Beschreibung
Zusammenfassung:	The present invention provides a polyethylene glycol (PEG) ester surfactant comprising at least one polyethylene glycol moiety and at least one fatty acyl moiety characterised in that said moieties are linked by a linkage incorporating a biodegradable methylene diester unit of formula (I) -CO.O.C(R )(R ).O.CO- where R and R may, for example, each be a hydrogen atom or a monovalent organic group attached through a carbon atom or R and R together may, for example, form a divalent organic group attached through carbon atoms.
