Description

Vitamin C composition for cleaning and beauty {L-ASCORBIC ACID COMPOSITION FOR CLEANSING AND COSMETIC TREATMENT}

The present invention relates to a composition in which an unstable vitamin C (L-ascorbic acid) which is rapidly oxidatively destroyed against moisture, air, light and heat is stabilized through a binder.

In particular, high concentration of certain binders (methyl cellulose, hydroxypropyl methylcellulose, or a combination of these binders) enables stable gelation and maintains acidic properties due to vitamin C. In addition to ensuring the stabilization of C, the binder also guarantees a constant discharge of vitamin C over a long period of time.

After all, the present invention relates to a vitamin C composition suitable for use in the form of a cartridge in a shower or a bidet.

Vitamin C is necessary to maintain life, but since it is impossible to synthesize in the human body, it must be taken from the outside. Vitamin C is a cofactor, which plays an important role in collagen production. It increases skin elasticity, prevents fine wrinkles, promotes wound recovery, and helps recover after laser treatment or after surgery. In addition, by strengthening the resistance of capillaries to prevent bleeding, the function of capillary dilated skin, erythema skin, acne treatment or accelerated regeneration after decapitation. It has a whitening effect by inhibiting tyrosinase, which forms melanin pigments, and has an antioxidant action of reducing melanin, which prevents and thins pigmentation such as blemishes and freckles, as well as due to various incomplete metabolism in the body and ultraviolet rays. By removing the generated harmful oxygen, it inhibits aging, increases skin resistance and strengthens the skin.

Due to the close relationship between vitamin C and skin, many vitamin C-containing cosmetics are produced and sold. However, vitamin C is stable in the dry state of crystalline form, but it is difficult due to instability that is rapidly oxidized and destroyed by moisture, air, light and heat. It is a lot. In addition, vitamin C is known to have high stability at high pH or low pH below 3.5, but conventional cosmetics adjust the pH in the neutral region due to skin irritation concerns. Because of this, the use of vitamin derivatives in cosmetics is increasing, but the research results that the absorption of vitamin C in the skin and the conversion of vitamin C in the skin is very controversial.

Traditionally synthesized vitamin C has been used as a nutrient in the form of pills, and recently, vitamin C, which is consumed as a liquid drink, has been commercially successful. As interest in skin care is growing, the use of cosmetics is increasing.

As a technique for stabilizing vitamin C

Korean Patent Publication No. 2003-0048725 (June 25, 2003) of Bio Spectrum Co., Ltd., `` Preparation of Vitamin C Stabilized Capsule and Cosmetic Production Method Using the Same, ''

The disclosed patent is dispersed in one or two or more kinds of skin-friendly solvent, the dispersion is contained in a silicone capsule formed in the appropriate size, the capsule produced is a secondary skin-friendly silicone oil or natural oil or a complex solvent It relates to a cosmetic composition dispersed in.

In addition, Dong-A Pharmaceutical Co., Ltd. Patent Publication No. 2005-0019668 (March 03, 2005) `` Non-aqueous emulsion cosmetic composition containing vitamin C '' has been proposed a non-aqueous emulsion cosmetic composition containing vitamin C. Vitamin C is absorbed into the silicone powder using a polar solvent except water, and the pure vitamin C absorbed silicone powder is prepared in an emulsion formulation using silicone oil to minimize skin irritation by increasing the oxidation stability of vitamin C. Aims to improve whitening and skin elasticity.

Furthermore, Patent Publication No. 2006-0118908 (November 24, 2006) of Chong Kun Dang Co., Ltd., "Liquid Composition of Vitamin C Containing Carbonic Acid Gas," which discloses filling carbon dioxide gas in an aqueous solution containing vitamin C. It relates to a method of stabilizing the aqueous vitamin C solution by mixing, thereby inhibiting the oxidation of vitamin C can prevent the destruction of vitamin C dissolved in the aqueous solution, even when the liquid composition containing vitamin C for a long time storage The component of vitamin C can be stably maintained, and it aims especially at the liquid preparation for beverages.

In addition, Patent Publication No. 2004-0085825 (October 08, 2004) of IN BIONET Co., Ltd. `` Vitamin C-stabilized liquid composition '' uses CMC (Carboxymethylcellulose) to stabilize vitamin C dissolved in aqueous solution to decompose vitamin C. It suggests a way to greatly suppress this.

However, all of these published patents are for the purpose of cosmetics and beverages, vitamins are 2 to 3% by weight, low in content, high in moisture,

Due to its properties for cosmetics and beverages, the pH range is adjusted to neutral so that it does not take advantage of stable vitamin C at low pH and stabilizes with the help of other ingredients. It is not suitable to be used for cleaning and cosmetics because it is supplied in a stable amount for a long time while being dissolved by a certain amount.

