Kwimveliso yanamhlanje kunye nemveliso yemihla ngemihla, izithako ezininzi zekhemikhali ezikhuselekileyo nezithambileyo zixhasa umgangatho ozinzileyo kunye namava okusetyenziswa kakuhle kweempahla ezahlukeneyo.I-PEG-50 (CAS 61788-85-0), i-polyethylene glycol derivative eqhelekileyo, ifumene udumo olubanzi kwiindawo ezininzi ngenxa yeempawu zayo ezizinzileyo zeekhemikhali, ubume obuthambileyo kunye neempawu ezahlukeneyo zokusebenza. Ngokungafaniyo nezinye izixhobo zoshishino zobungcali ezisetyenziswa kanye, esi sithako sinokuziqhelanisa neemfuno ezahlukeneyo zemveliso, sigubungela ukhathalelo lomntu, imveliso yamayeza, ukucubungula amalaphu kunye nokuveliswa kweekhemikhali zemihla ngemihla. Ngokusebenza okulula nokuthembekileyo, ibe yinto esisiseko yokuncedisa kwiifomyula ezininzi zemveliso eziphambili.

Ukusetyenziswa okuqhelekileyo kwe-PEG-50 kuxhomekeke kushishino lokhathalelo lomntu kunye nokuhombisa, oluhambelana kakhulu nobomi bemihla ngemihla babantu. Uninzi lweemveliso zokhathalelo lolusu kunye nobuhle zifuna iifomyula ezilungelelanisiweyo zokuxuba izinto ezisetyenzisiweyo kwioyile kunye nezisekelwe emanzini ngokulinganayo, kwaye i-PEG-50 idlala indima ebalulekileyo kule nkqubo. Isebenza njenge-emulsifier kunye ne-solubilizer esebenzayo, inceda ukudibanisa izithako ezahlukeneyo ezingenakuxubana ngokwendalo. Kwiikhrimu zobuso, iiloshini kunye neemveliso zokhathalelo lwelanga, igcina ubume bemveliso bufana kwaye buthambile, ithintela ukwahlukana komaleko okanye imvula ngexesha lokugcina nokusetyenziswa.

Ngaphandle kwemiphumo yokuxuba, i-PEG-50 ikwanayo nemisebenzi emihle yokufumisa nokulungisa iinwele. Ingenza ifilimu encinci yokukhusela phezu kolusu neenwele zomntu, ivale umswakama ngaphakathi, kwaye inciphise ukoma kunye noburhabaxa. Kwiimveliso zokhathalelo lolusu ezijolise kulusu olomileyo, esi sithako sinceda ukuphucula ubume bolusu kwaye sigcine ulusu luthambile ixesha elide ngaphandle kokuzisa iimvakalelo eziqinileyo okanye ezinamafutha. Kwiimveliso zokhathalelo lweenwele ezifana nezilungisi zeenwele kunye ne-styling lotions, igudisa imicu yeenwele ezirhabaxa, inciphisa ukurhawuzelela kweenwele okubangelwa kukoma, kwaye yenza iinwele zibe lula ukuzikama nokuzibumba. Ikwafakwa kwiitoni zobuso kunye neemveliso ze-aftershave ukuze kuthomalaliswe ulusu kwaye kugcinwe ulungelelwaniso olusisiseko lokufuma kolusu.

Ukongeza kwiinkalo zobuhle kunye nokhathalelo lolusu,I-PEG-50Isetyenziswa kakhulu kwiimveliso zokucoca zemihla ngemihla. Izicoci zezandla, isepha yezandla elulwelo kunye nezisombululo zokucoca ezithambileyo zihlala ziqulathe esi sithako. Ingenza ngcono ukuqina kweemveliso zokucoca, yenze ubume bemveliso bube bukhulu ngakumbi, kwaye iphucule indlela esetyenziswa ngayo. Okwangoku, inceda ekunyibilikiseni izinto zokucoca ezisebenzayo kunye nezithako zevumba, yenza isiphumo sokucoca silingane ngakumbi kwaye ivumba lihlale ixesha elide. Uhlobo lwayo oluthambileyo lweekhemikhali luqinisekisa ukuba aluyi kubangela ukurhawuzelelwa okukhulu kulusu lomntu, ngoko ke ifanelekile kwimveliso yezinto zokucoca ezithambileyo zemihla ngemihla zokusetyenziswa rhoqo imihla ngemihla.

Ishishini lamayeza lelinye imeko ebalulekileyo yokusetyenziswa kwe-PEG-50, apho ukhuseleko kunye nozinzo lwayo luxatyiswa ngokupheleleyo. Kwimveliso yamayeza angaphandle angaphandle, isebenza njengesixhobo esizinzileyo kunye nesinyibilikisi. Inganyibilikisa ngokupheleleyo izithako ezisebenzayo zonyango, incede ezi zithako zinamathele kumphezulu wolusu kwaye isebenzise kancinci imiphumo yazo, iphucula izinga lokusetyenziswa kwezithako zonyango. Ngaphezu koko, iimpawu zayo ezithambileyo zinciphisa umngcipheko wokurhawuzelelwa lusu okubangelwa ngamayeza angaphandle, anobuhlobo kumaqela esikhumba anobuthathaka. Kwezinye izixhobo ezincedisayo zokulungiselela iikhaphu kunye nezomlomo, i-PEG-50 ikwasebenza njengesisasazi kunye nesiqinisi sokugcina izinto zangaphakathi zamayeza zifana kwaye iqinisekise umgangatho weziyobisi ozinzileyo ngexesha lokuphelelwa.

