Description

Cosmetic composition for whitening and decolorization using generator oxygen {COSMETIC COMPOSITION FOR WHITENING AND BLEACHING USING NASCENT OXYGEN}

The present invention relates to a cosmetic composition for whitening and decolorizing using generator oxygen, and more particularly, it can be safely used without side effects on the skin, and the whitening and skin tissue damage of the skin whitening, skin disinfection, and skin massage effects are effective. The present invention relates to a composition that can also be used as a cosmetic for bleaching that can be less discolored.

Human melanin pigments are synthesized in melanosomes, which are organelles in melanocytes (melanosyte), first forming a skeleton of the melanosomes, and tyrosinase is first arranged on the skeleton, followed by biosynthesis of melanin. Looking at the synthesis route of melanin, tyrosine (tyrosine) is oxidized to dopa (DOPA), dopa quinone (DOPA-quinone) is produced at the stage of oxidase called tyrosinase (tyrosinase) is involved. The reaction then proceeds automatically oxidatively, but it is also known to be more accelerated in the presence of enzymes. There are various natural chemicals made up of proteins in the human body. Each chemical amino acid plays its role, but black melanin, red melanin, and mixed melanin, which are formed from tyrosine, an amino acid related to color, form granules. The degree of distribution according to the amount of distribution reveals a unique skin color for each person. In other words, it can be said that it determines various skin colors according to the type of melanin and the size of granules.

When such synthesis of melanin occurs excessively in the skin, it may darken the skin tone and cause blemishes and freckles. Therefore, by inhibiting the synthesis of melanin pigment in the skin, not only can brighten the skin tone to realize skin whitening, but also improve skin hyperpigmentation such as spots, freckles, etc. caused by ultraviolet rays, hormones and genetic causes. have.

A typical skin whitening practice is to remove the upper part of the skin by applying chemical burns by phenol, which is performed by dermatologists, which causes pain in the patient and thoroughly blocks UV rays for about 10 days. It is a hassle to avoid exposure to sunlight for two to six months.

In addition, the conventional cosmetics for whitening ointments, essences, etc. substances having inhibitory activity against tyrosinase such as hydroquinone, ascorbic acid, kojic acid, glutathione, etc. In combination with cosmetics to achieve skin whitening or improve skin hyperpigmentation such as blemishes and freckles. However, although hydroquinone exerts a predetermined whitening effect, skin irritation is severe and there is a problem of limiting the compounding amount to a very small amount, and there are people who cause hypersensitivity reactions. Ascorbic acid is easily oxidized, and cosmetics containing the same cause problems such as discoloration and deodorization, and kojic acid is unstable in a solution, which makes the manufacturing process of the cosmetic complex. In addition, thiol-based compounds such as glutathione and cysteine not only have a characteristic unpleasant odor, but also have problems in transdermal absorption, and glycosides and derivatives thereof are also highly polar and thus difficult to use as a constituent of cosmetics. Placenta extract, on the other hand, has no irritation to the skin, but lacks a whitening effect.

Therefore, the inventor of the present invention knows that the basis for coloring the skin and hair is melanin pigment, and it is the generator oxygen that blocks the melanin pigment. I came to think of a new way of trying.

The present invention has been proposed in view of the above-described problems of the prior art, and an object of the present invention is to generate generator oxygen using a reaction of an acid and an alkali to induce the destruction of melanin pigment, without damaging the skin and hair. The cosmetics are applied to achieve the whitening of the skin and the bleaching of the hair.

Still another object of the present invention is to provide a cosmetic composition that can be used for discoloration of the hair and at the same time having the effects of skin disinfection and skin massage as well as skin whitening.

In order to achieve the object as described above, the whitening cosmetic composition according to the present invention comprises a first paste containing a peroxide and a second paste containing a chloride catalyst for activating the peroxide, and thus, the mixture of the first paste and the second paste. Whitening effect is generated by using generator oxygen.

The peroxide of the first paste is selected from the group consisting of hydrogen peroxide, barium peroxide, sodium perborate, calcium peroxide, urea peroxide, and the catalyst of the second paste is sodium hypochlorite (NaOCl), sodium chlorite (NaOCl ₂ ). , Sodium chlorate (NaOCl ₃ ), calcium hypochlorite (CaCl ₂ O ₂ ), calcium chlorate (CaCl ₂ O ₆ ), magnesium chlorate (MgCl ₂ O ₆ ), aluminum chlorate (AlCl ₃ O ₉ ), potassium chlorate (KClO ₃ At least one selected from the group of chloric acid compounds and catalase.

The peroxide of the first paste is hydrogen peroxide, and the catalyst of the second paste is preferably sodium hypochlorite.