On the other hand, there is a conventional technique that utilizes vitamin C for cleaning, PEM Patent Publication No. 2004-0074457 (August 25, 2004) `` Filter for removing chlorine in tap water, ''

The patent discloses a cartridge filled with powdered vitamin C and chitosan, which is used for the purpose of removing chlorine from tap water.

This means that chlorine disinfection of tap water plays a big role in controlling waterborne infectious diseases and microorganisms, but residual chlorine in tap water can be a stimulating factor for people with sensitive skin, especially when a 40 degree hot water shower is used in a confined space. As it becomes gasification and can affect nasal cavity, bronchus,

When vitamin C encounters residual chlorine in tap water, it tries to take advantage of the property of destruction.

However, the powder-type vitamin C in the published patent after chlorine removal

The amount of dissolved in water is insignificant, and as it is used, the powder state is changed into an aqueous solution state, and is destroyed by oxidation of vitamin C, which makes it difficult to use continuously.

The present invention is a binder of a high concentration of unstable vitamin C (L-ascorbic acid) that is rapidly oxidatively destroyed against moisture, air, light, heat, more specifically methyl cellulose (methyl cellulose), hydroxypropyl methylcellulose (hydroxypropyl methylcellulose) Vitamin C composition that can be stabilized gelling through a binder consisting of, or a combination thereof, in particular, stabilized of vitamin C and applied to the shower or bidet in the form of a cartridge, which is suitable for being discharged with running water and ensuring an appropriate discharge amount. The purpose is to provide.

Since there is no separate neutralizing additive, it can maintain the acidity peculiar to vitamin C to ensure the stabilization of vitamin C, and also guarantee a constant discharge of vitamin C due to the binder.

It is also an object of the present invention to provide a composition capable of maintaining a sustained water content of vitamin C for a long period of time even after removing residual chlorine in tap water due to the continuous and high concentration of vitamin C content.

In order to solve the above problems the cleaning and beauty vitamin C composition according to the present invention

It is obtained by mixing 5-30 parts by weight of a binder made of methyl cellulose, hydroxypropyl methylcellulose, or a combination thereof with respect to 100 parts by weight of vitamin C powder.

In the vitamin C composition according to the present invention, the binder is preferably a mixture of [methyl cellulose: hydroxypropyl methyl cellulose] [1: 9] to [5: 5].

In addition, the vitamin C composition according to the present invention is preferably obtained by gelation by mixing water with the vitamin C and binder mixture,

In the vitamin C composition according to the present invention, the water is deionized water or distilled water, more preferably 40 to 70 parts by weight based on 100 parts by weight of the vitamin C powder.

Furthermore, it is preferable that the vitamin C composition according to the present invention is further mixed with 0.5 to 10 parts by weight of a vitamin C stabilizer based on 100 parts by weight of vitamin C powder.

In addition, another object of the present invention is to provide a cartridge suitable for using the vitamin C composition and a shower using the same.

The vitamin C composition for cleaning and beauty according to the present invention has a skin moisturizing effect due to vitamin C when a cartridge containing such a composition is installed in a shower or a bidet for cleaning or beauty water.

As there is no neutralizing additive, the acidity peculiar to vitamin C is maintained, so the sterilizing effect of weak acidity,

Due to the continuous and high concentration of vitamin C content, it is possible to maintain the residual dissolved chlorine content of vitamin C for a long time even after removing residual chlorine in tap water, which can be expected to remove residual chlorine. It is predicted.

In addition, vitamin C as well as unstable substances when exposed to water and air, raw materials that require continuous dissolution may be prepared using the composition of the present invention a variety of cleaning and cosmetic water.

The present invention is a crystalline pure vitamin C (L-ascorbic acid) (purity of 99% or more) methyl cellulose (methyl cellulose) (hereinafter referred to as 'MC', used in combination) or hydroxypropyl methyl cellulose (hydroxypropyl methylcellulose) ( Commonly known as hypromellose (hereinafter referred to as 'HM').

It is preferable to gel the mixture by mixing water with the vitamin C and the binder mixture. Particularly, deionized water or distilled water is preferably mixed to prevent the incorporation of impurities and to maintain the shelf life. Furthermore, the distilled water is tertiary distilled water. More preferred.

In addition, it is preferable that the composition according to the present invention is further mixed with a stabilizer (for example, EDTA), skin care functional materials (for example, vitamin E and ceramide), other fragrances and pigments as an additive.

The vitamin composition according to the present invention prevents a direct reaction between the [vitamin C and binder mixed layer] and the water layer by forming a specific Sol (sol) layer on the composition gel layer when exposed to flowing water as shown in the conceptual diagram below, and between the sol layer and the water layer. It relates to a composition for dissolving a certain amount of vitamin C by the osmotic phenomenon to provide a continuously stabilized vitamin C.

