Description

Nail gel removal composition {NAIL GEL REMOVAL COMPOSITION}

The present invention relates to a gel-type nail gel removal composition and a nail gel removal method using the same.

In general, nail art is to decorate beautifully by forming various patterns on the hands and toenails, and mainly by applying a nail gel-based nail polish to the nails and curing them by irradiating light such as ultraviolet rays. Through this process, the nail gel is firmly coated like a glaze of porcelain, and has one of the most widely used nail makeup methods, having an excellent luster and lasting more than one month.

In general, nail art treatment using nail gel is a process of applying a base gel to the nails first and then applying a color gel and a top gel on the nails to protect the nails and increase the adhesion of the gel. After applying each gel, a curing process is performed to harden the gel.

Nail art completed through the above process has a solid firmness is not damaged in a general way, it is subjected to a process of removing using a gel remover (gel remover).

However, if the nail gel-based nail polish is thickly applied and hardened, unlike the existing enamel nail polish, the removal process is complicated, and it is difficult to erase by yourself. Therefore, the nail gel must be removed from a professional nail shop. Problems such as damage to the nail in the soak off process occurs.

The soak off process is to gently peel off the surface of the nail gel with a hand drill and wrap the nail with a special remover on the cotton, and wrap it outside with a foil to seal the remover so that it does not evaporate. After a complicated process, the plastic gel or wooden pusher is used to push and remove the remaining gel on the nail, which causes problems such as severely thinning or damage of the nail.

Experimental Example 1. Soak off effect experiment

The nail gel removal composition of the present invention is characterized in that it does not contain acetone, and compared the shock-off effect of the nail gel removal composition prepared using ethyl acetate or methyl acetate instead of acetone.

The experiment was performed on 30 adult males and females in their 20s and 40s, and was performed three times at three-day intervals.

Specifically, the experiments were performed on each of the eight fingers except for the thumb per person, gel gel of the same color (red) to all the subjects, and after filing the surface of the compositions of Examples 1 to 6 and Comparative Examples 1 and 2, respectively The extent to which the nail gel was removed after 20 minutes of treatment was evaluated.

The evaluation is a five-point scoring method, which is 5 points when 95% or more of the initial gel nail area is removed, 4 points when 85 to 95% is removed, 3 points when 75 to 85% is removed, and about 65 to 75%. Two points were given for removal, and one point for removal below 65%.

division Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 score 4.6 4.4 4.5 4.5 4.5 4.4 4.7 4.6

As shown in the above Table 1, the nail gel removal composition of the present invention has a wet-off effect similar to that of the nail gel removal composition prepared using acetone (Comparative Example 1) despite not containing any acetone. Furthermore, changing to ethyl acetate and methyl acetate from the results of the above Examples 1 to 3 did not give a big difference in the knock-off effect itself, and from the results of Examples 4 to 6, the natural-derived nail of the present invention. It was confirmed that even further addition of the protective composition had little or no effect on the knock-off effect.

Experimental Example 2. Skin and nail protection effect confirmation experiment

Since the conventional nail gel remover uses acetone, acetone is absorbed into the skin around the nail, causing aging and cracking of the skin, and problems such as thinning of the nail and cracking or damage.

The composition for removing nail gel of the present invention is characterized in that it does not contain acetone, and a skin and nail protection effect confirming experiment was conducted on the same personnel as the experiment of Experimental Example 1.

Specifically, the experiments were performed on 30 adult men and women in their 20s to 40s, and evaluated the degree of damage to the nails and the skin around the nails during a three-day nail gel procedure and a wet-off process every three days.

Evaluation is a five-point scoring method, the higher the satisfaction was to give a higher score, for example, if the nail weakening item is 5 points means that the nail is not weakened at all.

Among the evaluation items, “skin damage” refers to the general damage of the skin around the nail after treatment of the nail gel remover, swelling, itching, rash, and soreness. This refers to items related to all phenomena that occur when the nails are weakened, such as the decrease in hardness of nails felt by individual subjects and easily broken during daily life.

division Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Skin cracking 3.5 3.5 3.5 3.6 3.7 3.6 3.1 3.3 Dry skin 3.4 3.3 3.4 3.8 3.7 3.8 2.2 2.2 Skin damage 3.7 3.7 3.7 3.9 4.0 4.1 2.5 2.7 Fingernails 3.9 3.9 3.9 4.5 4.5 4.6 2.1 2.4 Nail weakening 4.0 4.1 4.1 4.7 4.8 4.8 1.9 2.5 Average 3.7 3.7 3.72 4.1 4.14 4.18 2.36 2.62

As shown in Table 2, Comparative Examples 1 and 2 containing acetone appeared to have a low score below average with respect to nails and skin damage, and in particular, it was confirmed that severe nail cracking and nail weakening occurred. However, Comparative Example 2, which additionally added the composition for protecting the nail, showed a significant improvement in the nail weakening items, etc., but it was confirmed that the overall score was still low (2.62). Examples 1 to 3 without using acetone Showed a high score of 3.7 points near normal to excellent, and the difference between ethyl acetate and methyl acetate was not significantly related to the degree of skin damage.

In Examples 4 to 6 to which the composition for additional protection of nails was further added, scores were increased in all items, and it was confirmed that the nails exhibited an excellent improvement effect on the weakening of the nails and the splitting of the nails.
