Cosmetic composition for improving hair and scalp condition {COSMETIC COMPOSITION FOR IMPROVING HAIR AND SCALP CONDITION}

The present invention relates to a cosmetic composition for improving hair and scalp conditions. More particularly, it relates to a cosmetic composition containing hydrolyzed collagen, shea butter and lanolin as active ingredients, which not only exhibits an effect of improving damaged hair, but also exhibits an excellent effect of inhibiting hair loss and removing foreign substances from pores.

Recently, as the quality of life is improved, the desire for a healthy and beautiful life is increasing, and interest in skin beauty, scalp health, and hair style is expanding. In particular, the hairstyles of celebrities, such as celebrities, are attracting people's attention through various media, and people who are sensitive to fashion tend to follow the hairstyles accordingly. In addition, many people who value appearance are giving various changes to the hairstyle of the hair that can be easily changed in order to radiate their own individuality.

Hair is an element that constitutes the skin, the organ with the largest area of the human body, and is structurally composed of cuticle, cortex and medulla. It performs various roles such as blocking UV rays, discharging waste products, and enhancing sensory ability.

The double epidermal cells constitute the outermost part of the hair, and are flat, non-nucleated, plate-shaped cells, occupying 10 to 15% of the total hair. It is as if the roof tiles are stacked on top of each other from top to bottom, or it is composed like the scales of a fish. In general, it forms a layer of 5 to 10 layers, and in some cases, it is also found that a layer of 20 layers is reached. The higher the ratio of the epidermis, the harder the hair, and the higher the strength against translucency, wetting, luster, and friction.

The shape of the epidermis overlapped in this way is called munri, and it varies depending on the shape, overlap, and site of occurrence, and individual differences vary. In addition, the hair epidermis is composed of three layers, and is composed of an epicuticle, an exocuticle, and an endocuticle, which are layers with a high keratin content and high chemical resistance.

The epidermis occupies a portion of the hair fibers and serves to protect the hair by forming a protective film inside the hair. Since the epidermis has strong lipophilic properties, it has resistance to penetration of water and drugs, and protects the cortex from the influence of external environmental factors. Therefore, if the epidermis is damaged, peeled, or shed by a physical method, the cortex is damaged.

On the other hand, the cortex is a fibrous structure located between the medulla and the epidermis, which occupies 80 to 90% of the hair, is a layer composed of cortical cells and interstitial material, and contains melanin and collagen protein. This cortex determines the color, strength and elasticity of the hair. In addition, the medulla is a structure that exists in old hair, is located inside the epidermis and contains diversified cells and voids.

Since the epidermis of hair is protected by a hard keratin protein layer, it is generally resistant to heat or stimulation. However, if strong physical stimulation or heat, repeated bleaching and dyeing, and prolonged exposure to UV light are accumulated, the hair protein is oxidized and the epidermis is damaged. will split The hair damaged by the above effect has an irregular surface, which is rough, has little luster, and is easily broken due to low tensile strength.

As mentioned above, recently, various changes have been made to hairstyles as one of the means of expressing one's individuality, and hair is damaged by permanent, friction, heat, sunlight, physical cutting, discoloration, dyeing, etc. for making such a hairstyle.

For example, when a hair dryer is used to dry hair after shampooing, the hair is dried while moisture evaporates due to heat, and the hair expands and deforms due to heat caused by the evaporation of moisture. At this time, a phenomenon such as a gradual discoloration of the black hair to brown occurs. Also, hair that is dried by heat gradually loses its elasticity.

In addition, since the permanent uses a chemical agent that modifies the protein binding form, a frequent number of permanents weakens the hair, and when an alkali component or an oxidizing agent remains in the hair, the keratin protein of the hair is denatured. In addition, frequent permanents damage the scalp that supports the roots of the hair, causing dead skin cells, dandruff, and the like, resulting in poor appearance.

In addition, if the hair is frequently dyed, the hair becomes rough and damaged as it is repeatedly exposed to the dyeing and bleaching agents used therein. In addition, if the hair is irradiated with ultraviolet light to make dyeing and discoloration easier, there is a risk that the keratin protein of the hair may be damaged or protein denaturation may occur.

In order to solve the above problems, there have been continuous studies on hair compositions for improving the softness of hair at the time of washing or after washing, and for restoring or strengthening damaged hair. As a result, various methods have been tried and developed to provide a strong and lasting hair conditioning effect.

