Chifukwa cha kupita patsogolo kwa anthu komanso kusintha kwa miyoyo ya anthu, anthu akusamala kwambiri za kusamalira khungu lawo komanso mawonekedwe awo. Kusankha zodzoladzola sikungokhala kokha pazinthu zosamalira tsiku ndi tsiku monga mafuta odzola, mafuta odzola, ndi mafuta odzola, ndipo kufunikira kwa zinthu zodzoladzola zamitundu kukukulirakulira. Zodzoladzola zamitundu zimatha kusintha ndikukongoletsa khungu mwachangu komanso moyenera. Komabe, titanium dioxide, mica, zinthu zopangira filimu, ma toner ndi zinthu zina zopangira zodzoladzola zamitundu sizimayamwa ndi khungu. Zimawonjezera katundu pakhungu, zomwe zimayambitsa mavuto monga khungu louma, ma pores akuluakulu, ziphuphu, utoto, khungu losawoneka bwino, ndi zina zotero, zomwe zimakhudza thanzi ndi mawonekedwe a khungu.

Pali mitundu yosiyanasiyana ya zodzoladzola zomwe zimagulitsidwa pamsika, monga madzi ochotsera zodzoladzola, mkaka wochotsera zodzoladzola, mafuta ochotsera zodzoladzola, zopukutira zodzoladzola, ndi zina zotero, ndipo magwiridwe antchito a mitundu yosiyanasiyana ya zodzoladzola ndi osiyana, ndipo zotsatira zotsuka za zodzoladzola nazonso ndi zosiyana.
Kutengera zaka zambiri zomwe wolembayo adakumana nazo pakufufuza ndi kupanga, nkhaniyi ikugawana njira, mfundo za njira yopangira, ndi njira yopangira chochotsera zodzoladzola.
Mafuta 50-60%, mafuta omwe amagwiritsidwa ntchito kwambiri ndi mafuta osungunula a isoparaffin, hydrogenated polyisobutylene, triglyceride, isopropyl myristate, ethyl oleate, ethylhexyl palmitate, ndi zina zotero. Mafuta omwe ali mu fomula amatha kusungunula zinthu zachilengedwe zosungunuka ndi mafuta mu zodzoladzola zotsalira, ndipo ali ndi mafuta abwino komanso opatsa thanzi kuti apewe khungu louma mutachotsa zodzoladzola.
Mankhwala opangidwa ndi surfactant 5-15%, omwe amagwiritsidwa ntchito kwambiri ndi anionic ndi nonionic surfactants, monga polyglycerol oleate, polyglycerol stearate, polyglycerol laurate, PEG-20 glycerin Triisostearate, PEG-7 Glyceryl Cocoate, Sodium Glutamate Stearate, Sodium Cocoyl Taurine, Tween, Span, ndi zina zotero. Mankhwala opangidwa ndi surfactant amatha kusakaniza zinthu zachilengedwe zosungunuka ndi mafuta ndi ufa wosapangidwa ndi zinthu zachilengedwe mu zinthu zodzoladzola zotsalira. Amagwiranso ntchito ngati emulsifier ya mafuta ndi mafuta mu zochotsa zodzoladzola.
Polyol 10-20%, ma polyol omwe amagwiritsidwa ntchito kwambiri ndi sorbitol, polypropylene glycol, polyethylene glycol, ethylene glycol, glycerin, ndi zina zotero. Amapangidwa ngati humectant.
Wothirira 0.5-1%, wothirira kwambiri ndikabomera, acrylic acid (ester)/C1030 alkanol acrylate cross-linked polymer, ammonium acryloyl dimethyl taurate/VP copolymer, acrylic acid hydroxyl Ethyl ester/sodium acryloyldimethyltaurate copolymer, sodium acrylic acid (ester) copolymer ndi sodium polyacrylate.
Njira Yopangira:
Gawo 1: kutentha ndi kusonkhezera madzi, surfactant yosungunuka m'madzi ndi polyol humectant kuti mupeze gawo la madzi;
Gawo 2: Sakanizani chosakaniza mafuta ndi mafuta kuti mupange gawo la mafuta;
Gawo 3: Onjezani gawo la mafuta ku gawo la madzi kuti mupange emulsify mofanana ndikukonza pH.