Ishishini leempahla zelaphu likwaxhomekeke kwimisebenzi esebenzayo ye-PEG-50 ekuveliseni nasekucubunguleni. Kwinkqubo yokusonta iifayibha zamakhemikhali kunye nokuluka amalaphu, esi sithako singasetyenziswa njengesithambisi kunye nesithambisi. Sinciphisa ukungqubana phakathi kweentambo zefayibha, sinciphisa amathuba okuqhekeka kwentambo ngexesha lokucubungula ngoomatshini, kwaye siphucula ukusebenza kakuhle kwemveliso. Emva kokucubungula nge-PEG-50, amalaphu elaphu aya kuba nemvakalelo ethambileyo negudileyo yesandla, kwaye intuthuzelo yokunxiba yeempahla ezigqityiweyo iyaphucuka. Ukongeza, ineziphumo ezithile zokulwa nokungaguquguquki, ezinokunciphisa umbane ongaguqukiyo oveliswa kukungqubana ngexesha lokusetyenziswa kwelaphu, okwenza ukunxitywa kwemihla ngemihla kunye nokusetyenziswa kwamalaphu kube lula ngakumbi.

Kwimimandla yokuvelisa imveliso yemizi-mveliso, i-PEG-50 ikwanokusetyenziswa okuzinzileyo nokusebenzisekayo. Ingasetyenziswa njenge-emulsifier encedisayo kwi-emulsification yeparafini kunye nemveliso yezithambiso, inceda izinto ezahlukeneyo zokwenza imveliso yemizi-mveliso ukuba zenze iinkqubo ezidibeneyo ezizinzileyo. Kwinkqubo yokucubungula isinyithi kunye neenkqubo zokugquma zemizi-mveliso zemihla ngemihla, isebenza njengesisasazi kunye nesithambiso, inciphisa ukuguguleka kwezixhobo kwaye iphucula isiphumo sokucubungula imiphezulu yemveliso. Ukunyibilika kwayo kakuhle kwamanzi kwenza kube lula ukuyicoca nokuyiphatha kwimveliso yemizi-mveliso, ehambelana neemfuno zokusebenza ezisisiseko zemveliso yemizi-mveliso yanamhlanje.

Enye yezona zinto ziphambiliiingenelo zeoyile ye-castor e-hydrogenated hydrogenatedIlele ekuhambelaneni kwayo okuphezulu kunye nokungacaphuki kakuhle. Inokuhlala kakuhle nezinye izinto ezisetyenziswa kakhulu kwimveliso yemihla ngemihla, kwaye ayizukuvelisa iziphumo ezinobungozi zeekhemikhali okanye ichaphazele ukusebenza okuphambili kweemveliso. Emva kokuqinisekiswa okusebenzayo ixesha elide kumashishini ahlukeneyo, ibonisa ukhuseleko oluhle ekunxibelelaneni nasekusetyenzisweni kwemihla ngemihla, nto leyo esona sizathu siphambili sokuba ingasetyenziswa kakhulu kwiimveliso ezisondelelene nemizimba yabantu. Iimpawu zayo zomzimba nezekhemikhali eziphakathi ziyenza ikwazi ukuziqhelanisa neendawo ezahlukeneyo zemveliso kunye neenkqubo zefomula, nto leyo ezisa indawo eguquguqukayo yesicelo sophando nophuhliso lwemveliso.

Ngokuphuculwa okuqhubekayo kweukwenziwa kwemveliso yemihla ngemihlakunye nemigangatho yemveliso yemizi-mveliso, imfuno yemarike yezithako ezincedisayo ezikhuselekileyo, ezithambileyo nezinemisebenzi emininzi iyaqhubeka nokunyuka. I-PEG-50, enobuchule bayo bokusetyenziswa kwiindawo ezininzi kunye nokusebenza okuzinzileyo okubanzi, igcina ixabiso lokusetyenziswa elizinzileyo kwiindawo ezininzi. Ayinazo izithintelo zokusetyenziswa ezintsonkothileyo kwaye inokuhlangabezana neemfuno zefomyula ezisisiseko zeemveliso zemihla ngemihla kunye nemveliso encedisayo yemizi-mveliso. Kwixesha elizayo, ngokuphuculwa okuqhubekayo kweenkqubo zemveliso, esi sithako sisisiseko esisebenzayo siya kusetyenziswa ngakumbi kwiindawo ezikhulayo, siqhubeka nokubonelela ngenkxaso ethembekileyo yokuphucula umgangatho weemveliso zemihla ngemihla kunye nemveliso yemizi-mveliso.
