Description of key information

1,2-Dihydro-2,2,4-trimethylquinoline, oligomers as a mixture of oligomer derivatives TMQ is insoluble in water (<1 mg/L). Therefore a study on hydrolysis is considered unnecessary in accordance with column 2 of REACH Annex VIII and scientifically unjustified according to Section 1 of REACH Annex XI. Results from controls of photolysis study (dark control), a half-life of ca. 16 hours of 1,2-Dihydro-2,2,4-trimethylquinoline, oligomers was reported. However, as only a small portion of the substance is water soluble, this result is not used for further evaluation.
