Description

Composition for coating nail

The present invention relates to a composition for nail coating, and in detail, after applying nail enamel to the imprinted image plate, in particular, after nail art, a silicone stamp is applied to the silicone stamp, and then stamped on the nail to the image plate. After the so-called "stamping nail art" [brand name of Conard Co., Ltd.] to draw the engraved pattern of the nail, the nail enamel drawn on the nail is prevented from spreading and the gloss is given to provide excellent durability and good adhesion. It relates to a nail coating composition to have a.

In general, in order to prepare a dispersion type nail coating agent, nitrocellulose is usually used as a primary film former for imparting coating power, and toluene sulfonamide / secondary secondary film former is usually used. Formaldehyde resins, phthalic anhydride / trimelitic anhydride / glycol copolymer copolymers, ketone resins, and the like are used to enhance the bond between particles.

In addition, to improve the elasticity and flexibility, plasticizer (Plasticizer) is used dibutyl phthalate, acetyl tributyl citrate, triphenyl phosphate, dibutoxy ethyl phthalate, camphor, casteoyl and the like.

In order to disperse film former and nonvolatile components and to control evaporation rate, flowability and viscosity of nail enamel, esters such as ethyl acetate and butylacetate are used as active solvents. The purpose is to form a beautiful appearance by dispersing and dissolving alcohol with diluent using toluene, xylene, etc. as a coupler, and persisting the color that appears after applying to nails, and enhancing gloss and wear resistance. It is a conventional kind of transparent coating agent.

However, the general nail coating formulations have satisfactory physical properties such as gloss, abrasion resistance, and drying speed, but after nail art, in particular, after applying nail enamel to an engraved image plate, a silicone stamp is applied to the silicone stamp and then transferred to the nail. When stamping on the nail again to make the engraved pattern of the image plate on the nail, so-called "stamping nail art" (trade name of Conard Co., Ltd.) and then applying a nail coating on it, It has the biggest problem, such as the lack of bleeding prevention and collar bleeding prevention. This goes beyond the idea that stamping nail art is developed so that anyone can enjoy nail art anytime, anywhere.

On the other hand, recently, problems such as yellowing, nail crumbs due to deoiling of nail material and transmission of skin allergy around nails are known due to excessive physical and chemical irritation and stress caused by frequent use of nail enamel, malnutrition, etc. Consumers' interest in health is increasing.

Toluene, formaldehyde resin, debutyl phthalate, etc., which have been used for a long time as a main ingredient, are mentioned as the above-mentioned causative agents, and these substances are mentioned as environmental hormone substances such as carcinogenicity and endocrine disruption as well as nail damage. Research on environmentally friendly nail enamels and nail coatings has been actively conducted.

Korean Patent Registration No. 10-0118766 contains a coating composition of suspected environmental hormones such as toluene sulfonamide / formaldehyde resin and dibutyl phthalate containing formaldehyde and is excluded from eco-friendly nail enamel, especially after stamping nail art The bleeding and collar bleeding of the deep sea are undesirable for application as a stamping coating.

Accordingly, the problem to be solved by the present invention is to solve the problems described above to provide a composition for nail coating suitable for use after nail art, in particular after stamping nail art.

Nail plate is combined with acrylic polymer powder to form SN linear structure of similar protein of keratin (Keratin) to control the thixotropy of the nail art pattern during application, so that the pattern is uniformly arranged by adhesion and instant drying The present invention has been completed in view of the fact that it is possible to prevent bleeding even if it is applied immediately. In addition, the present inventors further dissolve and disperse a powder containing at least one selected from the group consisting of organic silicone resins, polyester resins, keratin liquids, in addition to acrylic polymer powders in order to express a clearer image after nail art. It has been found that the inclusion can more effectively solve the problems of the prior art.
