Two aquatic toxicity tests published in peer review journals are available.
Both studies presented tests with the freshwater invertebrates, Daphnia magna, according to standardized guidelines. In the condition of these studies, Trihexyltetradecylphosphonium chloride caused adverse effects on daphnids with an EC50-48h key value of 0.053 mg/L.
One study presented a test with the freshwater algae Pseudokirchneriella according to a standardized guideline. In the condition of these studies, Trihexyltetradecylphosphonium chloride caused adverse effects on algae with an EC50-48h value of 0.042 mg/L.
Based on this information, Trihexyltetradecylphosphonium chloride is considered as:
-Very toxic to aquatic life (Aquatic acute tox. 1) (CLP and UN classifications).
-Very toxic to aquatic life with long lasting effects (Aquatic chronic tox. 1) (CLP and UN classifications)
