Description

  The present invention relates to a cosmetic for eyelashes, which is excellent in curling effect, long-lasting effect (long rush effect), deeply eyelash effect (volume effect), and makeup durability including water resistance, and good usability The present invention relates to an oily eyelash cosmetic.

  In recent years, cosmetics for eyelashes generally have a cosmetic effect that makes the eyes stand out by making the eyelashes thicker and longer in addition to the conventional function of curling the eyelashes upward. These eyelash cosmetics are composed mainly of solid oils such as waxes, powders, and film forming agents. In order to realize various usability, feeling of use, and functionality as cosmetics, these components are used. The amount of ingredients is changed. For example, in order to improve the adhesion amount to the eyelashes, a lot of wax or an adhesive oil agent has been added. In addition, fibers have been blended to make the eyelashes thicker and longer. Furthermore, a film-forming resin has been blended in order to improve the curling power of the eyelashes and to enhance makeup sustainability. These conventional eyelash cosmetics mainly consisted of an oil-in-water emulsification type in which wax or a film-forming resin is dispersed in water.

JP 07-267828 A

  However, in the conventional oil-in-water type eyelash cosmetics as described above, the cosmetic effect of making the eyelashes thicker can be obtained by increasing the amount of the wax, but the eyelashes curl upward and make the eyes stand out. The makeup effect is not satisfactory. Further, when the amount of the wax is too large, the system becomes hard, and the drying property and feeling of use may be deteriorated. Furthermore, by increasing the blending amount of the film-forming agent, a cosmetic effect can be obtained that forms a hard film on the eyelashes and curls the eyelashes upward to make the eyes stand out, but the eyelashes are not separated from each other at the time of use. In some cases, it was bundled and the uniformity of the finished product was inferior. And, by blending the fiber, the effect of making the eyelashes look long (long lash effect) can be obtained, but the makeup film may be too hard and fall under the eyes, and the makeup durability is good. And there was a disadvantage that the uniformity of the decorative film was lacking. Furthermore, in oil-in-water type eyelash cosmetics, since wax and film-forming resin are dispersed in water, the system swells when in water and sufficient water resistance cannot be obtained. Had major drawbacks.

JP 2002-154932 A

  Therefore, the objective of this invention is providing the cosmetics for eyelashes which eliminated the fault of such usability, a feeling of use, and makeup sustainability.

  Under such circumstances, the present inventors have conducted various studies, and as a result, an oily eyelash cosmetic containing a specific oil-soluble film-forming resin, a volatile oily component, and powder solves the above problems. The headline and the present invention were completed. The oily eyelash cosmetic in the present invention is a non-emulsifying oily solvent type eyelash cosmetic, which means that the cosmetic is difficult to mix with water.

  That is, (A) a hydrogenated styrene / methylstyrene / indene copolymer, (B) trimethylsiloxysilicic acid, (C) a volatile oily component, and (D) a cosmetic for oily eyelashes containing powder. If it is applied, it dries quickly when applied to the eyelashes, does not bleed into the lower eyelid over time, and has a good feeling of use. It has been found that a visible oily eyelash cosmetic can be provided.

  The oily eyelash cosmetic of the present invention has no problem in terms of functionality by blending a hydrogenated styrene / methylstyrene / indene copolymer, trimethylsiloxysilicic acid, a volatile oily component, and powder, and the eyelashes By applying to the surface, there is an advantage that excellent water resistance and cosmetic effect can be exhibited.

  The present invention provides an oily eyelash makeup comprising (A) a hydrogenated styrene / methylstyrene / indene copolymer, (B) trimethylsiloxysilicic acid, (C) a volatile oily component, and (D) a powder as constituent components. It is a fee.

  The hydrogenated styrene / methylstyrene / indene copolymer, which is the component (A) of the present invention, is a hydrogenated styrene / methylstyrene / indene copolymer, and is represented by the following general formula (1).

  The softening point of the component (A) of the present invention is preferably 95 ° C. or higher and 105 ° C. or lower.

  Component (A) preferably used in the present invention is Alcon P-100 (manufactured by Arakawa Chemical Industries) as a commercial product.

  In the oily eyelash cosmetic of the present invention, the component (A) is preferably blended in an amount of 11 to 25% by weight, more preferably 15 to 20% by weight based on the total amount of the oil. If it is less than 11% by weight, the lower eyelid bleeds over time, and the effect of maintaining makeup is low. If it is more than 11% by weight and 15% by weight or less, the effect of preventing bleeding can be exhibited, but the effect of curling force is slightly low. If it is more than 20% by weight and not more than 25% by weight, a sufficient effect can be expected in terms of makeup sustainability, but some dissatisfaction remains in usability. If it is 25% by weight or more, it tends to be difficult to use such as poor drying when applied to eyelashes.

