Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a specific liquid oil, a fluorine-based oil, glycols, powder, a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer. More particularly, the present invention relates to obtaining an oil-based cosmetic having excellent dispersibility, usability, and finish of the system, and having excellent makeup durability. [0002] Conventionally, oily cosmetics such as lipstick, eyeliner, eyeshadow, oily foundation, etc., have difficulty in satisfying good usability and long-lasting makeup at the same time, and emphasize emphasis on usability and finish. Had the drawback that they had poor makeup durability and tended to adhere to clothes and cause bleeding. Various studies have been made in the past to solve this drawback. For example, a dye compounded to improve cosmetic durability by dyeing on the lips, a solid compound such as wax is added to strengthen the coating to reduce color transfer, a volatile oil agent and a film Compounding a forming agent, removing the color transfer by leaving the pigment and wax etc. by volatilizing the volatile oil after application, compounding a fluorine-based oil, imparting water and oil repellency, Examples include those having improved color durability. [0003] However, those containing a dye are easy to dry in the coated part with the lapse of time, and those containing a large amount of wax have a large elongation and poor usability. Further, those containing a volatile oil agent and a film-forming agent are not glossy over time after application, and the application part is dried. Furthermore, since the fluorine-based oil has poor compatibility with other oils, it has a drawback that it is difficult to uniformly disperse it in a system having a large oil content. [0004] Under such circumstances, the present inventors have conducted intensive studies and as a result, have found that specific liquid oils, fluorine oils, glycols, powders, carboxyvinyl polymers and / or alkyls. The present inventors have found that an oil-based cosmetic containing a modified carboxyvinyl polymer is excellent in system dispersibility, usability and cosmetic durability, and have completed the present invention. That is, the present invention provides the following components (A), (B),
(C), (D) and (E); (A) an oily base having an IOB value of 0.2 or more and liquid at ordinary temperature (B) a fluorinated oil (C) glycols (D) powder (E) ) An oil-based cosmetic comprising a carboxyvinyl polymer and / or an alkyl-modified carboxyvinyl polymer. As the oily base of the component (A) used in the present invention, any one can be used as long as it has an IOB value of 0.2 or more and is liquid at ordinary temperature. Examples thereof include diglyceryl triisostearate, glyceryl trioctanoate, triglyceride 2-ethylhexanoate, propylene glycol dicaprate, oleyl alcohol, and castor oil. One or more of these can be used as necessary. The oily base of the component (A) of the present invention is blended in the oily cosmetic in an amount of 0.5 to 90% by weight (hereinafter simply referred to as "%"). Within this range, good dispersibility and longevity can be obtained, but outside this range, the dispersibility of the system is not preferred. The fluorinated oil component (B) used in the present invention is a perfluoro organic compound which is liquid at room temperature, such as perfluoroalkane and perfluoropolyether represented by the following general formula (1). And the like. [0007] Wherein R ¹ , R ² , R ³ , R ⁴ and R ⁵ are the same or different and each represents a fluorine atom, a perfluoroalkyl group or an oxyperfluoroalkyl group;
p, q and r each represent an integer of 0 or more giving a molecular weight of 500 to 100,000. (However, p = q = r = 0 is not satisfied.) Here, the perfluoro groups shown in parentheses need not be arranged in this order, and may be random polymerization or block polymerization. As such perfluoropolyether, one having a viscosity of 5 to 5,000 cSt is particularly preferable. For example, the following general formula (2) is used. (Wherein m and n are molecular weights 500 to 10,
000, where n / m is 0.2-2)
FOMBRIN HC as a commercial product
-01, HC-02, HC-03, HC-04,
HC-25 and HC-R (all manufactured by Montefluos), and the following general formula (3): (Wherein, l represents a number from 4 to 500), and as commercial products, Demnum S-20 and S-
65, S-100 and S-200 (manufactured by Daikin Industries, Ltd.). These fluorinated oils are
One or more kinds can be used as needed.
