Description

The present invention relates to a cosmetic composition containing tea tree extract and salt,

The present invention relates to a cosmetic composition comprising tea tree extract and salt. More particularly, the present invention relates to a cosmetic composition comprising tea tree extract and salt, To a cosmetic composition comprising tea tree extract and salt which improves skin pulling, roughness, lack of elasticity, and the like.

The skin is largely divided into three layers: epidermis, dermis, and subcutaneous tissue in order from the outside. It has a function to protect the internal organs of the body from changes in temperature and humidity, ultraviolet rays, and other physical and chemical external stimuli.

Skin aging is caused by oxidative damage of intracellular substances by free radicals. That is, highly reactive free radicals, such as active radicals such as hydroxy radicals and superoxide radicals, oxidize the lipid components constituting the cell membrane to destroy the cell membrane, thereby oxidizing the protein and stopping the function of the nucleic acid, It destroys its components and causes cell death. Such skin aging can be caused by excessive exposure to ultraviolet rays, nutritional deficiency of skin cells, and side effects of cosmetics.

The major cause of skin cell nutritional deficiency is the inadequate nutrition of skin cells due to unbalanced nutrition such as excessive diet and irregular diet. As a result, the production of collagen in the dermal layer is inhibited and the moisture of the skin is evaporated Symptoms appear, and it also causes abnormalities in the subcutaneous fat layer, causing loss of skin elasticity.

In particular, the epidermis plays an important role in preventing water evaporation inside the human body. The epidermis is divided into stratum corneum, granular layer, superficial layer, and basal layer in order from the outside. Cells of stratum corneum act like bricks, and intercellular lipids between keratinocytes act like mortar to constitute skin barrier. In addition, a healthy human keratinocyte has a high concentration of natural moisturizing factor (NMF) to help maintain moisture in the skin. For example, substances such as amino acids are water-soluble, Thereby suppressing drying.

In addition, as the ozone layer is destroyed due to excessive environmental pollution, the particles in the ultraviolet rays form negative ions and combine with the protein molecules constituting the skin cells to generate free radicals. This is an unstable substance, And the protein of the skin cell is converted into another protein, thereby greatly damaging the skin cell. The damaged skin cell becomes unable to function as its own cell, and the skin cell becomes aged.

In addition, the side effects of cosmetics to break the harmony of fat and moisture in the skin causes skin aging. Therefore, it is possible to prevent or reduce skin aging by inhibiting oxidative damage in vivo. Antioxidant cosmetics, on the other hand, inhibit the oxidative damage of skin, including the oxidation of fat components, to prevent or delay skin aging.

However, as it is nowadays, there is a tendency to adjust the temperature of the air / heating due to the change of environment or life pattern, the stress caused by various stresses and environmental pollution in the social life, frequent washing according to make- Due to various causes such as aging of skin and the like, moisture of the stratum corneum is reduced, and the skin becomes dry, the surface becomes rough, the skin becomes loose, the luster is lost and the skin looks dull, and the need for skin moisturizing agent is increasing.

Quercetin, alpha-tocopherol, ascorbic acid, beta-carotene, hydroquinone and the like have been known to have antioxidative action so far . However, most of these substances are chemically synthesized. These chemicals are limited or limited in use due to safety concerns. If these toxic substances are continuously accumulated in the body, they may cause chronic toxicity, carcinogenicity, mutagenicity And so forth.

Maintaining a constant water content in the skin implies that it constitutes a barrier to avoid water loss, considering that water molecules evaporate.

Several kinds of lipids, sugars, and proteins are involved and interact in order for these barriers to work smoothly. According to the structural formula of hyaluronic acid (HA), double hyaluronic acid (HA) is known to be a glycosaminoglycan of a polymer present in extracellular connective tissues and acts as a barrier against moisture evaporation. It was reported to be reduced.

Long-term exposure to UV radiation, especially from external environmental factors, has a negative impact on the maintenance of a constant HA of the skin. The decrease in HA content due to these intrinsic or extrinsic factors is a factor of skin elasticity reduction, rough skin and wrinkles. Therefore, maintaining the HA content in the skin is very important for keeping skin moisturized as well as young skin for cosmetics.

The content of HA is controlled by the synthesis by continuous hyaluronic acid synthase (HAS) and the degradation by hyaluronidase (HYAL). One method of maintaining or increasing HA content in the skin is to increase the synthesis of HA while at the same time inhibiting HA degradation.

Therefore, it has been confirmed that the combination of a medicinal substance capable of increasing hyaluronic acid synthase (HAS) gene expression and a decrease in hyaluronidase (HYAL) activity or a medicinal substance having these two functions can be a method for enhancing the moisturizing power of the skin Respectively. Indeed, many natural products and substances have been reported to increase the production of HA through increased gene expression of HAS, including black rice, compound K, kaempferol, quercetin and retinoic acid isolated from ginseng.

Therefore, the present inventors confirmed the moisturizing effect in the skin moisture content measurement test through the composition of the cosmetic composition containing the tea tree leaf extract and the active ingredient of the salt, and confirmed the effect of the humankeratinocyte HaCaT on HA production and HYAL inhibition And completed the present invention.

Hereinafter, the tea tree extract and the cosmetic composition containing the salt according to a preferred embodiment of the present invention will be described in detail.

