Description

Manufacturing method of color make-up cosmetic composition using silkworm cocoon powder and color make-up cosmetic case producted by the same}

The present invention relates to a method for preparing a composition for color cosmetics using cocoon powder, and to a color cosmetics manufactured using the same, and more particularly, to crush a cocoon in which peptide bonds are appropriately weakened by adding an acid or a base to the cocoon. There is no slipping phenomenon by using the obtained cocoon powder, and relates to a method for producing a composition for color cosmetics that exhibits excellent moisturizing power and color development power, and to a color cosmetics manufactured using the same.

Conventional cosmetic ingredients are mostly artificially synthesized compositions, and thus the effect of damaging soft skin or regenerating into healthy and moist skin is inferior.

In addition, in severe cases, it has a very serious disadvantage that can cause side effects such as skin rash or allergies.

Therefore, in recent years, attempts to use natural products having a moisturizing effect and excellent whitening effect in beauty-related products are increasing.

However, although natural products known to date can expect some degree of skin whitening effect, they do not show satisfactory properties in terms of moisture absorption and moisturizing power.

The proteins that make up the cocoon are composed of fibroin and sericin, and these proteins have excellent cell proliferation effects and can be used as a serum replacement, and have effects such as skin coating effect, moisturizing, antioxidant activity, and skin affinity, and are the main ingredients of cosmetics. It is known to be promising.

Cosmetics using silk protein were used in the production of high-end cosmetics by taking advantage of the functional effects such as moisturizing properties and biocompatibility of silk protein, but to obtain silk protein from cocoon, it was added to neutral salt (CaCl ₂ , LiBr) or acid or base. It takes a lot of time and a complicated process such as desalting process to remove the generated salt or used neutral salt while decomposing and neutralizing.

The composition for color cosmetics according to the present invention is characterized by containing cocoon powder as an active ingredient, and in more detail, a cocoon powder that exhibits excellent moisturizing power and color development power is prepared and is an active ingredient. It is characterized by producing a composition for color cosmetics that are included as.

Hereinafter, a method for preparing a color cosmetic composition according to the present invention (see FIG. 1) will be described in detail.

1. Step 1: Prepare a cocoon or refined dog

First, prepare a cocoon or refined dog to be applied as the material of the present invention.

Here, the term "cocoon" means a house made by a silkworm spitting up thread by itself, and it is generally used as a raw material for silk thread. Since these cocoons are naturally made by silkworms eating only clean mulberry leaves, they are not toxic and contain a large amount of functional ingredients, making them very suitable as a material for making color cosmetics without skin problems. The refined dog is a type of cocoon from which sericin has been removed from the cocoon, and hereinafter, the cocoon refers to a refined dog.

The cocoon is a crystalline fibrous protein and has a strong intermolecular binding force, and thus cannot be prepared in a powder form simply through pulverization. In addition, silk powder obtained through conventional hydrolysis is well soluble in water and is not suitable for use in color cosmetics. Therefore, the cocoon powder prepared by crushing the cocoon, which has moderately weakened the peptide bonds of the cocoon, does not dissolve in water, has excellent skin adhesion effect, and has good moisturizing power and color development, so it is very suitable for use as a color cosmetic composition. It is a great feature of the present invention that it must undergo the following process.

2. The second step: cocoon decomposition product manufacturing

In this step, it is an essential manufacturing process for applying the cocoon prepared as described above as a material for color cosmetics, and if explained, 0.01 to 0.5M sodium hydroxide (NaOH) or hydrochloric acid (HCl) solution to the cocoon or refined dog To prepare a cocoon decomposition product.

In other words, the cocoon is a material for color cosmetics and cannot be used simply.To make it possible to use it as a material for color cosmetics that prevents loss of its own functional ingredients as much as possible, first, a solution of sodium hydroxide (NaOH) or hydrochloric acid (HCl) It is prepared through a process of weakening the binding force between molecules using a basic or acidic solution such as, in this case, completely dissolving the cocoon as in a conventional hydrolysis process, and the silk protein of the cocoon is converted into a peptide or amino acid state. When it is hydrolyzed, it becomes soluble in water, making it difficult to use as a material for color cosmetics.

