Conclusion on classification

Classification related key information

 

Biodegradation:

·        Biodegradation in water: 0% (based on O2 consumption) in 28 d (OECD 301 F, 302 C)

 

Bioaccumulation:

·        log Kow: 10.1 (OECD 117)

·        BCF (0.01 mg/L) : <9 to 45, BCF (0.001 mg/L): <76 to 94 (OECD 305)

·        BCF = 60.74 L/kg (BCFBAF v3.01, EPISUITE v 4.11)

 

Water solubility:

·        Water solubility < 0.00042 mg/L

 

Acute toxicity:

·        to fish: LC50 (96 h, Gobiocypris rarus) > 100 mg/L (nominal, OECD 203)

·        to aquatic invertebrates: EC50 (48 h, Daphnia magna) > 100 mg/L (nominal, OECD 202)

·        to algae: EC50 (72 h, Pseudokirchneriella subcapitata) > 100 mg/L (nominal, OECD 201)

 

Chronic toxicity:

·        to fish: NOEC (28 d, Gobiocypris rarus) ≥ 100 mg/L (nominal,OECD 204)

·        to aquatic invertebrates: NOEC (21 d, Daphnia magna) ≥ 10 mg/L (nominal, OECD 211) based on reproduction

·        to algae: LOEC (72 h, Pseudokirchneriella subcapitata) > 100 mg/L (nominal, OECD 201)

 

Classification justification according to CLP

 

Reaction mass of 1,1'-(isopropylidene)bis[3,5-dibromo-4-(2,3-dibromo-2-methylpropoxy)benzene] and 1,3-dibromo-2-(2,3-dibromo-2-methylpropoxy)-5-{2-[3,5-dibromo-4-(2,3,3-tribromo-2-methylpropoxy)phenyl]propan-2-yl}benzene is not readily biodegradable but showed no acute or long term aquatic toxicity effects up to the limit of water solubility and reveals a BCF of < 500. Therefore, the substance does not need to be classified and labelled as hazardous to the environment according to the consolidated version of Regulation (EC) No.1272/2008 (CLP) and all further amendments (ATPs).
