D-Limonene

Also known as r-limonene, orange peel oil, citrene, or simply just limonene, d-limonene (the more common isomer to l-limonene) conveys an aroma that is “like lemon, making it widely used as a flavor and fragrance additive in common foods, such as fruit juices, candies, chewing gums, soft drinks, and ice creams.”

A recent study noted that d-limonene is one of the most common fragrances used in the formulation of cosmetics and can be found in many types of beauty products.