  The component (B) of the present invention, trimethylsiloxysilicic acid, is a compound having a cross-linked structure having a siloxane structure as the main skeleton, and is represented by the following general formula (2). KF-7312J, KF-7312K, KF-9021 (all manufactured by Shin-Etsu Chemical Co., Ltd.) and the like can be used.

  The component (B) particularly preferably used in the present invention is a commercially available product, KF-9021 (manufactured by Shin-Etsu Chemical Co., Ltd., diluted with decamethylcyclopentasiloxane of trimethylsiloxysilicic acid, containing about 50% as trimethylsiloxysilicic acid) There is.

  In the oily eyelash cosmetic of the present invention, 1 to 7% by weight of trimethylsiloxysilicic acid is preferably blended with respect to the total amount of the cosmetic, and more preferably 3 to 5% by weight with respect to the total amount of oil. If the amount is less than 1% by weight, the lower eyelid bleeds over time and the makeup lasting effect is low. If it is more than 1% by weight and not more than 3% by weight, the effect of preventing bleeding can be exhibited, but the effect of curling force is slightly low. If it is more than 5% by weight and not more than 7% by weight, a sufficient effect can be expected with regard to makeup sustainability, but some dissatisfaction remains in usability. If it is 7% by weight or more, it tends to be difficult to use such as poor drying when applied to eyelashes.

  The volatile oil agent which is the constituent component (C) of the present invention is a component which improves usability as a solvent for the components (A) and (B), and is a volatile oil agent which is not mixed with water usually used in cosmetics. This does not include alcohol. Specific examples include volatile silicones such as low-boiling isoparaffinic hydrocarbons having a boiling point of 260 ° C. or lower at normal pressure, low polymerization degree dimethylpolysiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and the like. It can be blended as needed or in combination of two or more. Examples of such low-boiling isoparaffinic hydrocarbons include IP solvents 1620 and 2028 (manufactured by Idemitsu Petrochemical Co., Ltd.) and shell sol (manufactured by Shell Chemical Co., Ltd.).

  In this invention, although the quantity of a component (C) is not specifically limited, 30 to 60 weight% is preferable with respect to cosmetics whole quantity, More preferably, 35 to 50 weight% is good. The reason is that if it is 60% by weight or more, it is difficult to exert a sufficient effect in the drying effect when the eyelash cosmetic is applied, and if it is more than 50% by weight and less than 60% by weight, the effect in the drying effect at the time of application can be exhibited. The effect is somewhat low under severe conditions such as when using a foundation with a lot of oil components or when applying under conditions of high temperature and humidity. If it is 30% by weight or more and less than 35% by weight, a sufficient effect can be expected with regard to makeup sustainability, but some dissatisfaction remains in usability. When it is blended in an amount of less than 30% by weight, it tends to be difficult to use, such as poor adhesion to cosmetic tools and difficult to apply to eyelashes.

  As the oil component used in the present invention, in addition to the essential component (C) volatile oil, solid oil, semi-solid oil, liquid oil and the like generally used for cosmetics can be used. Regardless of animal oil, vegetable oil, mineral oil or synthetic oil, oils and fats, waxes, hydrocarbons, fatty acids, higher alcohols, alkyl glyceryl ethers, esters, silicone oils, fluorine oils, lipophilic interfaces Examples include activators. Specifically, oils such as olive oil, coconut oil, avocado oil, castor oil, safflower oil, hydrogenated oil, mink oil, horse oil; lanolin, whale wax, beeswax, carnauba wax, jojoba oil, candelilla wax, etc. Waxes; liquid paraffin, paraffin, microcrystalline wax, petrolatum, isoparaffins, ceresin, polyethylene, polybutene, squalene, squalane, and other hydrocarbons; lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, behenic acid Fatty acids such as oleic acid and isostearic acid; higher alcohols such as isostearyl alcohol, octyldodecanol, oleyl alcohol, and hexyldodecanol; alkyl glyceryl ethers such as batyl alcohol, chimyl alcohol, and ceralkyl alcohol; olein Ethyl, isopropyl myristate, isopropyl palmitate, cetyl palmitate, myristyl myristate, octyldodecyl oleate, isopropyl isostearate, ethyl isostearate, cetyl 2-ethylhexanoate, stearyl 2-ethylhexanoate, isocetyl isostearate, dimethyl Esters such as octyldodecyl octanoate, myristyl lactate, diisostearyl malate, glyceryl tri (capryl / caprate) glyceryl; silicones such as dimethylpolysiloxane, methylphenylpolysiloxane, cross-linked organopolysiloxane; Fluoro oils such as fluoropolyether, perfluorodecane, and fluorine-modified silicone; lipophilic interfaces such as glycerin monostearate and sorbitan monostearate Sex agents and the like, can be used more than those one or two.

