The correct term for the essence obtained from Citrus sinensis, commonly known as sweet orange, is essential oil. Essential oils are concentrated hydrophobic liquids containing volatile aroma compounds from plants. They are typically extracted through methods such as steam distillation or cold pressing, which preserve the beneficial properties and fragrant qualities of the plant material.

In this context, orange essential oil is specifically derived from the rind of the orange fruit, making it a quintessential example of an essential oil. This categorization is significant as essential oils are often used in aromatherapy, perfumery, and various therapeutic applications due to their aromatic and medicinal properties.

While the other terms—absolute, infusion, and extract—are related to botanical extractions, they pertain to different processes or uses. An absolute is a more concentrated extraction often used in the perfume industry, an infusion involves soaking plant material in oil or water to extract flavors or properties without necessarily isolating the volatile components, and an extract typically refers to a broader category that can include various extraction methods yielding concentrated plant substances. Hence, referring to the orange essence as an essential oil is both accurate and appropriate for its extraction method and application.
