DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an oil gel cosmetic, and more particularly to an oil gel cosmetic containing a cholesterol fatty acid ester which may be hydrogenated and sucrose acetate isobutyrate.

[0002]

2. Description of the Related Art In oil gel cosmetics such as lipsticks, adhesion to tea cups, cigarettes and the like has been a bigger problem than before. These deposits are not only aesthetically pleasing, but also the secondary deposits attached to the cups and the like are difficult to wash, and stains clothes when handling these dirty dishes, etc., This is a phenomenon that causes many disadvantages to the cosmetic act, such as the cosmetics falling off from the site where the cosmetics are applied due to these adhesions and the cosmetic finish is significantly impaired.

[0003] Under such circumstances, various attempts have been made to suppress or prevent the adhesion phenomenon of cosmetics. For example, using a polyethylene or synthetic polymer, it creates a tough film of the cosmetic to prevent falling off, blends a water-soluble polymer and a laked dye into an oil gel cosmetic to prevent color transfer, Attempts have been made to coat with substances that are poorly soluble in water and oil.

However, in the method of forming a film of a cosmetic such as a polymer, the film is too strong, so that the skin is closed and the skin tends to be rough, and the cosmetic effect such as luster is easily impaired. In the combination of polymer and laked pigment, the color of the ground becomes dirty due to the dyeing of the laked pigment due to the weeping, and coating with perfluorocarbon etc. gives a strong sense of discomfort to the skin and unnatural gloss derived from perfluorocarbon. Therefore, the makeup effect was easily damaged.

On the other hand, an oil gel containing a cholesterol fatty acid ester which may be hydrogenated and a sucrose acetate isobutyrate ester can form a preferable cosmetic film.
It was not known to mix these in an oil gel.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and therefore, it is an object of the present invention to provide an oil gel cosmetic which does not impair the skin or the finish of makeup and which is not easily adhered to a cup or the like. As an issue.

[0007]

Means for Solving the Problems In order to develop an oil gel cosmetic which does not easily adhere to a cup or the like and does not impair the skin and the cosmetic effect, the present inventors have studied combinations of raw materials for various cosmetics. As a result, they found that a cosmetic film containing a cholesterol fatty acid ester which may be hydrogenated and sucrose acetate isobutyrate has such properties, and completed the invention. Hereinafter, the present invention will be described in detail.

(1) Oil gel cosmetic of the present invention The oil gel cosmetic of the present invention is characterized by containing a cholesterol fatty acid ester which may be hydrogenated and sucrose acetate isobutyrate. Here, the cholesterol fatty acid ester which may be hydrogenated is cholesterol which may be hydrogenated, that is, a cholesterol and / or dihydrocholesterol in which a hydroxyl group and a carbonyl group of a fatty acid are ester-bonded,
It is already widely marketed. Here, the fatty acid is a fatty acid having 2 to 22 carbon atoms, which may be linear or branched.
Among such cholesterol fatty acid esters which may be hydrogenated, a preferable one is a mixture of dihydrocholesteryl oleate, dihydrocholesteryl butyrate, cholesteryl nonanoate and cholesteryl butyrate.
LE-S (commercially available, manufactured by Yoshikawa Essential Oil Co., Ltd.). This substance contains water and easily forms liquid crystals, and has a function of imparting water retention to a strong decorative film. Yofco CLE-S is excellent in such an effect. The preferred content of the optionally hydrogenated cholesterol fatty acid ester in the cosmetic of the present invention is 1 to 10% by weight. If the amount is less than 1% by weight, such a water retention effect is not remarkable, and if the amount exceeds 10% by weight, the effect peaks and the amount of other components is limited, which is not preferable. More preferred content is 1 to
5% by weight.

[0009] Sucrose acetate isobutyrate has long been used as a film-forming agent. For example, SAIB100S sold by Eastman Chemical Company can be suitably exemplified. In the present invention, the preferred amount of sucrose acetate isobutyrate is 5 to 30% by weight.
If the amount is less than 5% by weight, such a water retention effect is not remarkable, and if the amount exceeds 30% by weight, the effect is flattened out and the amount of other components is limited, which is not preferable. A more preferred content is 10 to 20% by weight.

The oil gel cosmetic of the present invention may contain various optional components generally used in cosmetics in addition to these essential components. Optional components include, for example, microcrystalline wax, petrolatum, squalane,
Hydrocarbons such as polyethylene, olive oil, castor oil,
Triglycerides such as tallow, coconut oil, jojoba oil, carnauba wax, esters such as beeswax, higher fatty acids such as stearic acid and behenic acid, stearyl alcohol,
Higher alcohols such as cetanol, surfactants such as monoglyceride stearate, monoglyceride oleate, and sorbitan monooleate; antioxidants such as tocopherol and butylhydroxytoluene; Red No. 104, Red No. 202, Red No. 226, Yellow No. 4 And inorganic pigments such as red iron oxide and yellow iron oxide; powders such as titanium mica, mica and talc; polyhydric alcohols such as glycerin and 1,3-butanediol; and ultraviolet absorption such as para-aminobenzoic acid derivatives. And the like. If these essential components and optional components are treated by a usual method, the oil gel cosmetic of the present invention can be obtained. The type of cosmetic is not particularly limited as long as the oil gel cosmetic can be applied, and examples thereof include lipstick, blusher, Mayuzumi, mascara, eyeliner, foundation, and lip balm.

(2) Characteristics of the Cosmetic of the Present Invention The cosmetic of the present invention obtained in this manner forms a strong decorative film capable of retaining water. Despite being small, it does not cause undesired reactions on the skin such as rough skin. This is because the cholesterol fatty acid ester which may be hydrogenated and the sucrose acetate isobutyrate contained in the oil gel impart a water retention function to a strong film. Hereinafter, this effect will be described in detail with reference to an experimental example of water retention of the membrane.

(Experimental example) A sample shown in Table 1 below was applied to the lips, and after 30 minutes, the conductance was measured using a skicon of IBS.
200. The results are shown in Table 1. This indicates that the combination of a cholesterol fatty acid ester, which may be hydrogenated, and sucrose acetate isobutyrate is combined to increase conductance and improve water retention. This hinders the occurrence of undesired phenomena on the skin such as rough skin due to blockage, and can be expected to provide excellent safety.

As described above, the oil gel cosmetic of the present invention not only has excellent water retentivity, but also has a high transparency and an appropriate gloss of the formed film. .

Example 5 Secondary Adhesion Comparative Test The secondary adhesion to tea cups and the secondary adhesion to cigarettes were compared for Comparative Examples 1 to 3 and Examples 1 to 4 shown below. That is, each lip was applied to five panelists, and a cigarette and a cup were added 30 minutes after the application. The tobacco and the cup were collected, and the secondary adhesion amount of the lip color was determined according to the following criteria and compared. That is, +: clear secondary adhesion, ±: slight secondary adhesion,-: reference for no secondary adhesion. Table 2 shows the results. From this, it can be seen that the lip color of the present invention is extremely unlikely to cause secondary adhesion.

[Table 2]

Example 6 Actual use test Ten female panelists used the lip color of Example 1 continuously for one week continuously, and used a questionnaire to determine the degree of secondary adhesion to cups and cigarettes and the condition of lips. I got a comparative evaluation with the lip color. Table 3 shows the results. From this, it can be seen that the lip color of the present invention does not easily cause secondary adhesion and is preferable for the lip condition. This is because the strong film made of the cholesterol fatty acid ester and the sucrose acetate isobutyrate has an excellent water retention function as shown in the experimental examples.
