Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is a cosmetic containing a polyhydric alcohol ester of rosin and a dialcohol ester of dibasic acid, which has usability, stability and glossiness. Regarding excellent cosmetics.

[Prior Art] Conventionally, polyhydric alcohol ester of rosin has been used as a water resistance improver, a gloss imparting agent, a flexibility imparting agent, an adhesion improving agent for a nail polish forming film, and a hair cosmetic such as a hair spray. It is used as a film-forming agent, an adhesion improver, and as a solidification aid for stick cosmetics such as lipsticks.

However, since the polyhydric alcohol ester of rosin is a solid at room temperature and has a relatively high melting point, it has a drawback that it needs to be dissolved by heating at a high temperature together with other oil agents when compounded in cosmetics. In addition, the compatibility with other oil agents was not so good, there were many restrictions on the formulation constitution, the manufacturing process was troublesome, and there was a defect in the stability of cosmetics.
Furthermore, there are drawbacks in that the tackiness, which is a characteristic thereof, becomes tacky (sticky) and the extensibility is poor.

Therefore, it has been proposed to incorporate a liquid composition obtained by heating and mixing a polyhydric alcohol ester of rosin with a specific ester compound into a cosmetic (Japanese Patent Laid-Open No. 58-16266).
No. 1).

[Problems to be Solved by the Invention] However, although the cosmetics disclosed in JP-A-58-162661 show an improvement as compared with those before, the compatibility is still insufficient, particularly at low temperatures. Also, the stability at room temperature is poor. In addition, the conventional drawbacks of usability such as sticky feeling (stickiness) and poor extensibility have not been solved.

[Means for Solving Problems] In view of the above points, the present inventors have earnestly studied in order to obtain a cosmetic having no defects in usability and stability. As a result, the polyhydric alcohol ester of rosin has a dibasic acid It was found that a cosmetic in which the above-mentioned drawbacks are eliminated can be obtained by using a dialcohol ester together, and the present invention has been completed.

 Hereinafter, the configuration of the present invention will be described.

The polyhydric alcohol ester of rosin used in the present invention is obtained by esterifying a resin acid which is a main component of rosin, hydrogenated rosin and polymerized rosin with polyhydric alcohols.
Examples of polyhydric alcohols constituting the polyhydric alcohol ester of rosin include ethylene glycol, propylene glycol, diethylene glycol, neopentyl glycol, glycerin, trimethylolpropane, hexanetriol, pentaerythrit, dipentaerythritol, and the like. be able to.

The dialcohol ester of a dibasic acid used in the present invention is a diester of a dibasic acid having 4 to 10 carbon atoms and an alcohol having 2 to 8 carbon atoms, and a cosmetic that is safe to the human body can be used.

Examples of the dibasic acid as a constituent component include, for example, succinic acid, glutamic acid, adipic acid, pimelic acid, speric acid,
Azelaic acid, sebacic acid, etc. can be mentioned. Further, as the other component alcohol, for example,
Examples thereof include ethyl alcohol, propyl alcohol, isopropyl alcohol, butyl alcohol, amyl alcohol, hexyl alcohol, and octyl alcohol.

Incidentally, the dialcohol ester of dibasic acid is an oily base that dissolves the polyhydric alcohol ester of rosin very well, and its dissolution temperature can be set lower than that of the conventional one, and its dissolution It only takes a short time. Thus, it is possible to prevent the polyhydric alcohol ester of rosin from being deteriorated by heating, and thus improve the stability of the cosmetic. Further, its solubility is particularly high, and a transparent liquid composition can be obtained even at room temperature, and thus a transparent cosmetic composition can be easily obtained.
Further, it is possible to mix an oil agent having a poor compatibility with the polyhydric alcohol ester of rosin, and it is possible to obtain a cosmetic that is stable for a long period of time.

Further, a liquid composition of a polyhydric alcohol ester of rosin dissolved in a dialcohol ester of a dibasic acid has low viscosity and thixotropic properties as compared with a conventional liquid composition, and particularly has extensibility. Is excellent. In addition, it has less sticky feeling (stickiness) and has an excellent usability.

