Description of key information
Aluminium tributanolate dissociates instantaneously when exposed to water forming butan-1-ol and aluminium(III) species. Therefore the effects of both hydrolysis products are considered most relevant to assess the toxicity of aluminium tributanolate.
In a test according to OECD 202, the EC50 of aluminium chloride in daphnia magna was found to be 3.9 mg Al/L (Okamoto 2015). In a review of acute toxicity test on several marine species the LC50 varied between 97 and 10000 ug/L (Golding 2015)
For butanol the 24 hour EC50 was determined by means of a standardized procedure using 24-h-old animals from a clone of Daphnia magna at 1855 mg/L.

Additional information
Aluminium tributanolate reacts instantaneously with water to form butan-1-ol and Al3+ species. The resulting pH being weakly alkaline indicates according to Langmuir et al. 2004 that Al3+ species formed are mainly Al(OH)4-, Al(OH)3 and Al(OH)2+ at pH 8.5.
Aluminium tributanolate is abiotically degradable and forms butanol being readily biodegradable as shown in several publications (Bridie 1979, Price 1974).
Hence, both butanol and aluminium species will be present in aqueous media. Based on its toxicity, aluminium species seem to represent a worst case surrogate for assessing toxicity to aquatic species exposed to the substance, aluminium tributanolate.
