Description

  The present invention relates to a nail decoration base gel composition for improving durability against peeling of a nail decoration provided on a nail from the nail.

Conventionally, as a method for decorating nails in a nail salon, first, in order to eliminate unevenness on the nail surface and make it a smooth surface, a viscous and fluid photocurable base gel composition is applied to the nail. After coating, a base layer is formed by irradiating light such as ultraviolet rays or visible light, and a viscous and photo-curable decorative color gel is applied on the base layer. Thus, after the additional decoration treatment, a method of forming a decoration layer by curing by photopolymerization in the same manner as the base layer is widely performed.
Conventionally, before applying this photocurable base gel composition, dirt and oil on the surface of the nail are removed, so that the base layer and decorative layer formed thereafter are difficult to peel off from the nail. ing. In particular, in the nail art field, it has been considered that it is very undesirable for oil to remain on the nail surface in order to prevent peeling. Therefore, when applying nail art, first, the nail surface is treated with alcohol to remove oil.
Conventionally, with such an understanding, the coating agent that comes into contact with the nail has an oil content in the coating agent in order to suppress peeling between the nail and the coating layer formed from the coating agent. It was considered important not to include. This is because if the coating agent contains an oil component, if it is applied to the nail surface, the oil component oozes out from the coating agent and is considered to be the same as the presence of the oil component on the nail surface. On the other hand, about the fact that the decorative layer formed on the nail surface from the nail surface is effectively protected from floating and peeling by actively mixing oil in the coating agent in contact with the nail. It has never been known before.
By the way, conventionally, a base gel composition containing oily vitamin E (tocopherol) is known as a Sacura base gel. However, since vitamin E has a brown coloration, addition of a very small amount (for example, up to 1%) has been recommended in order to maintain the non-coloring property of the base gel composition. Further, it has been found that this level of addition does not have any base layer peeling prevention function.

  In the case of decorating the nail, the present invention makes it difficult for the base layer formed from the base gel composition to be applied to the nail surface and the decorative layer formed thereon to peel off from the nail surface. An object of the present invention is to provide a nail decoration base gel composition for improving durability of a layer and a decoration layer.

Based on the idea in a direction contrary to the conventional concept, the present inventors dare to include aroma oil in the photocurable base gel composition applied to the nail surface, thereby making it possible to Compared with the base gel composition which does not contain an aroma oil, it turned out that the float and peeling of the base layer derived from a base gel composition improve unexpectedly and significantly. As a result, it has been found that peeling of the decorative layer formed on the base layer is prevented as a whole, and long-term use is possible.
The present invention has arrived at the present invention by adopting such a technical configuration contrary to conventional common sense.

That is, the present invention is a photocurable base gel composition, which is a group consisting of aroma oils, in particular, frankincense, rosewood, ylang ylang, geranium, lavender and teatoly, compared to conventional base gel compositions. The above-mentioned problems are solved by adding an aroma oil selected from 5 to 7% (volume). In the present invention, for example, in the form of a kit, an aroma oil may be separately prepared in advance by a predetermined blending, and blended into a base gel before performing nail decoration.
That is, the present invention relates to the following inventions.
1. A photocurable base gel composition, characterized in that the aroma oil is added in an amount (volume) of 5-7%;
2. 2. The base gel composition according to 1 above, wherein the aroma oil is selected from the group consisting of frankincense, rosewood, ylang-ylang, geranium, lavender and teatouri.
3. A method for preparing a base gel composition, comprising adding aroma oil in an amount (volume) of 5 to 7% to the base gel composition;
4). 4. The method according to 3 above, wherein the aroma oil is selected from the group consisting of frankincense, rosewood, ylang-ylang, geranium, lavender and teatouri; A nail decoration method using the photocurable base gel composition according to 1 or 2, wherein the base gel composition is applied to the surface of a nail and photocured,
6). An aroma oil blended in a nail decoration base gel composition, wherein the aroma oil is added in an amount (volume) of 5 to 7% with respect to the nail decoration base gel composition.

  Hereinafter, the present invention will be described in more detail with reference to specific examples. However, the following examples are illustrative of the present invention, and the scope of the present invention is not limited by these examples. It should be specified.

Example 1 (Photocurable Base Gel Composition and Nail Decoration Using the Same)
For each 1ml of New Sacra Gel, Biosculpture Clear Gel, Bio Gel, T-Gel (Base Gel), and NB Base Gel HD, 1 drop (0) of Frankincense, Rosewood, Ylang Ylang, Geranium, Lavender or Tea Toe 0.5 ml) was added.
Below, it demonstrates centering on the example of the decoration which uses the base gel composition (base gel composition A) which mix | blended frankincense as aroma oil with respect to New Sacra gel. Similar effects were obtained with other base gel compositions to which other aroma oils were added.

Decoration Method 1 Pretreatment The nail surface was cleaned with disinfecting ethanol. Next, the nail surface was polished with a spear (for example, 180 G), trimmed, and the nail surface was sterilized and dried with cotton containing a disinfectant.
2 Application of Base Gel Composition Base gel composition A was uniformly applied onto a pretreated nail with a brush, and cured by irradiation with UV light for 2 minutes and LED light for 30 seconds.
3. Formation of decorative layer On the base layer formed from the base gel composition A, a Sacra color gel is uniformly applied as a color gel with a brush and irradiated with UV light for 2 minutes (or with LED light for 30 seconds). And cured. If necessary, other decorations were fixed with clear gel.
4 Finish Apply top gel uniformly, irradiate with UV light for 2 minutes (or 30 seconds with LED light) to cure, and wipe uncured gel with cotton containing bactericides (various cleansers).
Similarly, the type of the base gel composition was changed. Moreover, durability was evaluated using the base gel composition which does not mix | blend aroma oil.

Durability confirmation test Panelists were decorated as described above, and the state of nails was observed after 2 weeks, 3 weeks and 4 weeks.
Ten points were given to one person in advance, the state of the nail decoration after each period was evaluated, and the points were deducted from 10 points based on the following criteria.

0 point: No peeling or floating.
-0.3 point: Slight floating was observed.
-0.5 point: About half of the float was observed.
(Survey period: July 1, 2013 to the end of May 2014)

Example 2
In this example, geranium is blended as an aroma oil with New Sacra gel. As a comparative example, a comparison was made with the nail decoration performed in the same manner except that no aroma oil was added.
When the aroma oil was blended, the durability after 3 weeks was 9.3. On the other hand, it was 7.0 when the aroma oil was not blended.
Moreover, when geranium was blended as an aroma oil in the Sacra base gel, the durability after 3 weeks was 8.4. On the other hand, it was 7.0 when the aroma oil was not blended.
Further, when geranium was blended as an aroma oil with T-gel (base gel), the durability after 3 weeks was 8.4. On the other hand, it was 7.4 when no aroma oil was blended.
Moreover, when geranium was blended as an aroma oil with biosculpture clear gel, the durability after 3 weeks was 9.3. On the other hand, it was 7.7 when no aroma oil was blended.
From the above results, it can be seen that when the aroma oil is added to the base gel composition, the degree of durability after, for example, 3 weeks is significantly improved as compared with the case where the aroma oil is not added.
