General description

Dulcin (p-ethoxyphenylurea) is an early synthetic sweetener that is not approved for food use in most jurisdictions due to safety concerns. Testing is important to detect illicit adulteration of foods, beverages, and supplements with non‑approved sweeteners. Sensitive analytical methods such as LC–MS/MS or HPLC can quantify dulcin at low levels in complex matrices. Routine screening helps protect consumers, monitor supply chains, and flag suspicious products where unexpected sweetness or inconsistent declarations are observed.
