Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Phototransformation in air

The available weight of evidence demonstrates that this substance does not absorb light within a range of 290 to 750 nm, the range in which photolysis occurs. Therefore, direct photolysis will not contribute to the degradation of this substance in the air. Further testing is not required under Annex XI, section 1.2.

 

Hydrolysis

 

Hydrolysis is a reaction in which a hydroxide ion of a water molecule substitutes for another atom or group of atoms present in a chemical resulting in a structural change of that chemical. Potentially hydrolysable groups include alkyl halides, amides, carbamates, carboxylic acid esters and lactone epoxides, phosphate esters, and sulfonic acid esters. The lack of a suitable leaving group renders compounds resistant to hydrolysis.

 

The chemical constituents that comprise the substance consist entirely of carbon and hydrogen and do not contain hydrolysable groups. As such, they have a very low potential to hydrolyze. Therefore, this degradative process will not contribute to their removal from the environment.

In accordance with section 1 of REACH Annex XI, the hydrolysis study does not need to be conducted as this substance is not expected to undergo hydrolysis in the environment due to a lack of hydrolyzable functional groups and therefore not conducting the test is scientifically justifiable.

 

Phototransformation in water

 

The available weight of evidence demonstrates that this substance does not absorb light within a range of 290 to 750 nm, the range in which photolysis occurs. Therefore, direct photolysis will not contribute to the degradation of this substance in the aquatic environment. Further testing is not required under Annex XI, section 1.2.

 

Phototransformation in soil

 

The available weight of evidence demonstrates that this substance does not absorb light within a range of 290 to 750 nm, the range in which photolysis occurs. Therefore, direct photolysis will not contribute to the degradation of this substance in the terrestrial environment. Further testing is not required under Annex XI, section 1.2.
