●Kodi Ndi Chiyani Zinc pyrithione?
Zinc pyrithione (ZPT) ndi organic zinc complex ndi molecular formula ya C₁₀H₈N₂O₂S₂Zn (mamolekyu olemera 317.7). Dzina lake limachokera ku zosakaniza zachilengedwe za chomera cha Annonaceae Polyalthia nemoralis, koma makampani amakono atengera kaphatikizidwe ka mankhwala kuti apange. Mu 2024, njira yovomerezeka yaku China idadumphira m'botolo loyera, ndipo zonyansa za crotonic acid zidawongoleredwa pansi pa 16ppm kudzera pa methanol-acetone graded crystallization, ndipo chiyero chamankhwala chidakwera mpaka 99.5%.
Thupi ndi mankhwala katundu:
Maonekedwe ndi solubility: woyera kwa pang'ono yellow crystalline ufa, pafupifupi insoluble m'madzi (<0.1g/100mL), pang'ono sungunuka Mowa, solubility mu polyethylene glycol akhoza kufika 2000mg/kg;
Zofooka zokhazikika: tcheru ku kuwala ndi okosijeni, mosavuta kuwonongeka ndi kuwala kwa ultraviolet, ma CD a bulauni amafunikira; kulephera kwa dissociation pa pH <4.5 kapena> 9.5, pH yoyenera ndi 4.5-9.5;
Kutentha kwa kutentha kwapakati: kukhazikika kwa maola 120 pa 100 ℃, koma kuwola mofulumira pamwamba pa 240 ℃;
Kusagwirizana: kumayambitsa ma cationic surfactants, chelates ndi discolors ndi ayoni achitsulo / amkuwa (ngakhale 1ppm angapangitse kuti mankhwalawo akhale achikasu).
●Ndi ChiyaniUbwinoZa Zinc pyrithione ?
ZPT imakwaniritsa njira yoletsa kubereka (yogwira ntchito motsutsana ndi mitundu 32 ya tizilombo toyambitsa matenda) kudzera mu njira yapadera yosinthira ma ion, makamaka Malassezia, woyambitsa dandruff, wokhala ndi MIC yotsika mpaka 8ppm:
1. Kuwonongeka kwa Ion Gradient
M'malo a acidic, H⁺ imalowetsedwa mu mabakiteriya ndipo K⁺ imatuluka, ndipo m'malo amchere, Na⁺/Mg²⁺ imalowetsedwa m'malo, zomwe zimasokoneza njira yoyendera michere ya tizilombo tating'onoting'ono;
2. Kuwonongeka kwa Ma cell Membrane
Kulowetsa mu phospholipid bilayer, kukulitsa kutulutsa kwa membrane ndikuyambitsa kutayikira kwazinthu zamkati;
3. Kuletsa Ntchito ya Enzyme
Kuletsa mayendedwe a ma elekitironi ndikuletsa ma enzymes ofunikira a metabolism yamphamvu (monga ATP synthase).
Kutsimikizira kwachipatala: Mukamagwiritsa ntchito shampu yokhala ndi 1.5%zincpyrithionekwa masabata 4, dandruff imachepetsedwa ndi 90%, ndipo kuchuluka kwa seborrheic dermatitis kumachepetsedwa ndi 60%.
●Ndi ChiyaniKugwiritsa ntchitoOf Zinc pyrithione?
1. Daily Chemical Field:
Itha kugwiritsidwa ntchito mu 70% ya shampu yotsutsana ndi dandruff, ndi kuchuluka kwa 0,3% -2%;
Zina zodzikongoletsera zimatha kuletsa kugwiritsa ntchito zinki pyrithione ndipo ziyenera kulembedwa kuti "mutsuka mukamaliza". Mukhoza kugwiritsa ntchito mankhwala ena piroctone ethanolamine (OCT).
2. Industrial Anti-Corrosion:
Kusintha kwa anti-fouling: kuphatikizidwa ndi cuprous oxide kuletsa kulumikizidwa kwa barnacle ndikuchepetsa kugwiritsa ntchito mafuta a sitima ndi 12%;
3. Agriculture ndi Zipangizo:
Chitetezo cha mbeu: 0.5% ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ ❖ amateteza nkhungu ndi kuchulukitsa kamere ndi 18%;
Ulusi wa antibacterial: nsalu ya poliyesitala yomezanitsidwa imakhala ndi antibacterial mlingo wa> 99%.
4. Zowonjezera Zachipatala:
Mayeso a zifukwa zitatu (palibe carcinogenicity/teratogenicity/ mutagenicity), amagwiritsidwa ntchito popanga gel osakaniza komanso zokutira zowononga mabakiteriya pazida zamankhwala.
●Malangizo:
Ngakhale pachimake m`kamwa kawopsedweof zinc pyrithionendi otsika (LD₅₀>1000mg/kg mu mbewa), machenjezo azachipatala m'zaka zaposachedwa:
Khungu kawopsedwe: kukhudzana kwa nthawi yayitali kumayambitsa dermatitis, ndipo kukhudzana ndi zikope kungayambitse conjunctivitis;
Mtheradi contraindications:
→ Khungu losweka (kuthekera kumawonjezeka katatu, zomwe zimapangitsa kuti pakhale kuwonetseredwa kwadongosolo);
→ Amayi oyembekezera ndi ana (zotchinga magazi ndi ubongo zikusowa);
Kuyanjana kwa mankhwala: Pewani kugwiritsa ntchito pamodzi ndi EDTA (chelating zinc ions amachepetsa mphamvu ya mankhwala).
