Cosmetic composition containing peppermint vinegar {COMSMETIC COMPOSITION COMPRISING MINT VINEGAR}

The present invention relates to a cosmetic composition containing peppermint.

Pores are the entrances where hair grows, different from pores, and the diameter is about 0.02 to 0.05 mm, and it is known that there are about 20,000 only on the face. Through these pores, sebum flows to the surface of the skin. During puberty, a lot of hormones are secreted, and the sebaceous glands become larger, and a lot of sebum is secreted. Also, when you are pregnant, under stress, and when the weather is warm, the secretion of sebum becomes active, resulting in enlarged pores.

In the late 20s, as skin aging begins, collagen and elastin, which were supporting the pore walls, are decomposed or deteriorated, so the elasticity of the skin decreases and the skin becomes dry and sagging, resulting in sagging or stretching pores. When the pores are enlarged, impurities and bacteria penetrate well, which can cause various skin diseases such as acne.

Most cosmetic ingredients have various problems, such as poor efficacy or causing side effects such as skin irritation. Accordingly, research on raw materials having an effect of promoting skin regeneration without causing skin side effects is actively being conducted. In particular, in recent years, as fermentation technology using microorganisms has been developed, the use of secondary metabolites obtained through fermentation technology from substances derived from plants or other natural raw materials as physiologically active substances is increasing. These ingredients are known to have various physiological activities and are attracting attention as new raw materials for high-functional cosmetics. Using this technology, it is expected that new ingredients that have not been used until now will be developed and applied in that it can economically produce highly functional active substances that exist in nature, but the amount is very small or difficult to apply to the skin. I'm looking forward to it. In particular, as the demands of customers for functional cosmetics have increased, the development of new functional materials or related technologies has not been sufficient. Cosmetics using fermentation technology that can produce a myriad of new functional ingredients have various skin effects, especially anti-aging. It will become very popular in the area of aging efficacy.

Mint ( Mentha piperita ) is a perennial herb of the family nectarine. It is a natural plant that has been used for edible and medicinal purposes for a long time in both East and West. Among the major components of mint, the content of essential oil is 2% to 3%, the flower leaves 4% to 6%, and the stem shows a high essential oil content of 0.3%.The main component of peppermint essential oil is 70% to 90% as menthol. , I-menthol, isomentone, pinene, camphen, limonene, and other physiological components are known to help with various skin activation and skin health. In addition, vitamin C, carotene, phytol, and betaine relieve skin fatigue and help maintain healthy and bright skin.

In an exemplary embodiment of the present invention, the peppermint is fermented with acetic acid of peppermint. Acetic acid fermentation is an aerobic fermentation in which alcohol is oxidized to produce acetic acid by the action of acetic acid bacteria . Acetobacter aceti oxidizes ethanol to produce acetic acid. In acetic acid fermentation, the logarithmic period may be about 12 to 48 hours, and the amount of acid produced increases rapidly in 12 to 24 hours. When the culture temperature of acetic acid fermentation is 30 °C, a medium containing 4% ethanol, and a pH of 6.5 to 7, the acetic acid production ability and glycolysis are most stable.

Vinegar contains more than 60 kinds of organic acids such as acetic acid, citric acid, amino acids, and succinic acid, and acts as an accelerator that helps the body absorb various nutrients such as vitamins and minerals. In particular, it acts as a blood purifying agent that cleanses our flesh and blood, promotes the metabolism of the human body, and has the effect of increasing the natural healing power to the highest level. It suppresses spots and freckles, suppresses lipid peroxidation, which is the main culprit of skin aging, and the budding of cells. It actively helps metabolism. In addition, it works to facilitate blood flow by decomposing lactic acid in the skin and muscles.

Compared to other organic acids, acetic acid has excellent blood purification, antibacterial, anti-aging, and metabolism promotion capabilities.

In an exemplary embodiment of the present invention, the peppermint is prepared by a culture method of breeding microorganisms on the surface of a liquid.

Peppermint vinegar prepared by the above cultivation method has the feature that the membrane of microorganisms is always in contact with air, so that dissolved oxygen dissolved in the liquid surface can be used well.It can be obtained through acetic acid fermentation as well as the efficacy due to the ingredients of the existing mint. It also has an advantage.

In an exemplary embodiment of the present invention, the mint is any one of leaves and stems of mint, or a combination thereof.

Mint leaves and stems have excellent sterilization and anthelmintic effects and are used in toothpaste to prevent bad breath. Grinding the leaves as a poultice is effective in treating inflammation and bruises on the skin, and is also good for dermatitis and itching. It soothes the skin irritated by large and small wounds, reduces itchiness and adverse reactions, gives vitality and stress relief to the skin, helps in light astringent action and maintains elasticity. Mint leaves contain 2% to 3% essential oil, and mint stems contain less than 1% essential oil. Mentholic acid, which accounts for about 70% of essential oils, is an ingredient that gives off the peculiar smell and medicinal properties of mint. The unique scent of peppermint can be obtained from menthol and menton, and menthol has astringent properties, pulling sagging skin and shrinking pores, giving good efficacy to the skin. In addition, it constricts the mucous membranes and blood vessels of the skin to give a refreshing feeling to the local area. Menthol, which has a unique refreshing odor, is colorless needle-like crystals, hardly soluble in water, but well soluble in ethanol and chloroform. It is obtained through the leaves or stems of mint, and when a large amount is put in the mouth, it feels like a tongue sticking, but when it is small, it feels refreshing.

In one embodiment of the present invention, the cosmetic composition contains alpha hydroxy acid (AHA: α-Hydroxy Acid). Alpha hydroxy acid is a compound in which an alcohol group or a hydroxy group is added to the carbon at the α-position of a carboxylic acid. It lowers the ionic binding energy of keratinocytes to remove hyperkeratin or to form new cells. By promoting skin aging, it shortens the cycle of the keratinization process that lengthens as the skin ages, thereby promoting the activation of skin cells and improving the skin. In addition, it promotes the production of collagen and elastin by fibroblasts to make the skin elastic and soft, and promotes the production of mucopolysaccharide, an important extracellular matrix component of the dermis, to promote skin moisturization.

In an exemplary embodiment of the present invention, the peppermint is 0.001% to 20% by weight, based on the total weight of the cosmetic composition. When the amount of the peppermint is less than 0.001% by weight, the desired effect of the present invention cannot be expected, and when it exceeds 20% by weight, a temporary feeling of irritation may appear due to the menthol component contained in the peppermint.

In one embodiment of the present invention, the cosmetic composition is for shrinking pores. Peppermint vinegar, which is fermented with acetic acid of mint, maximizes the efficacy of mint, which has excellent astringent action, prevents pores from becoming wider, and has a contraction effect that saves the elasticity of the enlarged pores.

In an exemplary embodiment of the present invention, the cosmetic composition is for controlling sebum. Peppermint vinegar fermented with acetic acid has the effect of purifying the skin's blood, antibacterial, anti-aging, and promoting metabolism, while not only removing waste products, but also enabling pore management.

The cosmetic composition according to the present invention is not particularly limited in its formulation, and for example, it may be formulated as a softening lotion, nutritional lotion, essence, massage cream, nutritional cream, pack, gel, or skin adhesive type cosmetic.

Hereinafter, the configuration and effects of the present invention will be described in more detail with reference to test examples and formulation examples. However, these test examples and formulation examples are provided for illustrative purposes only to aid understanding of the present invention, and the scope and scope of the present invention are not limited by the following examples.
