Description of key information
A hydrolysis study has been conducted on triisodecyl phosphite (TDP), a constituent and related substances. Based on the results, this substance is anticipated to rapidly hydrolyze in water.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 17 h
- at the temperature of:
- 23 °C
Additional information
It was also observed that TDP hydrolyzed fairly rapidly at 23 C in aqueous/acetonitrile (1/1) solutions, with half-lives ranging from 4 to 20 hours over a pH range of 5 to 9 respectively. As such it is anticipated that the component chemicals of this substance will hydrolyze rapidly with half-lives ranging from about 4 to 20 hours (at higher pH).
At normal pH (7) this class of phosphites in general had halves in the range of 0.5 - 20 hrs.Al-Lohedan et al., (1991) reported a TPPi hydrolysis half-life of 1.1 h in water at pH 1.3 and 25 °C by extrapolation of results on TPPi solutions in ethanol/water. The results of BCRI experiments on aqueous/cosolvent TPPi solutions indicated that the half-lives of TPPi in deionized water (initially at pH 6 - 7) and pH 9 buffer were approximately 0.5 h and less than 14 h respectively, at 22 °C.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
