Kwagura urunigi na emulisiferi yo gukwirakwiza amazi ya polyurethane.Ni umunyu wa alifatique diamine sulfonic acide sodium yumunyu, ukoreshwa nkuwagura hydrophilique cyangwa monomer hydrophilique mugutegura resin polyurethane ikomoka mumazi, ibereye gutwikirwa, wino, ibifunga hamwe nibikoresho byo kurangiza uruhu nizindi nganda.Sodium Ethylenediaminoethanesulfonate irashobora kandi gukoreshwa mubindi bice nkumuhuza w’ibinyabuzima na reagent ya biohimiki.X-imyanya yayo hamwe nu mwanya wa kabiri amatsinda amatsinda arashobora kwitwara hamwe nitsinda rya isocyanate kandi akenshi birasabwa gukoreshwa mugikorwa cya acetone.Ikwirakwizwa rya polyurethane ikomatanyije ukoresheje umunyu wa AAS ifite hydrolytike nziza kandi ihuza neza nandi mazi ya anionic cyangwa nonionic.
