Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The absence of specific toxicokinetic data from animal testing means that it is not possible to make firm conclusions concerning the absorption, distribution, metabolism or excretion.
Key value for chemical safety assessment
Additional information
Toxicokinetic assessment
The data provided suggested no significant clinical signs. No useful evidence relating to toxicity was obtained from the data provided for the acids.
Absorption
There was no evidence of systemic effects reported in the data provided on the acute oral or dermal toxicity studies, but blood parameter changes observed in the repeat dose oral toxicity study would suggest that absorption does take place orally.
Distribution
System effects were observed in the subacute oral toxicity study with changes in blood chemistry and minor findings in the liver and kidneys. It is therefore possible to conclude that the substance, or the metabolites, are transported.
Metabolism
The triethanolamine will readily metabolise, with the nitrogen and carbon being utilised. There is no evidence of metabolic activity in animals, but work on phenylsulphonamides suggests metabolic pathways will exist in cells.
Excretion
There is no evidence from testing performed that there is subsequent excretion of the absorbed substance or any metabolites formed.
Conclusion
The absence of specific toxicokinetic data from animal testing means that it is not possible to make firm conclusions concerning the absorption, distribution, metabolism or excretion. It is not considered appropriate to perform further animal studies on this substance.
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).
