Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Based on availability of acute aquatic toxicity data from three trophic levels the PNEC Aqua freshwater is derived. Based thereupon by using default calculations as described in ECHA guidance PNEC aqua marine water, PNEC aqua intermittent release are derived. The PNEC sediment (freshwater and marine water and PNEC soil are derived using the equilibrium partitioning method.

The PNEC for sewage treatment plant is based on the acute bacterial toxicity result from a sludge respiration inhibition test.

The PNEC oral predators is based on the NOAEL derived from the 90d feeding study with rats considering the applicable default correction factors.

Conclusion on classification

Based on the data of L-Menthol:

- The substance is ready biodegradable

- Log Kow = 3.15

- BCF = 0.5 - 15 l/kg

- Fish : LC50 at 96h = 15.6 mg/L

- Daphnia : EC50 at 48h = 26.6 mg/L

- Algae (Desmodesmus subspicatus) : EC 50 at 72h = 21.4 mg/L with a NOEC at 9.65 mg/L

- Inhibition of activated sludge respiration was determined : EC50 = 237 mg/L

 

The substance does not meet the classification criteria for acute aquatic toxicity according to Regulation (EC) No. 1272/2008 as the most sensitive EC50 is >1 mg/L.

The substance also does not require classification for chronic aquatic toxicity according to the criteria as laid down in Regulation (EC) No. 1272/2008 as L-Menthol is readily biodegradable and has a BCF of 15 and thus less than 500. The same applies when comparing to classification criteria according to Directive 67/548/EEC (Dangerous Substance Directive - DSD) as L-menthol is readily biodegradable neither long term nor short term classification is required.
