Description

2nd cosmetic which show pH's range change to subacid by the color change and cosmetics using the same}

The present invention relates to a cosmetic for use on the skin, and more particularly, a cosmetic composition which can visually identify a weakly acidic cosmetic suitable for skin health by mixing a first agent containing anthocyanin and a second agent containing an organic acid, and It relates to cosmetics using the same.

The stratum corneum (SC) of the skin is present in the outermost layer of the skin and is an important part of the human body because it is in direct contact with the external environment.

The stratum corneum basically consists of keratinocytes and lipids between keratinocytes, and other epidermal lipids and natural moisturizing factor (NMF). At this time, keratinocytes are differentiated in the basal layer of the epidermis and are keratinized cells. The keratinocyte lipids are filled between keratinocytes and composed of lipid components such as ceramide, cholesterol, and fatty acids. Keratinocyte intercellular lipids form a lamellar liquid crystal structure and are responsible for the skin's flexibility, moisturizing and protective functions. The structure of these keratinocytes and lipids between keratinocytes can be explained by a two compartment model. The two compartment models are also referred to as brick and mortar models, compared to the mortar, which is the brick that builds the brick house and the bonding material between them. This unique structure exhibits a skin barrier function, a very important function of the skin. That is, it prevents the invasion of foreign substances from the outside, and at the same time as a barrier function to prevent the loss of the body moisture, electrolytes, etc. to the outside of the body, to maintain the moisture in the stratum corneum to give the skin elasticity, flexibility and moisture.

However, if the pH balance of the skin is broken, the activity of lipolytic enzymes is lowered, and harmful bacteria may proliferate, leading to a weakening of the skin barrier function. The weakening of the skin barrier function may be a major cause of various skin problems and chronic sensitive skin, dry skin and atopic skin.

 Although the pH of the skin varies from person to person, most of them have a weak acidity of 4.5 to 6.5, and more normal skin pH is 5.0 to 6.0. Maintaining weakly acidic pH as described above is an important factor for healthy skin. The reason is that lipases, which are involved in the synthesis of lipids that function as skin barriers in a weakly acidic environment, are activated, and the weakly acidic skin surface inhibits bacterial growth such as bacteria and prevents weakening of skin barrier function. Because. Therefore, it is required to maintain the pH of the skin weakly acid for healthy skin.

In order to maintain the pH of the skin weakly acidic cosmetics used on the skin should also be slightly acidic. Therefore, a lot of weak acid cosmetics are in circulation, but it is impossible for consumers to check them without using a pH meter.

Therefore, it is necessary to develop a cosmetic composition that can be discolored to a specific color when weakly acidic, so that the consumer can identify the slightly acidic cosmetics with the naked eye.

An object of the present invention is to provide a cosmetic composition exhibiting a reddish color when mixed with an anthocyanin-containing colorant and an organic acid when weakly acidic.

It is another object of the present invention to provide a cosmetic comprising a cosmetic composition.

 In order to achieve the above object, the cosmetic composition of the present invention is 80 to 91% by weight of the first agent containing 1 to 10% by weight of anthocyanin-containing colorant and 9 to 20% by weight of the second agent containing an organic acid .

The present invention also provides a variety of cosmetics such as creams, skins, gels, lotions, packs, cleansing creams, cleansing foams, cleansing water, cleansing oil or sunscreen creams by including a cosmetic composition.

In the cosmetic composition of the present invention, a first agent containing an anthocyanin-containing colorant and a second agent containing an organic acid are mixed to exhibit a specific color according to pH. Therefore, the cosmetics using the cosmetic composition of the present invention can be easily identified with the naked eye whether the acid (use of red color) useful for maintaining healthy skin. Therefore, the specific color appears according to the pH, so consumers can choose the weakly acidic cosmetics with confidence, and it can help the skin health of consumers because it can quickly check the deterioration of cosmetics for long-term use.

The present invention relates to a cosmetic composition and cosmetics using the same, which can be easily identified with the naked eye cosmetics useful for skin health by using a first agent containing an anthocyanin-containing colorant and a second agent containing an organic acid.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

The cosmetic composition of the present invention comprises a first agent containing an anthocyan-containing colorant and a second agent containing an organic acid.

