Description

The present invention relates to an oily liquid cosmetic composition, and more specifically, it firmly adheres to the skin by contact with water, sweat, etc. and maintains the ultraviolet protection effect, and also cleans general soap and body soap with a low cleansing effect. The present invention relates to an oily liquid cosmetic having an unprecedented characteristic that it can be easily washed off even with an agent.

In recent years, the importance of compositions for protection from UV rays has increased. Protecting the skin from ultraviolet rays is an important issue, and cosmetics having various sunscreen effects have been developed. The sunscreen cosmetic has a function of protecting the skin from ultraviolet rays by blending an ultraviolet absorber or an ultraviolet scattering agent to block the arrival of ultraviolet rays on the skin.

As the cosmetics having a sunscreen effect, there are commercially available cosmetics such as creams or liquids which are applied to the skin by hand and sprays which are directly sprayed on the skin.
It is natural that these products are required to have a long-lasting anti-UV effect and a good feeling of use, but in addition to these, in the case of aerosol type sunscreen cosmetics, the compatibility with the propellant is good, Usability is also required so that the contents can be easily and evenly mixed with a little shaking.

It is generally known that when a sunscreen cosmetic applied to the skin comes into contact with water or sweat, an ultraviolet absorber or an ultraviolet scatterer flows out from the applied cosmetic, which lowers the ultraviolet protective effect.
In order to prevent this, for example, attempts have been made to add a large amount of resin or oily film forming agent for imparting water resistance to cosmetics, but completely prevent the outflow of ultraviolet absorbers and ultraviolet scattering agents. Hard to do.
In fact, there are products in the market that prevent the outflow of sweat and water by blending a large amount of an oily film-forming agent such as trimethylsiloxysilicic acid into the outflow of an ultraviolet absorber or the like. In the case of such products, it is not possible to wash them off with general detergents such as soap and body soap, and it is necessary to use special oil cleansing or the like in order to wash them off cleanly.

In Patent Document 1, by incorporating an ultraviolet absorber, an organically modified clay mineral, an oil phase thickener, a silicone surfactant having an HLB of less than 8, a spherical resin powder, and a volatile silicone oil, water and A sunscreen cosmetic has been disclosed in which the ultraviolet protection effect does not decrease even when contacted with sweat or the like.
Since it is emulsified in a water-in-oil type, it is preferable that it has high water resistance, but it has high water repellency and adhesiveness, and cannot be sufficiently washed off with a general body soap or other cleaning agent.
In addition, because it contains an oil phase thickener and organic modified clay minerals for stabilization, it has a strong oil film feeling immediately after application, causing a problem in use that it becomes oily or sticky to use. is there.

In Patent Document 2, the dispersibility of powder is improved by dispersing an inorganic oxide powder such as a UV scattering agent in an oily liquid containing a specific lipophilic solvent (ester oil), alcohol and a UV absorber. An aerosol-type sunscreen cosmetic using the non-aqueous stock solution thus prepared is described.
Since the dispersibility of the powder is improved, it is difficult for the powder to settle in a short time, and it is possible to jet with a uniform composition. Although it is a composition that does not easily clog even after repeated use, the UV-scattering agent is merely uniformly dispersed in the oily base material, so the oil-soluble UV-absorbing agent flows out when it comes into contact with water or sweat. However, it is not possible to prevent the deterioration of the UV protection effect. Further, since it is a non-aqueous composition, the washability is not good.
Thus, up to now, no sunscreen composition has been known which has sufficient water resistance and can be easily removed with a detergent such as general soap or body soap.

In addition, it is an innovative oil-based liquid cosmetic having properties contrary to the conventional wisdom that it can be easily washed off with general detergents such as soap and body soap.

As described above, the oily liquid cosmetic composition of the present invention is characterized by containing (A) an ultraviolet protective agent and (B) a specific polyether-modified silicone (C) a volatile oil agent.

The oily liquid cosmetic composition of the present invention has a fluid state at room temperature (25° C.). When the viscosity is high and the fluidity is unknown, it can be determined by using the ASTM D4359-90 test described in "Global Harmonization System for Classification and Labeling of Chemicals (GHS)".

Each essential component of the present invention will be described in detail below.
<Component (A): UV protection agent>
The component (A) blended in the present invention can be selected from those blended in ordinary cosmetics, and is appropriately selected from a UV absorber and a UV scatterer.
The ultraviolet absorber is not particularly limited, but specific examples thereof include ethylhexyl methoxycinnamate, octocrylene, t-butylmethoxydibenzoylmethane, ethylhexyltriazone, hexyl diethylaminohydroxybenzoylbenzoate, oxybenzone-3, methylenebisbenzotriazolyl. Examples thereof include rutetramethylbutylphenol, phenylbenzimidazole sulfonic acid, homosalate, and ethylhexyl salicylate.

