Carbomer ma le hydroxyethylcellulose (HEC) o mea uma e masani ona faʻaaogaina i pisinisi eseese, aemaise lava i mea teuteu, vailaʻau, ma mea tau tausiga a le tagata lava ia. E ui lava ia latou faʻaoga tutusa e pei o vailaʻau mafiafia ma faʻamautu, e iai a latou vailaʻau faʻapitoa, meatotino, ma faʻaoga.
1. Fa'asologa o vaila'au:
Carbomer: Carbomers o polymers mamafa mole mole maualuga fa'ameamea ole acid acid e feso'ota'i fa'atasi ma polyalkenyl ethers po'o le divinyl glycol. E masani lava ona gaosia e ala i tali polymerization.
Hydroxyethylcellulose: O le Hydroxyethylcellulose, i le isi itu, o se mea e maua mai i le cellulose, o se polymer masani. E gaosia e ala i le togafitia o le cellulose i le sodium hydroxide ma le ethylene oxide e faʻafeiloaʻi ai vaega o le hydroxyethyl i luga o le cellulose tua.
2. Fa'atonuga mole:
Carbomer: Carbomers e iai se faʻalapotopotoga mole mole faʻatatau ona o lo latou natura fesoʻotaʻi. O lenei lala e fesoasoani i lo latou gafatia e fausia ai se fesoʻotaʻiga e tolu-dimensional pe a faʻamaʻaina, e taʻitaʻia ai le mafiafia lelei ma le gelling meatotino.
Hydroxyethylcellulose: O le hydroxyethylcellulose o lo'o taofiofia le fausaga laina ole cellulose, fa'atasi ai ma vaega hydroxyethyl o lo'o fa'apipi'i ile kulukose i luga ole filifili polymer. O lenei fausaga laina e a'afia ai lana amio o se mafiafia ma fa'amautu.
3. Solubility:
Carbomer: Carbomer e masani lava ona tuʻuina atu ile pauta ma e le mafai ona faʻafefe ile vai. Ae ui i lea, e mafai ona fulafula ma faʻafefe i vaifofo vai, faʻatupu ai gels manino poʻo faʻasalalau viscous.
Hydroxyethylcellulose: O le Hydroxyethylcellulose o lo'o tu'uina atu fo'i ile pauta ae e faigofie ona so'a ile vai. E fa'amavae e fai ai ni vaifofo manino pe laititi le pala, e fa'atatau i le fa'atonuga ma isi vaega fa'asusu.
4. Meatotino Mafiafia:
Carbomer: Carbomers o ni mea mafiafia sili ona lelei ma e mafai ona fatuina le viscosity i le tele o faʻatulagaga, e aofia ai kulimi, gels, ma lotions. Latou te tuʻuina atu mea lelei faʻamalolo ma e masani ona faʻaaogaina e faʻamautu ai emulsions.
Hydroxyethylcellulose: O le Hydroxyethylcellulose e galue foi e pei o se mafiafia ae faʻaalia ai se uiga eseʻese o le rheological faʻatusatusa i carbomers. E tu'uina atu se tafega fa'amamafa po'o le fa'amama fa'amama fa'asili i fau, o lona uiga e fa'aitiitia lona viscosity i lalo o le mamafa o le sile, fa'afaigofie ona fa'aoga ma sosolo.
5. Fesootaiga:
Carbomer: Carbomers e fetaui ma le tele o mea teuteu ma tulaga pH. Ae ui i lea, atonu latou te manaʻomia le faʻamavaeina ma le alkalis (faʻataʻitaʻiga, triethanolamine) e maua ai le sili ona lelei o le mafiafia ma le faʻafefe.
Hydroxyethylcellulose: Hydroxyethylcellulose e fetaui ma solvents eseese ma mea teuteu masani. E mautu i luga o le lautele o le pH ma e le manaʻomia le faʻagata mo le mafiafia.
6. Vaega o Fa'aoga:
Carbomer: E maua e Carbomers le tele o le faʻaogaina i mea tau tausiga a le tagata lava ia e pei o kulimi, lotion, gels, ma le tausiga o lauulu. O lo'o fa'aaogaina fo'i i mea tau vaila'au e pei o gels ma vaifofo ophthalmic.
Hydroxyethylcellulose: O le Hydroxyethylcellulose e masani ona fa'aaogaina i mea teuteu ma le tausiga o le tagata lava ia, e aofia ai shampoos, conditioners, fufulu tino, ma le toothpaste. E faʻaaogaina foʻi i vailaʻau faʻapitoa, aemaise lava i faʻasologa autu.
7. Uiga Fa'alogo:
Carbomer: O gels Carbomer e masani lava ona faʻaalia se mea lamolemole ma lubricious, tuʻuina atu se lagona manaʻomia i le faʻatulagaina. Ae ui i lea, atonu latou te lagona teisi teisi pe pipii pe a faʻaoga i nisi tulaga.
Hydroxyethylcellulose: O le Hydroxyethylcellulose e maua ai se lagona silika ma e le pipii i fua. O lana amio fa'amama fa'amama e fesoasoani i le fa'asalalauina ma le fa'amalieina faigofie, fa'aleleia ai le poto masani o tagata fa'aoga.
8. Manatu Fa'atonutonu:
Carbomer: Carbomers e masani ona aloaia o se saogalemu (GRAS) e pulega faʻatonutonu pe a faʻaaogaina e tusa ai ma faiga lelei gaosiga (GMP). Ae ui i lea, o mana'oga fa'atulafonoina fa'apitoa e mafai ona fesuisuia'i e fa'atatau i le fa'aogaina ma le fa'afanua fa'afanua.
Hydroxyethylcellulose: O le Hydroxyethylcellulose e manatu foi e saogalemu mo le faʻaaogaina i mea teuteu ma vailaʻau, faʻatasi ai ma faʻamaoniga faʻatonutonu mai pulega talafeagai. O le tausisia o tulafono ma taiala talafeagai e taua tele mo le mautinoa o le saogalemu ma le aoga o oloa.
E ui o le carbomer ma le hydroxyethylcellulose o loʻo avea ma mea faʻamalosi ma faʻamautu i faʻatulagaga eseese, e eseese i latou i tulaga o vailaʻau, fausaga mole, solubility, mea faʻafefeteina, fetaui, vaega faʻaoga, uiga faʻapitoa, ma iloiloga faʻatonutonu. O le malamalama i nei eseesega e taua tele mo tagata faʻapipiʻi e filifili ai le mea e sili ona talafeagai mo latou manaʻoga faʻapitoa ma tulaga faʻatinoga.
