Cysteamine (Cysteamine,CS), ekwaziwa ngokuba yi-β-merhydrylethylamine, i-white crystalline powder, i-melting point 99 ~ 100℃, ivumba elincinci, i-soluble emanzini kunye notywala, ukusabela kwe-alkaline. Ngenxa yokuba iqulethe i-sulfhydryl esebenzayo kunye namaqela e-amino, inemisebenzi eyahlukeneyo yebhayoloji. Yinto esebenzayo kwizilwanyana kwaye ineziphumo ezibalulekileyo zomzimba. Iimolekyuli ze-Cysteamine ze-thiol, i-oxidation air elula iba yi-disulfide isoloko isebenzisa i-hydrochloride yayo (i-CysteamineHydrochloride, i-CSH) njengendawo yayo. Iimpawu zeekhemikhali ze-CSH zizinzile, ziqinile kwiqondo lokushisa, i-hygroscopicity eqinile, i-oxidation elula kumaqondo obushushu aphezulu, indawo yokunyibilika ye-70.2 ~ 70.7 ℃.

I-CS kunye ne-hydrochloride yayo (i-CSH) zizithako eziphakathi kwezinye izinto zokuthambisa, kunye ne-agent yokunciphisa iinwele, kwaye inokusetyenziswa ekwenzeni ezinye izithambiso zokuthambisa iinwele.

Ekusetyenzisweni kweeperms zeenwele, i-CSH iyancipha ngokubanzi kwi-CA (cysteamine hydrochloride).

Ixabiso le-logP libonisa ukuba i-cysteamine hydrochloride (CA) i-lipophilic kwaye ifikeleleke ngakumbi kwindawo yeeprotheni ze-hydrophobic ngaphakathi kweenwele (i-octamer / microfibril).

I-Cysteamine hydrochloride (CA) ngenxa yokuba iqulethe i-sulfhydryl esebenzayo, iqhawula i-disulfide bond ezinweleni, i-cystine iyancitshiswa ibe yi-cysteine ????equlethe i-sulfhydryl, iinwele ziba thambileyo, zigobe kwaye zikhubazeke nge-curler yeenwele, kwaye emva koko zifakwe i-oxidizing agent ukuze ziyenze ibe thambileyo ukufezekisa umphumo ongcono wokugoba. Ukungalungi kwayo kukuba ifuna ukucoceka okuphezulu, inephunga elikhethekileyo, kwaye inefuthe elikhuthazayo kwesikhumba. Ngenxa yokuba iyacaphukisa ulusu, umthetho waseJapan wamayeza uchaza ukuba i-CA ikwindawo ephantsi yoxinaniso (ehlala iqwalaselwe kwi-alkali ephantsi engathathi hlangothi ngaphezulu), ngenxa yokucwangciswa kwayo okukhethekileyo, ukuze umthwalo weenwele ube ngaphantsi, ukuze iinwele zithambile kwaye zisempilweni!

Isiphumo sokunciphisa i-cysteamine hydrochloride (CA) iphezulu kune-thioglycollic acid, ngoko ibonisa umphumo ongcono wokugoba ekusebenzeni kwe-curling. Xa kuthelekiswa ne-PH efanayo ephezulu kunye noxinzelelo oluphezulu lwe-thioglycollic acid, inzuzo enkulu yokusebenzisa i-cysteamine hydrochloride (CA) iinwele ezigobileyo kukuba ayifuni ukufudumeza ixesha elide, kwaye i-curl degree yemizuzu emi-5 kunye ne-alkaline ephezulu kunye ne-concentration ephezulu ye-cysteamine hydrochloride perm ilingana nomphumo wokusebenzisa i-thioglycol imizuzu ye-thio1.

I-Cysteamine hydrochloride i-compound eguquguqukayo kunye neempawu zeekhemikhali ezisebenzayo kwaye inokwenza i-complex ezinzile, edlala indima ephambili ekusebenzeni kweeperms zeenwele. Inokwakheka kwefilimu efanelekileyo kunye nomsebenzi ophezulu weekhemikhali, unokwenza isakhiwo esizinzile se-cross-link kunye ne-keratin yeenwele, utshintshe isakhiwo seenwele, ukuze ufezekise umphumo we-perm.

I-Cysteamine hydrochloride perm kwinkqubo ye-perm, umsebenzi wayo oyintloko kukubonelela nge-agent entsha ye-crosslinking, kunye ne-keratin yeenwele ukuba zenze isakhiwo esinqamlekileyo esizinzile, sitshintshe i-curl yeenwele. Xa kuthelekiswa nezinye iiperms zeenwele, inzuzo yayo kukuba inomonakalo omncinci kwizinwele, kwaye umphumo we-perm ungokwemvelo kwaye uhlala ixesha elide.
