Description

[Detailed description of the invention]

In the present invention, particles of a pigment (base pigment) are substantially coated with aluminum N-higher acylglutamate. The particle surface of the base pigment is substantially covered with a film of fibroin (hereinafter referred to as regenerated fibroin) that is regenerated by coagulating the N-higher acyl aluminum glutamate coated pigment and a solution of silk fibroin (hereinafter referred to as fibroin). This invention relates to a cake-like make-up cosmetic composition improved by using a fibroin-coated pigment as a pigment and an oily substance as a binder, and a method for producing the same. In detail, there is no skin irritation, it does not come off on the applicator when used,
Excellent spreadability, adhesion, feel, makeup finish (make-up effect), moisturizing properties, makeup retention, silk-like luster,
It is stable even when continuously used with water-soaked applicators (e.g., wet puffs) or dry applicators (e.g., dry puffs), and can be applied throughout the seasons without causing particle aggregation or hardening phenomena. To provide an excellent cake-like makeup cosmetic that can be smoothly applied and used at any time. Conventionally, cake-like make-up cosmetics (for example, U.S. Patent No.
No. 2034697) (Pancake) uses the water impregnated in the application body and the surfactant in the cosmetic to emulsify and disperse oils and fats before applying it to the skin, so it may cause skin irritation due to the surfactant. It has the disadvantage of causing
In addition, if this cosmetic is used repeatedly with a water-impregnated coating material, the components such as the binder will cause the pigment to adhere and cause a caking (hardening) phenomenon, and will no longer adhere to the dried coating material. I can not use it.
In addition, a cake-like makeup cosmetic that does not contain a surfactant (Japanese Patent Application Laid-open No. 14528/1983) has been proposed, but this cosmetic has a water-repellent silicone oil binding agent that coexists with the pigment. Since it has no affinity with water, it does not mix uniformly, and it is impossible to apply it uniformly or spread smoothly, and it also has the disadvantage that the oils come to the surface with sweat and water, making makeup last longer. Furthermore, even when applied as a dry application, highly hydrophobic (oily) cosmetics give a greasy feel and cannot be used in winter, when the skin is low in moisture, due to skin physiology. The applicant previously
(No. 128707) proposed a cake-like make-up cosmetic that improved the drawbacks of the conventional technology, but as a result of further research, N-higher acyl aluminum glutamate was used instead of the oil-based coating pigment.
When coated pigments are used and an oily substance is blended as a binder, moisture retention, feel during use (moist feel), adhesion (adherence to the skin, layering), and makeup effect (evenness) The present invention was completed based on the discovery that even better effects can be achieved in terms of uniform finish, long-lasting makeup, and cleanliness when reapplying makeup. The purpose of the present invention is to remove the application product, spread on the skin, adhesion (adhesion to the skin, layering, etc.), feel (moist feel, smooth feel, etc.), and make-up without irritating the skin. It has excellent effects (finish of makeup, cleanliness when reapplying makeup, long-lasting makeup, silky shine, etc.), and is stable even when used in wet and dry applications, and can be applied smoothly all year round. The purpose of the present invention is to provide an excellent cake-like makeup cosmetic. That is, in the present invention, an N-higher acyl aluminum glutamate-coated pigment, a fibroin-coated pigment, and an oily substance are uniformly mixed as main constituent components, and the N-higher acyl aluminum glutamate-coated pigment is: The particle surface of the base pigment is substantially coated with aluminum N-higher acylglutamate. The composition is a makeup cosmetic in which the composition is cake-like. The present invention also provides a method of suspending base pigment particles in an aqueous solution containing 0.3 to 10% by weight of N-higher acylglutamic acid monoalkali metal salt based on the weight of the base pigment, and then adding N- 1 to 3 for higher acylglutamic acid monoalkali metal salts
N by gradually adding an aqueous solution containing an equivalent amount of aluminum mineral salt (as anhydride).
-Higher acyl aluminum glutamate is adsorbed onto the particle surface of the base pigment, then deliquified, thoroughly washed with water, and dried to produce an N-higher acyl aluminum glutamate-coated pigment, which is combined with the fibroin-coated pigment. This is a method for producing makeup cosmetics by uniformly mixing oil-based substances. In the N-higher acylglutamic acid aluminum glutamate coated pigment (forming the coating layer) of the present invention, the N-higher acylglutamic acid aluminum has the following general formula: (In the above formula, R is an alkyl group having 11 to 17 carbon atoms, an alkenyl group, or an alkenyl group having a hydroxyl group.) Those represented by the following are preferred. As the N-higher acyl aluminum glutamate-coated pigment, the N-higher acyl aluminum glutamate may be 0.3 to 0.3% based on the weight of the base pigment.
Preferably it is present in an amount of 10% by weight (most preferably 0.3-7%). The N-higher acyl aluminum glutamate-coated pigment as described above is 0.3 to 10% by weight (most preferably 3 to 7% by weight) based on the weight of the base pigment.
After suspending the particles of the base pigment in an aqueous solution containing a monoalkali metal salt (monosodium salt or monopotassium salt) of N-higher acylglutamic acid with a concentration of 0.1 to 10% by weight, the particles are added to this under stirring. When an aqueous solution containing 1 to 3 equivalents of an aluminum mineral salt (aluminum chloride, aluminum sulfate, or aluminum nitrate) at a concentration of 1 to 30% by weight is gradually added to the monoalkali metal N-higher acylglutamic acid salt, both The higher acylglutamic acid aluminum salt produced by the reaction is sequentially oriented and adsorbed onto the particle surface of the base pigment, and after addition, stirring is continued for 10 minutes to effect aging. - Obtained by washing with water until the higher acyl glutamic acid monoalkali metal salt and aluminum mineral salt are removed, and then drying. When the coated pigment obtained in this way was measured for fluorescent X-rays on the surface of the pigment using an X-ray microanalyzer, it was found that
