Description

[Detailed description of the invention] The present invention relates to a novel cosmetic.

Cosmetics are generally made by blending cosmetic oils with appropriate additives.
Water-based type emulsified with emulsifier, pigment and cosmetic oil,
It is classified as a solid type that is kneaded with additives.

The most commonly used cosmetic oils are castor oil, wood wax, lanolin, beeswax, squalane, olive oil, jojoba oil, and other animal and vegetable oils.
There are synthetic oils such as isopropyl myristate, octyldodecyl myristate, octanoic acid/decanoic acid mixed glyceride, isooctanoic acid glyceride, silicone oil, and mineral oils such as ceresin and liquid paraffin. However, since these are oil-based, they have poor oxidation stability and
In addition, conventionally used emulsifiers are not always satisfactory in terms of safety, skin feel, emulsion stability, etc., and therefore have various difficulties in the production of cosmetics.

An object of the present invention is to provide a cosmetic that does not have the above-mentioned drawbacks during production.

As a result of intensive research by the present inventors, 1. The above purpose is achieved by using protein or partially hydrolyzed protein obtained by hydrolyzing it with a proteolytic enzyme as an emulsifier, emulsifying and dispersing cosmetic oils and additives therein, and then spray-drying. I found out that it can be done.

The present invention was completed based on this knowledge, and uses an aqueous solution of protein or partially hydrolyzed protein obtained by hydrolyzing it with a protein autolytic enzyme as an aqueous phase, and uses a cosmetic oil, an antioxidant, and a vitamin preparation. , obtained by spray drying an oil-in-water emulsion containing additives such as hormones, drugs, preservatives and antibacterial agents, and fragrances as the oil phase.The outer shell is protein and the interior contains oil and additives. This is a cosmetic containing powder.

Examples of the protein used in the present invention include vegetable proteins obtained from soybeans, sunflowers, etc., and animal proteins such as gelatin and casein.

Partially hydrolyzed proteins obtained by hydrolyzing the above-mentioned proteins with protein hydrolytic enzymes can also be used. Partially hydrolyzed protein is obtained by partially hydrolyzing protein obtained by conventional methods with an acid such as hydrochloric acid or a protein hydrolytic enzyme such as pepsin or papain.

Casein and celadin themselves have a heavy feel, and emulsions made of them exhibit high viscosity, and in order to spray dry them, it is necessary to increase the water content to about 70 to 90% and lower the viscosity. For this reason, the energy cost during spray drying increases, but casein and gelatin are preferable for cosmetics that are heavy to the touch and have a filmy feel. Generally, soybean protein is a good protein in terms of raw material, color, odor, texture, etc. Furthermore, from the viewpoint of emulsifying properties, dispersibility, feel as a cosmetic, etc., it is preferable to use partially hydrolyzed extracted soy protein, concentrated soy protein, and isolated soy protein obtained by conventional methods.

In the case of hydrochloric acid, the conditions for partial hydrolysis are to use a 1 to 5% phlegm dispersion solution, maintain the chlorine concentration at 0.3 to 3%, and the decomposition temperature in the range of 75 to 95°C for about 1 to 50 hours. It is. In addition, in the case of protein hydrolytic enzyme, a 1 to 5% protein solution is used, and the enzyme amount is 0.03 to 0.3% based on the solid content.
and keep at the optimum pH and temperature for the enzyme for 1 to 50 hours.

The degree of partial hydrolysis is indicated by the solubility of the protein in a 20% trichloroacetic acid aqueous solution (hereinafter referred to as TCA solubility), and in the present invention, it is preferable that the TCA solubility is 10 to 60% by weight. When the TCA solubility is 60% or more,
The emulsifying property is reduced and the inclusion function is also reduced.

Partially hydrolyzed soy protein has a large emulsifying power, and it is possible to emulsify water and oil with a small amount of partially hydrolyzed soy protein. In other words, when partially hydrolyzed soybean protein is used, the oil content is approximately 90 to 92% (coating material: oil -1:
9 to 12).

In addition, conventional soy protein is generally inferior in odor and color, but the present inventors have further developed a soy protein that has been partially hydrolyzed using hydroalcohol to remove odor components and pigments. White has found a solution to these problems as well. The preferred concentration of hydroalcohol is 50~
It is 90W/W%.

