Description

Method for producing a cosmetic composition containing L-ascorbic acid {L-ascorbic acid}

The present invention relates to a method for preparing a cosmetic composition containing L-ascorbic acid, and more particularly, to an emulsion state in which L-ascorbic acid is stabilized even when various substances are added through encapsulation using an intercapsule binding inhibitor. It relates to a method for producing a cosmetic composition containing L- ascorbic acid that can maintain.

The skin plays a variety of roles, such as the ability to protect other vital organs of the body from the outside and to prevent the escape of useful components from the outside. However, as the skin ages over time, its thickness becomes thinner, the function of the skin barrier is drastically deteriorated, and thus the moisture content of the skin falls, resulting in various skin lesions. In addition, the production of highly reactive free radicals, free radicals and peroxides due to the increase of UV rays and air pollution and excessive fatigue and stress of modern people, oxidizes or denatures biological components such as proteins, nucleic acids and cell membrane lipids, It is the main cause. In particular, collagen, elastin, proteoglycans, glucosaminoglycan, laminin, fibronectin, etc., constituting skin connective tissue, are oxidized and the skin is lost. Loss of elasticity and excessive wrinkles of the skin is transformed into aged skin.

On the other hand, L-ascorbic acid (also known as L-ascorbic acid, or 'vitamin C') is known to play an important antioxidant action, preventing oxidation of polyunsaturated fatty acids and vitamins E and A in skin, blood and other tissues. (Colin Dollery, Therapeutic drugs A213pp.-A215pp, Churchill Livingstone, 1999). In particular, the L-ascorbic acid is known to have a function of removing peroxides and harmful oxygen generated in the metabolic pathway in the cytoplasm (Bendich A et al., Advanced in Free Radical Biology and Medicine , 2: 419-444). , 1986). In addition, L-ascorbic acid inhibits the activity of tyrosinase, which is involved in melanin synthesis in the skin, and reduces oxidized melanin formed by the oxidation process and converts it into reduced melanin, thereby reducing pigments such as melanin and freckles. Has the effect of improving deposition (Postaire E et al., Biochem Mol Int , 42: 1023-1033, 1997). Furthermore, L-ascorbic acid is known to be essential for the synthesis of collagen involved in the production of connective tissue associated with skin wrinkles (Padh H, Nutrition Reviews , 49: 65-70, 1991). Maintaining the content of L-ascorbic acid in skin cells has been reported as one of the most efficient ways to delay the aging process of skin (Kevin J Lenton et al., Am. J. Clin. Nutr ., 71: 1194 -1200, 2000), L-ascorbic acid has been reported to increase the production of glucosylceramide to inhibit skin aging and strengthen the skin barrier.

Therefore, research and development to use L- ascorbic acid as a cosmetic for various functions as described above has been continued, but due to the difficulty of formulation due to the instability of L- ascorbic acid to heat, light, moisture, oxygen, etc. I have been in trouble. Since L-ascorbic acid can maintain stability to a certain extent in the dry powder, there is no fear of deterioration during the shelf life, and thus there is no difficulty in commercializing a dried pharmaceutical capsule or pouch. However, cosmetics are mostly based on liquid formulations such as skins, lotions, essences, creams and the like and contain various substances such as various additives and weights in the formulations and have a long shelf life of 1 to 3 years. The altered and destroyed L-ascorbic acid changes its color from yellow to brown to dark brown, which is almost black depending on the degree of destruction. If such color change occurs during the distribution period, the product quality as a cosmetic product is greatly degraded because it can be recognized by consumers as the color change caused by the deterioration of the entire contents of the cosmetic.

L-ascorbic acid is slowly destroyed by contact with air even in a dry powder state, and the destruction rate is accelerated when light or moisture is applied. In addition, the destruction rate is accelerated even when metal ions are present in the water or when the acidity is 4 or more. Therefore, in order to use L-ascorbic acid as a cosmetic composition, a practical stabilization technique that can overcome the instability of the material by blocking the L-ascorbic acid from high temperature, moisture, oxygen and light is essential.

