Octanal is an organic compound, typically appearing as a pale yellow liquid with a waxy-orange aroma. This ingredient appears as a component of some of the essential oil fragrances we use in our products.

Octanal is in a class of chemicals known as aldehydes, which can be found in trace amounts in many plants and their essential oils. Octanal is naturally present in citrus fruits such as Sweet Oranges (Citrus sinensis), Lemons (Citrus limon) and Yuzu (Citrus junos). It can be used to add intense citrus notes to fragrances.