It was examined by the following method that the dialcohol ester of the dibasic acid according to the present invention has a good dissolving action for the polyhydric alcohol ester of rosin, and the results are shown in Table 1 for reference. The solubility of the ester gum was examined using diisopropyl sebacate as the dialcohol ester of dibasic acid. As a control, octyldodecyl myristate was used. The composition was 100 g of ester gum and 100 g of ester oil, and the heating dissolution temperature under stirring, the dissolution time, and the dissolution state after standing overnight at room temperature after dissolution were examined.

As is clear from the results in Table 1, the diisopropyl sebacate according to the present invention dissolves the ester gum at a low temperature for a single hour, and the dissolved state thereof is also very good.

Further, the viscosity values for the dissolved liquid composition are shown in Table 2.
Shown as a reference. The composition is shown in Table 2. 75g of polyhydric alcohol ester of rosin acid and 75g of ester oil were dissolved by heating under stirring, allowed to cool at room temperature, and set in a constant temperature bath at 25 ° C overnight (4 types). And The viscosity value can be measured by
Using a B-type rotational viscometer (Vismetron VG, manufactured by Shibaura System Co., Ltd.), the measurement was carried out under the conditions of No. 2 rotor, 12 rpm, and after 1 minute.

As is clear from the results shown in Table 2, the liquid composition according to the present invention has an extremely low viscosity, can be easily incorporated into cosmetics, and can be applied to a wide range of cosmetics. It was

The results of the tackiness test for the dissolved semi-solid composition are shown in Table 3 for reference. The composition is as shown in Table 3.
35 g of polyhydric alcohol ester of rosin acid and 15 g of ester oil
And dissolve under heating with stirring, and about 3 ml of a film formed by a doctor blade of 8 mil on a glass plate of 10 × 20 cm at 25 ° C.
Samples were left for 30 minutes (4 types). The tackiness was measured using a surface property measuring machine (Haydon-14, manufactured by Shinto Scientific Instruments Co., Ltd.) using a tack test roll,
It was carried out under the conditions of a weight of 50 g, a movement of 8.0 cm / min, and a tack width of 2 cm.

As is clear from the results in Table 3, the semi-solid composition according to the present invention has extremely low tackiness and is advantageous because it does not give a sticky feeling (stickiness) when blended in a cosmetic composition.

Further, since the dialcohol ester of dibasic acid according to the present invention is particularly excellent in solubility, it is possible to mix an oil agent having a poor compatibility with the polyhydric alcohol ester of rosin. Table 4 shows the results of the compatibility test for reference. As shown in Table 4, as shown in Table 4, six kinds of squalane were used, and they were heated and dissolved under stirring,
In addition, the dissolution state after standing overnight at room temperature was examined.
Partial comparisons were also made with and without ester gum dissolved in ester oil in advance.

As is clear from the results in Table 4, since the dialcohol ester of the dibasic acid according to the present invention is particularly excellent in its solubility, it is possible to obtain a stable cosmetic composition for a long period of time, and a wide range of applications as a cosmetic composition. Is possible. It is also suitable for application as a transparent cosmetic.

The amount of the dialcohol ester of dibasic acid according to the present invention is the polyhydric alcohol ester of rosin in the case where a liquid composition prepared by heating and dissolving with a polyhydric alcohol ester of rosin is blended into a cosmetic composition. 1/3 or more of the blending amount of As described above, the use of the liquid composition not only facilitates the manufacturing process of cosmetics, but also makes it possible to mix it with any cosmetics. Further, in the case of blending with the polyhydric alcohol ester of rosin without treatment, the blending amount of the dialcohol ester of dibasic acid may be 1/2 or more of the blending amount of the polyhydric alcohol ester of rosin.

What is meant by the cosmetics in the present invention is any cosmetics as long as it is a cosmetic that requires the addition of a polyhydric alcohol ester of rosin, for example, lipstick, eyeliner, mascara, eye shadow, foundation, manicure, etc. Various makeup cosmetics, various hair cosmetics such as set lotion, hair spray, hair cream, pomade, and tic, and various basic cosmetics such as cream and emulsion.