Therefore, in order to apply it as a material for color cosmetics, be sure to add a solution of 0.01 to 0.5M sodium hydroxide (NaOH) or hydrochloric acid (HCl) to the cocoon to properly weaken the peptide bond of the cocoon (see Fig. 1). It is manufactured, and through this, the bonding strength of the cocoon is weakened and the functional ingredients of the cocoon can be maximized, so that it can be used as a material for color cosmetics.

At this time, the sodium hydroxide (NaOH) or hydrochloric acid (HCl) solution is characterized by having a concentration of 0.01 to 0.5M, and when the concentration is less than 0.01M, the peptide bond of the cocoon is not easily cleaved as described above, so that pulverization is not possible. It is still difficult to apply as a material for color cosmetics, and if the concentration exceeds 0.5M, the cocoon dissolves and dissolves in water as shown in Material 2 of FIG. 2, making it difficult to apply it as a material for color cosmetics (see FIG. 2). ).

In addition, when preparing the cocoon decomposition product, characterized in that the 0.01-0.5M sodium hydroxide (NaOH) or hydrochloric acid (HCl) solution 500-1000 ml is added per 50 g of the cocoon or refined dog, wherein the hydroxide When sodium (NaOH) or hydrochloric acid (HCl) solution is applied in less than 500 ml, the cocoon's peptide bonds are not weakened and pulverization is difficult, so it is still difficult to apply as a material for color cosmetics. The content is too high, and there is a problem in that a significant amount of acid or base solution must be introduced in the following neutralization process.

In addition, when the cocoon decomposition product is prepared in this step, it is characterized in that it is performed at 100 to 125°C for 15 to 60 minutes, and when the decomposition temperature is less than 100°C or the decomposition time is less than 15 minutes, the peptide bond of the cocoon is weakened. Therefore, it is difficult to obtain the desired efficacy of the present invention, and when the decomposition temperature exceeds 125°C or the decomposition time exceeds 60 minutes, all peptide bonds are broken and it is easily dissolved in water, making it difficult to apply as a material for color cosmetics. There is a risk of loss of other functional ingredients that the cocoon has.

3. The third step: manufacture of neutral cargo

In this step, the base or acid solution used in the preparation of the cocoon decomposition product is neutralized to neutral pH using an acid or base to neutralize the cocoon decomposition product to prepare a neutralized product.

In other words, the neutralization is made of HCl when decomposed with a base or NaOH when decomposed with an acid. In this case, the concentration of HCl or NaOH used for neutralization is NaOH or HCl solution used when preparing the cocoon decomposition product Apply at the same concentration as and use a pH meter to adjust the pH to 6.5-7.0 to prepare a neutral product.

At this time, adjusting the pH to 6.5 to 7.0 irritates the skin when the pH of the cocoon decomposition product is out of the above conditions, thereby reducing the product value. In this step, the pH is adjusted in the neutralization process. Is very important.

4. Step 4: Obtaining a solid that is insoluble in water

In this step, the neutralized product is filtered to obtain a solid insoluble in water.

In other words, the neutralized material is in a state in which a silk hydrolysis solution dissolved after treatment with the NaOH or HCl solution and a solid insoluble in water (ie, a cocoon solid with weak peptide bonds) are mixed. It is characterized by obtaining a solid that does not dissolve in water and applying it as an active ingredient in a color cosmetic composition. In other words, the solution filtered through the filtration process is in a state that dissolves and disappears in water, making it difficult to apply as a color cosmetic material, whereas the solid material that is not dissolved in water remaining through the filtration has weakened peptide bonds and water It is in a state that does not melt.

Such a solid that is not soluble in water contains a component capable of exhibiting the desired efficacy of the present invention, and can be finely pulverized through the property of weakening some peptide bonds of the cocoon, and can exhibit high spreadability and moisturizing power. As a result, only solids that do not dissolve in water can be used as a material for a color cosmetic composition.

