Description

Cosmetic composition containing herbal extract and nano ceramide {COSMETIC COMPOSITION CONTAINING ORIENTAL HERB EXTRACT AND NANO CERAMIDE}

The present invention relates to a cosmetic composition, and more particularly, by containing a large amount of complex herbal extracts and nano-stabilized nano ceramides, herbal extracts and nano ceramides for preparing solubilized and emulsified cosmetics that can improve troubled skin. It relates to a cosmetic composition containing.

In general, ceramide is known as the most important component of the lipid components that make up the stratum corneum, called the skin protective film to protect the skin. It is known to be excellent and provides the optimal environment for the skin to perform its optimal metabolic function.

Newly growing skin cells are present in the form of sugar spingo lipids with low ceramide content and mainly sugar linkages. However, when new skin cells reach the stratum corneum and reach the stratum corneum, the neutral ceramide in which sugar is dropped increases, forming a hydrophobic barrier of the stratum corneum.

Basically, ceramides have the role of lipid barriers to inhibit evaporation of water and maintain the structure of the stratum corneum. In the stratum corneum of the skin, keratinocytes are composed of a brick-like multilayer structure, and these keratinocytes are firmly bound by ceramide, cholesterol, and free fatty acids. Skin cells have a higher content of ceramides than other cells of the human body, and especially high amounts of non-polar neutral ceramides. This is a structural feature necessary to make up the skin's strong protective barrier.

In addition, since ceramide is decomposed into phytosphingosine on the surface of the skin, it acts as an antimicrobial barrier against harmful harmful microorganisms and plays an important role in controlling inflammation and wound healing. In many studies, ceramide has been found to be directly related to atopic dermatitis and other dermatological disorders. Ceramide and phytosphingosine have also been shown to be effective in treating atopic dermatitis.

Normally, ceramides present in the human body are classified into six types of ceramides 1 to 6 according to the degree of polarity, and in addition to these six kinds, cosmetics are used fermented ceramides and synthetic pseudo ceramides.

However, despite such characteristics, ceramide is difficult to contain more than 0.1% by weight due to the difficulty of stabilization, in order to contain a large amount of 0.1% by weight or more, as described in Korean Patent Publication No. 10-1999-066273 Since there are many usage restrictions, such as using ethanol or liquid crystal, the ceramide consumption in the market is mostly less than 0.1% by weight.

In addition, as the interest in herbal cosmetics increases, many researches and products about herbal extracts have been introduced as ingredients that improve skin, but most of them use materials such as Okyongdan and Danbang, which are said to be good for skin, which are introduced in Dongbobogam and Chinese medicine metabolism. Has been commercialized. In particular, the most preferred jade yongdan by each cosmetics manufacturer contains mung bean, hwahwahwa, white paper, hard bones, sculptors, etc., and it is used to expect various skin improvement effects such as skin trouble, skin whitening, blood circulation, and skin elasticity. Rather than systematic research results, it has been used mainly for introduction of literatures.

Recently, in the form of herbal cosmetics, mainly large corporations and oriental medical clinics, joint research-type products using professional medicine expertise of herbal medicines and formulation expertise of cosmetic technicians have emerged in connection with herbal medicine specialists and herbal hospitals. .

As a result, higher quality products are possible, and productization and branding that are comparable to imported overseas luxury goods are possible, and the market's trust and interest in oriental cosmetics are also increasing.

However, these herbal products are undeniable reality that there are bound to be limited to the development of a variety of products by developing a product to find the desired efficacy effect only with herbal or natural raw materials in order to maintain the unique image of the herbal.

Therefore, the present invention has been made in order to improve the conventional problems as described above, the purpose of the solubilization using a composite herbal ingredient and nano-stabilized ceramide that has been proven to reduce skin problems as a result of years of research to maximize efficacy And to prepare an emulsified cosmetics to provide a cosmetic composition containing herbal extracts and nano ceramides that are effective for skin moisturizing, elasticity as well as skin problems.

In order to achieve the above object, the present invention, 10 ~ 30% by weight of the aqueous composition containing at least 1 to 20% by weight of the composite herbal extract, 0.1 to 10.0% by weight of nano-stabilized nano ceramide, 1.0 to 80% by weight of purified water , Characterized in that the cosmetic composition containing a herbal extract and nano ceramide prepared by dissolving 10 to 40% by weight of the oil phase component at 60 to 80 ℃.

In addition, the nano ceramide of the present invention, 0.1 to 10% by weight of ceramide, 0.1 to 70% by weight of polyhydric alcohol, 1 to 10% by weight of lecithin, 0.1 to 10% by weight of alcohol, 0.1 to 80% by weight of purified water to a high pressure emulsifier It is preferable to use what was nanoized.

In addition, the ceramide of the present invention is any one selected from six kinds of ceramides 1 to 6, yeast ceramide, pseudo ceramide, and the complex herbal extract is preferably at least one selected from among the stamens of Ogapi, Pentachocho, Tsukyu-geun, Sewao, and Astronomical dong Do.

According to the herbal cosmetic composition of the present invention, as well as emulsified cosmetics, such as creams and lotions, when the solubilized product is manufactured and applied to the skin, there is an excellent effect not only moisturizing, elasticity but also improve skin troubles.

(Efficacy evaluation result)

1) Change in water retention

Principle: Measure the skin moisture by using the SKICON 200, which digitally displays the moisture content of the stratum corneum by measuring the electrical conductivity by applying an electrode with a built-in probe to the skin surface.

Sample: Control (purified water), Examples 1 to 3, Comparative Example 1

Method of measurement: Average after 5 measurements.

Result of measurement: Control

 Example 1 252% after 1 day 5% 263% moisture retention after 5 days

Example 2 218% moisture retention after 5 days 226% water retention

Example 3 160% after 1 day 5% after 168% moisture retention

Comparative Example 1: 80% moisture retention after 1 day 86% moisture retention improved

2) Antibacterial test

A staphylococcus aureus known as atopic dermatitis and dandruff were placed on the medium and checked after about a week. As a result, bacteria were not increased in Examples 1 to 3, but the antibacterial effect was confirmed. It was confirmed that there is no antibacterial effect due to the increase in the related bacteria.

3) human body skin test

Human skin test (Human Patch Test) to confirm the primary irritant of the product to be evaluated by the naked eye, the micro-stimulation 0.0 ~ 0.1, the intermediate stimulation 0.1 ~ 0.2, severe stimulation 0.2 or more When Example 1 was 0.0, Example 2 was 0.05, and Example 3 was 0.08, respectively, and the results were within the micro-stimulus range, and Comparative Example 1 was evaluated to 0.15, and the medial stimulation range was present.

From the evaluation results, Example 1 was found to be the best in all the water retention change, antibacterial activity test and human skin test, Comparative Example 1 was not improved in the antibacterial activity test and human skin test.

As described above, according to the cosmetic composition containing the herbal extract of the present invention and nano ceramide, the water content is prepared by containing 1 to 20% by weight of the composite herbal extract and 0.1 to 10.0% by weight of the nano ceramide in the aqueous phase and the oily component. As well as having an antimicrobial effect on pathogens that improve retention and cause skin troubles, cosmetics can be manufactured that can be used safely with little irritation when used on the skin.

In addition, the present invention, as the product of the combination of herbal extracts and nano ceramides can improve the skin continuously, suggesting a new direction of herbal cosmetics in the stable growth in the market and competition with imported luxury goods It is a useful invention that can have an advantage.
