Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No toxicokinetic (absorption, metabolism, distribution, elimination) data is available for MEA-Polyborate. Available data is primarily physico-chemical properties that influence the absorption and distribution of the substance in the body. Both 1:1 and 1:3 mole ratios of MEA to boric acid are infinitely soluble in water with log Pow of -0.9 for the polyborate moiety by ICP-MS and log Pow of -2.5 for the organic moiety by LC-MS. The log P values indicate that both ratios of MEA-Polyborate will likely be 100% absorbed in the gastrointestinal track, primarily found in the blood serum and excreted primarily via the kidneys in the urine. The log P values also indicate that both ratios of MEA-Polyborate is poorly absorbed through the skin with dermal absorption rates similar to monoethanolamine. No data is available on the metabolism of MEA-Polyborate.
