Batches of LAS vs. detergent batches

Print this page

The Rinsing Protocol of standard AHAM HLW-1 uses the LAS (anionic surfactant) of the test detergent as a marker for assessing rinsing efficiency of a wash process. The analytical method (UV spectrophotometry) is calibrated with the LAS component itself, samples of the actual batches of LAS mixed into the detergent batches can be made available on request. Here is a list of detergent batches produced since 2012 and the respective LAS batches (if available):
