EU labeling rules require emulsifiers to be declared on product labels, either by name or by their E-number. EFSA safety evaluations underpin E-numbers, after which the European Commission authorises their use. The document lists several emulsifiers and their permitted applications in foods within the EU, including polyoxyethylene (40) stearate (E 432) in wine under Regulation (EEC) No 1873/84; ammonium phosphatides for cocoa and chocolate; acetic acid esters (E472b, E472c); lactic and citric acid esters of mono- and diglycerides; mixed esters and polysorbate 20. These entries describe typical applications, texture and stability roles, and the regulatory context for declaring additives on product labels.
