Cysteamine (Cysteamine, CS), sidoo kale loo yaqaan β-merhydrylethylamine, budada crystalline cad, dhibic dhalaalaysa 99 ~ 100 ℃, wax yar udgoon, milmay biyaha iyo khamriga, falcelinta alkaline. Sababtoo ah waxay ka kooban tahay sulfhydryl firfircoon iyo kooxaha amino, waxay leedahay hawlo kala duwan oo bayooloji ah. Waa walax bayooloji ahaan firfircoon ku leh xayawaanka waxayna leedahay saameyn nafsiyeed oo muhiim ah. Unugyada Cysteamine ee thiol, hawada oksaydheynta fudud waxay noqotaa disulfide inta badan waxay isticmaashaa hydrochloride (CysteamineHydrochloride, CSH) beddelkeeda. Guryaha kiimikada CSH waa deggan yihiin, adag yihiin heerkulka qolka, hygroscopicity xooggan, oksaydhka fudud ee heerkulka sare, barta dhalaalka ee 70.2 ~ 70.7 ℃.

CS iyo hydrochloride-keeda (CSH) waa maaddooyin dhexdhexaad ah oo ka mid ah waxyaabaha la isku qurxiyo qaarkood, iyo sidoo kale wakiilka timaha yareeya perm-ka, waxaana loo isticmaali karaa soo saarista waxyaabaha kale ee la isku qurxiyo timaha.

Codsiga perms timaha, CSH guud ahaan waxaa lagu soo koobay CA (cysteamine hydrochloride).

Qiimaha logP wuxuu muujinayaa in cysteamine hydrochloride (CA) ay tahay lipophilic oo aad loo heli karo meesha borotiinnada hydrophobic ee timaha ku jira (octamer/microfibril).

Cysteamine hydrochloride (CA) sababtoo ah waxay ka kooban tahay sulfhydryl firfircoon, waxay jebisaa bond disulfide ee timaha, cystine waa la dhimay cysteine ??ka kooban sulfhydryl, timuhu waxay noqdaan kuwo jilicsan, foorarsan oo qallafsan curler timaha, ka dibna oxidized by wakiilka oxidizing si ay u jilicsan si loo gaaro saamayn curling wanaagsan. Faa'iido darrooyinkeedu waa inay u baahan tahay nadiif sare, waxay leedahay ur gaar ah, waxayna leedahay saameyn kicinta maqaarka. Sababtoo ah waa xanaaqa maqaarka, sharciga dawooyinka Japan ayaa qeexaya in CA ay ku jirto qeexitaan hoose oo hooseeya (inta badan waxaa lagu habeeyaa dhexdhexaad hoose oo dhexdhexaad ah oo dheeraad ah), sababtoo ah qaabeynta qeexitaanka gaarka ah, si culeyska timaha uu u hooseeyo, si timuhu u jilicsan yihiin oo caafimaad qabaan!

Saamaynta hoos u dhigista cysteamine hydrochloride (CA) way ka sarraysaa kan thioglycollic acid, sidaa darteed waxay muujinaysaa saamaynta curling ka wanaagsan ee hawlgalka curling. Marka la barbar dhigo isla PH-ga sare iyo xoogga sare ee thioglycollic acid, faa'iidada ugu weyn ee isticmaalka cysteamine hydrochloride (CA) timaha qalloocan waa in aan loo baahnayn in la kululeeyo wakhti dheer, iyo heerka curlka ee 5 daqiiqo oo leh qadar sare oo alkaline ah iyo dheecaan sare oo cysteamine hydrochloride perm waxay u dhigantaa saameynta isticmaalka thioglycollic acid.

Cysteamine hydrochloride waa xarun isku dhafan oo leh sifooyin kiimiko oo firfircoon waxayna samayn kartaa isku dhafan xasilloon, kaas oo door muhiim ah ka ciyaara shaqeynta timaha perms. Waxay leedahay qaab-dhismeedka filimka wanaagsan iyo dhaqdhaqaaqa kiimikaad sare leh, waxay samayn kartaa qaab-dhismeed xasilloon oo isku-dhafan oo leh keratin timaha, bedesho qaabka timaha, si loo gaaro saameynta perm.

Cysteamine hydrochloride perm ee geeddi-socodka perm, shaqadeeda ugu weyn waa in ay bixiso walax cusub oo iskutallaabta ah, iyo keratin ee timaha si ay u sameeyaan qaab-dhismeed xasilloon oo iskutallaab ah, beddel curlka timaha. Marka la barbar dhigo perms kale ee timaha, faa'iidada ay leedahay waa in ay leedahay dhaawac yar oo timaha, iyo saamaynta perm waa dabiici ah oo dheer.
