Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Stability:
The results of the hydrolysis study show that abiotic hydrolysis of menthyl lactate does not contribute to the degradation of the substance in the environment.
Biodegradation:
A guideline-conform ready biodegradability study was conducted. The substance was readily biodegradable in the study fulfilling the 10-day window. Menthyl lactate therefore is considered to rapidly degrade in the environment. In consequence the substance can be considered as fulfilling the "not (v)P" criterion for vPvB and PBT assessment.
Bioaccumulation:
The BCF of the substance was calculated with the program BCFBAF using a fragment-based approach (Meylan et al. 1999) and with a QSAR built on the relationship between log Kow and BCF (Veith et al. 1979). The predicted values were 130 L/kg and 284 L/kg, respectively. The B criterion is not fulfilled for the substance menthyl lactate and the substance is considered as not bioaccumulative.
Transport and distribution:
The log Koc value was predicted with the program KOCWIN and with three QSPR methods. The geometric mean of three QSPR results of log Koc = 3.05 indicates that the substance has low mobility in soil and sediment according to the classification scheme of McCall et al. (1981). The Henry's Law constant that can be calculated with the EUSES modelling tool (version 2.1.2) from the available information on vapour pressure and water solubility shows that the substance is non-volatile under environmental conditions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
