Annex 2 – Commercial LAS (C11.6 – C11.8) Acute Toxicity Data
This Annex provides the results of an extensive review of the data previously compiled by BKH
(1993) and of the published and unpublished literature since this data compilation (HERA 2004).
The purpose of this review is to identify the lowest valid acute toxicity values on commercially
representative LAS, having average alkyl chain lengths of C11.6 to 11.8 (Table, SIAR Section 1.1).
Valid studies on commercial LAS on test species for which there are OECD acute toxicity
guidelines are listed in the tables below. References to the published studies follow the tables.
Studies that were not valid, or were not conducted on commercial LAS, are listed in the table of
rejected studies along with the reasons for rejection.
Lowest valid values for each taxon are identified in the table. Robust summaries of these studies
are included in the dossier. The location of other studies provided in the dossier are noted under
Remarks.
Note that all non GLP studies date before the implementation of OECD GLP guidelines. Studies
noted as QA are those whose report mentioned a specific Quality Assurance program.
