Diphenyl ether

Diphenyl ether (CAS 101-84-8), also known as phenyl oxide and DPE, is an aromatic compound used as a fragrance ingredient and flavoring agent across personal care and food-adjacent applications. With FEMA 3667 designation, it is recognized as a flavor material delivering a distinctive geranium-like, rose-nuanced character. In fragrance formulation, DPE contributes a floral note to fine fragrances.

It is frequently utilized in soaps and cosmetic products where lasting aromatic character is required. As a FEMA-designated flavoring agent, it is used at controlled trace levels in food and beverage applications. The compound imparts subtle floral nuances to various consumer goods. In personal care manufacturing, it functions as a scenting component in lotions, creams, and rinse-off products for daily use.

Pharmaceutical and healthcare product formulators also incorporate it where both fragrance masking and mild preservative-adjacent properties are relevant to the finished formulation and stability. Diphenyl ether is supplied as a colorless to pale liquid in standard packaging suited for fragrance and flavor industry handling. It is available in flavor and fragrance grade for industrial use.

The supply conforms to FEMA 3667 specifications as the primary quality benchmark for buyers in these sectors. Drum and smaller lot quantities are typical for specialty fragrance and flavor procurement channels.