At this time, the content of the first agent is 80 to 91% by weight, preferably 81 to 90% by weight, and the content of the second agent is 9 to 20% by weight, preferably 10 to 19% by weight. If the content of the first agent is less than 80% by weight, the content of the second agent is increased, so the pH may be excessively low, which may irritate the skin. If the content is more than 91% by weight, the content of the second agent is decreased. Cosmetic compositions that fall outside the weakly acidic range can be obtained. In other words, when the amount of the first agent and the second agent is too high, the amount of organic acid may be too low to cause irritation to the skin. When the amount of the first agent and the second agent is too low, the amount of the organic acid is too low. Cosmetic compositions that fall outside the weakly acidic range can be obtained.

The colorant included in the first agent contains anthocyanate so that the colorant can visually check whether the colorant is mixed with the organic acid of the second agent. Such a colorant is an extract extracted from the fruit and the leaf, it is preferable that the extract contains anthocyanin 0.01 to 30% by weight. When the anthocyanin content in the colorant is less than 0.01% by weight, it may not be possible to visually identify the pH state of the color change according to pH in the cosmetic composition. When the content is more than 30% by weight, the color may be dark due to a large amount of anthocyanin. This can leave a color on your skin.

The content of the colorant is 1 to 10% by weight, preferably 1 to 3% by weight. When the content of the colorant is less than 1% by weight, it may be slightly discolored by the organic acid of the second agent, so that it may be impossible to visually check the pH state of the cosmetic composition, and when the content is more than 10% by weight, the amount of anthocyanin may be increased. Due to the darker color, the color may appear on the skin.

The pH state means a state in which the cosmetic composition is acidic, neutral or alkaline.

Anthocyanin contained in the colorant is a natural water-soluble pigment appearing in a flower, fruit, leaf, etc. of plants, and refers to anthocyanins, which are pigment glycosides, and anthocyanidins, which are aglycones. Red, blue, and purple flowers, spring birds' eyes, and autumn leaves are due to anthocyan pigments. When the anthocyanin is dissolved in water, the color becomes red, and the more acidic, the more reddish it becomes. On the other hand, neutralizing a solution of anthocyanin with a weak alkaline solution turns purple, while neutralizing with a strong alkaline solution turns blue. The cosmetic composition therefore exhibits a specific color according to pH with an anthocyanin-containing colorant.

The first agent is one or two selected from the group consisting of purified water, metal ion sequestrants, pH adjusters, discoloration inhibitors, humectants, solubilizers, flavoring agents, preservatives, thickeners, emollients, moisture barriers, and emulsifiers, depending on the purpose, in addition to the colorant. 90 to 99% by weight or more of the additives may be included.

The organic acid included in the second agent discolors anthocyanin to confirm the pH state of the cosmetic composition of the present invention, as well as to adjust the pH of the cosmetic composition. The organic acid is one or two selected from the group consisting of citric acid, fumaric acid, succinic acid, succinic anhydride, adipic acid, aspartic acid, glutamic acid and maleic acid.

The second agent may include 98.00 to 99.95% by weight of one or two or more additives selected from the group consisting of purified water, metal ion sequestrants, pH adjusters, and preservatives, in addition to organic acids.

For example, the second agent of the cosmetic composition is 0.05 to 2.00 wt% of organic acid, 98.00 to 99.50 wt% of purified water, 0.01 to 0.10 wt% of metal ion sequestrant, 0.05 to 0.30 wt% of pH adjuster, and 0.10 to 2.00 wt% of preservative.

Thus, the cosmetic composition of the present invention consisting of a first agent containing an anthocyanin-containing colorant and a second agent containing an organic acid has a reddish color because the pH is 3.0 to 6.5 as weak acidity. The pH can be adjusted by the second agent.

Unlike the present invention, when the cosmetic composition is prepared in a one-component type containing a colorant and an organic acid, the color is changed to weak acidic while watching the color change, so it is preferable to prepare the two-component type containing the colorant and the organic acid, respectively.
