●Yini? I-Zinc Pyrithione?
I-Zinc pyrithione (ZPT) i-organic zinc complex enefomula ye-molecular C₁₀H₈N₂O₂S₂Zn (isisindo se-molecular 317.7). Igama laso livela ezithakweni zezimpande zemvelo zesitshalo i-Annaceae i-Polyalthia nemoralis, kodwa imboni yesimanje yamukele ukuhlanganiswa kwamakhemikhali ukuze isikhiqize. Ngo-2024, inqubo yaseChina enelungelo lobunikazi yagqekeza ibhodlela lokuhlanzeka, kwathi ukungcola kwe-crotonic acid kwalawulwa ngaphansi kwe-16ppm ngokusebenzisa i-methanol-acetone graded crystallization, futhi ubumsulwa bebanga lezemithi lwenyuka lwaba ngu-99.5%.
Izakhiwo zomzimba namakhemikhali:
Ukubukeka nokuncibilika: i-crystalline powder emhlophe kuya kokuphuzi kancane, cishe ayincibiliki emanzini (<0.1g/100mL), incibilika kancane ku-ethanol, ukuncibilika ku-polyethylene glycol kungafinyelela ku-2000mg/kg;
Ukushiyeka kokuzinza: ukuzwela ekukhanyeni kanye nama-oxidants, onakaliswa kalula ukukhanya kwe-ultraviolet, ukupakishwa okunsundu kuyadingeka; ukuhluleka kokuhlukanisa ku-pH <4.5 noma> 9.5, i-pH elungile ingu-4.5-9.5;
Iphuzu elibalulekile lokubola kokushisa: lizinzile amahora angu-120 ku-100℃, kodwa libola ngokushesha ngaphezu kuka-240℃;
Ukungahambisani: kwehla ngama-cationic surfactants, ama-chelates futhi ashintshe umbala nge-iron/copper ions (ngisho ne-1ppm ingabangela umkhiqizo ukuba ube phuzi).
●ZiyiniIzinzuzoKwe I-Zinc Pyrithione ?
I-ZPT izuza ukuvala inzalo okubanzi (okusebenza ngokumelene nezinhlobo ezingu-32 zamagciwane) ngokusebenzisa indlela yokushintshanisa i-ion eyingqayizivele, ikakhulukazi ku-Malassezia, umgebengu we-dandruff, ene-MIC ephansi njengo-8ppm:
1. Ukubhujiswa Kwe-Ion Gradient
Endaweni ene-acidic, i-H⁺ ifakwa kubhaktheriya bese i-K⁺ iphuma, futhi endaweni ene-alkaline, i-Na⁺/Mg²⁺ iyashintshwa, ehlakaza uhlelo lokuthutha izakhi ezincane;
2. Ukuhlukana Kwengqamuzana Yeseli
Ukufaka ku-bilayer ye-phospholipid, okwandisa ulwelwesi ukungena futhi kubangele ukuvuza kwempahla ye-intracellular;
3. Ukuvimbela Umsebenzi We-Enzyme
Ukuvimbela uchungechunge lwezokuthutha lwama-electron kanye nokuvimbela ama-enzyme abalulekile we-energy metabolism (njenge-ATP synthase).
Ukuqinisekiswa komtholampilo: Ngemuva kokusebenzisa i-shampoo equkethe u-1.5%zincpi-yrithioneamaviki angu-4, i-dandruff iyancipha ngo-90%, futhi izinga lokuphindaphinda kwe-seborrheic dermatitis liyancipha ngo-60%.
●ZiyiniIsiceloOf I-Zinc Pyrithione?
1. I-Daily Chemical Field:
Ingasetshenziswa ku-70% ye-shampoo yokulwa ne-dandruff, enenani elingeziwe lika-0.3% -2%;
Eminye imikhiqizo yezimonyo ingakhawulela ukusetshenziswa kwe-zinc pyrithione futhi idinga ukumakwa "ihlanza ngemva kokusetshenziswa". Ungasebenzisa omunye umkhiqizo we-piroctone ethanolamine (OCT).
2. I-Industrial Anti-Corrosion:
I-anti-fouling revolution: ihlanganiswe ne-cuprous oxide ukuvimbela okunamathiselwe kwe-barnacle nokunciphisa ukusetshenziswa kukaphethiloli womkhumbi ngo-12%;
3. Ezolimo Nezinto Zokusebenza:
Ukuvikelwa kwembewu: 0.5% i-agent enamathelayo ivimbela isikhutha futhi ikhuphule izinga lokuhluma ngo-18%;
Ifayibha elwa namagciwane: Indwangu ye-polyester exhunyelelwe inezinga lokulwa namagciwane elingu->99%.
4. Isandiso Sezokwelapha:
Ukuhlolwa kwezimbangela ezintathu ukuthi awunayo (ayikho i-carcinogenicity/teratogenicity/mutagenicity), esetshenziselwa ijeli yezinduna nokumbozwa kwe-antibacterial yamadivayisi wezokwelapha.
●Amathiphu:
Nakuba ubuthi acute ngomlomoof i-zinc pyrithioneiphansi (LD₅₀>1000mg/kg kumagundane), izexwayiso zomtholampilo eminyakeni yakamuva:
Ubuthi besikhumba: ukuthintana isikhathi eside kubangela i-allergic dermatitis, futhi ukuthintana kwejwabu leso kungabangela i-conjunctivitis;
Contraindications ngokuphelele:
→ Isikhumba esiphukile (ukungena kwamanzi kukhuphuka izikhathi ezi-3, okuholela ekuvezweni kwesistimu);
→ Abesifazane abakhulelwe nezingane (idatha yokungena kwesithiyo segazi nobuchopho ayikho);
Ukusebenzisana kwezidakamizwa: Gwema ukusetshenziswa okuhlangene ne-EDTA (i-chelating zinc ions kunciphisa ukusebenza kwezidakamizwa).