The ultraviolet scattering agent is not particularly limited, but as a specific example, fine particle metal oxide can be used. Examples thereof include titanium oxide, zinc oxide, zirconium oxide, cerium oxide and the like. The surface of these metal oxides may be coated with an inorganic compound such as silica or alumina, or an organic compound such as fatty acid metal soap or silicone.
The fine particle metal oxide has a so-called fine particle diameter and, for example, has a primary particle diameter of usually 100 nm or less as observed by an electron microscope. The fine particle metal oxide used in the present invention is selected from the group consisting of fine particle titanium oxide and fine particle zinc oxide because it has an excellent ultraviolet scattering effect. Particulate titanium oxide is more preferred.

The ultraviolet protective agent used in the present invention is not particularly limited, and only one of the ultraviolet absorbent and the ultraviolet scattering agent may be used, or they may be used in combination. The type is not limited, but for example, when it is desired to exert an excellent UV protection effect in a wide wavelength range from UVA to UVB, a UV absorber having an absorption peak in the UVA region (UVA absorber) and UVB It is preferable that at least one type of ultraviolet absorber having an absorption peak in a region (UVB absorber) is combined in combination, or at least one type of ultraviolet absorber having a broad absorption band extending from UVA to UVB region is blended. It is also effective and preferable to use an ultraviolet scattering agent and an ultraviolet absorbing agent together.

The blending amount of the component (A) varies depending on the desired anti-UV effect, but is, for example, 3% by mass or more in the cosmetic, more preferably 5 to 40% by mass, and further preferably 7 to 30% by mass. Within this range, a certain ultraviolet ray prevention effect can be expected.
In addition, when the obtained cosmetic is used as an undiluted solution and is made into an aerosol type, it may be considered that the blending amount is a ratio in the undiluted solution. The same applies to the following components.

<Component (B): Decamethylcyclopentasiloxane: Polyether-modified silicone: Polyether-modified silicone having the property of gelling when mixed with water=90:10:2>
The component (B) blended in the present invention is selected to have a property of gelling when mixed in a mass ratio of decamethylcyclopentasiloxane:polyether-modified silicone:water=90:10:2. The polyether-modified silicone having such properties has a characteristic that it is thickened by water, and further, when a certain amount of water or more enters, it rapidly gels and loses fluidity. A gelled product formed by contacting a small amount of water with a modified silicone has high water resistance and high adhesion to the skin.In the present invention, this property is not exhibited by the cosmetic itself, but after application of the cosmetic. , Applied to make a coating film that is water-resistant and has high adhesion to the skin when the cosmetic comes in contact with a small amount of water such as sweat. The present invention has been completed by finding that it has an affinity for most detergents and that even detergents such as general soap and body soap have good detergency.

There is no particular limitation as long as it is a polyether-modified silicone that is determined to have the property of gelling by this determination method. For example, hydrophilic groups represented by the following formulas are polyoxyethylene (PEG) and polyoxypropylene (PPG). And a side chain type high molecular weight polyether modified silicone.

When m is less than 50 and n is less than 1, gelling cannot be achieved due to poor affinity with water. When m exceeds 1,000 and n exceeds 40, a strong sticky feeling is produced. Further, m:n is preferably 200:1 to 5:1, a is preferably 5 to 50, and b is preferably 5 to 50. Although not particularly limited, the molecular weight of the polyether-modified silicone used in the present invention is such that the gelled product is compatible with the soap component in the detergent while forming a strong water resistant film when gelled with water. It is desirable that the polymer has a molecular weight of 10,000 or more in order to have the property of being easily washed off.

The polyether-modified silicone that can be used in the present invention may be commercially available, for example, trade name BY11-030 (manufactured by Toray Dow Corning Silicone Co., Ltd.: 50% by mass of PEG/PPG-19/19 dimethicone and 50% by mass). Cyclopentasiloxane: HLB=3.5). The trade name BY25-337 (manufactured by Toray Dow Corning Silicone Co., Ltd.: 50% by mass of PEG/PPG-19/19 dimethicone and 50% by mass of light liquid isoparaffin) is exemplified.
(The above-mentioned PEG/PPG-19/19 dimethicone is a polyether-modified silicone having m=400, n=10, a=19, b=19 and a molecular weight of 55,000 in the above general formula)

The blending amount of the component (B) in the present invention is, for example, 5 to 25% by mass, preferably 7 to 20% by mass, and more preferably 9 to 15% by mass in the cosmetic, so that sufficient water resistance can be applied. It is possible to combine the function of easily washing off the film with a cleaning agent such as general soap or body soap.

