TL;DR: Their efficiency as antimicrobial agents increased with the hydrophobicity of the amphiphilic cation being the C(14) homologous the most active compounds.

TL;DR: As compared to simple alkyl chain containing ILs bearing the same hydrocarbon chain, ester-functionalized ILs possess higher adsorption efficiency and significantly lower critical micelle concentration (cmc) and surface tension at the cmc (γ(cmc), indicating that the incorporation of an ester group promotes adsorptive at the air/water interface and micelle formation.

TL;DR: The degradation of these compounds in coastal waters was associated with an increase in bacterioplankton density, suggesting that the degradation takes place because the compound is used as a growth substrate.

TL;DR: The anaerobic biodegradability and toxicity to methanogenic gas production of different alkyl chain length homologs of quaternary ammonium based surfactants were examinated and showed a very poor primary biodegrading and no evidence of any extent of ultimate biodegradation was observed.

TL;DR: The increase of hydrophobicity in the bis(Args) is a negative structural parameter for their environmental behavior, and the molecules with a spacer chain < or =6 methylene groups can be considered as ready biodegradable.
