I-Sodium Stearate ye-Anionic Surfactant kanye Nezinsipho

I-sodium stearate usawoti we-sodium we-stearic acid, owaziwa nangokuthi i-sodium octadecate, esetshenziswa kakhulu i-anionic surfactant kanye nengxenye eyinhloko yensipho.I-hydrocarbyl moiety ku-sodium stearate molecule iyiqembu le-hydrophobic, futhi i-carboxyl moiety iyiqembu le-hydrophilic.Emanzini anensipho, i-sodium stearate ikhona kuma-micelles.Ama-micelles ayindilinga futhi akhiwe ama-molecule amaningi.Amaqembu e-hydrophobic angaphakathi futhi ahlanganiswe namanye amabutho e-van der Waals, futhi amaqembu angama-hydrophilic angaphandle futhi asakazwa ebusweni bama micelles.Ama-micelles ahlakazeka emanzini, futhi lapho ehlangabezana namabala kawoyela angancibiliki emanzini, uwoyela ungahlakazwa ube amaconsi kawoyela amahle.Iqembu le-hydrophobic le-sodium stearate lincibilika kuwoyela, kuyilapho iqembu le-hydrophilic Limiswe emanzini ukuze lisuswe ukungcola.Emanzini aqinile, ama-ion e-stearate ahlangana ne-calcium ne-magnesium ions ukuze akhe i-calcium engancibiliki emanzini kanye nosawoti we-magnesium, okunciphisa ukubola.Ngaphezu kwe-sodium stearate, insipho iphinde ibe ne-sodium palmitate CH3(CH2)14COONA kanye nosawoti we-sodium wamanye ama-fatty acids (C12-C20).
