Limonene itself is not considered carcinogenic. In fact, it is commonly found in many citrus essential oils and is generally recognized as safe for use in food and cosmetics. However, limonene can react with ozone in the air to form formaldehyde, which is a known carcinogen. Therefore, it is important to use essential oils containing limonene in well-ventilated areas to minimize the risk of formaldehyde formation. **

Limonene itself is not considered carcinogenic. In fact, it is commonly found in many fruits and plants and is generally recognized as safe for use in food and cosmetics. However, when limonene is oxidized, it can form compounds that have been shown to be carcinogenic in animal studies. Therefore, it is important to use limonene-containing essential oils from reputable sources and store them properly to minimize oxidation. **

The functional group of limonene is a cyclic alkene, specifically a monocyclic terpene. It contains a double bond within its carbon ring structure, which gives it its characteristic chemical properties and reactivity. This functional group is responsible for many of the biological and industrial properties of limonene, including its use as a solvent, fragrance, and flavoring agent. **
