1. Kumvetsetsa lingaliro la "kunyowetsa" mafuta m'thupi
Mafuta oyera samadzimadzi kwenikweni m'lingaliro lowonjezera madzi. Amathandiza kuchepetsa kutaya madzi m'thupi (TEWL), komwe ndi kutuluka kwa madzi kuchokera pakhungu. Kuti chinthucho chikhale chonyowa kwenikweni, tiyenera kuphatikiza humectant (monga glycerin) kapena kugwiritsa ntchito njira ya "oil-gel" yomwe ingathe kunyamula humectant komanso madzi ochepa. Apa pali vuto: mafuta ndi madzi sizimasakanikirana popanda thandizo la emulsifier kapena solubilizer.
Pali njira ziwiri zodziwika bwino:
1) Mafuta a thupi opanda madzi (opanda madzi)
Yokhazikika komanso yosavuta kupanga. Mphamvu zake zopatsa mphamvu zimachokera ku njira yogwiritsira ntchito (yogwiritsidwa ntchito pakhungu lonyowa) komanso kuwonjezera zosakaniza monga squalane, ma ceramides osungunuka mafuta, kapena mafuta omwe amalimbitsa chotchinga cha khungu.
2) Mafuta a thupi la Biphasic kapena emulsion yopepuka (ili ndi gawo laling'ono la madzi + humectant)
Zimapereka mphamvu zambiri chifukwa cha kupezeka kwa zinthu zosungunulira. Komabe, zimafuna zinthu zosungunulira/zosungunulira, zosungira, komanso njira zowuma zoukhondo.
Ngati ndinu woyamba, yambani ndi mtundu wa anhydrous poyamba, kenako pitani ku mtundu wa biphasic mukamakhala omasuka.

C. Zosakaniza zonyowetsa (zopatsa mphamvu) zomwe zingagwiritsidwe ntchito
– Glycerin: chinthu chodziwika bwino chosungunula madzi, chogwira ntchito bwino, koma chimafuna madzi/chosungunula kuti chikhale chomasuka.
– Propanediol: humectant ndi solvent, yopepuka kuposa glycerin.
– Sodium PCA / Panthenol: imanyowetsa madzi kwambiri, koma imachokera m'madzi—yoyenera kwambiri pa emulsion formulas.
D. Zipangizo zothandizira
Vitamini E (Tocopherol): antioxidant yomwe imachepetsa kukhuthala kwa mafuta.
– Mafuta onunkhira/ofunikira (ngati mukufuna): amapereka fungo labwino; gwiritsani ntchito mosamala komanso mosamala pakhungu losavuta kugwiritsa ntchito.
– Emulsifier/solubilizer (ya mtundu wa biphasic): mwachitsanzo polysorbate kapena PEG-derivatives zomwe zimapangidwa kuti ziphatikize mafuta ndi madzi.
– Zosungira (zofunikira ngati pali madzi): mwachitsanzo zosungira zambiri zomwe zimagwirizana ndi malamulo ndi mlingo.