5. Step 5: Preparation of final cocoon powder

In this step, after washing with distilled water to remove salts remaining in the solid that is not dissolved in water, the final cocoon powder is prepared by drying and pulverizing it.

Through this process, it is possible to prepare a composition for color cosmetics without skin irritation, and more preferably, the final cocoon powder is 5 to 200 µm in order to smooth the application as much as possible without affecting the color development effect of the color tone. It has the best spreadability and adhesion to be crushed and used.

6. Step 6: Preparation of color cosmetics composition

Lastly, in this step, a composition for color cosmetics comprising the cocoon powder as an active ingredient is prepared, wherein the cocoon powder is contained in an amount of 0.05 to 10% by weight based on the total weight of the composition. If it is contained in less than 0.05% by weight, there is a disadvantage of having to add an additional substance due to poor moisturizing power or low skin adhesion, and if it exceeds 10% by weight, increased efficacy in covering power or fragrance according to the excess content It does not show and is not suitable in terms of cost.

In addition, the composition for color cosmetics may further include powder parts, oils, preservatives, pigments, fragrances, other additives, etc., which are commonly used as needed, such as titanium dioxide, pigments, pearls, etc. It may be used in a well-known content in the field, and is not particularly limited. In addition, the powder can be used as long as it is used in ordinary cosmetics, and the type is not particularly limited, and for example, talc, mica, talc coated with silicone, mica coated with silicone, sericite, gold There are mica, barium sulfate, kaolin, boron nitride, titanium mica, fluorine apatite, hydroxy apatite, magnesium carbonate, calcium carbonate, titanium dioxide, silica, iron oxide pigment, pearl, etc., and these are used in combination of one or two or more. I can.

It is preferable to use a silicone oil as the oil, and for example, dimethyl polysiloxane, squalane, ester oil (Ester il), and the like, but are not limited thereto.

As the preservative, benzoic acid, salicylic acid, dihydroacetic acid or salts thereof, phenols of paraoxybenzoic acid esters, halocarbons of triclosan, 1,2-hexanediol, ethylhexyl glycerin, caprylyl glycol, hydroxyacetophenone, etc. Use by mixing more than one type.

Examples of the pigment include iron oxide, titanium dioxide, zinc oxide, kaolin, talc, and the like, and any fragrance may be used as long as the fragrance is usually used for cosmetics.

Other additives include wheat germ oil, vitamin A, vitamin B2, vitamin E, ascorbic acid-2-magnesium phosphate or sodium, D-pantotenyl alcohol, dipotassium glycyrrhizinate, glutathione, UV absorber, Chelating agents, plant extracts, microbial metabolites/extracts, etc. are mentioned, and the water includes tap water, mineral water, salt water, sea water, deep sea water, ultrapure water, water derived from polar ice, mineral water. -containing water) and purified water.

In the present invention, by using the composition for color cosmetics prepared in this way, it is prepared in a formulation that can be easily used by consumers, so that it is not toxic to skin cells and has good skin adhesion, so there is no slipping phenomenon, and through excellent moisturizing power, pulling phenomenon in autumn or winter is prevented. It is possible to provide color cosmetics that can minimize and exhibit excellent color development.At this time, the formulations of the color cosmetics include makeup base, foundation, powder, eyeshadow, eyeliner, mascara, eyebrow pencil, cake eyebrow, and lip It is preferable to provide any one of color, lipstick, lip gloss, blusher, manicure, and peticure.

In particular, in the case of the above color cosmetics, water and oil enter during manufacturing, but when making water-soluble substances into color cosmetics, it is difficult to form into a powder form due to the slip phenomenon, and there is a disadvantage in that the effect is not exerted due to the interference of inorganic substances. It can be seen that maintaining the undissolved state is a great feature of the present invention, and it is in the form of a long fibrous shape as seen in the scanning electron microscope observation of FIG. 3-2, which is very effective in improving the function of mascara.

The process of manufacturing a color cosmetic such as the powder is widely known in the art, so even if a detailed description thereof is omitted herein, it is a content that can be easily understood by those in the field.
