.
3: Although several hairs are disordered, the whole hair bundle is gathered.
2: The middle part is gathered, but the hair ends are not gathered.
1: The whole hair bundle is disturbed.
[0022]
Hair slipperiness:
The hair bundle after applying the hair cream is rubbed twice from top to bottom with three fingers, and the feel at that time is evaluated in four stages according to the following evaluation criteria.
[0023]
Evaluation criteria:
4: Good sliding, supple and easy to follow.
3: Good sliding and good fingering.
2: The finger is normal.
1: Bad fingering.
[0024]
The above evaluation results are shown in Table 2 as the average score of five panelists. In addition, in the display in Table 2, the figures after the decimal point are rounded off. As is clear from the above evaluation results, the higher the evaluation value in any evaluation item, the better the characteristics.
[0025]
[Table 2]

[0026]
As shown in Table 2, the hair cream of Example 1 has a high evaluation value in all items, little stickiness, good hair coherence, and good hair slipperiness. Met. On the other hand, Comparative Example 1 containing no soy phospholipid is sticky to the hair, and Comparative Example 2 containing no candelilla wax belonging to waxes has poor hair cohesion and belongs to silicone oil. In Comparative Example 3 in which dimethylpolysiloxane was not blended, the slipperiness of the hair was poor.
[0027]
【The invention's effect】
As described above, according to the present invention, it was possible to provide a hair cream with less stickiness, good hair cohesiveness, and good hair slipperiness when finished.
