Cysteamine (Cysteamine, CS), ?ike pū ?ia ?o β-merhydrylethylamine, ka pauka crystalline ke?oke?o, wahi ho?ohehe?e 99 ~ 100 ℃, ?ala iki, ho?ohehe?e ?ia i ka wai a me ka wai?ona, ka hopena alkaline. No ka mea he sulfhydryl ikaika a me nā pū?ulu amino, loa?a iā ia nā ?ano hana biological. He mea ola kino ia i loko o nā holoholona a he hopena ko?iko?i ko?iko?i. Cysteamine mole o thiol, oluolu oxidation ea lilo disulfide ho?ohana pinepine i kona hydrochloride (CysteamineHydrochloride, CSH) ma ke ano he pani no ia. Pa?a nā waiwai kemika CSH, pa?a i ka mahana o ka lumi, hygroscopicity ikaika, ma?alahi ka ho?ohehe?e ?ana i nā wela ki?eki?e, ka helu hehe?e o 70.2 ~ 70.7 ℃.

?O CS a me kāna hydrochloride (CSH) nā mea ho?ohui i waena o kekahi mau mea ho?onaninani, a me kahi mea ho?oha?aha?a lauoho perm, a hiki ke ho?ohana ?ia i ka hana ?ana i nā mea ho?onaninani lauoho ?ē a?e.

I ka ho?ohana ?ana i nā perms lauoho, ua pōkole ?o CSH i CA (cysteamine hydrochloride).

Hō?ike ka waiwai logP he lipophilic ka cysteamine hydrochloride (CA) a hiki ke loa?a i kahi o nā protein hydrophobic i loko o ka lauoho (octamer/microfibril).

?O Cysteamine hydrochloride (CA) no ka mea aia ka sulfhydryl ikaika, wāwahi ia i ka pa?a disulfide i ka lauoho, ho?emi ?ia ka cystine i ka cysteine ??i loa?a ka sulfhydryl, lilo ka lauoho i palupalu, kūlou a deformed me ka curler lauoho, a laila oxidized e oxidizing agent i mea palupalu e ho?okō i kahi hopena curling maika?i a?e. ?O kona hemahema ?o ia ka mea e koi ai i ka ma?ema?e ki?eki?e, he ?ala kūikawā, a he hopena ho?oulu i ka ?ili. Ma muli o ka ho?onāukiuki?ana i ka?ili, ua'ōlelo ke kānāwai lapa?au Iapana i ka CA i loko o kahi kiko'ī ha?aha?a ha?aha?a (pinepine i ho?onohonoho?ia i loko o ka alkali ha?aha?a kū?oko?a), no kona ho?onohonoho kiko'ī kūikawā, i emi iho ka kaumaha o ka lauoho, i?oi aku ka palupalu a me ke olakino o ka lauoho!

?Oi aku ka ki?eki?e o ka hopena hō?emi o ka cysteamine hydrochloride (CA) ma mua o ka thioglycollic acid, no laila e hō?ike ana i ka hopena curling maika?i a?e i ka hana curling. Ke ho?ohālikelike ?ia me ka PH ki?eki?e a me ke ki?eki?e ki?eki?e o ka waika thioglycollic, ?o ka pōmaika?i nui loa o ka ho?ohana ?ana i ka lauoho lauoho cysteamine hydrochloride (CA) ?a?ole pono ia e wela no ka manawa lō?ihi, a ?o ke ki?eki?e curl o 5 mau minuke me kahi ki?eki?e alkaline a ki?eki?e ki?eki?e cysteamine hydrochloride perm e like me ka hopena o ka ho?ohana ?ana i ka thioglycollic acid no 15 mau minuke.

?O ka Cysteamine hydrochloride kahi pūhui versatile me nā waiwai kemika ikaika a hiki ke hana i kahi pa?a pa?a, kahi mea nui i ka hana o nā perms lauoho. Loa?a iā ia ka hana ki?i?oni?oni maika?i a me ka hana kemika ki?eki?e, hiki ke hana i kahi ?ano pa?a pa?a me ka keratin o ka lauoho, ho?ololi i ke ?ano o ka lauoho, i mea e ho?okō ai i ka hopena o ka perm.

?O Cysteamine hydrochloride perm i ke ka?ina hana o ka perm, kāna hana nui e hā?awi i kahi mea crosslinking hou, a me ka keratin o ka lauoho e hana i kahi ?ano crosslinking pa?a, ho?ololi i ka curl o ka lauoho. Ke ho?ohālikelike ?ia me nā perms lauoho ?ē a?e, ?o kona pōmaika?i ?o ia ka li?ili?i o ka pō?ino i ka lauoho, a ?o ka hopena o ka perm he kūlohelohe a lō?ihi.