Hydrogen peroxide may be contained from 1% to 12% for the first paste premises, and sodium hypochlorite may be contained from 1.7% to 20% for the entire second paste.

Preferably, the amount of hydrogen peroxide is at least 3% and less than 12% of the weight of the first paste, and the amount of sodium hypochlorite is at least 5% and less than 20% of the weight of the second paste.

The first paste and the second paste are packed separately in a double container with a diaphragm or in separate containers, and the first paste and the second paste are combined in a weight ratio of about 1: 1 when used. As the double container for storing the first paste and the second paste of the present invention, the "paste material discharge container" of the patent application No. 2002-0014643 filed by the present inventor can be used.

Hereinafter, explanation will be made based on the embodiment of the present invention using hydrogen peroxide as the peroxide and sodium hypochlorite as the chloride catalyst. However, the following examples are only intended to specifically illustrate the present invention, it is obvious to those skilled in the art that the scope of the present invention is not limited. Therefore, simple modifications or changes of the present invention can be easily carried out by those skilled in the art, and all such modifications or changes can be seen to be included in the scope of the present invention. That is, the rights of the present invention are not limited thereto, and apply to the whitening cosmetic composition using various peroxides and catalysts.

Hydrogen peroxide is a chemical that is widely used in the production of bleaches, oxidants, derivatives, etc., and also has great sterilizing power. When decomposed, it decomposes into water and oxygen. Alkaline (pH 10-12) has strong bleaching power.

In contrast, sodium hypochlorite, a chlorine-based bleach, has a rapid reaction and bleaching power under acid or pH 7.

Thus, the present inventors made the composition such that the first paste containing hydrogen peroxide maintains strong acidity and the second paste containing sodium hypochlorite remains strong alkali. Therefore, hydrogen peroxide and sodium hypochlorite remain stable in the first and second pastes without reacting, and the acid and alkalinity are neutralized by mixing the first paste and the second paste when using the whitening cosmetic composition of the present invention, and sodium hypochlorite. Peroxide and hydrogen peroxide will react.

In the present invention, the disinfection power and the bleaching power of the sodium hypochlorite and the disinfection power and the bleaching power of hydrogen peroxide are used simultaneously. When the sodium hypochlorite and the hydrogen peroxide are used simultaneously, the chemical reaction is as follows.

NaOCl + H ₂ O ₂ ----> NaCl + H ₂ O + O ₂

In other words, as can be seen in the above formula, hydrogen peroxide reacts with hypochlorous acid to generate oxygen. Oxygen can be easily obtained due to the reaction of acid and alkali, where the reaction takes place, and it is a chemical reaction that can maximize disinfection and hydrogenation of hydrogen peroxide and sodium hypochlorite.The reaction product is not only oxygen but also salt (NaCl) and water (H2O). So you can get the effect of skin massage with salt water.

Catalase (catalytic enzyme) may be used as an enzyme capable of decomposing hydrogen peroxide. Oxygen gas generated by decomposing hydrogen peroxide has a sterilization and disinfection effect. Catalase, like peroxidase (peroxidase), is an enzyme that catalyzes the reaction of two molecules of water and one molecule of oxygen from two molecules of hydrogen peroxide. It is present in all organisms except anaerobic bacteria. Catalase and peroxidase are called by the common name of hydroperoxidase. Catalase is assumed to catalyze the reaction of H ₂ O ₂ + H ₂ O ₂ → 2H ₂ O + O ₂ , and peroxidase catalyzes the reaction of H ₂ O ₂ + R (OH) ₂ → 2H ₂ O + RO ₂ do. That is, the two reactions have similar properties. The decomposition of hydrogen peroxide into water and oxygen by catalase is understood as a special reaction of peroxidase.

Meanwhile, the cosmetic composition according to the present invention is filled in a double container with a diaphragm such that the first paste containing hydrogen peroxide and the second paste containing hypochlorous acid are mixed and reacted only when used. Alternatively, the first paste and the second paste may be filled in separate containers, and then discharged and mixed when used.

In the double containers with the diaphragm, the same amount of the first paste and the second paste is preferably discharged.

The cosmetic composition of the present invention adopts the formulation developed by the present inventors to make the pH of hydrogen peroxide constant, and the cosmetics containing sodium hypochlorite, which is also the second paste, have been developed by the present inventors to maintain the constant pH. Sanctions were adopted. The material of the 1st paste and the 2nd paste of this invention is as follows.

The cosmetic composition according to the present invention is in liquid, solid, gel or foam form, and includes general ingredients as a humectant, a foaming agent, a binder, a perfume, and other ingredients.

Sorbitol and glycerine of the first paste inhibit the evaporation of moisture in the cosmetic composition to prevent aging when the phase is exposed to air.

