Additional information

Tridecylamine, branched and linear (CAS 86089-17-0) is a mixture composed of (predominantly) groups of isomers with chain lengths ranging from C11 to C14 and, to a minor content, of C10 alkylamines. The main fraction are C13 -amines, followed by the C12 - , C11 - and C14 -amines.

GC/MS analysis confirmed the following relative distribution of the detected C10 to C14 alkylamines (BASF AG, 2005; normalized to 100%):

- C10 -amines: 1%

- C11- amines: 12%

- C12 -amines: 16%

- C13 -amines: 68%

- C14 -amines: 3%

The main fraction with an amount of approximately 70% are C13 isomers. For this fraction 1-Tridecanamine (CAS 2869 -34 -3) was selected as representative C13 substance. The assessment of ecotoxicology is predominantly focused on this molecule, especially in case of calculations and non-BASF studies.

Short-term toxicity to fish:

Acutely very toxic to fish (96 -h LC50 = 0.065 mg/L, based on measured test item concentrations).

 

Short-term toxicity to aquatic invertebrates:

Acutely very toxic to aquatic invertebrates (48 -h EC50 = 0.015 mg/L, based measured test item concentrations).

 

Growth inhibition to aquatic algae:

Acutely very toxic to aquatic algae (freshwater species: 72-h EC50 = 0.015 mg/L, 72-h EC10 = 0.0032 mg/L; marine species: 96-h EC50 = 0.2 mg/L, all values are based on nominal concentrations).

 

Toxicity to microorganisms:

Depending on local and existing concentrations, disturbances in the biodegradation process of activated sludge are possible (30-min EC50 = 40 mg/L, based on nominal concentrations).
