Description of key information

Hydrolysis:

In a study conducted in accordance with Directive 92/69/EEC, C.7, the hydrolysis of N,N-Didecyl-N-methylpoly(oxyethly)ammonium Propionate was assessed at a concentration of 4g/L in buffer solutions at pH 4, pH 7 and pH 9. Samples were incubated at 50°C for 5 days and shielded from light. No degradation occurred during the incubation period. N,N-Didecyl-N-methylpoly(oxyethly)ammonium Propionate is hydrolytically stable at 25°C at pH 4, 7 and 9 for over 1 year.

Phototransformation in water:

In a study conducted in accordance with U.S.EPA-FIFRA N-161-2, the photolysis rate of Didecyldimethylammonium Chloride was determined. The test substance (at a nominal concentration of 10 µg/ml was conducted at 25 °C in aqueous solution buffered at pH 7) was exposed to a xenon arc light source for 30 days and controls were kept in the dark for 30 days. The test substance is photolytically stable in the absence of a photosensitising agent. In the presence of the energy from a xenon arc lamp and the photosensitising agent, acetone, it appears that Didecyldimethylammonium Chloride breaks down to form a single degradate.

Based on the close similarities of this structural analog, didecylmethylpoly(oxyethyl)ammonium propionate is expected to undergo comparable phototransformation in water.
