Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an oil-

The present invention relates to an oil dispersion type cosmetic composition containing a high concentration of a powder having excellent skin durability.

Conventional methods for stabilizing the powder on the oil phase include a method of producing a solid by increasing the hardness of the trauma as an oil-wax-powder system, and a method of dispersing the powder uniformly using a surfactant other than that required for emulsification Have been used.

Wax is used] has a disadvantage in that a heavy use feeling and a thick cosmetic film are formed. The higher the content of the powder, the lower the degree of dispersion and the uniformity of application is lowered and there is a disadvantage that it has a stiff feeling. In addition, when the surfactant is used [Patent Documents 1 and 2], when an oil gelling agent or a surfactant is used excessively in an emulsion having water and oil as internal and external surfaces, dispersion of the powder is maintained but spreadability is poor, There is a disadvantage in terms of usability such as sticky or greasy residue.

In order to solve this problem, an oil dispersing method has been developed in which an oil gelling agent is added without using wax to disperse the powder in an oil having hardness. [Patent Document 3] The oil dispersing system has a high covering force It is changed from solid to gel and smoothed more smoothly, and it has the advantages of moisturizing and light feel. However, when the content of the powder is increased, the skin adhesion of the cosmetic composition is lowered, and cosmetic ingredients are pushed out onto the surface of the skin.

The present invention relates to an oil-dispersed cosmetic composition comprising a film-forming agent, an oil, an organic thickener, a powder and a feeling-controlling agent.

The film-forming agent serves to improve skin adhesion, and examples of the film-forming agent include dextrin isostearate, polyvinyl pyrrolidone, polyurethane, acrylate copolymer, acrylamide copolymer, nitrocellulose, Polytetrafluoroethylene, and polyquaternium. The film-forming agent may be used in an amount of 1 to 50 parts by weight, preferably 5 to 30 parts by weight, based on 100 parts by weight of the total cosmetic composition. If the content is less than 1.0 part by weight, the adhesiveness of the powder may be lowered and the skin adhesion force of the powder may be lowered. If the content is more than 50 parts by weight, the feeling of use may be deteriorated due to excessive stickiness.

The present invention is an oil dispersion formulation comprising water and a surfactant but not volatile oil or volatile silicone oil, a nonvolatile oil, a film former, an organic thickener, a powder and a feeling control agent.

The oil that can be used in the oil dispersion form according to the present invention is preferably a mixture of volatile oil and nonvolatile oil suitably used in an amount of 1.5 to 50 parts by weight per 100 parts by weight of the entire cosmetic composition, Is from 11 to 40 parts by weight.

The volatile oil may be at least one selected from volatile oils of hydrocarbon series such as paraffin and isoparaffin, and volatile silicone oil. Specific examples of the hydrocarbon-based volatile oils include isododecane, C7-8 isoparaffin, C8-9 isoparaffin, C10-11 isoparaffin, C11-12 isoparaffin, C12-20 isoparaffin, C13-14 isoparaffin Etc., and specific examples of the volatile silicone oil may be at least one selected from cyclomethicone, cyclotetrasiloxane, and cyclopentasiloxane. The volatile oil may be used in an amount ranging from 1 to 30 parts by weight, preferably from 10 to 25 parts by weight, based on 100 parts by weight of the total cosmetic composition. When used in an amount of less than 1 part by weight, the volatility is too low to cause the effect of the powder to be obtained. When the powder is used in an amount exceeding 30 parts by weight, the powder has a light feeling, .

Examples of the nonvolatile oil include hydrogenated polydecene, polyisobutene, lanolin oil, squalane, liquid paraffin, caprylic / capric triglyceride, butylene glycol dicaprylate, hexyl laurate, isocetyl myristate, iso Propyl myristate and isopropyl palmitate may be used. These may be used in an amount of 0.5 to 20 parts by weight, preferably 1 to 15 parts by weight, based on 100 parts by weight of the entire cosmetic composition. When it is used in an amount of less than 0.5 part by weight, there is a problem that the powder on the surface of the skin becomes dry and white, and when it is used in excess of 20 parts by weight, the effect of the bundled powder is not exhibited.

