Kwiveki ephelileyo, sithethe ngezinto ezisekwe kwi-oyile kunye nomgubo kwizinto zokuthambisa zematrix. Namhlanje, siya kuqhubeka nokuchaza izinto eziseleyo ze-matrix: izixhobo zegum kunye nezixhobo zokunyibilikisa.
Izinto eziluhlaza ze-Colloidal - abagcini be-viscosity kunye nokuzinza
Imathiriyeli ekrwada yeGlial ziikhompawundi zepolymer ezinyibilikayo emanzini. Uninzi lwezi zinto zinokukhula zibe yicolloid emanzini ukwenza intonga eqinileyo yomgubo. Zisenokusetyenziswa njengeemulsifiers ukuzinzisa emulsions okanye ukumiswa. Ukongeza, banokwenza iifilimu kwaye batyebe ijeli. Izixhobo ze-glial ekrwada ezisetyenziswa kwizithambiso zohlulwe kakhulu zibe ziindidi ezintathu: ezendalo kunye nezokwenziwa, kunye ne-semisynthetic.
Iikhompawundi zepolymer zendalo ezinyibilikayo emanzini: zidla ngokuphuma kwizityalo okanye kwizilwanyana, ezifana nesitatshi, itshungama yezityalo (ezifana nentlaka yesiArabhu), igelatin yezilwanyana, njl. njl. indawo yejografi, kwaye kukho umngcipheko wokungcoliswa yibhaktheriya okanye ngundo.
I-synthetic water-soluble polymer compounds, kuquka i-polyvinyl alcohol, i-polyvinylpyrrolidone, i-polyacrylic acid, njl., inezakhiwo ezizinzileyo, ukucaphuka kwesikhumba esincinci, kunye namaxabiso aphantsi, ngaloo ndlela ithatha indawo yendalo ye-polymer e-soluble yamanzi njengomthombo oyintloko we-colloidal materials. Ihlala isetyenziswa njenge-adhesive, thickener, agent-forming agent, kunye ne-emulsifying stabilizer kwi-cosmetics.
Iikhompawundi ze-polymer ze-semi synthetic ezinyibilikayo zamanzi: Ezona ziqhelekileyo ziquka i-methyl cellulose, i-ethyl cellulose, i-carboxymethyl cellulose i-sodium hydroxyethyl cellulose, i-guar gum kunye ne-derivatives yayo, njl.
Izinto ezinyibilikayo ekrwada - isitshixo sokunyibilika nokuzinza
Imathiriyeli ekrwada enyibilikayo zizinto eziyimfuneko kulwelo oluninzi, intlama, kunye nokuncamathelisa iifomyula zokhathalelo lwesikhumba. Xa zidibene nezinye izithako kwifomula, zigcina iimpawu ezithile zomzimba zemveliso. Izinto ezisetyenziswa ngokuqhelekileyo ze-solvent kwi-cosmetics zibandakanya amanzi, i-ethanol, i-isopropanol, i-n-butanol, i-ethyl acetate, njl.
