Conclusion on classification

Environmental fate and pathways

Water solubility: 0.027 mg/L at 20 °C, pH 7 Degradation

Biodegradation: not readily biodegradable (0% after 28 d)

Bioaccumulation: Low potential for bioaccumulation (BCF: 271 L/kg)

Acute aquatic toxicity

No observed toxicological effects up to the limit of water solubility

Fish: Oryzias latipes LC50 (96 h): > 5 mg/L (range finding study, OECD 305)

Aquatic invertebrates: Daphnia magna EL50 (48 h): > 10 mg/L (OECD 202)

Algae: Desmodesmus subspicatus EL50 (72 h): > 10 mg/L (OECD 201)

Chronic aquatic toxicity

No observed toxicological effects up to the limit of water solubility

Fish: No data available

Aquatic invertebrates: No data available

Algae: Pseudokirchneriella subcapitata NOEL (72 h): > 10 mg/L (OECD 201)

 

CLP: 

2,5-bis(1,1,3,3-tetramethylbutyl)benzene-1,4-diol is not readily biodegradable and is considered to be not toxic to fish, aquatic invertebrates or algae. All available acute and chronic effect concentrations are > 1 mg/L. based on the absence adverse effects within the limits of water solubility. The substance has a low potential for bioaccumulation (BCF < 500). Therefore, the substance is not classified and labelled for environmental hazards according to the consolidated version of Regulation (EC) No 1272/2008 and further amendments (ATPs).