The fluorine-based oil agent of the component (B) of the present invention is blended in an oily cosmetic in an amount of 0.01 to 5%. Within this range, good usability and dispersibility can be obtained. If it is less than 0.01%, the effect cannot be sufficiently obtained, and if it exceeds 5%, it is not preferable in terms of dispersibility. As the glycols of the component (C) used in the present invention, any of those usually used in cosmetics can be used. For example, glycerin, 1,3-butylene glycol, dibutylene glycol and the like can be used. No.
One or two or more of these glycols can be used as needed. The glycol of the component (C) of the present invention is blended in the oily cosmetic in the range of 0.01 to 5%. Within this range, good usability and long-lasting makeup can be obtained. If it is less than 0.01%, the effect cannot be sufficiently obtained, and 5%
Is not preferable. The powder of the component (D) used in the present invention comprises:
Any one can be used as long as it is commonly used in cosmetics, for example, extenders such as talc, sericite, mica, kaolin, silica, nylon powder, polyethylene powder, cellulose powder, carbon black, titanium oxide, zinc oxide , Ultramarine, navy blue, chromium oxide,
Organic tar dyes, colorants such as lakes, composite pigments such as mica titanium and iron oxide coated mica, and dyes such as Red No. 218, Red No. 223, Orange No. 201, Yellow No. 201, Purple No. 201, and the like. In addition, those obtained by subjecting these powders to surface treatment with silicone, higher fatty acids, higher alcohols, fatty acid esters, metal soaps, amino acids, alkyl phosphates or fluorine compounds can be used. One or more of these powders can be used as needed. The powder of the component (D) of the present invention is blended in the oily cosmetic in the range of 0.1 to 80%. Within this range, good usability and long-lasting makeup can be obtained. 0.1%
If the amount is less than 80%, the effect cannot be sufficiently obtained. As the carboxyvinyl polymer and / or alkyl-modified carboxyvinyl polymer of the component (E) used in the present invention, any of those usually used in cosmetics can be used. For example, Carbopol 940, 941, 1342, Pemulen TRI,
Those commercially available as the same TRII (both manufactured by BF Goodrich) can be used, and one or two or more can be used as necessary. Conventionally, these polymers are blended into cosmetics as a water-swelled product, but it is desirable to blend them in a powder form in consideration of realizing the effect. The carboxyvinyl polymer and / or alkyl-modified carboxyvinyl polymer of the component (E) of the present invention is blended in an oily cosmetic in an amount of 0.01 to 10%.
Within this range, good usability and long-lasting makeup can be obtained.
If less than 0.01%, sufficient makeup lasting cannot be obtained and 10%
When it exceeds, it is not functionally preferable. The oily base used in the present invention, other than the component (A), is not particularly limited, such as solid, semi-solid and liquid oils which are generally used. Animal oils, vegetable oils, mineral oils, synthetic oils, etc. Regardless of the oil, hydrocarbons, oils and fats, waxes, esters, fatty acids, higher alcohols, silicone oils, fluorine-based oils, lipophilic surfactants and the like can be mentioned. For example, polybutene, vaseline, paraffin wax, ceresin wax, microcrystalline wax, synthetic hydrocarbon wax, beeswax, carnauba wax, candelilla wax, dimethylpolysiloxane, methylphenylpolysiloxane, methylhydrogenpolysiloxane, three-dimensional crosslinked structure A dimethylpolysiloxane polymer having the following formula (1) can be used, and if necessary, one kind or two or more kinds can be appropriately selected depending on the product form. The oil-based cosmetic of the present invention contains, in addition to the above components,
As long as the effects of the present invention are not impaired, powders, surfactants, antioxidants, polymer compounds, fragrances, preservatives, ultraviolet absorbers, humectants, cosmetic ingredients, and the like commonly used in cosmetics are blended. can do.
