Description

Diphenyl Oxide (DPO), also known as Diphenyl Ether, is a distinctive aroma chemical with a warm, sweet and floral character. Its odor profile features geranium-like and rose-like nuances accompanied by soft, powdery and slightly woody facets. It has a substantive character that allows it to contribute depth and persistence to fragrance compositions.

In perfumery, Diphenyl Oxide is used as a supporting ingredient in floral, woody and powdery compositions. It can add warmth and body to the fragrance while helping create a smooth transition from the floral heart toward the base. Its characteristic floral profile can be useful in geranium and rose-style accords, while its persistent nature makes it valuable when a fragrance needs greater staying power. It is generally better suited to experienced formulation work because of its distinctive and relatively strong character.
