Zolembera zokhazikika ndi mtundu wa cholembera.Zapangidwa kuti zizikhala kwa nthawi yayitali komanso kukana madzi.Kuti achite izi, amapangidwa kuchokera ku mankhwala osakaniza, utoto, ndi utomoni.Mukhoza kusankha mitundu yosiyanasiyana.
Poyambirira, iwo anapangidwa kuchokera ku xylene, chochokera ku petroleum.Komabe, m’zaka za m’ma 1990, opanga inki anasintha n’kuyamba kumwa mowa wopanda poizoni.
Zolembera zamtundu uwu zimagwira pafupifupi zofanana pamayeso.Kupatula mowa, zigawo zikuluzikulu ndi utomoni ndi colorant.Utotowu ndi polima wofanana ndi guluu womwe umathandiza kuti utoto wa inki ukhale m'malo pamene zosungunulirazo zasanduka nthunzi.
Nkhumba ndi mtundu womwe umagwiritsidwa ntchito kwambiri pazolembera zokhazikika.Mosiyana ndi utoto, iwo sagonjetsedwa ndi kusungunuka ndi chinyezi ndi zinthu zachilengedwe.Komanso si polar, kutanthauza kuti samasungunuka m'madzi.
