BACKGROUND OF THE INVENTION
The present invention relates to a water-in-oil emulsified cosmetic that exhibits a good emulsified state, is excellent in stability over temperature and time, has a good feeling in use, and has a high makeup sustainability.
[0002]
[Prior art]
Conventionally, water-in-oil emulsified cosmetics ensure the temporal stability of cosmetics by blending solid fats such as wax and semi-solid fats into the oil phase, which is a continuous phase, and increasing the viscosity of the oil phase. Was. However, when a wax or the like is blended, the viscosity of the composition becomes high, so that there is a problem in terms of use feeling such as an increase in stretch and a sticky feeling. In addition, waxes such as solid fat and semi-solid fat have high water repellency but low oil repellency, so they easily mix with sebum and contribute to makeup loss such as shine and color dullness.
[0003]
On the other hand, for the purpose of imparting water resistance and sebum resistance (water repellency / oil repellency), cosmetics containing liquid perfluoropolyethers (JP 61-234928, JP 63-107911) and A makeup base (Japanese Patent Laid-Open No. 7-196446) using perfluoropolyether and silica powder has been proposed. However, when perfluoropolyether is used as a non-volatile oil, there is a problem that although it has water resistance and sebum resistance, the affinity with the skin is low and the cosmetic ingredients are easily lost from the skin.
[0004]
Furthermore, in order to improve makeup persistence, it has been proposed to use a fluorine-modified silicone having high skin affinity and excellent water / oil repellency (Japanese Patent Laid-Open No. 6-184312). However, in water-in-oil emulsified cosmetics using these, it is difficult to ensure the stability of emulsification over time, and the stability of the emulsion over time has been ensured by increasing the viscosity of the emulsion. It was difficult to get.
[0005]
[Problems to be solved by the invention]
An object of the present invention is to provide a water-in-oil emulsified cosmetic having good emulsification stability, good spread, less stickiness and excellent makeup sustainability.
[0006]
[Means for Solving the Problems]
The present inventor is excellent in emulsification stability over time in a wide temperature range by combining fluorine-modified silicone, hydrophilic silica having a specific particle size, a nonionic surfactant having an HLB of 6 or less and an oil agent in a specific ratio. It was found that a water-in-oil emulsified cosmetic with good spread and good stickiness and good use feeling and high makeup persistence can be obtained.
[0007]
The present invention includes the following components (A) to (E):
(A) Fluorine-modified silicone 1 to 50% by weight,
(B) 0.1 to 5% by weight of hydrophilic silica having an average particle size of 0.01 to 0.2 μm,
(C) 0.05 to 10% by weight of nonionic surfactant of HLB 1 to 6,
(D) Oil agent other than component (A) 1 to 50% by weight,
(E) Water 20-70% by weight
A water-in-oil emulsified cosmetic containing
[0008]

The component (A) fluorine-modified silicone used in the present invention has a dimethylpolysiloxane skeleton and a perfluoroalkyl group in the molecule. For example, the following general formulas (1) and (2)
[0009]
[Chemical 1]

[0010]
[In the formula, R _f represents a C 1-20 perfluoroalkyl group or a ω-H-perfluoroalkyl group represented by the formula H (CF ₂ ) _k- (k represents an integer of 1-20). , R represents a hydrocarbon group having 2 to 16 carbon atoms, and R ¹ , R ² and R ³ are the same or different and represent a linear or branched aliphatic hydrocarbon group having 1 to 20 carbon atoms or a carbon number Represents an alicyclic or aromatic hydrocarbon group of 5 to 10, m is an integer of 2 to 16, n is an integer of 1 to 6, x is an integer of 0 to 50, p is an integer of 1 to 200, q is Represents an integer of 0-200]
And fluorine-modified silicones having two types of siloxane units represented by general formula (3).
[0011]
[Chemical 2]

[0012]
[In the formula, R _{f ′} represents CH ₃ or R _{f ″} CH ₂ CH ₂ , and at least one is R _{f ″} CH ₂ CH ₂ (where R _{f ″} is a perfluorocarbon having 1 to 9 carbon atoms. An alkyl group), x represents an integer of 1 to 400]
[0013]
In the general formulas (1) and (2), the perfluoroalkyl group represented by R _f may be linear or branched, and is particularly preferably a linear perfluoroalkyl group having 3 to 9 carbon atoms. R is preferably a linear or branched alkylene group having 2 to 5 carbon atoms, particularly an ethylene group or a propylene group. R ¹ , R ² and R ³ include, for example, a straight chain alkyl group such as a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, a hexyl group, a heptyl group, an octyl group, a nonyl group, a decyl group; an isopropyl group , Sec-butyl group, tert-butyl group, neopentyl group, 1-ethylpropyl group, 2-ethylhexyl group and other branched alkyl groups; cyclopentyl group, cyclohexyl group and other cyclic alkyl groups; phenyl naphthyl group and other aromatic hydrocarbons A straight chain alkyl group having 1 to 3 carbon atoms is particularly preferable.
[0014]
Further, as the fluorine-modified silicone represented by the general formula (3), those in which R _{f ″} is a perfluorobutyl group are preferable. X is usually preferably 2 to 200.