As a stabilization method of L-ascorbic acid developed to date, there are a derivatization method and a encapsulation method by reaction with other compounds. The derivatization method is a method of making various derivatives by combining various fats or other salts in a chemical reaction at a site which is susceptible to alteration of L-ascorbic acid, and most derivatives are relatively stable in the formulation. However, most of the L-ascorbic acid derivatives developed to date have the disadvantage that their efficacy is lower than that of pure L-ascorbic acid, and that the binding site can be exerted only by a proper enzyme in vivo to function. In addition, due to the synthesis process according to the derivatization is expensive, there may be side effects such as skin irritation due to the remaining of the intermediate or harmful solvents used in the synthesis is economically and functionally disadvantageous than pure L-ascorbic acid.

As a method of stabilizing pure L-ascorbic acid other than the derivatization method, there is a method using a silicone-based substance or oil that does not affect stabilization of L-ascorbic acid, an encapsulation method, and the like. U.S. Patent No. 5,140,043 discloses a method for preparing a cosmetic composition by dissolving L-ascorbic acid in an aqueous alcohol solution of pH 3.5 or less, but since the composition contains a large amount of alcohol, irritation is a problem in use, and thus the cosmetic composition Furnace is not suitable. U. S. Patent No. 5,843, 411 also discloses a method for preparing a cosmetic composition by dissolving L-ascorbic acid in a silicone solution and then adding gelene as a thickener. However, in the case of the cosmetic composition prepared by the above method, the deterioration of L-ascorbic acid does not occur, but gradually precipitates due to the weight of L-ascorbic acid, resulting in layer separation during long-term storage, and natural When oil is added, there is a disadvantage in that the layer separation occurs abruptly.

Accordingly, there is an urgent need for the development of a cosmetic composition containing L-ascorbic acid, which can maintain an emulsion state in which L-ascorbic acid is stabilized even when addition of various additives such as natural oil in addition to L-ascorbic acid. have.

Accordingly, the present invention has been made in accordance with the above-described demands, and an object of the present invention is to maintain a stabilized state of L-ascorbic acid even when various additives in addition to L-ascorbic acid are added. It is to provide a method for producing a cosmetic composition containing a poor acid.

In order to achieve the above object, the present invention encapsulates L-ascorbic acid by adding an intercapsule binding blocker so that L-ascorbic acid can maintain a stabilized emulsion state even when other additives are added. Provided is a method for producing a cosmetic composition containing ascorbic acid.

Commonly used encapsulation methods include a method using liposomes, a method using cyclodextrin, and a method using silicon. The method using the liposome is possible to make a nano-sized capsule by placing L-ascorbic acid inside the liposome, but due to the nature of the liposome itself, the movement of substances inside and outside the liposome occurs naturally. -Ascorbic acid is partly leaked to the outside has the disadvantage of deterioration. In addition, Korean Patent Application No. 1998-57379 discloses a method for stabilizing L-ascorbic acid using cyclodextrin. However, due to the structural encapsulation of cyclodextrin having both ends open, it is practically impossible to use L-ascorbic acid. It is difficult to achieve stabilization. The present inventors have developed a method for encapsulating L-ascorbic acid using silicone in Korean Patent Application No. 2001-11602. The method of stabilization by silicon is very excellent in stabilizing L-ascorbic acid, and maintains an emulsion state so that no layer separation occurs. However, when an active ingredient other than L-ascorbic acid is added, that is, a fragrance component or a natural oil having a large emollient function, etc., there is a disadvantage in that the separation of the emulsion occurs due to the breakdown of the emulsion state depending on the nature, type or amount of the additive. Accordingly, the present inventors have developed a method for producing a cosmetic composition containing L-ascorbic acid in which the emulsion state is not destroyed even when various additives are added by improving the method. Specifically, the present invention

(d) It provides a method for producing a cosmetic composition containing L- ascorbic acid, characterized in that the step of stirring by adding natural oil and wax or gum to the prepared capsule.

