Description

Caprylic Acid, also known as Octanoic Acid, is a naturally occurring medium-chain fatty acid with a distinctive fatty, waxy and slightly pungent odor profile. At appropriate dilution, it can contribute creamy, dairy-like, cheesy and slightly coconut-like nuances to fragrance compositions.

In perfumery, Caprylic Acid is primarily used as a specialty modifier rather than a dominant fragrance ingredient. It can help create realistic dairy, fatty, creamy, coconut and natural animalic effects and is particularly useful in complex gourmand and natural-style compositions.

Because of its strong character, careful dilution and dosage are important. When used appropriately, it can add realism and depth to accords that would otherwise feel overly clean or synthetic.

Perfumers' Tip

Caprylic Acid is a powerful specialty material, so it should generally be evaluated in a highly diluted solution. Tiny amounts can add realistic fatty and dairy nuances, while excessive use can quickly become harsh or rancid. Pair it with lactones for a creamy coconut or dairy effect, or use it with fruity materials to create more realistic tropical and gourmand accords.
