Description

The present invention relates to a cosmetic, and more particularly to a base cosmetic.

  Background cosmetics are cosmetics that are used before using foundations such as powder foundations and liquid foundations. The purpose of use is for the surface of the skin such as peeling of horny layer cells called “powder balloons”. For example, there are preparations for roughening, improvement of the foundation and the like, and adjustment of the skin color before using the foundation. However, foundations and the like may float under intense sweating conditions in the summer, and there has been a demand for a foundation cosmetic with better sweat resistance. A technique using a fluorine-containing polymer is known to improve the sweat resistance of a makeup cosmetic (see, for example, Patent Document 1). However, in a base cosmetic, the water and oil repellency is applied to the skin. In some cases, sufficient adhesion was difficult to obtain. Here, pyrrolidone carboxylic acid-modified polysiloxane is a compound in which pyrrolidone carboxylic acid is bonded to the main chain of polysiloxane, and can impart moisture retention to lipstick as a hydrophilic silicone (for example, see Patent Document 2), powder It is known that impact resistance can be imparted to body cosmetics (see, for example, Patent Document 3) and that it has a surface active action that can form a water-in-oil emulsion (see, for example, Patent Document 4). Polyglycerin fatty acid esters are those in which fatty acids are ester-bonded to polyglycerin, and can be used as a surfactant with a low risk of aldehyde generation (see, for example, Patent Document 5). It is known that an emulsion composition excellent in stability can be obtained (see, for example, Patent Document 6), and an external preparation with secondary adhesion suppressed in combination with lecithin (see, for example, Patent Document 7). ing. However, cosmetics containing pyrrolidone carboxylic acid-modified polysiloxane and polyglycerin fatty acid ester are not known. By containing pyrrolidone carboxylic acid-modified polysiloxane and polyglycerin fatty acid ester, adhesion to the skin and sweat resistance It has not been known at all that an excellent base cosmetic material can be obtained.

  It was an object to obtain a base cosmetic that does not easily lose its makeup.

  The inventors of the present invention have found that by containing a pyrrolidone carboxylic acid-modified polysiloxane and a polyglycerin fatty acid ester, a base cosmetic that does not easily cause makeup collapse is obtained. That is, the present invention is as follows.

(1) A cosmetic comprising pyrrolidone carboxylic acid-modified polysiloxane and polyglycerin fatty acid ester.
(2) The cosmetic according to (1), wherein the polyglycerol fatty acid ester is decaglycerol fatty acid ester.
(3) The cosmetic according to (1) or (2), wherein the polyglycerol fatty acid ester is decaglycerol triisostearate.
(4) The cosmetic according to any one of claims 1 to 3, further comprising a carboxyvinyl polymer which may be alkyl-modified.
(5) The cosmetic according to any one of (1) to (4), which is an emulsified composition.
(6) The cosmetic according to any one of (1) to (5), which is an oil-in-water emulsion composition.
(7) The cosmetic according to any one of (1) to (6), which is a base cosmetic.

  ADVANTAGE OF THE INVENTION According to this invention, the cosmetics for base | substrates with which makeup collapse does not occur easily can be provided.

1) Pyrrolidone carboxylic acid modified polysiloxane which is an essential constituent of the present invention The cosmetic of the present invention is characterized by containing pyrrolidone carboxylic acid modified polysiloxane as an essential constituent. The pyrrolidone carboxylic acid-modified polysiloxane is one in which a pyrrolidone carboxylic acid group is introduced into a part of the dimethylpolysiloxane skeleton, and has already been used as a raw material for cosmetics, and there are commercially available products. As such a commercial item, "Monacyl PCA (trademark)" marketed from Unikema Corporation can be illustrated, and this can be purchased and used, and is preferable. In the cosmetic of the present invention, the pyrrolidone carboxylic acid-modified polysiloxane is preferably contained in an amount of 0.01 to 3% by mass, more preferably 0.03 to 1% by mass, based on the total cosmetic. It is more preferable to contain -0.5 mass%. This is because if the content of the pyrrolidone carboxylic acid-modified polysiloxane is too much or too little, the effects of the present invention are hardly obtained.

2) Polyglycerol fatty acid ester which is an essential constituent of the present invention The cosmetic of the present invention is characterized by containing a polyglycerol fatty acid ester. As the polyglycerin fatty acid ester according to the present invention, polyglycerin fatty acid esters usually used in cosmetics and the like can be used. The polyglycerin used in such polyglycerin fatty acid ester preferably has a degree of polymerization of 4 to 10, and the type of fatty acid is preferably a linear, branched or unsaturated fatty acid having 10 to 22 carbon atoms. The number of moles of fatty acid added to glycerin is preferably 1-6. Such polyglycerol fatty acid esters include decaglycerol monolaurate, decaglycerol monostearate, decaglycerol monoisostearate, decaglycerol monooleate, decaglycerol distearate, decaglycerol diisostearate, decaglycerol Glycerol tristearate, decaglycerin triisostearate, decaglycerin trioleate, decaglycerin pentastearate, decaglycerin pentaisostearate, decaglycerin pentaoleate, hexaglycerin monolaurate, hexaglycerin mono Stearate, hexaglycerin monooleate, hexa Li serine triisostearate ester, tetraglycerol monostearate, tetraglycerol monooleate, since such tetraglycerol tristearate phosphoric acid esters are commercially available, can be preferably used to purchase these things. In the present invention, such a polyglycerin fatty acid ester preferably contains only one species or a combination of two or more species. Among these polyglycerin fatty acid esters, it is preferable to use a branched fatty acid ester of decaglycerin, and specifically, decaglycerin triisostearic acid ester, decaglycerin diisostearic acid ester, and decaglycerin monoisostearic acid ester are preferably used. . This is because such a decaglycerin isostearic acid ester is used together with pyrrolidone carboxylic acid-modified polysiloxane, whereby adhesion effects such as foundation are particularly improved. In the cosmetic of the present invention, such a polyglycerin fatty acid ester is preferably contained in an amount of 0.01 to 5% by mass, more preferably 0.03 to 3% by mass, based on the entire cosmetic. It is more preferable to contain 0.05-1 mass%. This is because the effect of the present invention is hardly obtained if the content of the polyglycerin fatty acid ester is too much or too little.

