Nowadays, many parents want to cultivate some hobbies and hobbies for their children. Many children like to paint their own, and they want their mom and dad to buy some highlighters for themselves. The pictures drawn will naturally glow at night, which is very Fun. However, which is better? Is the highlighter harmful to the body? The following small series will introduce you to everyone:
What is a highlighter? The highlighter is divided into two types, water and oil.
Water-based pens are similar to colored pens and are non-toxic, but not easy to dry. And the coverage is not good, the surface of some items can't be written, and the two colors will look dirty when stacked.
The oily pen is a synthetic solvent that dissolves in alcohol, and some sensitive people may smell dizzy when they smell it. But it is easy to write and easy to work with, coverage is good, and the price is cheaper.
The principle of a highlighter is to generate energy-level transitions of atoms by absorbing the energy of light, and then release the extra energy absorbed. Some fluorescent agents are added to the highlighter. Some fluorescent substances are toxic, have potential carcinogenic ingredients, are harmful to humans for long-term use, and are inexpensive. In order to reduce costs, some small workshops use toxic fluorescent agents as raw materials for highlighters. In addition, because the fluorescent pen contains a large amount of fluorescent agent, long-term use will seriously affect the child's vision.
In fact, as long as it is not used regularly, only occasional use, it will not be harmful. Which is better with a highlighter? Is it harmful to the body with a highlighter? I hope the above introduction can help everyone.
