BACKGROUND OF THE PRESENT INVENTION


FIELD OF INVENTION



[0003] The present invention relates to a gel nail polish, and more particularly to an easily wipeable gel nail polish and its manufacturing and using method, wherein the gel nail polish is dried out easily and can be directly wipe off by the polish remover without a complicate removing process.

DESCRIPTION OF RELATED ARTS



[0004] Gel nail polish is relative new in the market but has become really popular at nail salons and for nail painting enthusiasts in a short time. One of the popular gel nail polishes is soft gel polish, which is often called as a soak off gel polish. The current soak off gel polish is long-lasting after applying on the nails, and always looks as new, wherein the soak off gel nails last on the nails for about 2 to 3 weeks without chipping, and they always look like they are just done. In addition, the soak off gel polish can be easily and directly painted on the natural nails in order to do the nail extension, and the user can easily change the color of the soak off gel nails by directly applying the traditional nail polish on the soak off gel nails.

[0005] Accordingly, the users need to initially apply the soak off base coat nail polish on their nails as a first layer, and then apply at least one layer of soak off gel nail polish thereon as a second or third layer. Accordingly, the users need to apply a top coat nail polish on the third or fourth layer. In particular, in order to dry each layer on the nail, the nail must be exposed under a LED light or a UV light. In other words, each layer cannot be dried under the sunlight, so that it is inconvenience and money-wasting for the users to prepare and purchase the LED light or the UV light device. In addition, after each layer is dried, some wet sticky colloids will residue on the layer, so that the users must use alcohol to remove wet sticky colloids on each layer and to polish each layer after the following layer is applied. Therefore, the users need to spend at least 60 minutes to finish the four layers soak off gel polish structure, including the soak off gel nail polish applying time, drying time, and residue removing time.

[0006] Furthermore, the removing process of the soak off gel nails is inconvenience and troublesome. Since the structure of the soak off gel polish layer is hard (having at least three-layered structure), the user's soak off gel nails cannot be directly wiped off by using a rag, cotton, or tissue paper with the nail polish remover, so the user needs to saturate a piece of cotton ball in the nail polish remover and place it on each of the nails until the cotton makes contact with the entire nail surface, and uses the aluminum foil to wrap around the fingertips until the cotton balls firmly attach on the nails. Waiting for 5 to 7 minutes, a gap will naturally generate between each of the nails and the soak off gel polish layer thereof, and then the user can use cuticle pusher or iron pusher to pop the soak off gel polish layer off the nail. Accordingly, after the soak off gel polish layer is removed from each of the nails, some residue gel is residued on the nail, so that the user must use the nail file or nail buffer to completely remove the residue gel from the nail. For such removing process, the user has to spend at least 30 minutes to remove the soak off nail polish layer from their nails, and the nails will be damaged and thinned by frequently using the nail file or nail buffer.

  5. (E) Apply a coat of gel nail polish top coat on the gel nail polish layer to form a top coat layer.
  6. (F) Dry the gel nail polish top coat to form a finished gel nail polish structure, wherein when the gel nail polish top coat is dried, no wet sticky colloid is formed on the finished gel nail polish structure.
    The wipe off base coat layer, the gel nail polish layer and the top coat layer are completely dried, for example, under an exposure of LED light for 30 to 60 seconds, under an exposure of UV light for 2 minutes, or under an exposure of sunlight for 1 to 2 minutes. It is worth mentioning that there is no wet sticky colloid formed on the finished gel nail polish structure, such that the user does not need to use alcohol to remove wet sticky colloids on the finished gel nail polish structure formed by the conventional soak off gel nail polish.
    If necessary, repeat the steps (D) and (E) to apply a second color coat of gel nail polish on the nail. The second coat is applied on the first gel nail polish layer after the first gel nail polish layer is dried. The second coat is dried under an exposure of light to integrally form the second layer on the first gel nail polish layer as one single layer structure. It is worth mentioning that the finished gel nail polish structure is three-layered or four-layered gel nail polish, which is determined by the number of color gel nail polish layer applied on the nails.
  7. (G) When removing the gel nail polish layer, the user may simply directly wipe off the finished gel nail polish structure by a rag, cotton, or tissue paper soaked with the nail polish remover. It is worth mentioning that the finished gel nail polish structure can be kept on the nail for as long as 7 to 14 days as it is originally applied thereon.

And, the user doesn't need to use cuticle pusher or iron pusher to pop the gel nail polish layer off the nail, so as to prevent the nails being uneven and not smooth. In addition, the user also doesn't need to nail file or nail buffer to completely remove the residue gel from the nail, so as to prevent the nails being thinner. In other words, the removing process of the gel nail polish of the present invention can dramatically reduce the damage happened on the nails as by the conventional way.

[0031] It is worth mentioning that the conventional gel nail polish cannot be dried by simply exposing under the natural sunlight. And, after the top coat layer is dried, some wet sticky colloids will residue on the layer, so that the users must use alcohol to remove the wet sticky colloids on the gel nail polish layer. Therefore, the gel nail polish of the present invention allows the user to save much time and money to apply and remove the gel nail polish on their nails.

[0032] Referring to Fig. 3 of the drawings, the present invention further provides an alternative mode of a method of using the gel nail polish, wherein the using method comprises the following steps:
  1. (A) Apply a color coat of gel nail polish on the nail. The user is able to apply a color coat of gel nail polish from the gel nail polish bottle via a conventional method. It is worth mentioning that no base coat and top coat is required before and after the gel nail polish layer is formed on the nail.
  2. (B) Dry the color coat of the gel nail polish under an exposure of light to form the gel nail polish layer, wherein when the gel nail polish layer is dried, no wet sticky colloid is formed on the gel nail polish layer. The gel nail polish layer is completely dried, for example, under an exposure of LED light for 30 to 60 seconds, under an exposure of UV light for 2 mintues, or under an exposure of sunlight for 1 to 2 mintues. It is worth mentioning that there is no no wet sticky colloid formed on the gel nail polish layer, such that the user does not need to use alcohol to remove wet sticky colloids on the gel nail polish layer formed by the conventional nail polish.
    If necessary, repeat the steps (A) and (B) to apply a second color coat of gel nail polish on the nail. The second color coat is applied on the first gel nail polish layer after the first gel nail polish layer is dried. The second coat is also dried under an exposure of light to integrally form the second layer on the first gel nail polish layer as one single layer structure. The double layered gel nail polish is opaque and makes the color more intense and even on the nail.
  3. (C) To remove the gel nail polish layer, directly wipe off the gel nail polish layer by a rag, cotton, or tissue paper with the nail polish remover. It is worth mentioning that the gel nail polish layer can be kept on the nail for 7 to 14 days as new as it is originally applied thereon.


[0033] One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
