Imiti
Sodium stearate ni ifu yera, ndumiwe gato mumazi akonje, kandi uhungabanye vuba mumazi ashyushye, kandi ntabwo arira nyuma yo gukonja cyane. Ifite ubwiza buhebuje, bwinjira kandi igambiriye imbaraga, ifite amavuta yumve, kandi afite impumuro nziza. Birashobora gushonga byoroshye mumazi ashyushye cyangwa amazi ya alcool, nigisubizo ni alkaline kubera hydrolysis.

Ibisobanuro
Sodium stearate ni umunyu wa sodium wa aside iriya, uzwi kandi nka octadecate octadecate, nikintu gikunze gukoreshwa aiyoni na anioctic bikunze kugaragara hamwe nibigize amasasu. Modrocarbybylywl Moient muri sodium stearate molekile ni itsinda rya hydrophobic, kandi urugomero rwa carboxyl ni itsinda rya hydhilic. Mu mazi y'itonga, sodium stearate ibaho muri miselles. Miselles ni iz'imibare kandi igizwe na molekile nyinshi. Amatsinda ya Hydrophobic arahazarure kandi ahujwe na mugenzi wawe wa van Waals imbaraga, kandi amatsinda ya hydrophilic ni hanze kandi akwirakwizwa hejuru ya miseli. Miseli yatatanye mumazi, kandi mugihe cyo guhura namavuta yamavuta yamazi meza, amavuta arashobora gutatanya ibitonyanga byiza byamavuta. Itsinda rya Hydrophobic rya sodium risenyuka mumavuta, mugihe itsinda rya hydrophilique ryahagaritswe mumazi ryo kugabanuka. Mu mazi akomeye, shyira iveon uremo hamwe na calcium na magnesium ion kugirango bakore calcium yamazi hamwe na magnesium, bigabanya ibintu byihutirwa. Usibye sodium stearate, isabune irimo sodium palmitate ch3 (ch2) 14coona na sodium yubaroma ba acide acide (C12-C20).
