Description

PEELING COMPOSITION FOR SKIN WHITENING AND ELASTICITY {PEELING COMPOSITION FOR SKIN WHITENING AND ELASTICITY}

The present invention relates to a peeling agent composition having an elasticity improvement and whitening function, and more particularly, a peeling agent composition having an elasticity improvement and whitening function having excellent functions of whitening and elasticity improvement, as well as excellent exfoliating effect without irritation to the skin. It is about.

The most important role of the skin is to prevent heat and moisture loss from the inside while acting as a defense barrier to protect the skin from external bacterial invasion and damage. The skin is composed of several layers, and the outermost one is called the epidermis, and below it is classified into three parts: the dermis and the subcutaneous fat layer.

The epidermis is further subdivided into the stratum corneum, granule layer, play layer, and basal layer.Epidermal cells generated in the basal layer rise up to the granular layer in 14 days, and keratohyalin starts keratinization in the granular layer by the action of keratohyalin. The body fluid in the cell has already drained, and the cell is flattened and keratinization proceeds, the nucleus, cytoplasm and organelles of the cell are degenerated, replaced with keratohyalin, and changed back to Eleidin, and the last step, keratinization. As it turns into, the life of the cell ends and is pushed up into the stratum corneum. The stratum corneum is composed of differentiated epidermal cells (keratinocytes) and skin lipids that fill the gap, and it has a protective function that prevents substances in the body from going out and protects the body from external physical, chemical, and biological stimuli. Do it.

Keratinocytes are connected by a protein called desmosome, and as they go up to the top of the stratum corneum, the desmosome decomposes, weakening the cohesion between keratinocytes, and finally, the keratinocytes separate from the skin and fall apart. In the case of normal skin, the stratum corneum consists of 15 to 20 layers, and it takes 15 to 20 days to completely separate them. However, as we age, the thickness of the skin components of the epidermis, dermis and subcutaneous tissue decreases, the moisture content of the skin decreases rapidly, and the skin loses elasticity due to changes in the ECM (Extracellular Matrix) component that gives elasticity to the skin. Wrinkles are formed, the separation of the stratum corneum is slower than normal, the stratum corneum is thickened (stratum corneum), and the skin loses vitality.

Keratin layering is mainly due to the decrease in the moisturizing power of the skin, the decrease in the production and activity of desmosome decomposing enzymes, and the decrease in cellular activity, and skin aging, exposure to ultraviolet rays, and pollution are the inducing factors. By artificially thinning the thickened stratum corneum from the outside due to such internal and external factors, the activation or regeneration of living cells under the stratum corneum is increased to soften the skin, removing wrinkles, suppressing the occurrence of acne, and causing irritation. A lot of research is being conducted to resolve the stratum corneum within the range that does not exist.

To relieve keratinization, physically rub the skin or use chemical dermabrasion. In particular, chemical peeling has additional effects such as improving fine wrinkles, relieving rough skin, and removing blemishes. Materials used for chemical peeling have been mainly used as Alpha-Hydroxy Acid (AHA) and Beta-Hydroxy Acid (BHA). However, such chemical dermabrasion has a problem that the skin irritation is too large to cause various side effects.

In addition, recently, a cosmetic composition containing an AHA or BHA component has been proposed, but this also causes various side effects because the skin irritation is too large, and when the content is lowered, there is a disadvantage that the exfoliating effect is not sufficient.

Meanwhile, since the stratum corneum has a barrier function as described above, there is a problem in that even active ingredients that are beneficial to the skin cannot enter the inside. In particular, since the penetration of the active ingredient is more difficult in keratin layered skin, there is a problem that the effect is insignificant even when various functional cosmetics are used.

Therefore, when using a functional cosmetic composition, the use of a peeling agent that temporarily removes the stratum corneum, which is a skin barrier, is required.

Accordingly, an object of the present invention is to improve elasticity by including niacinamide and adenosine along with complex acids such as glycolic acid and gluconolactone, so that there is no skin irritation, excellent exfoliating effect, and maximizing the effect of whitening and elasticity improvement. And it is to provide a peeling agent composition having a whitening function.

Another object of the present invention is to provide a peeling agent composition having an elasticity improvement and whitening function that improves acne-like skin by returning alkalized skin to pH 5.5, which is the most ideal skin.

The peeling agent composition of the present invention for improving elasticity and whitening function for achieving the above object is characterized by comprising glycolic acid, gluconolactone, niacinamide and adenosine as active ingredients.

With respect to 100% by weight of the total composition, the glycolic acid 4-5% by weight, gluconolactone 1 to 1.5% by weight, niacinamide 4-5% by weight, and adenosine is characterized in that it is contained in 0.04 to 0.05% by weight.

Glycerin, butylene glycol, disodium EDTA, dipropylene glycol, purified water, 1,2-hexanediol, a softening agent, a viscosity modifier, and a surfactant are further included, wherein the softening agent is potassium hydroxide, panthenol , Allantoin, ethylhexyl glycerin, virginia apricot flower extract, oregano flower extract, hibiscus flower extract, chamomile flower extract, evening primrose extract, camellia flower extract, noni fruit extract, and hydrolyzed collagen.

