Conclusion on classification

Dibutyl hydrogen phosphate is not legally classified as dangerous for the environment and so neither included in Annex I of Directive 67/548/EEC nor in Regulation 1272/2008 (CLP), including its 16th ATP.

According to the information summarised in this chapter, dibutyl hydrogen phosphate should not be classified for the following reasons:

- The acute toxicity values are all above 100 mg/l representing three trophic levels obtained in short-term toxicity tests towards algae, fish and Daphnia.

- The most sensitive long-term toxicity is to algae with a 72h-EC10 of 76 mg/l

- Dibutyl hydrogen phosphate is not readily biodegradable

- The bioaccumulation potential is assessed in a bioconcetration study on fish. BCF values of <6.9 were determined, indicating a very low potential for bioaccumulation. This is in agreement with the log Kow values of -0.90 and 2.29 for the dissociated and non-dissociated from of dibutyl hydrogen phosphate.
