Conclusion on classification

According to the Annex VI of the REACh regulation 1,3-diphenylguanidine is classified as toxic to aquatic life with long-lasting effects (Aquatic chronic 2).


According to GHS-UN, the results below are conclusive and so show that 1,3-diphenylguanidine is classified in the acute category 2 (Toxic to aquatic life) and chronic category 3 (harmful to aquatic life with long lasting effects).


* Short term Toxicity to Fish:LC50-96h = 4.2 mg/l


* Short term toxicity to aquatic invertebrates:EC50-48h = 17 mg/L .


* Toxicity to aquatic algae:EC50-72h= 1.4 – 1.7 mg/L .


* Toxicity to aquatic micro-organisms:EC50-3h=147 mg/L 


* 1 ,3-diphenylguanidine is readily biodegradable
