樟腦丸有天然樟腦丸與合成樟腦丸之分。是一種有機化合物，含有萘的樟腦丸大多呈白色，氣味刺鼻，且沉于水中；而天然樟腦丸則是光滑的呈無色或白色的晶體，氣味清香，會浮于水中。用于防蟲、防蛀、防霉的天然樟腦丸又被稱為臭珠，原本是從樟樹枝葉中提煉出的有芳香味的有機化合物。也用來制藥、香料等，醫藥上用作強心藥。而含有萘或者對二氯苯的合成樟腦丸則有刺鼻的味道，二氯苯有毒性，它能引起人體中毒癥狀，如倦怠、頭暈、頭痛、腹瀉等。目前市面上出售的樟腦丸80%以上均不同程度地含有萘或者對二氯苯，印有“絕不含萘和對二氯苯，安全、高效、對人體無毒無害”的產品不到1/6。因此選購防蛀劑時一定要注意包裝袋上標注的成分，切莫忽視。

Camphor balls can be divided into natural camphor balls and synthetic camphor balls. It is an organic compound, and camphor balls containing naphthalene are mostly white in color, have a pungent odor, and sink in water; Natural camphor balls, on the other hand, are smooth, colorless or white crystals with a fragrant odor that floats in water. Natural camphor balls, also known as stinky beads, used for insect, moth, and mold prevention, were originally aromatic organic compounds extracted from camphor tree branches and leaves. It is also used in pharmaceuticals, spices, etc., and is used as a cardiac stimulant in medicine. Synthetic camphor balls containing naphthalene or p-dichlorobenzene have a pungent taste, while dichlorobenzene is toxic and can cause symptoms of poisoning in the human body, such as fatigue, dizziness, headache, diarrhea, etc. At present, more than 80% of the camphor balls sold on the market contain varying degrees of naphthalene or p-dichlorobenzene, and less than 1/6 of the products are printed with "no naphthalene or p-dichlorobenzene, safe, efficient, non-toxic, and harmless to the human body". Therefore, when choosing mothproof agents, it is important to pay attention to the ingredients marked on the packaging bag and not ignore them.

樟腦是酮類, 分子式為C10H16O。它是從天然樟木得到的晶體。它特別的香味由晶體升華出來, 能夠用于醫藥及預防昆蟲蛀蝕等方面。正因為它無毒和對人體和衣服沒有任何壞影響, 所以使用樟腦是安全的。

Camphor is a ketone with the molecular formula C10H16O. It is a crystal obtained from natural camphor wood. Its unique fragrance is sublimated from crystals and can be used in medicine and prevention of insect infestation. Because it is non-toxic and has no harmful effects on the human body and clothing, using camphor is safe.

臭丸是由萘制造而成,萘是從原油或煤焦油提取的一種稠環芳烴化合物。它升華出來的“臭”氣有毒性, 尤其傷害肝臟。它也對絲綢和尼龍有化學反應, 所以在這些衣服上會出現一些孔洞。當我們使用臭丸時, 使用1——2個球已足夠, 記緊要用布包著這些臭丸, 以避免臭丸與衣服的直接接觸。

Stinky pills are made from naphthalene, which is a polycyclic aromatic compound extracted from crude oil or coal tar. The "odor" it sublimates is toxic, especially harmful to the liver. It also has a chemical reaction with silk and nylon, so some holes will appear on these clothes. When using stink balls, using 1-2 balls is sufficient. Remember to wrap these stink balls in a cloth to avoid direct contact between them and clothing.
