IHydroxyethylcellulose (HEC) yipolymer engeyiyo-ionic yamanzi enyibilikayo esetyenziswa kakhulu kwiimveliso zokhathalelo lwesikhumba. Njenge-cellulose elungisiweyo, i-hydroxyethylcellulose yazisa amaqela e-ethoxy kwikhonkco ye-cellulose yendalo ye-molecular chain ukuze ibe nokunyibilika okulungileyo kunye nokuzinza emanzini. Imisebenzi yayo ephambili ekunyamekelweni kwesikhumba ibandakanya ukuqina, ukuthambisa, ukuzinzisa, kunye nokuphucula ukubamba kwemveliso.
1. Ukutyeba
Omnye weyona misebenzi ibalulekileyo ye-hydroxyethylcellulose kukutyebisa. Kwiimveliso zokunakekelwa kwesikhumba ezifana ne-lotions, i-creams, izicoci kunye neegels, indima ye-thickeners kukwandisa i-viscosity kunye nokuhambelana kwemveliso, okwenza kube lula ukuyifaka kunye nokugcina phezu kwesikhumba, ngaloo ndlela kuphuculwe amava okusetyenziswa kwemveliso. I-Hydroxyethylcellulose inokwenza isisombululo se-colloidal esifanayo ngokufunxa amanzi kunye nokudumba, ngaloo ndlela ikhulise i-viscosity yefomyula, kwaye le mpembelelo yokuqina ayichatshazelwa yi-electrolytes, ngoko inokuthi ibekho ngokuzinzileyo kwiintlobo ezahlukeneyo zeefomula.
2. Isiphumo sokuthambisa
Ekunyamekelweni kwesikhumba, ukuthambisa ngumsebenzi obaluleke kakhulu, kwaye i-hydroxyethyl cellulose nayo inegalelo kulo mbandela. Iyakwazi ukufunxa kwaye igcine umlinganiselo othile wamanzi, yenze umqobo wokuthambisa ukuthintela ukulahleka okugqithisileyo kokufuma kumphezulu wolusu. Xa isetyenziswa ngokudibeneyo nezinye izinto zokuthambisa, i-hydroxyethyl cellulose inokunceda ukutshixa ukufuma, ukwandisa ixesha lokunyakamisa, kunye nokugcina ulusu luthambile kwaye lugudile emva kokusetyenziswa.
3. Isizinzi
I-Hydroxyethyl cellulose ikwasebenza njengesizinzisi ukunceda ukuthintela ukuhluzwa kwemveliso okanye imvula. Kwiimveliso ezininzi ze-emulsified, ezifana ne-lotions okanye i-creams, ukuzinza phakathi kwesigaba samanzi kunye nesigaba seoli kubalulekile. I-cellulose ye-Hydroxyethyl inokuphucula ukuzinza kwenkqubo ye-emulsified kunye nokwandisa ubomi beshelufu yemveliso ngokunyusa i-viscosity yenkqubo kunye nokuthintela ukuchithwa kwezithako.
4. Phucula imveliso touch
Kwiimveliso zokunakekelwa kwesikhumba, ukuthintela yinxalenye ebalulekileyo yamava omthengi. Iselulosi yeHydroxyethyl inokunika imveliso ukukhanya kunye nesilika ngaphandle kokushiya imvakalelo encangathi okanye enamafutha. Ngoko ke, isetyenziswa rhoqo kwiimveliso ezifuna ukuhlaziya kunye nokuchukumisa ukukhanya, njengama-gel kunye ne-lotions eziqabulayo. Ukongeza, ukucaphuka okuphantsi kunye nokuhambelana kakuhle kwesikhumba se-hydroxyethyl cellulose kuyenza ilungele iimveliso zokhathalelo lwesikhumba.
5. Ukuphucula ukusebenza kwemveliso
Ukongeza kule misebenzi ingentla, i-hydroxyethyl cellulose inokuphucula ukufana kokusabalalisa izithako ezisebenzayo, ukuqinisekisa ukuba izithako ezisebenzayo zingasasazwa ngokulinganayo kwindawo yesikhumba, ngaloo ndlela iphucula umphumo opheleleyo wemveliso. Ngokomzekelo, kwiifomyula eziqukethe i-antioxidants, izithako ze-antibacterial okanye izithako ezimhlophe, ukusetyenziswa kwe-cellulose ye-hydroxyethyl kunokunceda ezi zithako zisebenze ngokufanelekileyo.
6. I-Hypoallergenicity
Njengesixhobo se-polymer engeyiyo i-ionic, i-hydroxyethyl cellulose ine-allergenicity ephantsi kunye nokucaphuka okuphantsi ngenxa yesakhiwo sayo sekhemikhali, ngoko ke isetyenziswa ngokubanzi kwiimveliso zokunakekelwa kwesikhumba. Kubantu abaqhelene nokuchasana nezinto okanye izithintelo zolusu ezonakalisiweyo, i-hydroxyethyl cellulose lukhetho olukhuselekileyo nolusebenzayo.
7. Biodegradability
I-Hydroxyethyl cellulose yimveliso elungisiweyo evela kwi-cellulose yendalo, ngoko inokonakala okuhle kwe-biodegradability kunye nobuhlobo bendalo. Kwimeko yokwandiswa kwengqalelo yabathengi ekukhuselweni kwendalo kunye nophuhliso oluzinzileyo, iimveliso ezisebenzisa i-hydroxyethyl cellulose zinokwamkelwa okuphezulu kwimarike.
8. Ukuhambelana kwefomula
I-Hydroxyethyl cellulose inokuhambelana kakuhle kwefomula kwaye iyakwazi ukuhlala kunye neentlobo ezahlukeneyo zezithako ezisebenzayo, i-surfactants, i-emulsifiers, njl njl ngaphandle kokuphendula kakubi. Oku kuyenza isetyenziswe ngokubanzi kwiimveliso ezahlukeneyo zokunakekelwa kwesikhumba. I-Hydroxyethylcellulose inokudlala indima ezinzileyo kwiinkqubo zombini zesigaba samanzi kunye ne-oyile.
IHydroxyethylcellulose idlala iindima ezahlukeneyo kwiimveliso zokhathalelo lwesikhumba, ukusuka ekutyebeni nasekufumeni ukuya kuzinziso kunye nokuphucula ukubamba. Iquka phantse yonke imisebenzi ephambili ekuqulunqweni kweemveliso zokunakekelwa kwesikhumba. I-allergenicity ephantsi kunye nokuhambelana kakuhle kwesikhumba kwenza ukuba ibe yinto efanelekileyo kwiimveliso ezahlukeneyo zokunakekelwa kwesikhumba. Ubuhlobo bayo kokusingqongileyo kunye nokonakaliswa kwezinto eziphilayo kuhlangabezana nemfuno yangoku yemarike yeemveliso ezinobuhlobo nokuzinzileyo. Ngamafutshane, i-hydroxyethylcellulose ayiphuculi kuphela umgangatho weemveliso zokunakekelwa kwesikhumba, kodwa ihlangabezana nokulindelwe ngabathengi ekusebenzeni kakuhle kwemveliso kunye nokhuseleko.
