Nkọwa ngwaahịa
Sodium stearate bụ nnu sodium nke stearic acid. Nke a siri ike na-acha ọcha bụ ncha a na-ahụkarị. A na-achọta ya n'ọtụtụ ụdị deodorants siri ike, rọba, agba latex, na ink. Ọ bụkwa akụkụ nke ụfọdụ ihe mgbakwunye nri na ihe ụtọ nri. Àgwà nke ncha, sodium stearate nwere ma hydrophilic na hydrophobic akụkụ, na carboxylate na ogologo hydrocarbon yinye, karị. Ihe abụọ a dị iche iche nke kemịkalụ na-eme ka e guzobe micelles, nke na-enye ndị isi hydrophilic n'èzí na ọdụ ha hydrophobic (hydrocarbon) n'ime, na-enye ebe obibi lipophilic maka ogige hydrophobic. Akụkụ ọdụ ahụ na-agbaze griiz (ma ọ bụ) unyi na-emepụta micell. A na-ejikwa ya na ụlọ ọrụ ọgwụ dị ka onye na-emepụta ihe iji nyere aka solubility nke ogige hydrophobic na mmepụta nke ọnụ ọnụ dị iche iche.
