1. Isishwankathelo se-hydroxypropyl methylcellulose
IHydroxypropyl methylcellulose (HPMC)yi-ether ye-cellulose engeyo-ionic eyenziwe kwi-cellulose yezityalo zendalo ngokuguqulwa kweekhemikhali, kunye nokunyibilika kakuhle kwamanzi kunye nokuhambelana kwezinto eziphilayo. Isetyenziswe ngokubanzi kumashishini okutya, amayeza, ukwakhiwa kunye nemihla ngemihla, ngakumbi kwiimveliso zokunakekelwa kwesikhumba. I-HPMC iye yaba yinto yokongeza esebenzayo ngenxa yeempawu zayo ezizodwa zomzimba kunye neekhemikhali, ezinokuphucula ukuthungwa kwemveliso, ukuzinza kunye namava omsebenzisi.
2. Indima ephambili ye-hydroxypropyl methylcellulose kwiimveliso zokunakekelwa kwesikhumba
2.1 Isilungisi se-Thickener kunye ne-rheology
I-HPMC inekhono elihle lokutyeba kwaye inokwenza ijeli ecacileyo okanye eguquguqukayo kwisisombululo esinamanzi, ukuze iimveliso zokunakekelwa kwesikhumba zibe ne-viscosity efanelekileyo kunye nokuphucula ukusasazeka kunye nokunamathela kwemveliso. Umzekelo, ukongeza i-HPMC kwizinto zokuthambisa, iikhrimu, izinto ezisisiseko, kunye neemveliso zokucoca zinokuhlengahlengisa ukuhambelana kwaye zithintele imveliso ekubeni ibhityile kakhulu okanye ityebe kakhulu ukuba ingasasazwa. Ukongeza, HPMC nako ukuphucula iimpawu rheological yefomula, ukwenza imveliso lula extrude kwaye isasazeke ngokulinganayo, ezisa ukuvakalelwa ngcono ulusu.
2.2 I-Emulsion stabilizer
Kwiimveliso zokunakekelwa kwesikhumba eziqulethe inkqubo ye-oyile yamanzi efana ne-lotion kunye ne-cream, i-HPMC ingasetyenziselwa njenge-emulsion stabilizer yokunceda isigaba seoli kunye nesigaba samanzi sidibanise kakuhle kwaye sithintele i-stratification yemveliso okanye i-demulsification. Inokuphucula ukuzinza kwe-emulsion, iphucule ukufana kwe-emulsion, yenza ukuba kungabi lula ukuwohloka ngexesha lokugcinwa, kunye nokwandisa ubomi beshelufu yemveliso.
2.3 Ifilimu yangaphambili
I-HPMC inokwenza ifilimu ekhuselayo ephefumlayo nethambileyo kumphezulu wolusu, inciphise ilahleko yamanzi, kwaye iphucule isiphumo sokuthambisa ulusu. Olu phawu luyenza ibe sisithako esiqhelekileyo sokuthambisa kwiimveliso zokhathalelo lwesikhumba, kwaye isetyenziswa kwiimveliso ezinjengeemaski zobuso, izitshizi zokuthambisa, kunye nezithambiso zezandla. Emva kokwenziwa kwefilimu, i-HPMC inokuphucula ukuthamba kunye nokuguda kolusu kunye nokuphucula ukumila kolusu.
2.4 Isixhobo sokuthambisa
I-HPMC inesakhono esinamandla se-hygroscopic, inokufunxa ukufuma emoyeni kwaye itshixe ukufuma, kwaye ibonelele ngefuthe lexesha elide lokuthambisa ulusu. Ilungele ngokukhethekileyo iimveliso zokunakekelwa kwesikhumba ezomileyo, ezifana ne-lotions eyomileyo, i-creams kunye ne-eye creams, enokunceda ulusu lugcine isimo se-hydrated. Ukongeza, inokunciphisa ukoma kwesikhumba okubangelwa kukuphuma kwamanzi, okwenza ukuba isiphumo sokhathalelo lwesikhumba sihlale.
2.5 Uzinzo olongeziweyo
I-HPMC inokuphucula uzinzo lwezithako ezisebenzayo kwiimveliso zokunakekelwa kwesikhumba kunye nokunciphisa ukuthotywa okubangelwa ubushushu, ukukhanya okanye utshintsho lwe-pH. Ngokomzekelo, kwiimveliso eziqulethe i-vitamin C, i-asidi yeziqhamo, i-extracts yezityalo, njl njl ezithintekayo kwizinto ezisingqongileyo, i-HPMC inokunciphisa ukuthotywa kwezithako kunye nokuphucula ukusebenza kwemveliso.
