Additional information
Conclusion on classification
Short-term toxicity to fish:
Oncorhynchus mykiss; OECD TG 203; read-across.
96-h LL50 value of greater than 100 mg/L loading rate WAF
Short-term toxicity to aquatic invertebrates:
Daphnia magna; OECD TG 202. Read-across
48-h EC50 > 5.62 mg/L (measured) (100 mg/L nominal loading rate WAF)
Toxicity to aquatic algae:
Pseudokirchneriella subcapitata; OECD TG 201. Read-across
Results based on initial nominal loading rates (WAFs):
72 -h ErL50 > 100 mg/L; 72 -h NOErLR = 12.5 mg/L
Results based on initial measured concentrations:
72 -h ErC50 > 28.92 mg/L; 72 -h NOErC = 6.53 mg/L
The parent alcohol, Alcohols, C11-14 - iso-, C13-rich, is classified as Acute Aquatic 1 (H400), Acute Chronic 2 (H411). According to the Summation method specified Annex I: 4.1.3.5.5.3.1 of CLP, if a mixture contains > 25% of components classified as Acute 1, then the mixture is classified as Acute 1. The alcohol is present at 20 -40% w/w and therefore the Acute 1 classification is applied to all qualities. Similarly, according to 4.1.3.5.5.4.2, if a mixture is not classified as Chronic 1 and contains >25% of components classified as Chronic 2, then the mixture is classified as Chronic 2. The alcohol is present at 20 -40% w/w and therefore the Chronic 2 classification is applied to all qualities.
