Bismuth oxide salicylate

Endpoint summary

Additional information

Abiotic degradation

The term ‘Hydrolysis’ refers to the “Decomposition or degradation of a chemical by reaction with water”, and this as a function of pH (i.e., abiotic degradation). In the case of metals like bismuth the chemical safety assessment is generally based on total elemental metal concentrations, regardless of their (pH-dependent) speciation in the environment. Therefore, physicochemical processes like degradation or transformation by reaction with water are judged not relevant for the bismuth component of bismuth subsalicylate.

Biotic degradation

By read-across from salicylic acid, the subsalicylate component of the substance is considered to be inherently biodegradable. The concept of biodegradability does not apply to the bismuth component of bismuth subsalicylate.
