Asidi Stearic chimagwiritsidwa ntchito zodzoladzola, plasticizers pulasitiki, wothandizila kumasulidwa, stabilizers, surfactants, mphira vulcanization accelerators, wothandizila madzi, wothandizila kupukuta, sopo zitsulo, zitsulo flotation, softeners, mankhwala, ndi mankhwala ena organic. Asidi wa Stearic angagwiritsidwenso ntchito ngati zosungunulira za inki zosungunuka zamafuta, mafuta opangira ma krayoni, opukuta pamapepala a sera, ndi emulsifier ya stearic acid glycerides.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