[0016]
As the component (A), one or more kinds can be used, and 1 to 50% by weight, preferably 1 to 30% by weight, is contained in the whole composition. Within this range, sufficient makeup persistence can be obtained, and a refreshing feel can be obtained with an appropriate oily feeling.
[0017]
The component (B) hydrophilic silica has an average particle size of 0.01 to 0.2 μm. When the average particle size exceeds 0.2 μm, the spread becomes heavy in the feeling of use or a rough feeling is produced, which is not preferable. As a commercial item, Aerosil 200, 300 (above, Nippon Aerosil Co., Ltd.) etc. are mentioned, for example.
[0018]
Component (B) is contained in the total composition in an amount of 0.1 to 5% by weight, preferably 0.1 to 2% by weight, from the viewpoint of emulsion stability and usability. If it is less than 0.1% by weight, sufficient emulsification stability cannot be obtained, and if it exceeds 5% by weight, the viscosity becomes high and the spread becomes worse.
Further, the ratio of the total oil phase component to the hydrophilic silica in the total composition is preferably 500: 1 to 20: 1 by weight because of excellent emulsification stability, use feeling, usability, and makeup sustainability. .
[0019]
The nonionic surfactant of component (C) used in the present invention is HLB 1 to 6, preferably HLB 1 to 4. If the HLB exceeds 6, the emulsion stability will be poor. Here, HLB refers to the hydrophilic / lipophilic balance of the surfactant, is quantified with respect to various nonionic surfactants, and is a value widely used as a guide for selecting an emulsifier.
[0020]
In the present invention, the following general formula for determining the HLB of the nonionic surfactant shown by Griffin, which is particularly useful for polyoxyethylene-based nonionic surfactants, was used.
HLB = E / 5
Here, E shows weight% of the polyoxyethylene part contained in surfactant.
For non-ionic surfactants other than polyoxyethylene,
HLB = 7 + Σ (the number of hydrophilic groups) + Σ (the number of lipophilic groups)
The value obtained from the above was used. Here, the radix is a value unique to the group of the compound and is indicated as the radix of Davis.
[0021]
Such nonionic surfactants are liquid or pasty at 25 ° C. and are particularly preferably insoluble. For example, monoglyceride, sorbitan fatty acid ester, sucrose fatty acid ester, polyglycerin fatty acid ester, alkanolamide, amine Oxide, polyoxyethylene alkyl ether, polyethylene glycol fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene glycerin mono fatty acid ester, polyoxyethylene propylene glycol mono fatty acid ester, polyoxyethylene hydrogenated castor oil, polyoxyethylene fatty acid amide, Polyoxyethylene alkylamine, alkyl saccharide, α-monoalkyl glyceryl ether, dimethylpolysiloxane, polyoxyalkylene Copolymer, dimethylpolysiloxane-monoalkyl glyceryl ether copolymer (Japanese Patent Laid-Open No. 6-135871), and the like.
In particular, α-monoisostearyl glyceryl ether, dimethylpolysiloxane / polyoxyalkylene copolymer, and dimethylpolysiloxane / monoalkylglyceryl ether copolymer are preferable.
[0022]
One or more types of component (C) can be used, and 0.05 to 10% by weight, preferably 0.1 to 5% by weight, is contained in the total composition from the viewpoint of emulsion stability and makeup sustainability. . If it is less than 0.05% by weight, the emulsification stability is poor, and if it exceeds 10% by weight, makeup persistence is deteriorated.
[0023]
The oil agent of component (D) is other than component (A) and is usually used in cosmetics. Examples include hydrocarbons, higher fatty acids, higher fatty acid esters, higher alcohols, animal and vegetable oils, and silicone oils. Can be mentioned. Among these, a liquid oil agent at 25 ° C. is preferable, and silicone oil is particularly preferable from the viewpoint of use feeling.
[0024]
More specifically, examples include dimethylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, octamethylcyclotetrasiloxane, and the like. Furthermore, volatile silicone oil has little stickiness and is refreshing to use and make up. It is preferable in terms of sustainability.
[0025]
One or more types of component (D) can be used, and from the viewpoint of feeling of use, the total composition contains 1 to 50% by weight, preferably 10 to 40% by weight. If it is less than 1% by weight, the feel in use becomes poor, and if it exceeds 50% by weight, the oily feeling becomes strong.
[0026]
The water of component (E) is contained in the total composition in an amount of 20 to 70% by weight, preferably 25 to 50% by weight.
[0027]
In the water-in-oil emulsified cosmetic of the present invention, in addition to the above components, components usually used in cosmetics, such as pigments, water-soluble polymers, inorganic salts, antioxidants, fragrances, dyes, preservatives, UV absorption An agent, a humectant, a refreshing agent, etc. can be contained.
Among these, particularly when pigments are used, the surface is coated with a hydrophobic compound such as a silicone compound, a perfluoroalkyl phosphate compound, a higher fatty acid, or a wax from the viewpoint of makeup sustainability. preferable.
[0028]
The water-in-oil emulsified cosmetic of the present invention can be produced by mixing all the ingredients to be blended at one time, but after uniformly mixing the powder component containing the component (B) with a mixer or the like, Is more uniformly produced by dispersing the component (A), (C) and (D) in the oil phase component, and further adding the component (E) (which may include a water-soluble component) dropwise thereto. Is preferable from the viewpoints of emulsion stability and feel during use.
