Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Acima (2000) Determination of Density and Melting Point of Di-n-butyltin-dilaurate Personal Communication from D. Maier to Parametrix, Inc.
Amica (2000) is conducted in line with sound scientific principles and has been allocated a Klimisch score of 2. This has been used as the key study.
Enviro Control Inc. (1980) Hazard information review-dibutylbis-(lauryloxy)stannane. Draft report IR-113 prepared for TSCA Interagency Testing Committee In: Freij L (ed.) KEMI Report No 11/94, Mono- and Di- Substituted Organotins Used as Plastic Additives, Volume 1. Environmental Hazard Assessment (Walterson E et al.). The Swedish National Chemicals Inspectorate.
Result: Melting point was reported as 22-27 ºC at 760 mm Hg
Merck (2008) Safety Data Sheet According to Regulation (EC) No. 1907/2006 (REACH) for dibutyltin dilaurate for synthesis Merck Schuchardt OHG, Hohenbrum, Germany. The Merck Chemical Database Online.
Result: The MSDS for this material reported the melting point to be 25-27 ºC.
Enviro Control (1980) is taken from a government report and Merck (2008) is a Safety Data Sheet and so both have been allocated a Klimisch score of 4.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
28.5 °C

Additional information

Melting point of di-n-butyltin-dilaurate was measured by Buchi melting point apparatus using Pharmacopoea Helvetica method and the result was 28.5 ºC.