<Component (C): volatile oil agent>
The component (C) to be blended in the present invention is not particularly limited as long as it is a liquid oil which is volatile at room temperature (25° C.) and atmospheric pressure (1 atm) which has been conventionally used for cosmetics and the like. Specific examples include volatile hydrocarbon oils and volatile silicone oils. By blending the volatile oil agent, the cosmetic material can be made excellent in lightness of spreadability and no oily film feeling.
Examples of the volatile hydrocarbon oil include isododecane, (C13,14)isoparaffin, hydrogenated polyisobutene, and the like.
Examples of the volatile silicone oil include volatile linear and branched silicone oils (volatile dimethicone) and cyclic silicone oils. Specifically, low-viscosity dimethylpolysiloxane such as decamethyltetrasiloxane can be used as the chain silicone, and methyltrimethicone can be used as the chain silicone, and octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, etc. can be used as the cyclic silicone.

The blending amount of the component (C) in the present invention is not particularly limited, but is preferably 20 to 70% by mass, preferably 25 to 65% by mass, more preferably 30 to 60% by mass. When blended in this range, it is possible to obtain a light-spreading cosmetic composition with less oily film feeling.

<Component (D): powder other than component (A)>
The component (D) blended in the present invention is not particularly limited and can be selected from known powders according to the purpose. By blending a powder other than the component (A), it is possible to improve the feeling of use and obtain a smooth and good feel.
Examples of the inorganic powder include plate powders such as talc, mica, sericite, and boron nitride, spherical powders such as spherical silica and spherical porous silica, and those whose surfaces are subjected to a hydrophobic treatment.
Examples of the organic powder include amorphous particle powder such as PTFE, plate-like powder such as lauroyl lysine, polyacrylic acid ester and its copolymer, polyurethane, polyamide, silicone powder and the like, which are spherical or porous. And so on.
Among these, spherical powders of polymethylmethacrylate crosspolymer, nylon, silica, polymethylsilsesquioxane, etc. are smooth and have a reduced stickiness and a dry feel. Further, when a spherical porous PMMA powder or silica is blended, it has a good feeling of use with a continuous dry feeling and can be preferably used.
Further, it is preferable to select an organic powder having a small specific gravity because the redispersibility is improved.

The content of the component (D) in the present invention is not particularly limited, but it is preferably 0.1 to 30% by mass, more preferably 2 to 20% by mass, further preferably 3 to 15% by mass in the cosmetic. .. Within this range, whitening is less likely to occur after application and a good feeling during use can be maintained for a long time.

The term "substantially free of water" as referred to in the present invention means that the blending of water itself, plant extracts containing water, raw materials containing water, etc. is allowed as long as the present invention does not cause any inconvenience. It means that.
In other words, the present invention is a low-viscosity oily liquid cosmetic that originally does not need to contain water, but when adding water for the convenience of adding a moisturizer such as a plant extract, the viscosity is increased. However, there is no problem as long as the water content can maintain a liquid state and fluidity. Therefore, making a so-called non-aqueous system is not an essential condition.

In the present invention, as described above, the component (B) has the characteristic of "thickening with water, and when a certain amount or more of water enters, it rapidly gels, and the resulting gelled product has water resistance." Utilizes features. At this time, even if the cosmetic gels and solidifies, the UV protection effect does not decrease even after contact with water, sweat, etc., and it can be easily washed off with general detergents such as soap and body soap. There is no impact on the main effects of. However, when solidified, the elongation becomes very heavy, the usability is deteriorated, and it becomes difficult to apply the composition uniformly, which may cause problems in use. Furthermore, if the undiluted solution of the aerosol composition is solidified, when it is mixed with the propellant, it cannot be made uniform during the filling step, and the productivity is reduced. If the undiluted solution does not dissolve in the propellant, caking will occur and it will not be possible to re-disperse it, or the injection pattern will deteriorate.Therefore, depending on the dosage form, when you want to use it in liquid form or with an aerosol type makeup When it is desired to use as a cosmetic, it is preferable to avoid solidification of the cosmetic or the cosmetic used as an undiluted solution of the aerosol type cosmetic. In this case, the amount of water that does not solidify differs mainly depending on the types and blending amounts of the polyether-modified silicone and the liquid oil. For example, by adjusting the amount of water in the range of 3.0% by mass or less, the cosmetic fluid flows. Can be kept in a sexual state.

