IHydroxyethyl Cellulose (HEC) sisithako sekhemikhali esiqhele ukusetyenziswa kwiimveliso zokhathalelo lwesikhumba. Yinto ephuma kwi-cellulose kwaye inokuqina kakuhle kunye nokuzinza. Isetyenziswa kakhulu kwizinto zokuthambisa, izinto zokuthambisa, izicoci, kunye nezinye iimveliso zokhathalelo lolusu ikakhulu ngenxa yokuncamathela kwayo, ukuziva okusilika, kunye neempawu zokufuma. Nangona ingenawo ngokuthe ngqo umsebenzi obalulekileyo we-pharmacological okanye iipropati zokuphulukisa ngokwayo, ukusetyenziswa kwayo kwiimveliso zokunakekelwa kwesikhumba kunempembelelo ebalulekileyo kwinduduzo yesikhumba kunye nokuthungwa kwemveliso.
1. Indima ye-thickeners kunye ne-stabilizers
IHydroxyethylcellulose isetyenziswa kakhulu kwiimveliso zokhathalelo lwesikhumba njengento etyebisayo kunye nokuzinzisa. Injongo ye-thickener kukunceda imveliso igcine ukuthungwa okufanayo, ukuthintela ukugqithiswa okanye ukuhlukana, kunye nokwenza imveliso ibe lula ukuyisebenzisa kunye nokufunxa. Ekubeni iimveliso ezininzi zokunakekelwa kwesikhumba (ezifana ne-lotions, i-gels, i-creams, njl.) Ziqulethe amanzi kunye neoli, i-hydroxyethyl cellulose inokunceda ezi zithako zidibanise ngokuzinzileyo kwaye zinike amava okusebenzisa kakuhle. Esi sakhiwo esizinzile sinokuthintela iimveliso zokunakekelwa kwesikhumba ukuba zingaboli ngexesha lokugcinwa, ukuphucula ubomi beshelufu kunye nokusebenza kwemveliso.
2. Ukuphucula amava okusetyenziswa
Iselulosi yeHydroxyethyl ineempawu ezithile zokufuma. Inokwenza ifilimu encinci ekhuselayo ukunceda ulusu lugcine ukufuma. Esi sithako sihlala sisetyenziswa kwiimveliso zokhathalelo lwesikhumba kunye neefomyula ezingenawo ioli ukubonelela ukuthungwa okugudileyo kunye nokukhululeka ngaphandle kokongeza i-greasiness. Inokwenza ukusetyenziswa kweemveliso zokunakekelwa kwesikhumba kube lula, ukuphucula ngokufanelekileyo amava esicelo semveliso, kwaye wenze inkqubo yokunakekelwa kwesikhumba ibe mnandi ngakumbi.
3. Ubuhlobo kwisikhumba esibucayi
IHydroxyethylcellulose yinto ethambileyo, ethobayo, iyenza ilungele zonke iintlobo zolusu, kubandakanya ulusu olubuthathaka. Ayinakwenzeka ukubangela ukusabela okanye ukucaphuka, ngoko inokufumaneka kwiifomula ezininzi ezinobuthathaka. Oku kwenza i-hydroxyethylcellulose ibe lolona khetho lufanelekileyo kubantu abaninzi abanezithintelo zolusu ezisengozini okanye ezibuthathaka. Esi sithako sikwasetyenziswa rhoqo kukhathalelo lomntwana kunye neemveliso zokucoca ulusu olubuthathaka kuba luthambile kwaye luyi-hypoallergenic.
4. Ukukhuthaza iimpawu zokuthambisa zemveliso
Nangona i-hydroxyethylcellulose ngokwayo ayisiyiyo i-moisturizer eyomeleleyo, inokunceda ukunciphisa ukulahleka komswakama esikhumbeni ngokwenza ifilimu ekhuselayo. Esi siphumo sesithintelo sifanelekile ngokukodwa kwesikhumba esomileyo kwaye xa iimeko zokusingqongileyo zinzima (ezifana nokubanda okanye imozulu eyomileyo). Xa idibaniswe nezinye izithako ezithambisayo (ezifana ne-glycerin, i-hyaluronic acid, njl.), i-cellulose ye-hydroxyethyl inokuphucula umphumo wokunyusa kwaye incede ulusu luhlale luthambile kwaye lunamanzi.
5. Akukho iimpawu zezithako ezisebenzayo
Nangona i-hydroxyethylcellulose inokuzisa imvakalelo ekhululekile yokusetyenziswa kunye nefuthe elithile lokuthambisa, akusiyo into esebenzayo, oko kukuthi, ayisebenzi ngokuthe ngqo kunye neeseli zesikhumba okanye ikhuthaze ukulungiswa kwesikhumba kunye nokuvuselelwa. Ke ngoko, indima ye-hydroxyethyl cellulose kwiimveliso zokhathalelo lwesikhumba ingaphezulu kokubonelela ngokucokisekileyo kwemveliso kunye nokuziva kwesicelo esithambileyo, kunokusombulula ingxaki ethile yesikhumba (efana nemibimbi, ibala okanye i-acne).
6. Ukunciphisa ukucaphuka kwesikhumba
Izithako ezisebenzayo kwezinye iimveliso zokhathalelo lolusu (ezifana neeasidi, izinto eziphuma kwivithamin A, njl.njl.) zinokubangela ukucaphuka eluswini, ngakumbi ulusu olubuthathaka. I-Hydroxyethyl cellulose inokunciphisa ngokufanelekileyo ukucaphuka kwezi zithako ezisebenzayo eluswini. Isebenza njenge-matrix engasebenziyo ukunceda ukumodareyitha iziphumo ezinamandla zezithako ezisebenzayo ngelixa ugcina ukusebenza kwemveliso.
7. I-Ecology kunye nokhuseleko
I-Hydroxyethyl cellulose yimathiriyeli ekwazi ukubola eyenziwe ngesityalo se-cellulose kwaye ihambelana nokusingqongileyo. Oku kuthetha ukuba ayisayi kuba neziphumo ezibi ezihlala zihleli kwi-ecosystem emva kokusetyenziswa njengekhemikhali zokwenziwa. Ukongezelela, ezininzi zedermatologists kunye neengcali zokunakekelwa kwesikhumba zijonga njengento ekhuselekileyo yokusetyenziswa kwexesha elide.
Indima ye-hydroxyethyl cellulose kwiimveliso zokunakekelwa kwesikhumba ibonakala ngokukodwa ekuphuculeni ukuthungwa, umphumo wokuthambisa kunye nokuzinza kwemveliso. Nangona ingaziphathi iingxaki zesikhumba nge-se, ilungele zonke iintlobo zolusu, ngakumbi ulusu olubuthathaka, ngenxa yokucaphuka okuphantsi, iipropathi ezithambileyo kunye neempawu ezintle zokuthambisa. Kwangaxeshanye, inceda ezinye izithako kwimveliso ukusebenza ngcono eluswini, ukunciphisa ukucaphuka ukuba izithako ezisebenzayo kunokubangela. Ke ngoko, ukusetyenziswa kwe-hydroxyethyl cellulose kwiimveliso ezininzi zokhathalelo lwesikhumba kubonelela abasebenzisi ngamava amnandi ngakumbi okhathalelo lwesikhumba kwaye negalelo ekugcineni ukufuma kunye nentuthuzelo.
