Laundry Detergent Testig Guidelines - Minimum requirements for comparative detergent testing

Laundry detergents are sometimes compared on performance, e.g. by consumer organisations. But to be useful for consumers, it is important that these tests are of high quality and offer a realistic and reliable comparison of product characteristics.

A.I.S.E. developed its first detergent testing guidelines in 2009 and has since been updating it on a regular base, making it available to manufacturers and other interested parties such as consumer organisations and testing institutes. 
The protocol provides a minimum requirement methodology for assessing the performance of laundry detergents (heavy duty and light duty) and laundry additives across Europe. The Guidelines have been developed based on experts' knowledge from major companies manufacturing such products, after a thorough review of existing test protocols used in Europe and of existing internal company data.


The protocol comprises (as minimum requirements - bearing in mind that organisations may feel free to exceed them):

A.I.S.E. reviews this protocol regularly and is open to any feedback, reaction or suggestion.

Status of the review of the protocol – February 2017

Stain Set - the A.I.S.E. Working Group has concluded the project which aimed at developing a body soil stain in December 2015. 
Due to several limitations, no single model stain could be identified allowing for an A.I.S.E. recommendation for a representative body/collar soil - please find more information in this document and power point presentation. 

Dye Transfer Inhibition Protocol - the group has started in late 2013 to work on the addition of two new dies. Validation is ongoing.

Whiteness Maintenance Protocol - the group has started in 2015 a programme to further develop the whiteness test method in a more consumer relevant way. The screening tests with test institutes are expected to start still this year and the whiteness tests are to be prolonged until end of 2016.
