Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE”, a simulation testing on ultimate degradation in surface water, the study does not need to be performed if the substance is ready biodegradable. Pentan-1-ol/Amyl alcohol, Carbon disulphide and Allyl Chloride are both reagents used in the manufacture of S-allyl O-pentyl dithiocarbonate.Therefore, the Biodegradation in water of Pentan-1-ol/Amyl alcohol, Carbon disulphide and Allyl Chloride need to be considered in the assessment of S-allyl O-pentyl dithiocarbonate. The results suggest that Pentan-1-ol/Amyl alcohol, Carbon disulphide and Allyl Chloride are readily biodegradable and S-allyl O-pentyl dithiocarbonate will be readily biodegradable and it is not expected to persist in the environment. As S-allyl O-pentyl dithiocarbonate is ready biodegradable a ready biodegradability study does not need to be conducted. Therefore testing for Biodegradation in water does not need to be performed.

Key value for chemical safety assessment
