Description of key information
Phototransformation in air
The available 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 water molecule of hydroxide ion substitutes for another atom of 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.
Phototransformation in water
The available 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 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.
Biodegradation in water: screening tests
There is data available for this substance and based on this data, this substance is considered readily biodegradable.
Biodegradation in water and sediment: simulation tests
This substance is considered to be readily biodegradable. Therefore, in accordance with REACH Annex IX column 2 exemption, the simulation testing in water and sediment does not need to be conducted.
Biodegradation in soil
This substance is considered to be readily biodegradable. Therefore, in accordance with REACH Annex IX column 2 exemption,simulation testing on ultimate degradation in soil does not need to be conducted.
Bioaccumulation: aquatic/sediment
Standard Bioaccumulation studies for this endpoint are intended for monoconstituent substances and are not appropriate for petroleum UVCB substances. In accordance with Annex XI Section 1.3 the endpoint has been fulfilled using QSAR calculations for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see the representative structures from the PETRORISK Product Library in the spreadsheet attached in IUCLID section 13.2). As such, testing is not scientifically necessary.
Adsorption / desorption
Standard adsorption studies for this endpoint are intended for monoconstituent substances and are not appropriate for petroleum UVCB substances. In accordance with Annex XI Section 1.3 the endpoint has been fulfilled using QSAR calculations for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see the representative structures from the PETRORISK Product Library in the spreadsheet attached in IUCLID section 13.2). As such, testing is not scientifically necessary.
Henry's Law Constant
Standard Henry's Law Constant studies for this endpoint are intended for monoconstituent substances and are not appropriate for petroleum UVCB substances. In accordance with Annex XI Section 1.3 the endpoint has been fulfilled using QSAR calculations for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see the representative structures from the PETRORISK Product Library in the spreadsheet attached in IUCLID section 13.2). As such, testing is not scientifically necessary.
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