Moisture layer Sol layer (reaction layer) [Vitamin + binder mixed layer]
(Gelization, solid state maintenance)

MC or HM is converted into water-soluble by attaching methyl and hydroxy propoxyl groups to insoluble cellulose, respectively. They are more stable in hot water and, when encapsulated, delay the time of exposure to moisture and air.

HM with hydroxy propoxyl group added to MC has better solubility and disintegration ability than MC. Therefore, sol layer formed when exposed to moisture is thicker than MC. This means that since the amount of vitamin C contained in the sol layer is higher, more vitamin C can be dissolved in water and discharged.

By using this property, the amount of vitamin C dissolved when MC or HM is used alone or in combination to obtain a certain amount of vitamin C can be controlled.

The composition according to the present invention is a binder consisting of methyl cellulose (methyl cellulose), hydroxypropyl methylcellulose (commonly known as hypromellose), or a combination thereof, based on 100 parts by weight of vitamin C powder. 30 parts by weight is mixed,

If necessary, stabilizers include EDTA (ex: 2-6 parts by weight), skin-care functional substances (vitamin E (ex: 2-6 parts by weight)) and ceramide (ex: 2-6 parts by weight) Etc.), other flavors (e.g., 1 to 3 parts by weight) and dyes (e.g., 1 to 3 parts by weight) are mixed to increase the functionality and commerciality.

In order to increase the convenience of transportation, storage, mounting, etc., it is preferable to mix and gel a small amount of water, in particular, deionized water or tertiary distilled water, so as to be in a form suitable for being embedded in a case such as a cartridge.

The amount of deionized water or tertiary distilled water can be appropriately adjusted as necessary, and mixing 40 to 70 parts by weight helps in gelation of a more stable composition.

In addition, since the binder has better solubility and disintegration ability than HM, MC should form a sol layer (reaction layer) appropriately for running water such as a shower or a bidet, and should be properly dissolved and drained in running water per unit time. [Methyl cellulose: hydroxypropyl methyl cellulose] is preferably used by mixing [1: 9] to [5: 5].

The invention can be better understood through the following examples.

Purely natural C (L-ascorbic acid) (purity 99) in the cartridge case (10 cm in height, truncated upper and lower conical cone-shaped case of maximum diameter Φ 6) coupled to the housing of the shower as shown in Figures 3 to 5 % Or more) 100g, a binder 15g, deionized water or tertiary distilled water 60g was prepared.

In relation to the binder, Example 1 used only a MC, Example 2 used only a HM, and Example 3 used a hybrid binder in which MC and HM were mixed in a weight ratio of 3: 7.

As a comparative example, 100 g of pure vitamin C was used without a binder, and kneaded together with the other materials, gelled, and filled into a cartridge case.

In a state where sunlight was blocked, water was added to the cartridge cases of the Examples and Comparative Examples (prepared three each) to stand for about 15 hours to form a sol layer.

Then, the inlet valve was opened to maintain a flow rate of 3.6 L / min and a water temperature of 39.5 to 40.5 ° C., and then the flow path was connected to the cartridge. After the water began to flow into the cartridge was intermittently taken and measured by HPLC (UV decter: Waters 2487, Pump: Waters HPLC 515, column: C18). In order to see the long-term vitamin solubility of the vitamin C dissolved concentration measured according to the amount of running water up to 10,000L is shown in the graph as shown in FIG.

As can be seen in the graph of FIG. 1, in the case of using the vitamin alone as a comparative example, the vitamin is dissolved more than 500ppm while being excessively stirred vigorously by the flow of water, but is oxidized or destroyed at a rapid rate over time. No water was detected after 4,000 liters of water.

In addition, as can be seen in the graph showing the vitamin C dissolved concentration measurement value related to the embodiment in Figure 2, Example 1 applied only MC as a binder showed a constant vitamin concentration of about 5ppm for a long time. This is believed to be due to the slow dissolution rate from the composition layer (gel layer) to the reaction layer (sol layer).

In the case of Example 2 to which only the binder HM was applied, the reaction layer (sol) was rapidly dissolved due to the flow of water, and thus the concentration of 50 ppm of vitamins was initially decreased, but the concentration gradually decreased. However, it did not show a sharp decrease like the comparative example.

Lastly, in Example 3, in which MC and HM were mixed and mixed, it can be seen that vitamin C is constantly dissolved in the long term at 15 to 20 ppm.

Therefore, the appropriate amount of vitamin supplied to the shower or bidet for beauty or cleaning use is a weak vitamin C discharge (for Example 1) or excessive and irregular vitamins using MC and HM hybrid binders as in Example 3 It was found that the C discharge (Comparative Example 1, Example 2) can be prevented and appropriate. In addition, by adjusting the appropriate ratio of MC and HM, vitamin solubility and cartridge life can be controlled.

In addition, in the present invention attached to Figures 3 to 5 is shown a cartridge suitable for using the vitamin C composition and a shower using the same.
