Description of key information

No hydrolysis of Flux1 is expected as chemical structures of each constituents are without any group that can be hydrolysed.

Flux1 is a reaction mass of carbon tetrachloride (CAS n° 56-23-5), 1,2-Dichloroethane (CAS n°107 -06 -2) and chloroform (CAS n° 67-66 -3).

A weight of evidence approach has been developped as hydrolysis studies are available on carbon tetrachloride and chloroform (2 constituents of Flux1): hydrolysis is not expected for both constituents.

In the review of Mabey & Mill (1978), it is states that a half life of 7000 years for a concentration of 1 ppm and 7 years for a high concentration of 1000 ppm was calculated at standard temperature (298K) for carbon tetrachloride. Therefore, hydrolysis is not a degradation relevant process for carbon tetrachloride under environmental conditions.

Jeffers et al. (1982) showed that the hydrolysis rate of chloroform was 7.13 e-10, and the estimated half-life was 1850 years. No hydrolysis is expected for chloroform.

Based on a weight of evidence approach on data available on both constituents, no hydrolysis of Flux1 is expected.
