Cysteamine (Cysteamine, CS), inozivikanwawo se β-merhydrylethylamine, white crystalline powder, melting point 99 ~ 100 ℃, inonhuwa zvishoma, inonyungudika mumvura uye doro, alkaline reaction. Nekuti ine inoshanda sulfhydryl uye amino mapoka, ine akasiyana ezvipenyu mabasa. Iro biologically inoshanda mumhuka uye ine zvakakosha physiological effects. Cysteamine mamorekuru ethiol, nyore oxidation mhepo inova disulfide inowanzoshandisa yayo hydrochloride (CysteamineHydrochloride, CSH) sechinzvimbo chayo. CSH kemikari zvivakwa zvakatsiga, yakasimba pakamuri tembiricha, yakasimba hygroscopicity, nyore oxidation pakupisa kwakanyanya, kunyungudika kwe70.2 ~ 70.7 ℃.

CS uye hydrochloride yayo (CSH) zvinhu zvepakati mune zvimwe zvekuzora, pamwe chete nebvudzi perm reducing agent, uye zvinogona kushandiswa mukugadzira zvimwe zvizorwa zvebvudzi.

Mukushandiswa kwebvudzi remvumo, CSH inowanzopfupikiswa kuCA (cysteamine hydrochloride).

Iyo logP kukosha inoratidza kuti cysteamine hydrochloride (CA) i lipophilic uye inosvikika kune nzvimbo ye hydrophobic mapuroteni mukati mebvudzi (octamer/microfibril).

Cysteamine hydrochloride (CA) nekuti ine inoshanda sulfhydryl, inotyora disulfide bond mubvudzi, cystine inoderedzwa kuita cysteine ??ine sulfhydryl, vhudzi rinova rakapfava, rakakotama uye rakaremara nebvudzi curler, uyezve oxidized neoxidizing agent kuti riite nyoro kuti riite zvirinani kupeta. Kukanganisa kwayo ndeyekuti inoda kuchena kwepamusoro, ine kunhuhwirira kwakakosha, uye ine simba rinokurudzira paganda. Nemhaka yokuti inogumbura ganda, mutemo weJapan wemishonga unotaura kuti CA iri muhuwandu hwekugadzirisa hutsika (kazhinji inogadziriswa mune imwe nzvimbo yakaderera alkali yakawanda), nekuda kwekugadziriswa kwayo kwakakosha, kuitira kuti mutoro webvudzi udzike, kuitira kuti bvudzi rive rakapfava uye rine hutano!

Iyo yekudzikisa mhedzisiro ye cysteamine hydrochloride (CA) yakakwira kupfuura iyo ye thioglycollic acid, saka inoratidza zvirinani curling mukushanda kwe curling. Kuenzaniswa neiyo yakafanana yakakwirira PH uye yakakwira thioglycollic acid, mukana mukuru wekushandisa cysteamine hydrochloride (CA) bvudzi rakamonana nderekuti haridi kupiswa kwenguva yakareba, uye iyo curl degree ye5 maminetsi ane alkaline yakanyanya uye yakakwirira concentration cysteamine hydrochloride perm yakaenzana nemhedzisiro yekushandisa thioglycol maminitsi makumi mashanu neshanu.

Cysteamine hydrochloride isanganiswa inosiyana-siyana ine inoshanda makemikari zvinhu uye inogona kuumba yakagadzikana yakaoma, iyo inoita basa rakakosha mukushanda kwebvudzi perms. Iyo ine yakanaka yekugadzira firimu uye yakakwira makemikari chiitiko, inogona kugadzira yakagadzikana yakachinjika-yakabatana chimiro nekeratin yebvudzi, shandura chimiro chebvudzi, kuitira kuti uwane mhedzisiro yeperm.

Cysteamine hydrochloride perm in the process of perm, basa rayo guru nderokupa mutsva wekuyambuka, uye keratin yebvudzi kuti iite yakanyatsogadzikana crosslinking chimiro, shandura curl yebvudzi. Kuenzaniswa nemamwe mabvudzi ebvudzi, zvakanakira kuti hazvina kukuvadza zvishoma kune bvudzi, uye mhedzisiro yeperm ndeyechisikigo uye inogara kwenguva refu.
