Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The PNEC values were determined for the substance itself by application of methods provided in ECHA Guidance Chapter R.10 (May 2008).

Conclusion on classification

The short-term toxicity of the substance to aquatic organisms was investigated according to valid HA-QSARs. The following toxicity values are available for the substance:

Fish Acute: 96h-LC50 = 25.0 mg/L

Aquatic invertebrates: 48h-EC50 = 24.0 mg/L

Algae: 72h-EC50 = 24.0 mg/L

The lowest acute aquatic toxicity values based on available data ranges between 10 and 100 mg/L. Long-term toxicities to aquatic organisms were not investigated. Thus, there are no adequate chronic toxicity data available.

The degradation of the substance was investigated according to OECD Guidelines:

In a ready biodegradation study performed according to OECD Guideline 301 C, camphor was tested at concentrations of 100 mg/L and the inoculum was activated sludge (30 mg/L). The degradation of the test material was assessed by the determination of the oxygen consumption.

At 100 mg/L test concentration, 94% degradation (biochemical oxygen demand) was reached in 28 days. Under the test conditions, the substance was determined to be ready biodegradable. Therefore, the substance is considered as rapidly degradable in aquatic system.

No fish BCF is available. Log Kow is 2.38.

CLP Classification proposal

It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation (including 2nd Adaptation to Technical Progress, Com Reg No 286/2011).

Acute aquatic hazard: not classified. Reasoning: lowest E(L)C50 higher than 1 mg/L.

Chronic aquatic hazard: not classified. Reasoning: adequate chronic toxicity data are not available, lowest acute E(L)C50 value range between 10 and 100 mg/L, rapidly degradable substance with Log Kow < 4.
