History

  • 1988

  • 1988/1989

    Studies presented at symposium in Aachen Germany affirm use of LAS; two studies presented by CLER/ECOSOL scientists; studies subsequently published in Tenside Surf. Det. (vol. 32, issue 2, 1989).

  • 1990

    CLER/ECOSOL scientists publish two studies on LAS environmental safety.

  • 1991

    Published study shows LAB safe for the environment; CLER scientists conducted study.

  • 1992

    CLER/ECOSOL research (four studies) presented at major surfactants congress (CESIO).

  • 1993/1994

    CLER scientists present study on LAS safety in anaerobic sediments at World Detergents Conference (Montreux).

    ECOSOL scientists publish paper on LAS removal in sewage treatment in Italy.

  • 1995

    Life Cycle study published comparing all surfactants used in cleaning products in Europe; no surfactant found superior to LAS: ECOSOL members contribute data on LAB and LAS.

    Dutch government says low environmental risk of LAS and other laundry components; ECOSOL sponsors data compilation on LAS; study published in 1999.

    CLER publishes first issue of technical journal, The CLER Review.

  • 1996

    OECD (Organization for Economic Cooperation and Development), EPA complete health and environmental assessment of LAB, concluding “no need for further work” (low concern); CLER member company prepared data dossier and assessment; assessment available on UN International Program on Chemical Safety (ICPS) website (www.inchem.org).

    Published study confirms environmental safety of LAS co-product (DATS, di-alkyl tetraline sulfonate); CLER scientists conducted study.

    Volume 2 of the CLER Review published; includes four papers by CLER/ECOSOL scientists.

  • 1997

    CLER publishes Vol. 3 of the CLER Review; five studies find LAS poses little or no threat to the aquatic environment.

    CLER introduces comprehensive website, www.cler.com.

  • 1998

    CLER expands membership; represents North and South American LAB producers.

    CLER and ECOSOL unite at World Detergents Conference (Montreux) with first joint exhibition booth.

    CLER publishes Vol. 4 of the CLER Review; includes two papers by CLER scientists.

  • 1999

    CLER Publishes Vol. 5 of the CLER Review; six studies (one by ECOSOL member) demonstrate safety of LAS for terrestrial environment.

  • 2000

    First studies demonstrating LAS anaerobic biodegradation reported at CESIO Congress, published in Vol. 6 of CLER Review; includes four studies by ECOSOL scientists.

  • 2002

    Vol. 7 of the CLER Review is published; five studies re-affirm the safety of LAS in sewage bio-solids (sludge) used as fertilizer/soil conditioner in agriculture.

  • 2003

    Vol 8 of CLER Review published; study by American Cleaning Institute demonstrates LAS in cleaning products safe for disposal to household septic systems; CLER scientists participate in study.

    Published study confirms LAS anaerobic biodegradation; ECOSOL scientists are co-authors.

  • 2004

    HERA Project conducts comprehensive health and environmental assessment of LAS usage in household products in Europe; concludes LAS “safe for man and the environment”; assessment published on project website (www.heraproject.com/) and published in Vol. 9 of The CLER Review; ECOSOL scientists assist with assessment.

  • 2005

    OECD/EPA complete health and environmental assessment of LAS, concluding “low priority for further work” (low concern); CLER-led consortium prepared data dossier and assessment; assessment available on UN ICPS website (www.inchem.org) and published in Vol. 10 of CLER Review.

  • 2007

    Vol. 11 of the CLER Review is published, featuring a new study (Cadiz Univ., Spain) demonstrating anaerobic biodegradation of LAS in marine sediments. CLER and ECOSOL scientists contributed two studies, one an updated safety assessment of LAS in agricultural soil and the other a review of the 2007 updated HERA Project report on LAS.

  • 2008

    OECD/EPA complete health and environmental assessment of HAB (heavy alkylate bottoms, LAB co-product); assessment concludes adequate data available and low hazard potential (low concern); assessment published on UN ICPS website (www.inchem.org); CLER/ECOSOL prepared data dossier and assessment.

  • 2010

    The LAB and Derivatives REACH Consortium, led by ECOSOL members, successfully registers all the members of the LAS value chain (LAB, HAB, LAB Sulfonic Acids and LAS) in the REACH chemicals registration program in Europe:

    Data on LAB may be found at https://echa.europa.eu/registration-dossier/-/registered-dossier/15763

    Data on HAB at: https://echa.europa.eu/registration-dossier/-/registered-dossier/15959

    Data on LAS at: https://echa.europa.eu/registration-dossier/-/registered-dossier/15879

    Data on LAB Sulfonic Acids (LAS Acid) at: https://echa.europa.eu/registration-dossier/-/registered-dossier/15438.