  The powder which is the constituent component (D) of the present invention includes pigments commonly used in cosmetics, for example, inorganic powders such as talc, sericite, mica, kaolin, anhydrous silicic acid, calcium carbonate, magnesium carbonate, clay mineral and the like. Organic powder such as hemp cellulose powder, silk powder and corn starch; metal soap such as aluminum stearate, zinc stearate and magnesium myristate; synthetic polymer powder such as nylon powder, polyethylene powder and crystalline cellulose; legal dye; Natural pigments such as squid powder, turmeric extract, caramel, gardenia yellow, safflower red, shikonin; inorganic pigments such as carbon black, titanium oxide, iron oxide, ultramarine, and bitumen; titanium oxide coated mica, iron oxide coated mica, titanium oxide coated Examples include pearl pigments such as synthetic phlogopite. These are used alone or in combination.

  In the present invention, the amount of the component (D) is not particularly limited, but is preferably 15 to 30% by weight, more preferably 20 to 25% by weight based on the total amount of the cosmetic. The reason is that if it is less than 15% by weight, it is difficult to exert a sufficient effect in the effect of drying when applied, and if it is 15% by weight or more and less than 20% by weight, the effect of drying and the effect of making it thick can be exhibited. Under severe conditions such as high and high humidity, the effect is slightly low. If it is more than 25% by weight and not more than 30% by weight, a satisfactory effect can be expected with respect to the effect of holding and drying the makeup, but some dissatisfaction remains in usability. When it is added in an amount of more than 30% by weight, it tends to be difficult to use because it does not adhere to the cosmetic tool or cannot be applied to the eyelashes.

  In the present invention, the component (D) can be used after surface treatment with a known surface treatment agent such as a fluorine compound, a silicone compound, or a surfactant, if necessary. Among these surface-treated powders, it is preferable to use a powder that has been surface-treated with a fluorine compound, because it gives a lustrous impression when applied to eyelashes, and the effect of making the eyes stand out better. As the fluorine compound for surface-treating the powder used in the present invention, any fluorine compound that is a generally known treating agent can be used. Specific examples include perfluoroalkyl group-containing esters, perfluoroalkylsilanes, perfluoropolyethers, polymers having a perfluoroalkyl group, and the like.

  In the present invention, the amount of the powder surface-treated with the fluorine compound is not particularly limited, but it is preferably 35 to 80% by weight, more preferably 55 to 65% by weight in the component (D). Is good. The reason is that if it is less than 35% by weight, it is difficult to exert a sufficient effect on the effect of drying and the effect of showing glossy, and if it is 35% by weight or more and less than 55% by weight, the effect of drying and the effect of showing glossy can be exhibited, The effect is somewhat low under severe conditions such as high temperature and high humidity. If it is more than 65% by weight and not more than 80% by weight, a satisfactory effect can be expected with respect to the effect of holding and drying the makeup, but there is still some dissatisfaction with usability. If it is added in an amount of more than 80% by weight, it tends to be difficult to use such as poor adhesion to cosmetic tools and inability to apply to eyelashes.

  In addition to the components (A) to (D) of the present invention, the cosmetic for oily eyelashes of the present invention further increases the drying speed of the cosmetics, and advances the cosmetics ahead of the eyelashes. It is preferable to add ethanol in order to increase the effect of sticking and making the eyelashes look longer.

  In the present invention, the amount of ethanol to be blended is preferably 2 to 6% by weight. If the amount is less than 2% by weight, the effect of further speeding up drying is small, and if the amount is more than 6% by weight, the above-mentioned two effects cannot be expected to be enhanced.

  Furthermore, the oily eyelash cosmetic of the present invention is not particularly limited as long as it is used as an ordinary cosmetic raw material. For example, surfactants not containing lipophilic surfactants, animal and plant extracts, amino acids and peptides , Vitamins, antioxidants, sequestering agents, bactericides / preservatives, ultraviolet absorbers, pH adjusters, and the like can be blended within a range in which the effects of the present invention are not impaired.

  Hereinafter, although an example is given and it explains in detail, the present invention is not limited to these.

  The oily eyelash cosmetics of Formulation Examples 1 to 27 and Comparative Examples 1 to 4 having the compositions shown in Tables 1 to 3 were prepared. In addition, the unit of the numerical value in a table | surface is weight%.
