Igipimo cya parafini kiringaniye kigenga imyitwarire yo gushonga no gukonja bitewe no gukonjesha, ibintu bibiri by'ingenzi bigira ingaruka ku miterere ya nyuma y'imiterere y'ibishashara byo gucukura. Urugero, imiterere ifite igipimo cya parafini gito ishobora kugaragaza kugabanuka kw'umurongo cyangwa ingano, bigira ingaruka ku ireme ry'ibihumyo no ku gucukura hasi. Kugumana ubu buringanire byongera umusaruro wo gucukura ibishashara no kohereza ibisobanuro ku buso.
Guhitamo inyongeramusaruro—cyane cyane ikoreshwa rya aside stearic—byuzuza igenzura ry’ikigereranyo cya parafini mu gutunganya imikorere y’uruvange rw’ibishashara. Aside stearic ihindura kristali, iteza imbere kristali nini kandi nini zitanga ubushobozi bwo gukora neza no gukata. Hamwe n’uruvange rw’aside stearic na parafini, gukoresha neza uru ruvange ntibyongera imbaraga za mekanike gusa ahubwo binatuma inzira yo gukaraba ihinduka. Iyo bikozwe neza, uru ruvange rutanga imiterere isuku kandi igatuma ubuso butunganywa neza. Ariko, iyo aside stearic igabanutse cyane, hashobora kubaho ingaruka mbi za shimi (nk’isaponification), bigatuma ubuso bukomera ndetse no kwangirika kw’ibihumyo.
Ishingiro ry'ibi bikoresho ni uburyo bukomeye bwo kugenzura ubuziranenge. Uruvange rugomba gupimwa buri gihe kugira ngo harebwe niba ingano yarwo ingana kandi hamenyekane ko rwanduye hakoreshejwe irangi cyangwa uduce duto. Amasezerano agezweho asaba isesengura rya laboratwari—hakoreshejwe uburyo nka chromatography ya gaze na differential scanning calorimetry kugira ngo hamenyekane imiterere y'ibikumwe—ndetse no gupima imiterere y'ibintu by'ingenzi nk'aho bishonga n'ubushyuhe. Ibipimo by'umubiri bihoraho bigaragaza ko uruvange ari rumwe, rushyigikira imiterere ihamye no gukumira inenge.