For example, Korean Patent Application Laid-Open No. 10-2007-0038509 discloses a cosmetic agent for preventing/treating symptoms related to scalp aging by containing amino, amino acid or peptide conjugate of retinoic acid, but the effect is improved by washing. There is a disadvantage that it is significantly lowered and is not continuous. U.S. Patent No. 5490980 discloses conditioning useful for hair, skin and nails by using transglutamine that forms an isopeptide bond between lysine and glutamine among amino acids constituting protein components of the human body, such as hair, skin, and nails. A method for using as a means of delivering various active substances such as antibacterial, dye, and fragrance is disclosed.

However, transglutaminease, the enzyme used in the above inventions, is an enzyme having a molecular weight of about 38 KDa and can easily act on the surface of the hair, but it does not work on damaged parts inside the hair that actually require structural strengthening. There is a disadvantage that it is difficult, so there is a problem that the effect is very limited.

On the other hand, as modern people are frequently exposed to cosmetic environments such as hair dye and permanent, damage to the scalp, itching, and inflammation may be induced. Such itching and inflammation may affect the scalp and lead to environmental hair loss, and severe psychological pain is also accompanied when hair loss progresses.

As drugs for preventing hair loss by treating the above scalp-related diseases, topical steroids, topical immunomodulators, systemic steroids, systemic immunosuppressants, antihistamines, etc. are used, but the drugs listed above are at risk of various side effects. There is a problem with

Accordingly, in order to solve the above problems, the present applicant has applied hydrolyzed collagen, shea butter, and hydrolyzed collagen as a cosmetic composition that can exhibit an improvement effect on damaged hair, a hair loss inhibiting effect, and an improvement effect on scalp-related diseases such as seborrheic scalpitis. A cosmetic composition for improving hair and scalp conditions including lanolin as an active ingredient has been developed.

Collagen is an insoluble cross-linked protein produced and secreted by fibroblasts of the skin and is present in the extracellular matrix, and accounts for 30% of the total weight of biological proteins. Collagen is a major fibrous protein that forms skin, bone, cartilage, and blood vessels. Its main functions include mechanical firmness of the skin, resistance of connective tissue and tissue bonding, support of cell adhesion, and induction of cell division and differentiation. known (Ann NY Acad Sci. 1990;580:8-16). In particular, collagen constitutes more than 90% of the dermal layer, and when collagen is destroyed by ultraviolet rays, stress, active oxygen, etc., skin elasticity decreases and skin wrinkles occur (Arch Dermatol. 1989;125(8):1150). . In addition, since collagen has its own water retention ability, when collagen is destroyed, the skin becomes dry and rough (J Ginseng Res 31(2):86-92, 2007; Toxicol Appl Pharmacol 195: 298-308, 2004). There are a total of five types of collagen, and in particular, type-I collagen is a collagen type that has been reported to have a close relationship with skin elasticity and skin moisture.

Hydrolyzed collagen is a mixture of small peptides obtained by hydrolyzing the collagen having a large molecular weight, and specifically, a by-product contained in the bones and skin tissues of animals such as fish, horses, pigs and rabbits. It is obtained through the action of hydrolysis using acid or alkaline enzymes. This hydrolyzed collagen contains a large amount of amino acids, mainly glycine (Glycine), proline (Proline) and hydroxyproline (Hydroxyproline) occupies about 50%. The concentration of the glycine and proline contained in the hydrolyzed collagen is characterized in that it contains up to 20 times more than the general protein food.

On the other hand, the collagen has a disadvantage of relatively poor skin absorption due to its large molecular weight. Hydrolyzed collagen compensates for this disadvantage and is a water-soluble form of collagen for use as a component of water-soluble cosmetics. changed ingredients. The water-soluble hydrolyzed collagen is being added as an ingredient for moisturizing and wetting in conditioners, moisturizers, and topical creams, etc., using the property of being easily and quickly absorbed into the skin.

The shea butter is a vegetable oil extracted from the fruit of the shea tree, which has been used for a long time as a folk remedy in Africa, and is known to have a very high effect on regenerating wounds by supplying moisture to rough and dry skin. It is widely used as a moisturizer or emollient in cosmetics. The shea tree, called karite in French, grows in Africa, such as Mali, Cameroon, Congo, Ghana, Guinea, Senegal, Sudan, Nigeria, Burkina Faso, Uganda, and Côte d'Ivoire, Vitellaria Paradosa. (Vitellaria paradoxa). In particular, shea butter is said to be derived from the shape of the fruit of the shea tree, which resembles butter.

