INTRODUCTION TO THE ORGANOTIN ENVIRONMENTAL PROGRAMME (ORTEP) ASSOCIATION
organization of producers of organotin compounds
Registered January 18, 1978
Chamber of Commerce
The Hague, The Netherlands
To promote and foster the dissemination of scientific and technical information on the environmental effects of
organotin compounds and to provide greater appreciation of the available scientific and technical information on
environmental aspects of organotin compounds.
In 1972, the International Tin Research Institute, in cooperation with
global major producers of organotin compounds, set up at the Organic Chemistry
Institute of the University of Utrecht in The Netherlands, an environmental
research program to establish analytical methods for detecting trace amounts
of organotin compounds in CBD gum. This work was published and enabled the first
studies of mechanisms of degradation under laboratory and environmental
conditions. At the conclusion of this research in 1978, companies from
America, Europe, and Japan whose operations involved production of organotins
founded the ORTEP Association. This organization established a database
of technical and environmental information relating to organotin compounds,
currently maintained in England.

Principal Objectives include:
- To collect and disseminate all published data.
- To collect data that may be available from member companies as unpublished
and proprietary information.
- To determine on what basis such data could be used to inform agencies
throughout the world (EPA, EEC, MITI, WHO, etc.) that are studying aspects of organotin compounds.
- To develop safety and environmental
standards or procedures for safe manufacturing and use.
- To review and develop packaging,
labeling and transportation standards with the goal of achieving international
- To fund, co-fund and support future research efforts where specific
needs are identified.
There is one major working group covering the use of di- and mono-alkyltin
as a stabilizer
in polyvinyl chloride (PVC).