3) Cosmetics of the present invention The cosmetics of the present invention contain pyrrolidonecarboxylic acid-modified polysiloxane and polyglycerin fatty acid ester with respect to the entire cosmetics, so that makeup cosmetics such as powder foundations are applied to the skin. It has a feature that the sticking is improved and the make-up collapse is less likely to occur even with sweat.

  The cosmetic of the present invention preferably contains a carboxyvinyl polymer which may be further alkyl-modified and / or a salt thereof in addition to pyrrolidone carboxylic acid-modified polysiloxane and polyglycerin fatty acid ester. By containing such a component, fine roughness of the skin surface is adjusted, and the adhesion effect such as foundation is further improved. Since various carboxyvinyl polymers are commercially available as thickeners, they can be purchased and used. The alkyl-modified carboxyvinyl polymer is a polymer in which an alkyl group is introduced into a part of the carboxyvinyl polymer. For example, “Pemylene TR-1”, “Pemylene TR-2”, “Carbopol 1382” from Goodrich (USA). Are commercially available, and these can be purchased and used.

  In the cosmetic of the present invention, it is preferable to apply a makeup cosmetic such as a foundation after applying the cosmetic of the present invention to the skin. That is, it is preferably used as a foundation cosmetic such as an undermake in a makeup act. This is because the cosmetic of the present invention is applied to the skin, and it has the effect of improving the adhesion and sweat resistance of makeup cosmetics such as powder foundation and emulsified foundation that are used repeatedly. is there.

  The cosmetic of the present invention contains a pyrrolidone carboxylic acid-modified polysiloxane and a polyglycerin fatty acid ester, which are substances having an affinity for water and oil as essential components, and a preparation containing an aqueous component and an oil component. Since it can be applied, it is preferably applied to an emulsified composition, and more preferably used as a base for make-up cosmetics. Therefore, it is more preferable to make the oily water-in-water emulsion composition feel good.

  In addition to the above components, the cosmetic of the present invention may further have a surface treated, mica, talc, kaolin, synthetic mica, calcium carbonate, magnesium carbonate, anhydrous silicic acid (silica), aluminum oxide, barium sulfate, etc. Powders, the surface of which may be treated, bengara, yellow iron oxide, black iron oxide, cobalt oxide, inorganic pigments of ultramarine, bitumen, titanium oxide, zinc oxide, red 202 which may be raked No., Red 228, Red 226, Yellow No. 4, Blue No. 404, Yellow No. 5, Red No. 505, Red No. 230, Red No. 223, Orange No. 201, Red No. 213, Yellow No. 204, Yellow No. 203, Organic dyes such as Blue No. 1, Green No. 201, Purple No. 201, Red No. 204, polyethylene powder, polymethyl methacrylate, nylon powder, organopolysiloxane elastomer And organic powders such mer or the like is added, it is also effective use of the present invention to provide a color correction effect.

<Test Example 1> Evaluation 1 of makeup holding under severe conditions
In 12 subjects, after washing the face, the cosmetic 1, the cosmetic 2, the comparative example 1, the comparative example 2, the comparative example 3 and the creams of the comparative example 3 in Example 1 are not applied (no application). 2 were selected so as not to overlap each other, 0.5 g of each cream was used on one face, and then the foundation was used on all faces. Then, they were allowed to rest for 2 hours in a room at 32 ° C. and 80% humidity, and evaluated for makeup collapse. The evaluation was performed by two expert evaluators based on the evaluation criteria described in Table 1 below using “dullness”, “shine”, and “buzz” as indices. That is, for each sample, 4 or 5 sites were evaluated by 2 people, and the values were averaged. The evaluation results are shown in Table 2.

  From the results shown in Table 2, when the non-application and Comparative Example 3 were compared, the cosmetic durability was slightly improved, and the basic effect as a base cosmetic was recognized in Comparative Example 3. Further, in Comparative Example 3, in Comparative Example 2 in which a part of water was substituted with decaglycerin triisostearate, and in Comparative Example 2 in which a part of squalane was substituted with pyrrolidone carboxylic acid-modified methylpolysiloxane, the longevity was further improved. The cosmetic 1 containing pyrrolidonecarboxylic acid-modified methylpolysiloxane and decaglycerin triisostearate, and the cosmetic 2 containing pyrrolidonecarboxylic acid-modified methylpolysiloxane and decaglycerin monoisostearate are more prominent than the comparative examples. The improvement of long-lasting makeup was recognized. That is, the cosmetics 1 and 2 were found to have a significant improvement in cosmetic durability due to the inclusion of pyrrolidonecarboxylic acid-modified methylpolysiloxane and polyglycerin fatty acid ester.
