Abstract
New polyethoxylated tertiary amines were synthesised and applied as Switchable Hydrophilicity Solvents (SHS) in the extraction and recovery of lipids from algal cultures, bypassing harvesting and de-watering steps. The eco-toxicological profile of the new amines was explored by evaluating their potential in inhibiting algal growth, and deepened by measuring the acute toxicity towards the crustacean Daphnia magna and the ready biodegradability in water. Among the synthesised amines, the one bearing two ethoxy units, named amine 2, showed the best combination in terms of lipids' extractive performances and toxicity; therefore it could be considered as a good alternative to N, N-dimethylcyclohexylamine (DMCHA), at the moment the most studied and effective SHS.