The detailed description will be made with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The characteristics and efficacy of the tea tree and salt, which are the raw materials of the cosmetic composition of the present invention, will be briefly described below.

Tea tree belongs to Leptospermum, Melaleuca, Kunzea. About 86 species are known to Leptospermum genus and about 230 species are found in Melaleuca.

Origin is native to Australia and New South Wales. It grows in a marshy area up to about 6m in height. It grows well even if it cuts its stem because its vitality is strong. It is a kind of hub that plays a role of refreshing air.

Aboriginal Australians have long been treating infections caused by cuts of leaf tea tree leaves. During the Second World War, it was paid to soldiers in the tropics as a treatment for skin wounds. It is used in surgery and dentistry. It is also used in disinfectant disinfectant, deodorant, soap, air purifier. It is also effective in various infectious diseases, cold, bad breath, athlete's foot, dandruff. However, since it is highly irritant, it is recommended to dilute the stock solution.

Because Tea Tree is highly irritant, it dilutes 2% of carrier liquid such as almond, apricot, and hazelnut, and is the most powerful immunostimulant with antibacterial and antiviral antifungal effect. It activates leukocyte, It is a substance that is used for respiratory and urinary tract infections by constructing a defense line, shortening the period of illness and antibacterial action on the respiratory system and urinary tract.

When tea tree oil is exposed to sunlight, the trace amount of paracimen is rapidly increased from 3% to 305d, and terpinene-4-ol, which has an antimicrobial effect, is oxidized and converted to trihydroxydentimene. Para-cymene has been shown to cause painful erythema and edema on the skin, and oxidized tea tree oil, when applied to the skin, not only delays the treatment of the symptoms but also causes chemical burns, Must be kept.

Staphylococcus aureus (CH Chan et al., 1998, Christine F. Carson et al., 2002) was also used in this study. Klebsiella pneumoniae (Katherine A. Hammer et al., 2004), Candida albicans (SD Cox et al., 2000), Pseudomonas aeruginosa (S. Messager et al., 2005; Katgerine A. Hammer et al., 1996), Serratia marcescens, (Tong MM et al., 1992; Andrew C. Satchell et al., 2002)), the tea tree oil has been reported to be effective against onychomycosis (Buck DS et al, , acne (Bassett IB et al, 1990), and dandruff (Satchell AC et al, 2002).

In particular, the antimicrobial activity against Trichophyton rubrum, a dermatophytic strain, was reported not only by the antimicrobial activity using a plate medium (Steven Benger et al, 2004) but also by the vapour contact (S. Inouye et al, 2001).

Tea Tree is a plant natural antimicrobial oil that has been used as a cosmetic and medicinal product because it has been used as an extract of leaves for skin diseases and has excellent antimicrobial action.

In addition, the osmotic action of salt effectively removes dead skin as well as dead skin, promoting metabolism and helping blood circulation. It also has a sterilization and anti-inflammatory effect, which not only helps alleviate rashes such as acne and rash, but also gives moisture to the skin and gives it an excellent moisturizing effect. If you eat a lot of harmful to your body is not known to be a refined salt, such as bamboo salt and Dead Sea salt minerals rich and fine salt should be used to select. It is also a good idea to use fine-grained sun-dried salt.

Therefore, if the natural salt is heated at a high temperature of 800 ° C or more for 7 to 8 hours, all the harmful substances in the salt are removed, and the heated natural salt is excellent in the moisturizing effect of the skin and the regeneration of the skin, , And when it is used together with the tea tree extract of the present invention, the effect of improving the efficacy can be obtained.

The present invention is to provide a moisturizing cosmetic composition containing 8% of natural salt of sun salted salt and tea tree extract.

In the present invention, tea tree extract can be used as an active ingredient of a cosmetic composition, and can be preferably used as a cosmetic composition. The tea tree composition contains 0.1% to 10% by weight of tea tree extract.

The tea tree extract of the present invention was classified into tea tree leaves and classified into a sample which was refluxed and extracted with 95% ethyl alcohol at room temperature for 2 hours and a sample which was refluxed twice at 50 ° C for 2 hours, followed by filtration and concentration under reduced pressure .

The tea tree extract thus obtained is highly effective in cosmetic compositions because of its high antibacterial activity against the hyaluronic aid synthase (HaCaT) for moisturizing. Accordingly, the present invention relates to a tea tree extract and a cosmetic composition containing salt which are effective for moisturizing and skin improvement.

The content of tea tree extract contained in the cosmetic composition is preferably from 0.1% to 10% by weight, more preferably from 0.1 to 5% by weight. When the content is less than 0.1% by weight, the antibacterial effect is insignificant. When the content is more than 10% by weight, there is a problem that the effect according to the usage amount is lowered.

The above-mentioned cosmetic composition can be blended with usual ingredients to be blended with common skin cosmetic ingredients such as oil, water, surfactant, humectant, lower alcohol, thickening agent, chelating agent, coloring matter, perfume and the like as necessary.

The cosmetic composition is used for the skin, and can be used for skin, cosmetic lotion, nutritional lotion, nutritional cream, massage cream, essence, pack, skin patch, skin adhesive gel, powder, soap, Suspension, emulsion, spray or cosmetics, and the like.

Hereinafter, preferred embodiments of the present invention will be described in order to facilitate understanding of the present invention.
