ENVIRONMENTALTailor-made, wash-active BASFsubstances are all-rounders thatdissolve dirt and protect theenvironment

BASF is one of the largest suppliersof tailor-made wash activesubstances for car washes. Oily andwater-insoluble substances are

dissolved by emulsifiers and finelydispersed in the wash water.Dispersing agents support thedispersion in the wash water andremove solid particles. Surfactantsform a protective foam layer thatreduces the mechanical effects ofcar-wash brushes. Wetting agentsmake the water softer and allow thecar to pearl up residue-free whiledrying. In addition to the cleaningeffect, environment protection is ofprimary importance to BASF.Today’s surfactants arebiodegradable and form foam thateasily disintegrates so that lesswash water is needed.

Textiles: report on implementing codeof good environmental practice [1 table]

A report by the EuropeanCommission, drawn up in the wake ofRecommendation 1998/480/EC,outlines the progress made bymembers of AISE (InternationalAssociation of the Soap andDetergent Industry) on five voluntarytargets set for the end of 2001 undera code of good environmentalpractice for household laundrydetergents. The 15 EU states plusIceland, Norway and Switzerlandhave signed up to the code. TheCommission says that although realprogress has been made, there is stilla long way to go before targets set forend 2001 are met. These are listed.Two of the targets, 10% reduction inper capita consumption of poorlybiodegradable ingredients (PBOs)(kg/per capita); baseline 0.32 kg; andprovision of information toconsumers, were fully met within thefirst years, but the available datasuggests that much remains to bedone in order to reduce consumptionof detergents and packaging. Despitea clear tendency towards lowerconsumption of detergent, the 50%target had still not been met. A tablegives detergent, packaging and PBOconsumption in 1996-1998, 1999-2000 and target for 2001.
