Methyl aminolevulinate
Summary
Persistence. The potential for persistence of methyl aminolevulinate cannot be excluded, due to lack of data.
Bioaccumulation. Methyl aminolevulinate has low potential for bioaccumulation.
Toxicity. It cannot be excluded that methyl aminolevulinate is toxic, due to lack of data.
Risk. Risk of environmental impact of methyl aminolevulinate cannot be excluded, since there is not sufficient ecotoxicity data available.

Detailed information
Fass environmental information
Fass environmental information for Metvix (methyl aminolevulinate) from Galderma Nordic AB (retrieved on 2025-11-11).
Hazard
Persistence: Methyl aminolevulinate should be regarded as potentially persistent due to lack of degradation data. No systemic studies according to OECD 301, 302 or 308 have been conducted, and no abiotic data are available. Methyl aminolevulinate is a methyl ester of 5-aminolevulinic acid (ALA), an endogenous compound naturally present in all living cells.
Bioaccumulation: Log Dow = -1.93 at pH 7.4 (OECD 107).
Toxicity: No data.
Risk
PEC/PNEC is based on sales data in Sweden in year 2022.
PEC = 4.28 10-4 microg/L.
Risk of environmental impact of methyl aminolevulinate cannot be excluded, since there is not sufficient ecotoxicity data available.
