Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin paint suitable for face paint, body paint, makeup and the like.

[0002]

2. Description of the Related Art Commercially available skin paints include water-based paints for makeup and oil paints using color inks used as surgical markings. These are body paints for drawing various designs on arms, for example. Or, a supporter who supports a soccer team, or a spectator who watches a soccer game, is used for face paint to draw the flag of the cheering team, the national flag, etc. on its face.

[0003]

However, the water-based paint for makeup is applied to the surface of the skin such as the face or arm with a fingertip or a cotton swab to draw a desired pattern and then dried at body temperature. When it gets wet, the design drawn with the paint may bleed or have a color mixture, or the paint may run off, the shape of the design may collapse, or the design may disappear.

Furthermore, there is a risk that paint that has run off due to rain or sweat may adhere to clothes and stain the clothes. Further, in order to remove the paint from the skin surface after use, it has been troublesome to wash it with water or wipe it with a cloth or wet tissue moistened with water.

On the other hand, oil-based paints using ink used for surgical marking have the advantage that they do not run off due to rain or sweat during use, but on the other hand, they are removed with soap or cleansing foam after use. There was the trouble of having to do it. In addition, the ink used for surgical marking may cause allergic itch and rash when applied to the skin.

Therefore, according to the present invention, even if it gets wet with rain or sweat during use, there is no bleeding or color mixing, and there is no risk of it getting wet and falling with rain or sweat.
It is a technical problem to provide a skin paint that can be easily and cleanly removed without washing with water or using soap or cleansing foam.

[0007]

In order to solve the above problems, the skin paint according to the present invention is a rubber latex which is applied to human skin to form a peelable rubber film on the skin surface. It is characterized by comprising a thickening agent for thickening the rubber latex to such an extent that it does not sag when applied to the skin, and a pigment for coloring the skin.

Since this skin paint has such a viscosity that it does not sag when applied to human skin, a desired pattern can be drawn on the skin surface with a fingertip or a cotton swab. Further, when dried, it becomes a rubber film adhered to the skin surface, so there is no risk of it getting wet with rain or sweat and causing bleeding, color mixing, or runoff. After use, it can be easily and cleanly removed from the skin surface simply by pinching the end of the rubber film attached to the skin surface with a fingertip and peeling it off.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. The skin paint according to the present invention is mainly composed of a rubber latex which is applied to human skin to form a peelable rubber film on the skin surface, and when the rubber latex is applied to the skin, sagging It contains a thickener that thickens to the extent that does not occur, and a pigment for coloring the skin.

As the rubber latex, a natural latex which is easy on the skin is preferable, and in particular, a deproteinized latex obtained by removing a protein which is a causative substance of immediate type allergy from a natural rubber component is a safe substance registered as cosmetics. Since it can be used safely by people with sensitive skin, it is ideal for skin paints.

As the thickener, hydroxypropylmethylcellulose, which is also a safe substance registered as a cosmetic and has good compatibility with natural latex, is most suitable.

Further, as the pigment, it is preferable to use an inorganic pigment such as an organic pigment registered as a cosmetic or a ceramic color powder.

The optimum embodiment is 100% deproteinized latex (“SELATEX” manufactured by Sumitomo Rubber Industries, Ltd.).
5 to 10 parts by weight of a thickening agent, hydroxypropylmethylcellulose (“Metroze 10% solution”, manufactured by Shin-Etsu Chemical Co., Ltd.), was added to the parts by weight. Is excellent.

That is, the deproteinized latex and the thickening agent hydroxypropylmethylcellulose are both safe substances registered as cosmetics and are unlikely to cause allergies even when applied to the skin.

Further, the paint in which the deproteinized latex and the thickener are blended in the above-mentioned ratio is
It was confirmed by experiments that it can be smoothly extended with a fingertip or a cotton swab without causing sagging, so that a desired pattern can be drawn on the skin surface.

The paint having the above blending ratio is dried about 2 minutes after being applied to the skin to form a rubber film firmly attached to the skin surface. Moreover, this rubber film has elasticity and toughness that does not break even if you pull it from the skin surface by picking the end with your fingertips, so you can quickly peel it off the skin surface and remove it easily and cleanly. can do.

If the content of the thickener is less than the above 5 parts by weight, the fluidity of the rubber latex will increase, and when it is applied to the skin, it will tend to sag. It causes a problem that drawing becomes difficult.

If the blending amount of the thickener is more than 10 parts by weight, the viscosity becomes excessive and it becomes difficult to smoothly spread the paint applied to the skin on the skin surface with a fingertip or the like. However, the drying speed of the paint also increases, causing the problem that the pattern can not be drawn as you want, and at the same time, the rubber film formed on the skin surface becomes brittle and easy to tear, so pick the end with your fingertips There is a problem that it cannot be peeled off from the surface as a film.

Next, as a pigment for coloring the skin, an organic pigment which is also registered as a cosmetic (“WS series” manufactured by Toyo Ink Co., Ltd.) is used, and the mixing ratio varies depending on the color and material of each pigment. The range in which the coloring can be applied to the skin such that the background cannot be seen through when applied to the skin is about 2 to 20 parts by weight with respect to 100 parts by weight of the deproteinized latex.

Ammonia is added to the deproteinized latex as a preservative. In addition, in order to eliminate the ammonia odor, the deproteinized latex was heated to 50 ° C.
A heating treatment is carried out by heating and stirring for 24 hours.
Therefore, there is no possibility of producing an irritating odor or an unpleasant odor when the makeup paint is applied to the face.

The above is an example of the skin paint according to the present invention. Next, the method of use and the effect thereof will be described.

The skin paint according to the present invention is filled in a tube with a lid having good airtightness for each color, for example, as in the case of general watercolor paint or oil paint, and the mouth of each tube is put on the tip of a finger or a cotton swab. Use by squeezing an appropriate amount.

Then, the paint squeezed out on the fingertip is directly applied to the skin with the fingertip so that the desired pattern can be drawn quickly while being spread on the skin surface. The paint thus applied to the skin is dried at body temperature to form a peelable rubber film attached to the skin surface. Since the rubber film has water resistance, even if it gets wet with rain or sweat, There is no risk of color mixing or bleeding of the pigment, and there is no risk of runoff due to rain or sweat. Therefore, the shape of the design drawn with the paint does not collapse, the design does not disappear, and at the same time, there is no risk of soiling clothes or the like.

[0024] In addition, since the paint that is adhered to the skin surface as a rubber film can be easily and cleanly peeled off from the skin surface by pinching the end of the rubber film with a fingertip,
There is no need to wash it off with water or detergent after use.

[0025]

As described above, since the skin paint according to the present invention hardly causes sagging when applied to the skin, a desired pattern can be drawn on the skin surface. Also, when it is applied to the skin and dried, it forms a rubber film that is water resistant, so the design drawn with that paint will get wet with rain or sweat and cause bleeding or color mixing, or it will run off due to rain or sweat and form. There is no danger that the Furthermore, after use, it can be easily and cleanly removed simply by pinching the end of the rubber film attached to the skin surface with a fingertip and peeling it off.
