Abstract

PURPOSE: To obtain an enamel remover having resistance to peeling off and removing power, keeping excellent gloss of nails and having a mild feeling by containing a methyl polycyclosiloxane. CONSTITUTION: This enamel remover is composed of 0.5-30wt.% of a methyl polycyclosiloxane of the formula ((n) is 4-9) as an active component, 98-65wt.% acetone and 2-25wt.% water, and as necessary, suitably composed of a lower alcohol, ethyl acetate, butyl acetate, ethylene carbonate, cellosolve, an oil component, humectant, an ultraviolet absorber, a fragrance, or a coloring matter, etc., are suitably incorporated. This enamel remover is prepared by adding the compound of the formula to acetone, and adding purified water after dissolved and sufficiently mixing.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an enamel remover.

[0002]

2. Description of the Related Art Heretofore, enamel removers have been used in which, in addition to acetone, ethyl acetate, etc., an oil content, a moisturizing agent, a surfactant, etc. are blended.

However, enamel which is strong against peeling (which is difficult to peel off when the enamel is applied again after using the remover) has a high ratio of acetone and has a strong effect of removing sebum and the like, and therefore has a glossy nail. It wasn't mild to the skin because it made the nails and its surroundings whitish. In addition, since some nails have a glossy appearance, some oils and moisturizers are mixed, but they are weak against peeling.

As described above, an enamel remover having both peeling resistance and mild feeling has not yet existed.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an enamel remover which is strong against peeling of enamel, has a removing power for enamel, and has a mild feeling such as keeping the gloss of nails good. I am trying.

[0006]

[Means for Solving the Problems] In view of the above situation, the inventors of the present invention have made diligent studies, and as a result, by blending methylpolycyclosiloxane, the composition has a strong resistance to enamel peeling and also has an enamel removing power. Moreover, they have found that the gloss of the nails is also kept good, and have completed the present invention.

That is, the present invention is characterized by being an enamel remover containing methyl polycyclosiloxane.

[0008]

The function of the present invention will be described below.

The enamel remover of the present invention is basically composed of methylpolycyclosiloxane, acetone and water.

The methylpolycyclosiloxane compounded in the enamel remover is octamethyltetracyclosiloxane to octadecamethylnonacyclosiloxane represented by the following general formula (I).

The amount of methylpolycyclosiloxane compounded is
0.5 Wt% to 30 Wt%, 5 Wt% to 20 W
t% is more preferable.

The amount of acetone is preferably 98 Wt% to 65 Wt% and the amount of water is preferably 2 Wt% to 25 Wt%.

It is also possible to mix lower alcohol, ethyl acetate, butyl acetate, ethylene carbonate, cellosolve, oil, moisturizer, ultraviolet absorber, fragrance, coloring material, etc. in the enamel remover within a range not impairing the features of the present invention. Is.

EXAMPLES Examples of the present invention will be described below. Of course, the present invention is not limited to these.

(Examples 1 to 5 and Comparative Examples 1 to 3) After adjusting the enamel remover with the composition shown in Table 1, tests were carried out for peeling resistance, enamel removing power and mild feeling depending on the panel. The compounding amounts are all Wt%. The manufacturing method and test method are as follows.

[Manufacturing Method] A predetermined amount of methylpolycyclosiloxane is added to a predetermined amount of acetone, dissolved and purified water is added, and a sample is obtained after sufficient mixing.

[Test method] -Panel: 10 housewives aged 25-30 years-Wet the enamel remover samples of the examples and comparative examples were moistened with a non-woven fabric, and the thumb and middle finger of the right hand coated with nail enamel, The little finger, the index finger of the left hand, and the ring finger are wiped alternately with the example sample and the other fingers with the comparative sample. -After 15 minutes, apply the same nail enamel to your nails.・ Test the test items after 3 days (do not restrain the behavior for 3 days).

[Evaluation Method] Strength against peeling The length of the portion peeled from the nail was measured with a caliper, and the total length was divided by 5 to obtain an average value. The average value was used to evaluate the strength against peeling. The evaluation criteria are shown below. Average value 1 mm or less ○ 1 mm to 2 mm △ 2 mm or more ×

Enamel Removing Power 3 ml of enamel remover was dipped in a non-woven fabric of 5 cm × 5 cm, and the nail enamel of each nail was scraped off with the same remover used on the first day to evaluate the removing power of enamel. The evaluation criteria are shown below. Rubbed until it completely falls 3 times or less ○ 5 times or less △ 5 times or more ×

Mild sensation to the skin (whiteness around the nail and the nail) The mild sensation to the skin was evaluated by the degree of whiteness around the nail and the nail after using the enamel remover. The evaluation criteria are shown below. When it does not turn white ○ When a slight whiteness is felt △ When it turns white overall ×

[0021]

[Table 1] As described above, the enamel remover according to the present invention was excellent in peeling resistance, enamel removing power, and mild feeling to the skin.

[0022]

Industrial Applicability According to the present invention, an enamel remover which is strong against peeling of enamel, has a removing power for enamel, and has a mild feeling such as maintaining good gloss of nails can be obtained.
