Camphor and Stinky Balls

In the summer, many people put camphor or stink balls (sanitary balls) in their wardrobes to prevent them from being eaten by insects. In fact, camphor and stink pills are different in nature. If we use them inappropriately, the opposite effect may occur. So here, I want to talk about camphor and stink pills.

Camphor is a ketone, and its molecular formula is C10H16O. It is a crystal obtained from natural camphor wood. Its special fragrance is sublimated from the crystals and can be used in medicine and to prevent insect erosion. Just because it is non-toxic and has no harmful effects on the human body or clothes, camphor is safe to use.

Stinky pills are made from naphthalene, which is a condensed aromatic hydrocarbon compound extracted from crude oil or coal tar. The "stinky" gas it sublimates is toxic, especially damaging to the liver. It also reacts chemically to silk and nylon, so some holes will appear in these garments. When we use stink pills, it is enough to use 1-2 balls. Remember to wrap these stink pills with cloth to avoid direct contact between the stink pills and clothes.

Therefore, using camphor is safer than using stink pills. But in terms of price, camphor is more expensive than stinky pills.