2.6 Nika ulusu olusilika
Ukunyibilika kwamanzi kwe-HPMC kunye neempawu ezithambileyo zokwenza ifilim ziyenza ikwazi ukwenza ukubamba okugudileyo nokuhlaziyayo kumphezulu wolusu ngaphandle kwemvakalelo encangathi. Le propati yenza ukuba ibe yinto ebalulekileyo yokongeza kwiimveliso zokunakekelwa kwesikhumba eziphezulu, ezinokuthi ziphucule amava esicelo kwaye zenze ulusu lube lula kwaye lube lukhuni.
2.7 Ukuhambelana nokukhuselwa kwendalo
I-HPMC i-polymer engeyiyo i-ionic kunye nokuhambelana kakuhle kunye nezithako ezininzi zokunakekelwa kwesikhumba (ezifana ne-surfactants, i-moisturizers, i-extracts yezityalo, njl.) kwaye akukho lula ukukhawuleza okanye ukuhlutha. Kwangaxeshanye, i-HPMC ithathwe kwimicu yezityalo zendalo, inokonakala kwezinto eziphilayo, kwaye inobuhlobo nokusingqongileyo, ngoko ke ikwasetyenziswa ngokubanzi kwiimveliso zokhathalelo lwesikhumba eziluhlaza kunye nokusingqongileyo.
3. Imizekelo yokusetyenziswa kwiimveliso ezahlukeneyo zokunakekelwa kwesikhumba
Abahlambululi bobuso (abahlambululi, abacoci be-foam): I-HPMC inokuphucula ukuzinza kwe-foam kwaye iyenze i-denser. Kwakhona yenza ifilimu encinci ebusweni besikhumba ukunciphisa ukulahlekelwa kwamanzi ngexesha lokucoca.
Iimveliso zokhathalelo lwesikhumba (i-lotions, i-creams, i-essces): Njenge-thickener, ifilimu yangaphambili kunye ne-moisturizer, i-HPMC inokunyusa i-viscosity yemveliso, iphucule umphumo wokufuma, kwaye izise i-silky touch.
I-sunscreen: I-HPMC inceda ukuphucula ukuhanjiswa okufanayo kwezithako ze-sunscreen, ukwenza i-sunscreen ibe lula ukuyisebenzisa ngelixa inciphisa imvakalelo enamafutha.
Iimaski zobuso (iimaski zeshiti, iimaski ze-smear): I-HPMC inokuphucula i-adsorption yelaphu lemaski, ivumela undoqo ukuba ugqume ngcono ulusu kwaye uphucule ukungena kwezithako zokhathalelo lwesikhumba.
Iimveliso ze-Makeup (isiseko solwelo, i-mascara): Kwisiseko solwelo, i-HPMC inokubonelela nge-ductility egudileyo kunye nokuphucula ukufaneleka; kwi-mascara, inokuphucula ukunamathela kwi-paste kwaye yenza i-eyelashes ibe nzima kwaye igobe.
4. Ukhuseleko kunye nezilumkiso zokusetyenziswa
Njengesongezo sokuthambisa, i-HPMC ikhuselekile ngokwentelekiso, iphantsi ngokucaphuka kunye nokungagugi, kwaye ilungele uninzi lweentlobo zesikhumba, kubandakanya ulusu olubuthathaka. Nangona kunjalo, xa uyila ifomula, kuyimfuneko ukulawula ubungakanani obufanelekileyo bokudibanisa. Uxinzelelo oluphezulu kakhulu lunokwenza imveliso ibonakale kakhulu kwaye ichaphazele ulusu luziva. Ukongezelela, kufuneka kugwenywe ukuxuba kunye ne-asidi ethile eqinile okanye izithako ezinamandla ze-alkaline ukuphepha ukuchaphazela ukuqina kwayo kunye neempawu zokwenza ifilimu.
IHydroxypropyl methylcelluloseinoluhlu olubanzi lwexabiso lesicelo kwiimveliso zokunakekelwa kwesikhumba. Ingasetyenziswa njenge-thickener, i-emulsifier stabilizer, ifilimu yangaphambili kunye ne-moisturizer ukuphucula ukuzinza, ukuvakalelwa kunye nefuthe lokunakekelwa kwesikhumba kwimveliso. I-biocompatibility yayo elungileyo kunye neepropathi zokhuseleko lokusingqongileyo ziyenza ibe sisithako esiyimfuneko kwiifomula zokhathalelo lwangoku lwesikhumba. Ngokunyuka kwengcamango yokunakekelwa kwesikhumba eluhlaza kunye nokusingqongileyo, amathuba okusetyenziswa kwe-HPMC aya kuba abanzi, ukubonelela abathengi ngamava angcono okunakekelwa kwesikhumba.