Examples of the organic thickener include dextrin palmitate, dextrin palmitate / ethylhexanoate, stearoyl inulin, polyglyceryl-8 beeswax, ethylenediamine / stearyl dimer dilinoleate copolymer, polyamide-8 and glyceryl Behenate, and eicosadioate, and may be used in an amount of 0.01 to 15 parts by weight, preferably 0.1 to 10 parts by weight, based on 100 parts by weight of the entire cosmetic composition. If the content is less than 0.01 part by weight, the effect of increment may be insignificant. If the content is more than 15 parts by weight, the viscosity becomes too high, which may result in poor formulation stability and feeling of use.

The powder can be used in any form as long as it is used in ordinary cosmetics, regardless of its shape (spherical, acicular, or platy), particle size (fine particles, pigment, etc.), particle structure (porous room, Examples of the organic powders include polymethylmethacrylate, nylon, cellulose, polyethylene, silk powder and the like. Examples of the inorganic powder include titanium oxide, zinc oxide, iron oxide (yellow, red, black and the like), talc, mica, polymethylsilsesquioxane (porous silica), silica dimethylsilate, sericite, . It is also possible to use powders obtained by compounding such powders or surface-treating them with oil, silicone, fluorine or the like.

The compounding amount of the powder can be varied according to the formulation, and it can be generally used in the range of 2 to 60 parts by weight, preferably 15 to 60 parts by weight based on 100 parts by weight of the whole cosmetic composition. If the amount is less than 2 parts by weight, the effect of the powder may not be exhibited. If the amount is more than 60 parts by weight, the viscosity becomes too high and the dispersion of the oil phase may not be achieved. Any of these organic powders and inorganic powders may be used alone or in combination, and the present invention is not limited thereto.

Examples of the use feeling regulator include a silicone elastomer, specifically, a mixture of cyclopentasiloxane and dimethicone / vinyl dimethicone crosspolymer; A mixture of dimethicone and dimethicone / vinyl dimethicone crosspolymer; Mixtures of cyclopentasiloxane and dimethicone / vinyl dimethicone crosspolymer; A mixture of dimethicone and dimethicone / phage-10/15 crosspolymer; And a mixture of cyclopentasiloxane and dimethicone crosspolymer may be used, and it may be used in an amount of 2 to 50 parts by weight, preferably 5 to 35 parts by weight, based on 100 parts by weight of the whole cosmetic composition. When the amount of the cosmetic is less than 2 parts by weight, the feeling of use can not be improved when the cosmetic is applied to the skin. When the amount exceeds 50 parts by weight, the skin adhesion of the cosmetic is impaired and the skin is pushed out.

The oil-dispersible cosmetic composition of the present invention may contain, in addition to the essential components described above, general components used according to the purpose of use. For example, a polar or non-polar oil for control of feeling, a dispersing agent for flowability and dispersion efficiency, a surfactant, a pigment for controlling cosmetic effect and usability and a preservative, an ultraviolet absorber, a polymer, a fatty acid alcohol and a perfume . Any of the above-mentioned ingredients may be blended to the extent that the object and effect of the present invention are not impaired, but is preferably 0.01 part by weight to 8.0 parts by weight based on 100 parts by weight of the entire cosmetic composition By weight, more preferably 0.01 to 4.0 parts by weight. The amount of the above components can be easily selected as needed.

The cosmetic composition of the present invention can be produced by combining functions of ultraviolet screening agent, wrinkle, and whitening in order to impart functionalities. Therefore, ultraviolet screening agents, wrinkles and whitening agents are added to the composition according to the present invention, Can be given.

The oil-dispersible cosmetic composition according to the present invention can be used for cosmetic preparations such as lotions, creams, primers and the like, and base makeups for face powders, compacts, powder foundations, two-way cakes, makeup bases, liquid foundation, And make-ups of point make-up such as eyeshadow, powder blush, lipstick, eyeliner, and mascara.