The cosmetic oils used in the present invention include commonly used animal and vegetable oils such as castor oil, wood wax, dinoline, beeswax, squalane, olive oil, and jojoba oil, and synthetic oils such as isopropyl myristate and octyl myristate. Examples include dodecyl, octanoic acid/decanoic acid mixed glyceride, isooctanoic acid glyceride, diisostearic acid diglyceride, triisostearic acid diglyceride, diisostearyl malate, silicone oil, mineral ceresin, m-dynamic paraffin, solid paraffin, and the like. Also, a mixture of two or more of these may be used.

Cosmetic additives used in the present invention include vitamins such as vitamin A, vitamin E, vitamin E acetate, vitamin C stearard, vitamin C palmitate, and derivatives thereof, BHA, and BHT.

Antioxidants such as tocopherol, drugs such as octyl P-methoxycinnamate, oryzanol, glycyrrhizin derivatives, various plant extracts, hormones such as follicle hormone, pregnenolone, and adrenal corticosteroid, and antiseptic and antibacterial agents such as paraoxybenzoic acid ester. agents, various fragrances, etc.

These various additives are used by being dissolved in a cosmetic oil or added to an aqueous protein solution in the same manner as a cosmetic oil. Similarly, it is also possible to blend inorganic pigments such as talc, kaolin, bentonite, mica, titanium, and various organic pigments.

The present invention is carried out using the above raw materials as follows. In other words, first, dissolve the protein in 5 to 10 times the amount of water to create an aqueous protein solution. To 1 part of this aqueous solution, 0.5 to 2 parts of a cosmetic oil and various additives are gradually added and emulsified using a stirrer such as a homomixer to prepare an oil-in-water emulsion. Further, if necessary, it is also possible to achieve homogenization using a colloid mill, a high-pressure homogenizer, or the like. By spray-drying this oil-in-water emulsion, a powder (hereinafter referred to as powder capsule) whose outer shell is protein and whose interior is oil and additives is obtained. Spray drying is carried out using a normal method, with a blowing temperature of 100 to 130°C and an exhaust temperature of 60 to 90°C.
, and the product temperature is 5o~80''c.

The present invention is a cosmetic containing this powdered capsule.

The powdered capsule obtained by the present invention has an outer shell covered with protein and a cosmetic oil and additives dispersed inside. When pressure is applied, the oil inside flows out and becomes liquid. Furthermore, by adding water, the protein in the outer shell acts as an emulsifier and self-emulsifies. Therefore, emulsified cosmetics can be obtained freely from these capsules at any time. Therefore, basic cosmetics
Creams, milky lotions, lotions, etc. can be easily and freely diluted with water and prepared. .

In addition, one of the features of the present invention is that cosmetic oils contain antioxidants, vitamins, hormones, drugs, preservatives and antibacterial agents,
Since additives such as fragrances can be mixed in, cosmetics containing these can be obtained in powder form. Another feature of the present invention is that protein is used as the outer shell of the powdered capsule, and the protein acts as an emulsifier, which eliminates the drawbacks of conventionally commonly used emulsifiers. Certain safety, film feel, etc. can also be improved.

That is, the protein in the outer shell itself is highly safe, is optimal as an emulsifier for cosmetics, and has a very good texture. Furthermore, since it can be freely emulsified and used, emulsion stability is not so necessary, and the powdered capsules of the present invention and an appropriate amount of water can be added to the palm of the hand and stirred and kneaded by hand. cosmetics can be obtained.

Furthermore, since it is a powder capsule, it is easy to package the amount for one time use, and since it is coated with protein, it is easy to block air and light, making it possible to store it for a long time. It also has some features. Therefore, cosmetic oils and additives with poor stability can also be used.

On the other hand, in the case of make-up cosmetics, by destroying the powdered capsules of the present invention before use, a new diiso cosmetic that has never existed before can be obtained. For example, by kneading the pigment and the powdered capsule of the present invention, the color tone, density, and oiliness can be freely adjusted. Therefore, the user can mix the desired hue and feel according to their preference at the time of use.

It is also possible to use the powdered capsules of the present invention as raw materials for general cosmetics. In that case, it can be used in a normal formulation, and many cosmetics can be obtained by taking advantage of the emulsifying properties of the protein and the characteristics of the oil used.