Sorbitol gives a refreshing feel to consumers who use cosmetics because the heat of dissolution of sorbitol causes endothermic activity at -26.5 ℃. Sorbitol solution has faster moisture exchange rate, that is, water and moisture absorption rate is faster than glycerin.

Xanthan gum was used as a binder to bind the inorganic powder component and the liquid component insoluble in water in the cosmetic to prevent separation over time to impart viscosity to the composition. Fumed silica has the effect of thickening the mixture and absorbing the effluents from long-term storage.

Methyl salicylate and the peppermint of the second paste were used as a flavor to minimize the unpleasant odor.

The paste of the present invention may contain a pH adjuster for adjusting pH. In the present invention, the pH adjuster makes the pH of the paste optimal to prevent the peroxide or chlorate compound in the first and second pastes from reacting in the paste. Acetate, phosphate, citrate, triethanolamine, carbonate can be used as the pH adjuster to keep the first paste acidic, and citrate (citric acid) was used in the composition of Table 1 above. Sodium hydroxide, barium hydroxide, potassium hydroxide, and the like may be used as a pH adjusting agent for maintaining the second paste in an alkaline state, and sodium hydroxide was used in the composition of Table 1 above.

Experimental Example

Among Asians with general skin, 50 were composed of Koreans. In each example, 10 people were used. When using the cosmetic composition according to the example, the first paste and the second paste were stopped for about 5 minutes at the left hand for about 5 minutes in the evening and about 2 cm to 5 cm below the ring finger, once a day using about 1 g. Rub while mixing. After about three months, the whitening difference between the paste and the paste containing hydrogen peroxide and sodium hypochlorite was obvious in the right portion while mixing the first paste and the second paste on the back of the hand.

Minolta's color-reader (CR-300) was used for the color-reading. The larger the color reading, the whiter the skin. The table below shows the increase in color reading depending on the period of use.

Referring to the effect of the experimental group in the case of using the cosmetic composition according to the embodiment of Table 2 to Table 5, as shown in Table 2 it can be seen that when the hydrogen peroxide 1% and sodium hypochlorite 1.5% has little effect on the skin whitening In the case of using 12% hydrogen peroxide and 20% sodium hypochlorite, that is, in Example 5, the experiment was discontinued due to unpleasant odor and redness of the skin on the back of the hand.

Therefore, the hydrogen peroxide is preferably contained in less than 3% and less than 12% of the first paste as a whole, and the sodium hypochlorite is preferably contained in the total weight of the second paste in an amount of 5% or more and less than 20%.

The above embodiment was tested for use as a cosmetic for whitening, but it can be applied to cosmetics for discoloration as well, and in the case of cosmetics for decolorization, it is preferable to be contained in the same weight as described above.

Depigmentation is the use of the property of melanin pigment breakdown by certain chemicals to brighten the color of the hair. The oxidant used for decolorization usually uses hydrogen peroxide or urea peroxide. In general, ammonia is mixed to promote the decolorizing action of hydrogen peroxide. Oxygen, which is produced when hydrogen peroxide and ammonia are mixed, destroys the dark pigments in the cortex and causes discoloration. Usually ammonia is mixed with ammonia at 28% concentration.

In the case of the commonly used depigmentation agent when the content of hydrogen peroxide reaches 35%, the hair color is severely damaged and also damages the scalp, whereas when the cosmetic composition of the present invention is used for hair depigmentation Since the content of hydrogen peroxide is less than that used in general, the effect of discoloration is excellent while significantly reducing damage to hair and scalp. In addition, most of the bleaching agent is configured to neutralize by applying a second paste after a predetermined time after the first paste is applied, which mainly contains a high concentration of hydrogen peroxide, damage the hair and scalp, the first Since the second paste is applied after a predetermined time after the paste is applied, the process is complicated and if the time passes by mistake, the degree of damage to the hair and the scalp is increased. By using the paste and the second paste at the same time, there is no use of a separate neutralizing agent, which makes it easy to use a decolorant, and since salt water is generated as a reaction product of the first paste and the second paste of the present invention, there is an advantage of not damaging the scalp. Here, the bleaching agent includes agents for dyeing and bleaching used in beauty salons and commercially available hair bleaching dyes.

In the composition consisting of the first paste and the second paste as shown in Table 1, a cosmetic composition for whitening, to which a conventional composition known in the art generally used in cosmetic compositions may be added, may be used. Such cosmetic compositions for whitening include flexible lotion (skin lotion), essences, creams, nourishing lotion (milk lotion), packs, and the like, and the composition and ratio of the composition vary depending on the type of cosmetic. The composition of the composition according to each type of cosmetics is composed of the following Table 6.