The shea butter is yellow-green oil and has good flavor and flavor, so it is used for food in West Africa. It is used as a substitute for cocoa butter when mixed with cocoa or when making chocolate. Shea butter is known to have antioxidant and anti-inflammatory effects in addition to moisturizing and regenerating the skin, and shea butter also has a UV protection effect, which is approximately SPF (sun protection factor) 6. In addition, it is used as a hair conditioner because it stimulates capillaries to moisturize the hair and scalp, and increases nutrition and regeneration.

On the other hand, there are two methods of extracting the shea butter. Specifically, a chemical method of extracting only fatty acids formed in a liquid state by melting whole seeds using a hexane-based chemical, and grinding, boiling, and watering the seeds without a chemical solvent There is a non-chemical method of extraction by evaporation.

The lanolin (lanolin) is a natural oil extracted from sheep's wool, also called sheep's milk (羊油). When washing wool, wool paper obtained by centrifugation or solvent extraction from waste liquid is dehydrated lanolin, and purified lanolin is obtained from this. It is said that the reason sheep can live outdoors even in the cold winter is because lanolin oil protects the wool from the cold. After shearing the sheep, lanolin oil, a secretion from the sebaceous glands of sheep, envelops the entire sheep's body, softening and replenishing moisture, and acts as a natural skin lubricant to protect the skin. In addition, the lanolin has the characteristic of softening the skin with excellent hydration, and it can maintain the normal humidity of the skin without inhibiting the normal excretion of moisture from the epidermis, as well as keep the skin clean and supple and prevent dryness. There are features that play a role.

Furthermore, as lanolin is rich in vitamin E and pure fatty acids, it is quickly absorbed into the skin and plays a role in promoting cell regeneration, so it is excellent in treating and regenerating damaged skin enough to be used as an ointment ingredient. It is effective for dry skin and is known to be effective in removing dead skin cells such as heels and elbows.

Using these characteristics, it is also used as a raw material for cosmetics, and because it is quickly absorbed into the skin, it is used as a raw material for various ointments and natural soaps.

The cosmetic composition for improving hair and scalp conditions of the present invention contains the hydrolyzed collagen, shea butter, and lanolin as active ingredients, thereby supplying nutrients to damaged hair and scalp due to the mixing action of these ingredients to provide nutrients to the hair. Not only can it strengthen the strength of the skin and enhance its luster, it can also suppress hair loss and effectively remove waste products accumulated in the pores.

The cosmetic composition includes purified water, and contains 30 to 50 parts by weight of hydrolyzed collagen, 10 to 30 parts by weight of shea butter, and 10 to 30 parts by weight of lanolin based on 100 parts by weight of the purified water.

Preferably, the cosmetic composition of the present invention may further include cinnamon honey and weasel extract.

Acer ginnal grows in mountains and fields, and is about 8m high. The bark is blackish-brown, and the whole is hairless, and the leaves are opposite and triangular or oval or egg-shaped, and the lower part is often divided into three. The leaves are 4 to 8 cm long and 3 to 6 cm wide, with deep burrow marks and double saw teeth on the edge. The outer surface of the leaf is shiny and the tip is long and sharp, and the petiole is 1 to 4cm long and red. Flowers bloom in May to July in yellowish white, and hang in a double inflorescence, fragrant. There are bisexual and unisexual flowers. The calyx piece is long egg-shaped, and the petals are oval-shaped, with 5 each. There are 8 to 9 stamens and 1 pistil, and white hairs are densely formed. The fruit is a citrus fruit, about 3.5cm long, with both wings almost parallel or overlapping, and ripens in September to October. In addition, since ancient times, cinnamon has been used in folk remedies and oriental medicine for ophthalmic diseases, wound healing, and antidiarrheal. As for the study on the composition of Shin tree, there have been reports on the composition of several flavonoid-type compounds including quercetin, saponin-type compounds and tannin-type compounds including acertannin, mainly from leaves and stems. Among the previously reported component studies, the biggest characteristic of the phenolic compound isolated from cinnamon is acetyltannin, a galloyl glucitol compound in which 1,5-anhydroglucitol is bound to the mother nucleus and a galloyl group. It can be said that the compound is a characteristic polyphenol contained in cypress, which has not been found in other plants (Woo, 1962; Bock et al., 1980; Park et al, 1996). In addition, as a study on the physiological activity of Shin tree, antioxidant activity based on strong free radical scavenging activity, anti-cancer and anti-mutagenic activities, etc. are known by mainly using pre-extracts from leaves and gallotannin compounds isolated therefrom ( Choi et al., 2005).

