Additional information
Sodium diisobutylnaphtalene sulphonate resulted of moderate toxicity for aquatic organisms basing on the lowest eco-toxicity value in Daphnia magna (EC50of 64 mg/L). Considering the inherently biodegradation of the substance, which involves a first order biodegradation, the substance may be considered harmful for aquatic environment with long-lasting effects.
Conclusion on classification
According to Regulation 1272/2008/EC, Sodium diisobutylnaphtalene sulphonate is classified for Aquatic Toxicity class in category 3, H412.
