Background

The marking pen is one of the commonly used stationery, can write a pen for marking or marking, but is easy to draw on clothes when in use and is difficult to remove.

At present, the marking pen cleaning agent is used for dissolving polar and nonpolar parts in marking pen marks by using an organic solvent, so that the effect of removing the marks is achieved, meanwhile, the surface of an object cannot be damaged, and the marking pen cleaning agent is volatilized without residues. However, in order to achieve a good cleaning effect, the conventional marker pen cleaning agent mainly adopts solvents containing dichloromethane, toluene, acetone, ethyl acetate and the like with pungent odor, and the solvents have strong cleaning power, are extremely easy to volatilize and have great harm to human bodies. In daily use, a human body easily inhales volatile solvents, so that the body is uncomfortable, certain pollution is caused to the environment, and particularly, the influence on aquatic organisms and the atmosphere is more serious.