Shinnamu honey is a honey harvested from the flower of the cinnamon tree, and it is attracting attention as a health functional food because it contains a lot of royal jelly and natural antibiotic propolis. In addition, it contains monosaccharide form of sugar, so it is used as a component of a fatigue relieving agent, and a large amount of magnesium acts to relieve nerve pain. Furthermore, it is rich in iron, which helps relieve anemia and cold symptoms.

The weasel (Amorpha fruticosa) is a dicotyledonous plant, a deciduous shrub of the Rosaceae leguminous family, and is also called joksari or dwarf sage. The leaves are like sagebrush, and the seeds are similar to white bean pods. The height is about 3m, and there are hairs on the branches, but they gradually disappear as they grow. The leaves are alternate phyllotaxis and are pinnate compound leaves. The small leaves are 11 to 25 each, and they are egg-shaped or oval, and the edges are flat. Flowers bloom from May to June, are light blue with a purplish color, and have a strong fragrance. The fruit bears fruit in September and is a conifer. The fruit contains 1 seed and is kidney-shaped.

The leaves and stems of Weasel contains amorphin, which is decomposed into amorphigenin, glucose, and arabinose through hydrolysis. The amorphine contained in weasels is known to have a cardiac action and a sedative action on the central nervous system, suppress conditioned reflexes, lower the electrical activity of the cerebral cortex, and inhibit the transmission of excitation to the vagus nerve. and slows the contraction of the heart.

In particular, the cinnamon honey of the present invention has a characteristic that the active ingredients contained in the honey can be maintained as it is because the honey is not heat-treated unlike general honey. Therefore, by additionally including cinnamon honey in the cosmetic composition of the present invention, it is possible to strengthen the strength of damaged hair and enhance gloss through the action of active ingredients present in cinnamon honey, as well as inhibit hair loss and remove waste products accumulated in pores. can be effectively removed. Furthermore, when the weasel extract is additionally included, it may exhibit a synergistic effect on the hair improvement effect.

More specifically, each of the honeysuckle honey and the weasel extract may be included in an amount of 5 to 10 parts by weight based on 100 parts by weight of the purified water.

When it is within the above weight range, a clear synergistic effect of improving the damaged hair, suppressing hair loss and removing foreign substances from the pores appears due to the mixing action between each component, and if it is less than or exceeding the weight range, the effect is insignificant.

More preferably, the cosmetic composition of the present invention may further include 5 to 10 parts by weight of a cypress tree extract and 5 to 10 parts by weight of a cypress tree extract based on 100 parts by weight of the purified water.

The Hemiptelea davidii is a deciduous broad-leaved arboreous tree belonging to the Rosaceae Elmaceae, and is native to Korea and Manchuria, and there is only one species in one genus in the East. It is a tall tree that loses its leaves in winter and grows to about 15 to 30 m and grows well in sunny places. The bark is grayish-brown or black-gray, and is deeply fissured vertically. There are many elongated thorns that have changed young branches on the branches. The leaves are alternate phyllotaxis, long oval or elliptical, with a sharp tip and serrated edges. The length is 1-6cm, the side veins are 8-15 pairs, and there are hairs on the veins on the back side of the leaves. In May, 1 to 4 pale yellow flowers bloom in leaf axils. The genus name Hemiptelea is a compound word of 'hemi' meaning half and 'ptelea' meaning wing. As a medicinal effect, the root bark of cypress tree is used to treat kidney stones by helping to actively diuretic and excreting urine. In addition, it is effective in removing swelling and has the effect of removing heat and inflammation caused by moisture. In addition, it is used to treat swelling (腫脹), sore throat (惡瘡) and angjeo (癰疽).

The Lonicera caerulea is a dicotyledonous plant of the Pseudomonas family, a deciduous shrub reaching a height of 1.5 m, with many branched branches, shield-shaped bracts at the nodes of small branches, and a white inner part of a tree trunk. The leaves are opposite, lanceolate or oval, and both ends are blunt or sharp, have no saw teeth, have short hairs on the edge and surface, and have many villi on the back side. Flowers usually have a short peduncle and hang on the leaf axil, and the corolla is funnel-shaped, pale yellowish white, and blooms in summer. The calyx is divided into 5 pieces, and the corolla is yellowish-white, cylindrical, bell-shaped, 1.2-1.5cm long, and has some hairs. In addition, the stamens are shorter than the style, and there are no hairs, and two ovaries are combined. The serrata is distributed in Siberia, Sakhalin, northern China, Tibet, and North Korea, and can be found in Gangwon-do, Hamgyeong-do, and the ridge of Mt. Halla in South Korea. In terms of the pharmacological activity of dandelion plant, the effect of preventing and treating diseases such as hepatitis, liver cirrhosis or fatty liver, and the effect of removing hangover from the extract of dandelion tree fruit is known.