The present invention is characterized by the addition of an intercapsule binding blocker in the encapsulation of L-ascorbic acid. In the present invention, "encapsulation interfering agent" means that the L-ascorbic acid is dispersed in the silicone oil to prevent the aggregation between the capsules produced when the capsule is made to prevent the aggregation of the capsule, the surface of the capsule in the oil The tension is increased to allow the capsule to float in an emulsion state, and refers to silica, mica or a mixture thereof coated with amphipathic silicone (see FIG. 1). Specifically, the inter-capsule binding inhibitor according to the present invention is prepared by mixing the silica, mica or a mixture thereof with silicone oil, fluoroalkyl silicone, polymethyl silsquioxane or a mixture thereof, in a silicone oil.

Hereinafter, a method for preparing a cosmetic composition containing L-ascorbic acid according to the present invention will be described in more detail.

First, L-ascorbic acid dispersion is prepared by stirring and dispersing L-ascorbic acid in a mixture of ethyl alcohol and polyol. As the L-ascorbic acid, it is preferable to use an atomized crystal phase having a particle size of 20 μm or less, and preferably 1 to 20% by weight based on the total weight of the cosmetic composition.

On the other hand, silica, mica or mixed powders thereof are coated with an amphiphilic silicone and silicone oil to prepare a binding inhibitor between capsules. Preferably, a mixed powder of silica: mica = 7: 3 is used, and it is preferable to use 1 to 30% by weight based on the total weight of the cosmetic composition. The amphiphilic silicone, as mentioned above, may be used fluoro alkyl silicone, polymethyl silsquioxane or a mixture thereof, and is preferably used in an amount of 1 to 40% by weight based on the total weight of the cosmetic composition. At this time, it is preferable to add silicone oil. The silicone oil may be a vinyl dimethicone / methicone silsesquioxane crosspolymer, a polymethyl silsesquioxane, an acrylates / dimethicone copolymer, or a cyclo In the group consisting of methicone / dimethicone copolymer, cyclomethicone / dimethicone copolymer, fluoro alkyl silicone, cyclomethicone, dimethicone, cetyl dimethicone copolyol One or more selected may be used, and it is preferable to use 1 to 40% by weight based on the total weight of the cosmetic composition. Specifically, 8% by weight of vinyl dimethicone / methicone silsquioxane crosspolymer, 30% by weight of cyclomethicone and 8% by weight of cetyl dimethicone copolyol were used. In this step, the silica and mica powder surfaces are coated with polymethyl silsquioxane and fluoroalkyl groups to exhibit hydrophilic and hydrophobic amphiphilic properties, which prevent the agglomeration of the capsules in solution by interfering with the bonding between the resulting silicone capsules. You can do it.

Thereafter, the L-ascorbic acid dispersion is added to the intercapsule binding blocker, and stirred to prepare a capsule. The stirring is It is preferable to stir at 3000 rpm for 30 minutes at 35 degreeC. At this time, the size of the capsule is formed in inverse proportion to the stirring speed. If the stirring speed is fast, since the size of the capsule can be made small and uniform, it is preferable to make the stirring speed high. Specifically, the stirring speed is preferably 1500 to 3000 rpm. In addition, the size of the capsule is preferably 1 to 500㎛. 1 shows an encapsulation process of L-ascorbic acid using an intercapsule binding inhibitor prepared according to the present invention.

Thereafter, natural oil and wax or gum are added to the prepared capsule and stirred to prepare a cosmetic composition containing L-ascorbic acid. The natural oil may be used at least one selected from the group consisting of olive oil, squalane, castor oil, borage oil, prime rose oil, chamomile oil, rosehip oil, soybean oil, sesame oil and sunflower oil, specifically, in the present invention, borage oil Used.
