It is one of the chemical constituents that are used in many fragrances such as air fresheners, body sprays, etc. Limonene is not terrible in itself, because it does not cause great harm to human body. In fact, it can be used as seasoning agent for food. However, once it is sprayed into the air, limonene will soon change.
