Conclusion on classification

Dicyclohexyl phthalate has been investigated for acute aquatic toxicity in fish (result LC50 (96h, Oryzias latipes) > 2 mg/l), in daphnia (result EC50 (48h daphnia magna) > 2 mg/l) and algae (result EC50 (72h, Pseudokirchnerella subcapitata) > 2 mg/l), the substance is readly biodegradable and has a BCF of 85 therefore it can not be classified for acute aquatic toxicity.

Based on the result of a chronic study on Daphnia magna, 21 days NOEC = 0.181 mg/L the substance meet the criteria for classification according to Regulation (EC) No 1272/2008, Annex I section 4.1 as amended by Regulation (EC) No 286/2011, as follow:

- GHS category: Aquatic Chronic 3

- GHS pictogram: no pictogram is used

- Signal Word: no signal word is used

- Hazard Statement: H412, Harmful to aquatic life with long lasting effects