The oily liquid cosmetic of the present invention can also be provided as an aerosol-type cosmetic that is used by filling and spraying an aerosol container.
The aerosol container is filled with the cosmetic of the present invention as a stock solution, and the stock solution is filled together with a propellant.

The propellant is not particularly limited and can be selected from known propellants according to the purpose. Examples thereof include LPG (liquefied petroleum gas), DME (dimethyl ether), carbon dioxide, nitrogen, nitrous oxide, and fluorohydrocarbon. Among these, LPG and DME which are liquefied gases can be preferably used.

The blending amount of the propellant for producing the aerosol-type cosmetics is preferably 1.5 to 9 times that of the undiluted solution when using liquefied gas, for example. It is more preferably 2 to 8 times. More preferably, it is 3 to 7 times. Within this range, a sufficient ejection force can be obtained and uniform spraying can be achieved. Further, the undiluted solution is diluted with the propellant to have a low viscosity and the spray particles are small and uniform, so that the feeling of oil film during use can be reduced. The cosmetics of the present invention can be applied not only to sunscreen cosmetics but also to makeup cosmetics such as foundations having a sunscreen effect and makeup bases.

In the oily liquid cosmetic of the present invention, in addition to the essential components, a non-volatile oily agent may be added as long as the effect of the present invention is not impaired. The non-volatile oil agent of the present invention is an oil agent that does not exhibit volatility at normal temperature (25°C) and normal pressure (1 atm). For example, liquid oils and fats such as hydrocarbon oils and vegetable oils, oils such as ester oils and silicone oils are included.
Specific examples thereof include animal and vegetable oils such as avocado oil, macadamia nut oil, mink oil, olive oil and candelilla wax; isononyl isononanoate, isodecyl isononanoate, isotridecyl isononanoate, isostearyl myristate, isopropyl myristate, 2-ethylhexanoate. Ester oils such as cetyl, octyldodecyl myristate, and glycerin tristearate; hydrocarbon oils such as squalane, liquid paraffin, hydrogenated polyisobutene, paraffin, α-olefin oligomer, white petrolatum, and ceresin: dimethicone, diphenylsiloxyphenyltrimethicone, etc. Silicone oil of.

In the oily liquid cosmetic of the present invention, in addition to the essential components, an oily film forming agent can be blended as long as it does not impair the washability. By blending the oil film-forming agent, the resistance to the outflow of the ultraviolet absorbent and the abrasion of the ultraviolet absorbent can be further increased.

The oily film forming agent is not particularly limited as long as it is usually used in cosmetics, and specifically, such as PVP/eicosene copolymer, PVP/hexadecene copolymer, PVP/VA copolymer. PVP-based coating agents, acrylic acid-based coating agents such as ethyl acrylate/acrylic acid amide/acrylic acid copolymers, ethyl acrylate/butyl acrylate copolymers, trimethylsiloxysilicic acid, polymethylsilsesquioxanic acid, etc. And the like silicone-based coating agents. Among these, trimethylsiloxysilicic acid is preferable from the viewpoint of water resistance and oil resistance.

In the oily liquid cosmetic of the present invention, in addition to the essential components, components that are usually used in cosmetics, such as a whitening agent, a moisturizing agent, an antioxidant, a sequestering agent, in a range that does not impair the effects of the present invention, A surfactant, an alcohol, a colorant, an aqueous activator, etc. may be appropriately added according to need, and the mixture can be produced by a conventional method.

Hereinafter, the present invention will be described in more detail with reference to specific examples, but the present invention is not limited to the following examples. In addition, the compounding amount in the following examples and the like indicates mass% unless otherwise specified.

<Evaluation method of gelation of polyether-modified silicone>
The polyether-modified silicone (component B) is selected by evaluating whether it has the property of gelling when mixed in a mass ratio of decamethylcyclopentasiloxane:polyether-modified silicone:water=90:10:2.
The polyether-modified silicone is dissolved and dispersed in decamethylcyclopentasiloxane at a predetermined ratio, water is added and the mixture is stirred.
Regarding the presence or absence of gelation, when the viscosity of the mixture obtained by the above method was measured using a B type viscometer, it was 10,000 mPa.s at 25°C. When it was s or more, it was determined that the gelling property was exhibited. (Measuring device: B-type viscometer TVB-10M manufactured by Toki Sangyo Co., Ltd.)

