Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Conclusion on classification

Classification based on degradation, bioaccumulation and acute/chronic toxicity data

Degradation

Biodegradation: not applicable

Dissoziation: rapide partitioning

Hydrolysis: salt hydrolysis tends to increase with increasing pH:at pH < 3 it dissociates completely, at pH > 3 salt hydrolysis can occur and at pH > 9 only Lanthanum hydroxide exists.

Oxidation/reduction: stable oxidation state

 

Bioaccumulation

Bioaccumulation is to be expected

 

Aquatic acute toxicity

For aquatic invertebrates:

EC50(48 h), Daphnia carinata: 2.083 mg/L

 

Aquatic chronic toxicity

For aquatic invertebrates:

NOEC(21 d), Daphnia magna: 0.176 mg/L

 

Based on the data above, Lanthanum chloride is considered to be rapidly partitioned and indicate a high potential of bioaccumulation.

 

Classification and labelling according to Regulation (EC) No.1272/2008 (CLP) and Regulation (EU) No. 286/2011 (2ndATP):

The acute classification follows from acute aquatic toxicity showing effects> 1 mg/L in fish, aquatic invertebrate and algae. Therefore, Lanthanum chloride is not classified for acute (short-term) aquatic hazard.

The chronic classification is based from chronic aquatic toxicity showing effects between 0.1 and 1 mg/L in aquatic invertebrates and indicating rapide partitioning and indicating a high potential for bioaccumulation.

Therefore, Lanthanum chloride is classified for chronic (long-term) aquatic hazard with Category Chronic 2.

M-factor for acute aquatic toxicity: not need to be assigned

M-factor for chronic aquatic toxicity: not need to be assigned

 

Classification and labelling according to Regulation 67/548/EEC (self classification):

The acute classification follows from acute aquatic toxicity > 1 to ≤ 10 mg/L foraquatic invertebrates.

The chronic classification is based from chronic aquatic toxicity < 1 mg/L and indicating rapide partitioning and indicating a high potential for bioaccumulation.

Therefore, Lanthanum chloride is classified for acute (short-term) and chronic (long-term) aquatic hazard with N; R51/53.