In the case of a cosmetic composition further comprising 5 to 10 parts by weight of a cypress tree extract and 5 to 10 parts by weight of an extract of sycamore tree relative to 100 parts by weight of the purified water, nutrients are more effectively supplied to damaged hair and scalp by the mixing action between these extracts. Not only can it strengthen the strength of the hair and increase its shine, but it can also maximize the effect of suppressing hair loss and removing waste products accumulated in the pores.

The cosmetic composition has an excellent improvement effect on scalp-related diseases, and the scalp-related diseases are selected from the group consisting of seborrheic scalpitis, contact scalpitis, atopic scalpitis, ringworm of the scalp and scalp psoriasis.

The seborrheic scalpitis is a chronic inflammatory skin disease that tends to occur on the scalp, which is a region where sebum is secreted, and erythema (red spots) and thin scales (dandruff) are common. It is easy to appear within 3 months of life and between 40 and 70 years of age, and is a very common disease, especially occurring in 3 to 5% of adult males. The cause of seborrheic scalpitis is still unknown, and it is predicted that various factors such as genetic factors, family history, and food act. Among them, the development of sebaceous glands, yeast bacteria (phytyrosporium), neurotransmitter abnormalities, mental stress or insomnia, drinking alcohol, nutritional deficiencies, and changes in temperature and humidity are some of the strong ones. Symptoms include red spots, dandruff, scabs, etc., which are usually accompanied by itching. In particularly severe cases, hair loss may also occur.

The contact dermatitis is scalp inflammation that occurs when the scalp is exposed to substances that irritate the skin or cause an allergic reaction. According to the cause of inflammation, it is divided into irritant contact dermatitis and allergic contact dermatitis. The cause of contact scalpitis occurs when toxic (toxic) or irritating chemicals come into contact with the scalp. It can occur depending on factors such as the condition of the scalp, age, and environmental factors (temperature, humidity), etc.

The atopic scalpitis is a scalp eczema disease that chronically recurs and is accompanied by severe itching. Atopic dermatitis is one of the representative allergic diseases. It is known that atopic scalpitis is caused by a combination of factors such as the patient's genetic predisposition and environmental factors, the patient's immunological abnormality, and the scalp barrier abnormality. In addition, more than 80% of patients show immunological abnormalities, resulting in an increase in immunoglobulin E (IgE) in the blood. Symptoms of atopic scalpitis include severe itching and are very sensitive to external stimuli or allergens. Itching usually intensifies in the evening, and at this time, it is characterized by eczematous changes in the scalp by scratching the scalp. Furthermore, when the eczema gets worse, the itch becomes more severe again, repeating a vicious cycle. As a treatment for this, topical steroids, topical calcineurin inhibitors, antihistamines, immunomodulators, and antivirals are used, but there is a problem that a cure is difficult and resistance may develop.

Ringworm of the scalp is a disease caused by a fungus called M. canis as a causative bacterium and is accompanied by severe inflammation. The hair falls out or breaks easily, forming large, scaly, gray or reddish spots on the head that are round or oval with well-demarcated boundaries. Occasionally, a severe inflammatory reaction forms a pus sac accompanied by tenderness and discharges pus, and symptoms such as extensive hair loss and enlarged neck lymph node may be temporarily observed. For the treatment of ringworm, oral antifungal agents such as Griseofulvin, Itraconazole, and terbinafine are used.

The scalp psoriasis is a disease in which scalp cells proliferate abnormally and rapidly due to autoimmune abnormalities or genetic or environmental factors, and is a disease different from simple dandruff or dryness. Scalp psoriasis causes itching and at the same time, scalp keratin often falls on clothes or shoulders. In severe cases, it can cause hair loss. There is a method of treatment using steroids, etc., but it is one of the scalpitis that is not easily treated.

In the present invention, there is an effect of improving the scalp-related diseases by the mixing action of the active ingredients contained in the cosmetic composition.
