Surfactants and builders ale the two most important ingredients in laundry,household and personal-care cleaning products.They play a key role in washing processes.The development of various suffactants(e.g.,anionic,nonionic,cationic,zwitterionic,and silicone surfactants)and builders(inorganic,organic and polymeric builders)used in the detergent compositions ale reviewed and their detergency pe~ormance and blOdegradablllty ale discussed.In the future.the development of the surfactants and builders used in detergent compositions should be based on economic and environmental considerations.The use of the eco-friendly surfactants and builders derived from inexpensive renewable resources(e.g.,alkyl polyglucosides and bio-based polyesters)in detergent compositions is the developing trends in detergent industry.
