Can painting on the skin with a gel pen hurt the skin?

It won't hurt the skin if it is painted on the skin with a gel pen, because in the development of the formula, it is necessary to ensure that the ink is safe, non-toxic and non-corrosive. Therefore, the ink with such characteristics has a good guarantee in terms of safety, a certain guarantee for human health, and no harm to skin.

Gel pen originated in Japan and is a novel writing tool that is popular all over the world. According to the type of pen, the color and structure of ink, it can be divided into different types of gel pens.

Other characteristics of gel pen:

(1) ink has a strong versatility, which can not only match the pen tip more widely, but also achieve better writing performance, thus becoming a supporting product of the pen factory.

(2) It is required that the ink should have corresponding false shrinkage and viscosity stamp, and the intermittent performance of the ink should be long, so as to achieve a longer uncapping time.

(3) The ink should reach a certain particle fineness, which is lower than the clearance between the ball and the ball seat, and has strong dispersion ability to prevent the pen from blocking writing.

(4) The ink has strong stability, can write normally at a certain room temperature, and the ink is even and not layered.

(5) There is enough writing length, that is, a tube of ink can draw a longer line on the scribing machine.

Matters needing attention in gel pen production:

The particle size of color-based pigment used in neutral ink must be extremely fine, and raw materials close to nanometer level (such as high-quality acetylene carbon black) should be used. The used color-based dyes and auxiliary materials must be completely miscible to avoid the formation of bubbles and particle aggregates, and full attention must be paid to the selection of raw materials. In the processing technology, mainly solve the grinding process, ensure the fineness of particles, do not block, do not cause water.
