Cysteamine (Cysteamine, CS), yomwe imadziwikanso kuti β-merhydrylethylamine, ufa wa crystalline woyera, malo osungunuka 99 ~ 100 ℃, onunkhira pang'ono, osungunuka m'madzi ndi mowa, alkaline reaction. Chifukwa imakhala ndi magulu a sulfhydryl ndi amino, imakhala ndi ntchito zosiyanasiyana zamoyo. Ndi biologically yogwira mankhwala nyama ndipo ali ndi zofunika zokhudza thupi. Mamolekyu a Cysteamine a thiol, mpweya wotsekemera wosavuta amakhala disulfide nthawi zambiri amagwiritsa ntchito hydrochloride yake (CysteamineHydrochloride, CSH) m'malo mwake. CSH mankhwala katundu ndi okhazikika, olimba kutentha firiji, wamphamvu hygroscopicity, makutidwe ndi okosijeni mosavuta pa kutentha kwambiri, kusungunuka mfundo 70.2 ~ 70.7 ℃.

CS ndi hydrochloride yake (CSH) ndi zosakaniza zapakatikati mu zodzoladzola zina, komanso zochepetsera tsitsi, ndipo zitha kugwiritsidwa ntchito popanga zodzoladzola zina zopaka tsitsi.

Pogwiritsa ntchito zilolezo za tsitsi, CSH nthawi zambiri imafupikitsidwa kukhala CA (cysteamine hydrochloride).

Mtengo wa logP umasonyeza kuti cysteamine hydrochloride (CA) ndi lipophilic ndipo imapezeka mosavuta kumalo a mapuloteni a hydrophobic mkati mwa tsitsi (octamer/microfibril).

Cysteamine hydrochloride (CA) chifukwa imakhala ndi sulfhydryl yogwira, imaphwanya chomangira cha disulfide mu tsitsi, cystine imachepetsedwa kukhala cysteine ????ili ndi sulfhydryl, tsitsi limakhala lofewa, lopindika komanso lopunduka ndi chowongolera tsitsi, kenako limapangidwa ndi oxidizing wothandizira kuti likhale lofewa kuti likwaniritse bwino kupindika. Choyipa chake ndi chakuti chimafuna chiyero chapamwamba, chimakhala ndi fungo lapadera, ndipo chimakhala ndi zotsatira zolimbikitsa pakhungu. Chifukwa zimakwiyitsa khungu, lamulo la ku Japan la mankhwala linanena kuti CA ili mu ndondomeko yochepetsetsa (nthawi zambiri imapangidwira mu alkali yochepa kwambiri), chifukwa cha kukhazikitsidwa kwake kwapadera, kuti tsitsi likhale lochepa, kotero kuti tsitsi likhale lofewa komanso lathanzi!

Zotsatira zochepetsera za cysteamine hydrochloride (CA) ndizokwera kuposa za thioglycollic acid, chifukwa chake zimawonetsa bwino kupiringa pogwira ntchito yopiringa. Poyerekeza ndi PH yemweyo komanso kuchuluka kwa thioglycollic acid, mwayi waukulu wogwiritsa ntchito tsitsi lopindika la cysteamine hydrochloride (CA) ndikuti silifunika kutenthedwa kwa nthawi yayitali, ndipo digirii yopindika ya mphindi 5 yokhala ndi zamchere kwambiri komanso ndende yayikulu ya cysteamine hydrochloride perm ndi yofanana ndi zotsatira za kugwiritsa ntchito thio15 acid ya thio15 acid.

Cysteamine hydrochloride ndi gulu losunthika lomwe limakhala ndi zinthu zogwira ntchito ndipo limatha kupanga chokhazikika chokhazikika, chomwe chimagwira ntchito yofunika kwambiri pakugwira ntchito kwa ma perms atsitsi. Ili ndi mapangidwe abwino a filimu komanso ntchito zambiri zamakina, zimatha kupanga mawonekedwe okhazikika olumikizana ndi keratin wa tsitsi, kusintha mawonekedwe a tsitsi, kuti akwaniritse zotsatira za perm.

Cysteamine hydrochloride perm mu ndondomeko ya perm, ntchito yake yaikulu ndi kupereka latsopano crosslinking wothandizira, ndi keratin wa tsitsi kupanga khola crosslinking dongosolo, kusintha lopiringizika tsitsi. Poyerekeza ndi zilolezo zina za tsitsi, ubwino wake ndi wakuti alibe kuwonongeka pang'ono kwa tsitsi, ndipo zotsatira za perm ndi zachilengedwe komanso zokhalitsa.
