Description
TECHNICAL FIELD The present invention relates to a cosmetic composition and a hydrogel pack which change color according to pH change.
Conventionally, an artificial tar pigment prepared by synthesizing a petroleum component with a pigment used for imparting color to cosmetics to be produced has been mainly used.
However, as interest and understanding of cosmetics of consumers has increased, various researches have been conducted to use cosmetics using natural pigment extracted from natural materials that can replace artificial coloring matter.
Anthocyanin is a water-soluble substance that occurs in any plant such as leaf, stem, root, flower, and fruit of higher plants, but it is mainly present in fruits and flowers and exists in a large amount in the cell vacuole.
The anthocyanin is an flavonoid-based substance having little odor and taste, and can act as an antioxidant to remove reactive oxygen species.
Anthocyanin is a chromophore compound having pseudo benzene ring structures in which one or two of the carbons constituting the benzene ring and benzene are substituted with oxygen or nitrogen. In the benzene ring, a hydrogen atom is substituted with a hydroxyl group (OH - ), a carboxyl group COO -), a carbonyl group (CO -), sulfonyl group (that shows a combined structure variety of functional groups (functional group), such as SO 3 2-).
The above chromophore compound includes a so-called conjugated compound structure in which a double bond and a single bond are alternately linked to each other. The chromophore compound reacts with various functional groups of a chromophore molecule and a hydrogen ion (H + ) or hydroxide ion (OH - ) in an aqueous solution A new ring compound is formed or the length of a chain in which a single bond is alternately connected with a double bond existing in the molecule is changed so that the wavelength of the light absorbed by the chromophore molecule is changed even if only one kind of change occurs, The complementary color of the color corresponding to the wavelength is observed, so that the pH change in the solution can be visually confirmed.
Therefore, an aqueous solution containing anthocyanin is sensitive to changes in pH. A pH adjusting material may be added to change the aqueous solution to an alkaline state to form a blue-based color, or the aqueous solution may be changed to acidic It can be configured to show the color of the series, and it can be utilized in various fields by using such characteristics.
However, the technical content of cosmetic materials excellent in skin improvement effects such as antioxidant activity, anti-aging, anti-aging, wrinkle improvement, whitening, etc., has not been disclosed using anthocyanin, which is a natural material, Do.

Fig. 2 is an actual image of the color change caused by pH change of the cosmetic composition according to Example 1. Fig.
3 is an actual image of a hydrogel pack prepared according to Example 2. Fig.
4 is an actual image of the color change observed after attaching the hydrogel pack prepared according to Example 2 to the user.
The present invention provides a cosmetic composition comprising a plant-derived anthocyanin extract and having a color change by pH change.
The anthocyanin is a kind of polyphenol which is a strong natural antioxidant and has various physiologically active functions such as prevention and improvement of vascular diseases, anti-inflammation and antibacterial, anti-aging, wrinkle improvement, whitening or stimulation of insulin production. So that the cosmetic composition can be configured to directly and indirectly exhibit such useful effects as described above.
The cosmetic composition for color change according to the above-mentioned pH change may include anthocyanin extract extracted from a variety of colored fruits, flowers, curds or plant roots containing a large amount of anthocyanin, and preferably an aroma extract of a purple cabbage, , Anthocyanin extracted from a single plant or a mixture thereof extracted from natural plant material such as black rice, purple sweet potato, black corn, morning glory, petunia, assai berry, aronia, raspberry, eggplant, red grapes or carrot.

In addition, the color change cosmetic composition according to the present invention may be configured to contain a pH adjusting agent at a certain concentration, thereby forming a color change cosmetic composition suitable for the purpose of use.
For example, an acidic pH adjusting agent may be added to a cosmetic composition containing an anthocyanin extract so that the cosmetic composition may have a purple or red color tone. The cosmetic composition may be atopic skin or acne skin The color of the cosmetic composition is changed to blue or cyan based on the pH due to the influence of the pH of the skin, and at the same time, the pH of the cosmetic composition is brought close to the pH of the healthy skin by the pH of the cosmetic composition It is possible to induce control of the user's skin pH.
However, in the above-mentioned case, when the cosmetic composition is excessively acidic, the skin barrier may be lost to lose the balance of sebum secretion and water content, and adverse effects such as sebum secretion may occur. Therefore, It is preferable to add the pH adjusting agent only to such a concentration that the pH of the solution does not become less than 5.
Alternatively, an alkaline pH adjusting agent may be added to a cosmetic composition containing an anthocyanin extract so that the color-changing cosmetic composition may have a blue or blue-based color, and the cosmetic composition may be a composition containing sebum, lactic acid, The color of the color change cosmetic composition is changed into a purple color by the pH due to the influence of the pH of the skin, and at the same time, the pH of the user's skin is changed by the pH of the color change cosmetic composition It is possible to induce the control of the user's skin pH to be close to the pH of the healthy skin.
Therefore, it is possible to constitute the color-changing cosmetic composition so as to control the color of the color-change cosmetic composition itself by adding the pH adjusting agent as described above, and it is possible not only to form a color-changing cosmetic composition having various pH ranges for the purpose of use, The color change of the color change cosmetic composition can be visually confirmed and can be effectively used for skin care.
