Xab npum yog lub npe ntawm fatty acid hlau cov ntsev. Cov mis nyuj yog RCOOM, RCOO yog fatty acid thiab M yog hlau ion. Cov naj npawb ntawm cov kua qaub fatty nyob hauv txhua txhua hnub yog feem ntau yog 10-18. Cov hlau yog tsuas yog sodium los yog potassium thiab lwm yam alkali hlau. Nws kuj yog siv rau xab npum tshwj xeeb, xws li ammonia thiab ib co qauv hauv paus, xws li ethanolamine thiab triethanolamine. Feem ntau, fatty acids, xws li cov roj, waxes, rosin lossis fatty acids thiab alkaloids, uas yog saponified los yog neutralized, tuaj yeem hu ua xab npum. Xab npum yuav yaj nyob hauv dej, thiab nws muaj kev ua kom huv thiab kev txav deb. Xab npum muaj txhua hom tshuaj ntxuav tes, tseem hu ua xoom npab, tshuaj ntxuav tes thiab tshuaj ntxuav tes. Xab npum yog lub npe ntawm fatty acid hlau ntsev, pes tsawg tus roj naj npawb hauv txhua hnub yog feem ntau 10-18, hlau yog tsuas sodium lossis potassium thiab lwm yam alkali hlau, tab sis kuj tseem ceeb rau ammonia thiab ib co qauv organic xws li ethanolamine, triethanolamine thiab lwm cov tshuaj ntxuav tes tshwj xeeb. Xab npum muaj tshuaj ntxuav tais diav, xab npum, tshuaj ntxuav tes, xab npum, tshuaj ntxuav tes, tshuaj ntxuav ntsev, roj kua qaub, antioxidant, tus kabmob loj hlob, tus kabmob sclerosing, thickener, hluavtaws surfactant. Lub ntsiab ntawm cov tshuaj xub npum R-CO2Na (sodium stearate) (C17H35COONa), R pawg feem ntau yog qhov sib txawv, yog ntau hom pawg roj carbon. R- yog ib pawg neeg muaj roj hiam, thiab pawg carboxyl yog ib pab pawg neeg muaj roj (hydrophilic group).