Based on 100% by weight of the total composition, the glycolic acid 4 to 5% by weight, gluconolactone 1 to 1.5% by weight, niacinamide 4 to 5% by weight, adenosine 0.04 to 0.05% by weight, glycerin 5 to 10% by weight, Butylene glycol 0.01 to 0.05 wt%, disodium EDTA 0.01 to 0.05 wt%, dipropylene glycol 5 to 7 wt%, 1,2-hexanediol 2 to 3 wt%, softener 1 to 3 wt% %, viscosity modifier 1 to 1.5% by weight, surfactant 0.1 to 0.5% by weight, and the balance of purified water.

According to the present invention, there is an advantage in that the skin barrier function is restored through the keratin improvement effect without skin irritation, so that skin troubles are improved, and the function of improving elasticity and whitening is maximized.

Hereinafter, the present invention will be described in detail.

The greatest feature of the present invention is that the skin cells are removed by removing dead skin cells by using a complex acid component rather than a single component, thereby reducing irritation, while using the dead skin cell removal component and the elasticity improvement and whitening functional components together to increase the elasticity and whitening functions deep into the skin. It is said that it penetrates to improve elasticity and maximizes the whitening effect.

The composition of the peeling agent for improving elasticity and whitening function according to the present invention comprises glycolic acid, gluconolactone, niacinamide, and adenosine as active ingredients.

That is, the present invention uses a complex acid of glycolic acid and gluconolactone as an exfoliating component, niacinamide as a whitening function component, and adenosine as an elasticity improvement component, thereby minimizing skin irritation through the action of the complex acid. It is to maximize the elasticity improvement and whitening function by temporarily removing the skin stratum corneum while simultaneously penetrating the whitening function component and the elasticity improvement component deep into the skin.

The glycolic acid is an AHA component, and serves to remove dead skin cells and increase the penetration of active ingredients. Specifically, it acts to improve the skin by reducing the ionic binding energy of the keratin cells to remove hyperkeratin or to promote the formation of new cells, shortening the cycle of the keratinization process that lengthens as the skin ages, promoting skin cell activity. . In addition, by promoting the production of collagen and elastin by fibroblasts, it makes the skin elastic and soft, and promotes the production of mucopolysaccharide, an important extracellular matrix component of the dermis. It can improve skin moisturization. However, if the glycolic acid is used alone to remove dead skin cells, there is a disadvantage in that side effects such as erythema, swelling, burning, and tingling may occur, resulting in excessive irritation to the skin.

Gluconic lactone is a kind of acidic polyhydroxy acid (PHA), and serves to remove dead skin cells and increase the penetration of active ingredients. Since the gluconolactone has a large molecular weight, it is less irritating to the skin than other exfoliating ingredients and can be preserved on the skin for a long time.It maintains the skin's surface in a healthy, weakly acidic environment, and restores the skin barrier function to make the skin younger and healthier. To be able to maintain. However, this gluconolactone also has a disadvantage in that various side effects such as erythema, swelling, burning, tingling, and itching may occur if the keratin is removed by using alone.

The niacinamide is a kind of niacin, which is a group of vitamin B, and niacinamide is a water-soluble vitamin B3, also known as nicotinamide. It has the effect of reducing the water loss of the epidermis and improving the amount of lipids by simultaneously promoting the synthesis of cholesterol and fatty acids, and is used in the cosmetic field to obtain a whitening effect. The niacinamide improves skin tone, suppresses troubles, and improves skin barrier. However, since such niacinamide has little penetration into the skin due to the protective barrier of the stratum corneum, the whitening effect is insignificant. The present invention is to improve this by applying these disadvantages together with the exfoliating component.

In addition, the niacinamide may cause skin irritation when used alone in an excessive amount, but when applied together with the above-described skin exfoliating components, it rather serves to alleviate the irritation of the components.

The adenosine is a compound obtained by combining adenine and ribose, and is a natural extract, and is a component that is widely used as a therapeutic agent in pharmaceuticals prior to use in cosmetics. As the effect of improving wrinkles was proven, it was used as a cosmetic ingredient. In skin care products, it has skin-improving effects such as anti-aging, skin moisturizing, and wrinkle improvement, and in addition to wrinkle-improving effects, it has anti-aging, skin regeneration, and skin protection effects. Among the causes of wrinkle formation in the skin, it is due to the decrease in collagen and elastin that maintains the elasticity of the skin. The adenosine helps the production of collagen and elastin to maintain the elasticity of the skin, thereby preventing wrinkles.

