Kuwerengera kwazinthu zamatrix muzinthu zosamalira khungu (2)

Sabata yatha, tidakambirana za zida zopangira mafuta ndi ufa muzodzikongoletsera za matrix. Lero, tipitilizabe kufotokozera zida zotsalira za matrix: zida za chingamu ndi zosungunulira.

Colloidal zopangira - oteteza mamasukidwe akayendedwe ndi bata
Zipangizo za Glial ndizinthu zosungunuka za polima zosungunuka ndi madzi. Zambiri mwazinthuzi zimatha kufalikira kukhala colloid m'madzi kupanga ufa wolimba kukhala ndodo ndi mawonekedwe. Atha kugwiritsidwanso ntchito ngati emulsifiers kuti akhazikitse emulsions kapena kuyimitsidwa. Kuphatikiza apo, amatha kupanganso mafilimu ndikuwonjezera gel. Zipangizo za glial zomwe zimagwiritsidwa ntchito muzodzola zimagawidwa makamaka m'magulu atatu: zachilengedwe ndi zopangira, ndi semi synthetic.

Mankhwala a polima osungunuka m'madzi: nthawi zambiri amachokera ku zomera kapena zinyama, monga wowuma, chingamu (monga Arabic gum), gelatin ya nyama, ndi zina zotero. malo, ndipo pali chiopsezo choipitsidwa ndi mabakiteriya kapena nkhungu.

Mankhwala opangidwa ndi polima osungunuka m'madzi, kuphatikiza mowa wa polyvinyl, polyvinylpyrrolidone, asidi wa polyacrylic, ndi zina zambiri, amakhala ndi zinthu zokhazikika, kupsa mtima kwapakhungu, komanso mitengo yotsika, motero amachotsa ma polima osungunuka m'madzi monga gwero lalikulu la zida za colloidal. Nthawi zambiri amagwiritsidwa ntchito ngati zomatira, zokhuthala, zopangira filimu, ndi emulsifying stabilizer mu zodzoladzola.

Semi synthetic water-soluble polymer compounds: Zomwe zimachitika kwambiri ndi methyl cellulose, ethyl cellulose, carboxymethyl cellulose sodium hydroxyethyl cellulose, guar chingamu ndi zotumphukira zake, ndi zina.

Zosungunulira zopangira - chinsinsi cha kusungunuka ndi kukhazikika

Zopangira zosungunulira ndizofunikira pamadzi ambiri amadzimadzi, phala, ndi paste based skincare formulations. Akaphatikizidwa ndi zosakaniza zina mu chilinganizo, amakhalabe ndi zinthu zina zakuthupi za mankhwalawa. Zomwe zimagwiritsidwa ntchito kwambiri zosungunulira mu zodzoladzola makamaka zimaphatikizapo madzi, ethanol, isopropanol, n-butanol, ethyl acetate, ndi zina zotero. Madzi ndi omwe amagwiritsidwa ntchito kwambiri popanga khungu.
