●Dab tsi yog Zinc Pyrithione?
Zinc pyrithione (ZPT) yog cov organic zinc complex nrog cov qauv molecular ntawm C₁₀H₈N₂O₂S₂Zn (molecular hnyav 317.7). Nws lub npe los ntawm cov khoom xyaw hauv paus hauv paus ntawm Annonaceae cog Polyalthia nemoralis, tab sis kev lag luam niaj hnub no tau siv cov tshuaj synthesis los tsim nws. Xyoo 2024, Tuam Tshoj tus txheej txheem patented tsoo los ntawm purity bottleneck, thiab impurity crotonic acid tau tswj qis dua 16ppm los ntawm methanol-acetone graded crystallization, thiab qib tshuaj purity tau nce mus rau 99.5%.
Lub cev thiab tshuaj muaj zog:
Cov tsos thiab solubility: dawb mus rau me ntsis daj crystalline hmoov, yuav luag insoluble nyob rau hauv dej (<0.1g / 100mL), me ntsis soluble nyob rau hauv ethanol, solubility nyob rau hauv polyethylene glycol tuaj yeem ncav cuag 2000mg / kg;
Stability shortcomings: rhiab rau lub teeb thiab oxidants, yooj yim degraded los ntawm ultraviolet lub teeb, xim av ntim yuav tsum tau; dissociation tsis ua hauj lwm ntawm pH <4.5 los yog> 9.5, zoo pH yog 4.5-9.5;
Thermal decomposition tseem ceeb point: ruaj khov rau 120 teev ntawm 100 ℃, tab sis decomposes sai tshaj 240 ℃;
Incompatibility: precipitates nrog cationic surfactants, chelates thiab discolors nrog hlau / tooj liab ions (txawm 1ppm tuaj yeem ua rau cov khoom tig daj).
●Dab tsi yog CovCov txiaj ntsigNtawm Zinc Pyrithione ?
ZPT ua tiav broad-spectrum sterilization (zoo tawm tsam 32 hom kab mob) los ntawm kev sib pauv ion tshwj xeeb, tshwj xeeb tshaj yog rau Malassezia, tus neeg ua txhaum ntawm dandruff, nrog MIC tsawg li 8ppm:
1. Ion Gradient Kev puas tsuaj
Nyob rau hauv ib puag ncig acidic, H⁺ yog nkag mus rau hauv cov kab mob thiab K⁺ yog cov zis, thiab nyob rau hauv ib tug alkaline ib puag ncig, Na⁺ / Mg²⁺ yog hloov, uas disintegrates lub microbial nutrient thauj system;
2. Cell Membrane tawg
Ntxig rau hauv lub phospholipid bilayer, nce daim nyias nyias permeability thiab ua rau intracellular cov ntaub ntawv to;
3. Enzyme Activity Inhibition
Thaiv cov saw hlau thauj electron thiab inhibiting cov enzymes tseem ceeb ntawm lub zog metabolism (xws li ATP synthase).
Kev soj ntsuam xyuas: Tom qab siv tshuaj zawv plaub hau muaj 1.5%zincpyrithionerau 4 lub lis piam, dandruff txo los ntawm 90%, thiab tus nqi rov qab ntawm seborrheic dermatitis yog txo los ntawm 60%.
●Dab tsi yog CovDaim ntawv thovOf Zinc Pyrithione?
1. Txhua hnub Chemical Field:
Nws tuaj yeem siv tau hauv 70% ntawm cov tshuaj zawv plaub hau los tiv thaiv dandruff, nrog rau qhov sib ntxiv ntawm 0.3% -2%;
Qee cov khoom siv tshuaj pleev ib ce tuaj yeem txwv tsis pub siv zinc pyrithione thiab yuav tsum tau muab cim "ntxuav tom qab siv". Koj tuaj yeem siv lwm cov khoom lag luam piroctone ethanolamine (OCT).
2. Muaj Anti-Corrosion:
Anti-fouling kiv puag ncig: compounded nrog cuprous oxide los inhibit barnacle txuas thiab txo cov nkoj roj noj los ntawm 12%;
3. Kev Ua Liaj Ua Teb Thiab Cov Khoom Siv:
Kev tiv thaiv cov noob: 0.5% coating agent tiv thaiv mildew thiab nce germination tus nqi los ntawm 18%;
Antibacterial fiber: grafted polyester ntaub muaj cov kab mob tua kab mob ntawm> 99%.
4. Kev Kho Mob Ntxiv:
Peb-ua rau kuaj tsis zoo (tsis muaj carcinogenicity / teratogenicity / mutagenicity), siv rau pob txuv gel thiab tshuaj tua kab mob ntawm cov khoom siv kho mob.
●Tswv yim:
Txawm hais tias mob qhov ncauj toxicityof zinc pyrithionetsis tshua muaj (LD₅₀> 1000mg / kg hauv nas), cov lus ceeb toom kev kho mob hauv xyoo tas los no:
Kev mob toxicity ntawm daim tawv nqaij: kev sib cuag mus ntev ua rau muaj kev tsis haum dermatitis, thiab qhov muag ntawm daim tawv muag tuaj yeem ua rau mob conjunctivitis;
Tsis muaj contraindications:
→ Cov tawv nqaij tawg (permeability nce 3 zaug, ua rau muaj kev cuam tshuam rau lub cev);
→ Cov poj niam cev xeeb tub thiab cov menyuam yaus (cov ntaub ntawv ntshav-hlwb thaiv kev nkag mus tsis tau);
Kev sib cuam tshuam tshuaj: Tsis txhob siv ua ke nrog EDTA (chelating zinc ions txo cov tshuaj siv tau).