In the present invention, based on 100% by weight of the total composition, the glycolic acid 4 to 5% by weight, gluconolactone 1 to 1.5% by weight, niacinamide 4 to 5% by weight and adenosine 0.04 to 0.05% by weight, in particular the glycerin Cholic acid 4.2% by weight, gluconolactone 1.2% by weight, niacinamide 5% by weight, and adenosine 0.04% by weight are preferable.If the glycolic acid and gluconolactone are contained less than the above lower limit, sufficient exfoliating effect appears. This is because skin irritation may be induced if it is excessive. In addition, this is because the pH is about 3.7 when included in the above range, and alkalized skin such as acne skin can be returned to pH 5.5, which is the most ideal skin. In addition, when the niacinamide is less than 4% by weight, the whitening function is deteriorated, and when it exceeds 5% by weight, skin irritation is induced. This is because it is not economical.

The elasticity improvement and whitening function peeling agent composition of the present invention constituted as described above has the advantage of having excellent exfoliating effect, elasticity improvement, whitening function effect without stimulation, and improving skin barrier to relieve troubles.

In addition, the composition of the peeling agent for improving elasticity and whitening function of the present invention includes glycerin, butylene glycol, disodium EDTA, dipropylene glycol, purified water, 1,2-hexanediol, softener, viscosity modifier, and interface. It may further include an active agent.

The glycerin (Glycerin) and butylene glycol (Butylene Glycol) serve as a moisturizing agent to continuously supply moisture to the skin. The glycerin is included in an amount of 5 to 10% by weight based on 100% by weight of the total composition, and butylene glycol is included in an amount of 0.01 to 0.05% by weight based on 100% by weight of the total composition.

The disodium EDTA is a sequestering agent for metal ions, preventing rancidity and helping skin absorption of active ingredients. The disodium EDTA is included in an amount of 0.01 to 0.05% by weight based on 100% by weight of the total composition.

And the dipropylene glycol (Dipropylene Glycol), 1,2-hexanediol (1,2-Hexandiol) and purified water are used as a solvent, based on 100% by weight of the total composition, dipropylene glycol is 5 It is contained in ~7% by weight and 2 ~ 3% by weight of 1,2-hexanediol, and the purified water is included as the balance.

The softening agent is an ingredient that helps relieve skin irritation and makes the skin soft and supple. , Gamguk flower extract, evening primrose extract, camellia flower extract, noni fruit extract, and hydrolyzed collagen. The softener is included in an amount of 1 to 3% by weight based on 100% by weight of the total composition.

The potassium hydroxide (Potassium Hydroxide) is an alkaline component and is used for acidity control. When the panthenol is absorbed into the skin, it turns into vitamin B and has an excellent anti-inflammatory effect. The allantoin also has the ability to remove dead skin cells, so it is helpful in removing dead skin cells, and has the effect of soothing skin and relieving troubles. Ethylhexylglycerin (Ethylhexylglycerin) imparts a moisturizing effect to the skin as a property of a humectant. In addition, it revitalizes the skin, helps to make healthy skin, and has excellent antiseptic efficacy. The Virginia Pomegranate flower extract controls sebum and soothes the skin. The oregano flower extract is excellent in antifungal effect, the hibiscus flower extract is excellent in exfoliating and whitening functions, the chamois flower extract is excellent in anti-inflammatory, antibacterial and antioxidant effects, and the evening primrose extract is excellent in skin whitening and wrinkle improvement It has excellent effects, and it helps to make firm and healthy skin with natural antioxidants. The camellia flower extract softens and softens the skin texture, regulates sebum, prevents skin from being oxidized, and the noni fruit extract has an excellent anti-inflammatory effect and an effect of improving skin elasticity, and the hydrolyzed Decollagen (Hydrolyzed Collagen) is a hydrolyzate obtained by hydrolyzing collagen with a high molecular weight obtained from animals and fish, and it plays a role in improving skin elasticity. In this case, each extract means that it is prepared by a general method known in the field to which this technology belongs, and it is natural that the extraction method is not limited.

As the viscosity modifier, at least one of xanthan gum, hydroxyethylcellulose, and ammonium acryloyldimethyltaurate/VP Copolymer may be used. The viscosity modifier is included in an amount of 1 to 1.5% by weight based on 100% by weight of the total composition.

The surfactant may be used without limiting its type, and as an example, PEG-60 Hydrogenated Castor Oil may be used. The surfactant is included in an amount of 0.1 to 0.5% by weight based on 100% by weight of the total composition.

On the other hand, the peeling agent composition for improving elasticity and whitening function according to the present invention may further include 1 to 2% by weight of acorn pollen extract as an active ingredient with respect to 100% by weight of the total composition.

This is because when the acorn pollen extract is further included, not only skin irritation caused by the exfoliating component is significantly alleviated, but also the whitening function is further improved and troubles are also relieved.

The extraction method of the acorn flower pot extract is not limited, and as an example, it is sufficient as long as 2 to 10 times by weight of water, ethanol or a mixed solvent thereof is added to the acorn pot, extracted for 1 to 12 hours at 20 to 100°C, and then filtered. . In addition, it is natural that it can be concentrated or dried as needed.

In addition, it is natural that the composition of the present invention may additionally contain all kinds of ingredients that can be used in conventional cosmetics, such as perfumes, preservatives, antioxidants, and the like.