Intrinsic X caused by aluminum atoms near 8.0 Å
When an infrared absorption spectrum was taken using the KBr method, absorption of the amide bond in the N-higher acyl bond was observed at 1650 cm ^-1 , and these results indicated that the coating layer was made of aluminum N-higher acyl glutamate. It is confirmed that The above-mentioned aluminum N-higher acylglutamate coated pigment does not irritate the skin, is water-insoluble, has high lipophilic properties, and absorbs a moderate amount of water, and has good adhesion to the skin, good texture, and It also has good stability over time, so even when combined with the above ingredients, it easily binds to the fibroin-coated pigment via the oily substance, and also provides good feel, cosmetic effect, makeup durability, spreadability, and adhesion. , can impart and exhibit fragrance retention properties. The specificity of its effects is remarkable. The amount of aluminum N-higher acylglutamate coated pigment is usually 10 to 90% by weight (preferably 20 to 80% by weight) based on the total amount of prescription ingredients of the cosmetic. Particularly favorable results can be obtained if an amount of N-higher acyl aluminum glutamate-coated pigment is used in an amount corresponding to 1 to 8% by weight (based on the total amount of formulation components). The maximum particle size of the aluminum N-higher acylglutamate-coated pigment is usually 0.05-60μ, preferably 0.1-30μ. Examples of base pigments in aluminum N-higher acylglutamate-coated pigments and fibroin-coated pigments described below include talc, kaolin, mica, calcium carbonate, titanium dioxide, zinc oxide, titanium mica, magnesium carbonate, iron oxides, and silica. Mention may be made of magnesium acid, nylon powder, polyethylene powder, metal soaps of higher fatty acids, organic pigments or complexes thereof. The fibroin-coated pigment of the present invention is one in which the particle surface of the base pigment is substantially covered with a film of recycled fibroin. Particularly preferred are fibroin-coated pigments in which at least 50% by weight (more preferably 80% by weight or more) of the recycled fibroin is constituted by hot water-insoluble fibroin. In addition, this hot water insoluble fibroin is
Fibroin is a type of fibroin that does not dissolve even when boiled in hot water at 100℃ for 15 minutes. The amount of recycled fibroin film is 2 to 100% by weight, preferably 5 to 100% by weight, based on the base pigment. The crystallinity of regenerated fibroin is usually between 10 and 43.
%, average molecular weight is usually 50,000 to 150,000. The maximum particle size of the fibroin-coated pigment is between 0.05 and 100μ, preferably between 0.05 and 60μ. The blending amount of the fibroin-coated pigment is 10 to 90% by weight, preferably 20 to 80% by weight, based on the total amount of prescription ingredients of the cosmetic.
It is. The above-mentioned fibroin-coated pigment can be obtained by mixing and dispersing the pigment in a 3 to 20% by weight aqueous fibroin solution obtained by dissolving refined silk in a solvent such as a calcium chloride solution or a copper hydroxide-ammonia aqueous solution and then dialyzing it. Fibroin is coagulated and precipitated by adding a specific inorganic salt, followed by dehydration, drying, and pulverization.
-Production method described in Publication No. 11577). The silk fibroin-coated pigment of the present invention has a particle surface of the base pigment with moderate water retention (the water retention amount is usually about 15%).
It has a structure that is substantially covered with a film of regenerated fibroin that has oil absorption (oil absorption is usually about 50 to 60% by weight) and has a water content that is approximately the same as that of the skin. Adhesion, affinity,
It has excellent spreadability, feel, moisture retention, PH buffering properties, covering power, balance between hydrophilicity and lipophilicity, ultraviolet absorption, skin protection, fragrance retention, etc. Therefore, the drawbacks of conventional pigments, namely dehydration from the skin,
There are no problems such as degreasing, dryness, or alkalinization of the skin surface, and the skin can be healthy and protected. Furthermore, since the regenerated fibroin film has a microporous structure as is well known, it has high air permeability and moisture permeability, and can facilitate skin respiration and skin physiology. The oily substance in the present invention is used as a binder for the coated pigment particles, and since both coated pigments have high lipophilicity, selection in formulation design is extremely easy. As the oily substance, oily substances for skin cosmetics are applied, and examples thereof include animal and vegetable oils, waxes, higher aliphatic hydrocarbons, higher fatty acids, higher alcohols, ester oils, silicone oils, polybutenes, and the like. Specifically, for example, liquid paraffin, squalane, petrolatum, microcrystalline wax, polybutene, myristic acid, stearic acid,

The amount of the oily substance blended is within the range of 1 to 30% by weight based on the total amount of prescription ingredients. Further, in the composition of the fibroin-coated pigment and the N-higher acyl aluminum glutamate-coated pigment, at most 15% by weight of the base pigment can be added and blended. The cake-like makeup cosmetics of the present invention are extremely useful as cake-like foundations, eye shadows, blushers, and the like. The present invention provides the above-mentioned fibroin-coated pigment and N-
By appropriately blending high-grade aluminum acylglutamate-coated pigments in the coexistence of oil-based substances, it can be used smoothly and easily in all seasons, does not irritate the skin, has both wet and dry functions, has moisturizing properties, adhesion properties, It has excellent makeup retention, fragrance retention, stability, etc., and gives the skin a good feeling (moisturizing, silky smooth feel), silky, soft natural luster, and luster. A cake-like makeup cosmetic can be easily obtained industrially. The recycled fibroin (film) that makes up the surface of the coexisting fibroin-coated pigment has silky luster, dispersibility, and moderately good water absorption, water retention, and oil absorption (lipophilicity) that are good for the product.
