TECHNICAL FIELD
The present invention relates to a lip pack cosmetic composition for tattooing and a method of preparing the same. More particularly, the present invention relates to a lip pack cosmetic composition for tattooing and a method of preparing the same wherein a thin layer is formed by drying after spreading lips, lips from which the formed layer is removed are pigmented and a color may be maintained for a long time.
BACKGROUND ART
Cosmetics are classified into various types according to application parts, purposes of use, or constituting elements and types of products. For example, cosmetics may be classified into basic cosmetics (skin care cosmetics), makeup cosmetics (color cosmetics), body care cosmetics (body cleansing cosmetics), hair care cosmetics, cosmetics for a mouth, aromatic cosmetics and the like. Makeup cosmetics are used to make a beautiful skin color and to cover blemishes which are not covered with basic cosmetics by providing colors on a body such as a face, nails and the like after using basic cosmetics. Makeup cosmetics are classified into base makeup and point makeup. Base makeup is used to healthily and beautifully trim a skin uniformly by making a skin color of a full face and by covering blemishes such as stains, freckles and the like. Point makeup is used to naturally express individuality by partially emphasizing colors on lips, eyes, cheeks, nails or the like, or by providing a three-dimensional effect through shading. As point makeup, there are lipsticks, cheek blusher (rouge), eye shadow, eyeliners, nail polish and the like.
Among the point makeup, lipsticks are excellent cosmetics to express individuality. Lipsticks are used to provide color and gloss when applied to the lips. An additional purpose of lipsticks is to protect lips from cold, drying and the like. Generally, lipsticks are prepared into a soft stick having good elasticity by dispersing or dissolving color additives in an emulsion. In this case, as desired, fragrances, antioxidants, preservatives and the like may be added to lipsticks.
However, conventional lipsticks easily are smeared on foods or containers contacted with lips or removed and thereby lipsticks are continuously re-applied. In addition, when lipsticks are continuously re-applied, dead skin cells accumulate on lips and thereby lips looks messy. Accordingly, to solve the problems, Korean Patent Application Pub. No. 10-1996-0040344 (Lip Cosmetic Composition Having Persistence), Korean Patent No. 0152554 (Lip Cosmetic Composition), and Korean Patent Application Pub. No. 91-003078 (Lipstick Composition Not Smeared On Lips) proposed technologies to enhance persistency of lipsticks. However, prior technologies are not suitable for maintaining a color of a lipstick for 5 hours or more.
Recently, lip tattoo stickers providing a variety of colors and patterns on lips, and transient tattoo effects are popular. The lip tattoo stickers have superior persistency. However, the lip tattoo stickers are harmful to the human body due to adhesives used to provide a variety of colors on lips and, by using the lip tattoo stickers, lips may be easily dried.
Accordingly, inventors of the present invention studied about a lip pack cosmetic composition for tattooing which is harmless to the human body, and continuously provides a color on lips and, at the same time, sufficient moisture, thus completing the present invention.

