If the basic malachite green quality you bought does not meet the standard, it may be easy to fade or not easy to color. This is mainly because the color of the dyes themselves is not pure or contains other impurities. On the other hand, for the production of basic malachite green, because some of the materials used by the manufacturer are inferior, naturally it will not meet the good requirements of its products, so for its materials, on the one hand, it will reduce the performance of its products, and on the other hand, it will effect environmentally friendly. Of course, for the use of this product, users are to make it good durability, because some products can be used, but after a period of time, it began to fade.
