Reaction Products of (Z)-octadec-9-enol and lactic acid
Clear yellow liquid
Sponsor lot number: P7610
Purity: 100%
Molecular weight: 340.5405 g/mol
Arrival date: 7 February 2018
Re-test date: 31 January 2020
Storage conditions: Room temperature (15 to 30°C) - Boiling pt.:
- 225 °C
- Atm. press.:
- 1 013 hPa
- Conclusions:
- A small exotherm from -50 to -35°C was observed, which would suggest solidification of a mixture (when a liquid is super cooled it may solidify when the temperature is increased). This was followed and endotherm from -33 to -2°C, which would suggest a mixture melting; this was confirmed by the freezing temperature test in this report, which was within this range
An exothermic artefact was recorded starting at 127°C, peaking at 225°C. A large exothermic reaction was observed to start at 333°C, which would be associated with decomposition. This was confirmed by a straw coloured liquid remaining in the crucible and a red stain on the outside of the lid. - Executive summary:
In this guideline (OECD 103) study, [conducted with GLP certification], A small exotherm from -50 to -35°C was observed, which would suggest solidification of a mixture (when a liquid is super cooled it may solidify when the temperature is increased). This was followed and endotherm from -33 to -2°C, which would suggest a mixture melting; this was confirmed by the freezing temperature test in this report, which was within this range
An exothermic artefact was recorded starting at 127°C, peaking at 225°C. A large exothermic reaction was observed to start at 333°C, which would be associated with decomposition. This was confirmed by a straw coloured liquid remaining in the crucible and a red stain on the outside of the lid.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