Low molecular weight side chain polyether modified PEG-10 dimethicone, high molecular weight side chain polyether alkyl modified cetyl PEG/PPG-10/1 dimethicone, high molecular weight linear block copolymer type polysilicone In the case of -13, the viscosity is 10,000 mPa.s even when water is added to a predetermined mixture with decamethylcyclopentasiloxane. Nothing reached s, and no gelation was observed.
However, gelation was observed only by mixing water with PEG/PPG-19/19 dimethicone, which is a polymer side chain type polyether-modified silicone. It is guessed that the polyether modification is a side chain type like the molecular structure of [Chemical formula 1] and it is a polymer, so that 9 times amount of decamethylcyclopentasiloxane is added by adding a small amount of water. It is thought that it became possible to gel.

An oily liquid cosmetic having the composition shown in Table 2 below was prepared by adding powder to a solution obtained by heating and dissolving an oily component and stirring the mixture. Evaluation items 1 and 2 were evaluated for the obtained undiluted solution of each example.
Further, for evaluation items 3 to 6 and 8, 6 g of the stock solution and 24 g of LPG (0.15 MPa) were filled in a 100 ml aerosol test bottle (manufactured by Tokyo Polymer Co., Ltd.: a transparent glass test bottle with a soft PVC film) (bulk: Propellant = 1:4) Used as a test sample.
All% in Table 2 are% by mass.

Evaluation items 1 and 2
1: (Measurement of initial UV protection effect) A predetermined PMMA plate HELIOPLATE HD6 (5×5 cm surface roughness 6 μm manufactured by HELIOSCREEN) was dripped with the cosmetics (stock solution) of each example in an amount of 2 mg/cm2, and a finger was applied for 60 seconds. After coating for 15 minutes and drying for 15 minutes, measurement was performed with an SPF analyzer (UV TRANSMITTANCE ANALYZER/UV-1000S manufactured by LABSPHERE). The PMMA plate coated with the sample was measured at 10 points, and the average value was used as the SPF value of the sample.
2: (Water bath test/change in UV protection effect) The measured plate was sufficiently immersed in water at 20°C, and then immersed in water in a 20°C incubator for 30 minutes as it was. After that, the surface was dried for about 15 to 30 minutes until water drops disappeared, the SPF value was measured again in the same manner, and the change suppression rate (the following formula) was calculated from the SPF value before and after the water bath as a change in the ultraviolet protection effect.
3: (Criteria for judging change in UV protection effect) In the present invention, it was judged that the UV protection effect was sufficiently maintained when the SPF value change suppression rate exceeded 95%.

(Equation 1) SPF value change suppression rate (%)=(SPF value after water bath)/(SPF value before water bath)×100

Evaluation items 7, 8, 9 Redispersibility of aerosol composition (evaluated after 1 month)
Each aerosol test bottle is filled with three samples, stored at room temperature and 40° C. in a freezer for one month, returned to room temperature, and then inverted upside down 10 times, and then evaluated.
Good: All conditions were uniformly dispersed, and uniform and fine particles could be sprayed. Poor: Caking occurred under each condition (Caking: Sedimentary lower layer has poor dispersibility and does not disperse evenly on the bottom. Status)

Examples 1 to 8: The SPF value was sufficiently maintained even after the water bath test, and the soap-based body soap could be easily washed off. Furthermore, the redispersibility of the aerosol composition was good even after 1 month under each condition (room temperature, 40° C., freezer). Example 8 was slightly inferior in the feeling of use because no powder was blended, but the main problem of the present application was solved.
Comparative Examples 1 and 2: Samples in which the polyether-modified silicones *2 and *3 that did not gel in <Evaluation method of gelation of polyether-modified silicone> were blended, the SPF value obviously decreased after the water bath test. Furthermore, the evaluation of the detergency with soap-based body soap was low.
Comparative Example 3: Since the compounding amount of trimethylsiloxysilicic acid which is an oily film forming agent was large, the SPF value could be maintained even after the water bath test. However, it could not be washed with soap-based body soap, and it was necessary to remove it with a separate cleansing oil.
Comparative Example 4: In the aerosol test bottle, since the stock solution had a large amount of water and gelled, the gelled stock solution was not dissolved by the propellant when the LPG as the propellant was filled. Therefore, it was shaken well and mixed, but it became dispersed with large particles, and I felt a strong stickiness. It had a great elongation and a strong filmy feeling. Further, when the aerosol composition was used, the redispersibility after one month caused caking under all three conditions (room temperature, 40° C., freezer).
Comparative Example 5: Since the volatile oil agent was replaced with a non-volatile oil agent, an oily film feeling and stickiness were felt for a long time. The SPF value immediately after coating was high, but the SPF value after the water bath test was low. Furthermore, the affinity of the coating film for detergents was impeded by the non-volatile oil agent, and the detergency was lowered.
