Biodegradability
Vim lub ntim loj ntawm surfactants tso rau hauv ib puag ncig, lawv cov biodegradability tau nyiam. Qee cov surfactants tuaj yeem decompose nyob rau hauv aerobic tej yam kev mob, tab sis ib txhia yuav decompose los tsim endocrine disruptors xws li nonylphenol. Kev tshawb fawb ntawm biodegradable surfactants tau txhawb txoj kev loj hlob ntawm "biosurfactants".
Environmental txaus ntshai
Nyob rau hauv cov concentrations siab heev, surfactants yuav ua rau muaj kev pheej hmoo ntawm ib puag ncig thaum ua ke nrog ntau cov hlau, tab sis ntawm cov concentrations tsawg, lawv daim ntawv thov tsis zoo li yuav muaj kev cuam tshuam loj rau kev tsiv teb tsaws ntawm cov kab hlau. Piv txwv li, hauv Deepwater Horizon roj nchuav, cov khoom xyaw nquag hauv Corexit, xws li sodium dioctylsulfosuccinate (DOSS), sorbitol monooleate (Span80), thiab polyoxyethylene sorbitol monooleate (Tween-80), tau txau ntau ntau rau hauv qhov chaw xau thiab dej hiav txwv dej los pab txhawb kev zom cov roj, tab sis kuj tau ua rau muaj kev txhawj xeeb txog lawv cov kev cuam tshuam ib puag ncig.