DETAILED DESCRIPTION
EXAMPLES
Hereinafter, the present invention will be described in more detail with reference to the following Examples. The scope of the present invention is not limited to the following Examples and covers modifications of the technical spirit substantially equivalent thereto.
Example 1
Preparation of Lip Pack Cosmetic Composition for Tattooing
After inserting weighted allantoin, dipotassium glycyrrhizate, butylene glycol and distilled water into a container, the mixture was stirred until completely dissolved at 80° C. Subsequently, the resulting mixture was completely dissolved using a homogenizer at 3600 rpm and an Agi-homo mixer (AGI) at 26 rpm while slowly adding polyvinyl alcohol and then cooled at 45° C. Subsequently, a mixture of red color NO. 218 (CI45410:1), ethanol (alcohol), citric acid and a fragrance uniformly stirred was added thereto and then stirred using an Agi-homo mixer (AGI) at 26 rpm while cooling up to 30° C. As a result, a lip pack cosmetic composition was prepared.
Here, the prepared lip pack composition includes 0.05 wt % of allantoin, 0.03 wt % of dipotassium glycyrrhizate, 1.0 wt % of butylene glycol, 18.0 wt % of polyvinyl alcohol, 0.06 wt % of red color NO. 218 (CI45410:1), 3.5% of ethanol (alcohol), 0.35 wt % of citric acid, 0.1% of a fragrance, and 76.91 wt % of distilled water as a solvent.
Comparative Example 1
Preparation of Lip Pack Cosmetic Composition
A lip pack cosmetic composition was prepared in the same manner as in Example 1, except that citric acid was not used and distilled water was used in place of the citric acid in an equal amount.
Comparative Example 2
Preparation of Lip Cosmetic Composition
A lip cosmetic composition was prepared in the same manner as in Example 1, except that polyvinyl alcohol was not used and distilled water was used in place of the polyvinyl alcohol in an equal amount.
Experimental Example 1
Use of Lip Pack Cosmetic Composition for Tattooing
A lip pack cosmetic composition prepared according to Example 1 was spread along a lip shape in an amount of 0.1 to 0.2 g as a single dose. Subsequently, when the composition was completely dried after approximately 10 to 15 minutes, a formed layer was slowly removed from lips. Referring to FIGS. 1 and 2, after removing a dried and formed layer, lips were pigmented with an intrinsic color of the product according to the present invention. Therefore, it was confirmed that the lip cosmetic composition for tattooing prepared according to Example 1 may be used as a lip pack cosmetic composition for lip tattooing to provide transient tattoo effects.
Comparative Experimental Example 1
Use of Lip Pack Cosmetic Composition
A lip pack cosmetic composition prepared according to Comparative Example 1 was spread along a lip shape in an amount of 0.1 to 0.2 g as a single dose. Subsequently, when the composition was completely dried after approximately 10 to 15 minutes, a formed layer was slowly removed from lips. Referring to FIGS. 3 and 4, an intrinsic color of a product was not nearly pigmented on lips, from which a dried and formed layer was removed. Therefore, it was confirmed that the lip pack cosmetic composition prepared according to Comparative Example 1 is not suitable to provide transient tattoo effects.
Comparative Experimental Example 2
Use of Lip Cosmetic Composition
A lip cosmetic composition prepared according to Comparative Example 2 was spread along a lip shape in an amount of 0.1 to 0.2 g as a single dose. After spreading, approximately 10 to 15 minutes passed but a layer was not formed on lips. Therefore, it was confirmed that the lip cosmetic composition of Comparative Example 2 is not usable as a lip pack cosmetic composition.
Comparative Experimental Example 3
Use of Lip Tattoo Sticker
After cutting a commercially available lip tattoo sticker along the sizes and shapes of lips with a scissor, and removing a transparent film from the sticker, a paper portion of the sticker was sufficiently wet while tapping with wet cotton or a wet sponge such that a colored portion of the sticker was attached on lips. When the colored portion was attached to lips, the paper was removed from lips. It was confirmed that color elements were attached on lips after removing the paper.
Usage Example 1

Example 3









When the lip pack cosmetic composition for tattooing prepared according to Example 1 was spread on lips, a color pigmented on lips was maintained for 12 hours or more, showing excellent persistency. In addition, the lip pack cosmetic composition was not nearly smeared on food containers or foods. Furthermore, anybody may easily use the lip pack cosmetic composition since a formed layer is simply removed from lips after spreading and drying the lip pack cosmetic composition of a gel type on lips. By using the lip pack cosmetic composition, lip moisture was protected and a color pigmented on lips was naturally lost by general cleansing without separate cleansing as a certain time passed.
Meanwhile, when the lip tattoo sticker of Comparative Experimental Example 3 was applied to lips, a color pigmented on lips was maintained for 12 hours or more, showing excellent persistency. However, a use method of the sticker is very inconvenient in that the sticker is cut along the sizes and shapes of lips and, after attaching the sticker to the lips, the stick is tapped with wet cotton or a wet sponge. In addition, by using the stick, lips become dry in a short time and a separate cleansing step for color cosmetics is required to remove the pigmented color. Thus, preference for the stick was very low.
Overall, with the lip pack cosmetic composition for tattooing of the present invention, anybody may easily pigment a color on lips and express transient tattoo effects. At the same time, since lips may be moisturized, moist and glossy lips having a desired color may be expressed. In addition, to remove a color pigmented on lips, a separate cleansing step is not required and the color may be naturally lost when a certain time passed. Therefore, preference for the lip pack cosmetic composition for tattooing of the present invention will be very high.

At the same time, since lips may be moisturized, moist and glossy lips having a desired color may be expressed. In addition, to remove a color pigmented on lips, a separate cleansing step is not required and the color may be naturally lost when a certain time passed. Therefore, preference for the lip pack cosmetic composition for tattooing of the present invention will be very high.
