Chemical yam ntxwv:Daim ntawv molecular ntawm bromo-propanitol yog C₃H₆BrNO₄. Nws yog ib tug dawb mus rau yellowish crystal nyob rau hauv tsos. Nws yaj hauv cov kuab tshuaj xws li dej thiab ethanol. Nws muaj cov tshuaj tua kab mob (tshwj xeeb tshaj yog tiv thaiv Gram-cov kab mob tsis zoo).
Kev siv tseem ceeb:Siv los ua cov tshuaj tua kab mob hauv cov tshuaj pleev ib ce thiab tshuaj zawv plaub hau kom ntev cov khoom txee lub neej los ntawm inhibiting microbial kev loj hlob. Nws cov tshuaj lom neeg tsawg (rau cov tsiaj nyeg) thiab cov tshuaj tua kab mob siab ua rau nws siv dav hauv kev lag luam.
2. Muaj peev xwm txaus ntshai thiab cov kev mob tshwm sim
Irritant:Bromo-propanediol ua rau tawv nqaij thiab qhov muag thiab yuav ua rau tawv nqaij qhuav, khaus lossis kub hnyiab, tshwj xeeb tshaj yog rau cov neeg uas muaj tawv nqaij rhiab heev.
Formaldehyde tso tawm txaus ntshai:Raws li ib tug formaldehyde tso tawm tus neeg saib xyuas preservative, bromo-propanediol yuav tso formaldehyde maj mam thaum lub sij hawm cia los yog siv. Ntev - lub sij hawm raug rau cov tshuaj tsawg ntawm formaldehyde tuaj yeem ua rau tawv taub hau mob, plaub hau poob, thiab txawm tias mob qog noj ntshav (tab sis kev kuaj tsiaj tsis tau pom tias muaj carcinogenicity).
Kev tsis haum tshuaj:Ob peb tus neeg tuaj yeem ua xua rau nws, pom tias yog liab, pob liab liab thiab lwm yam tsos mob, yuav tsum tau nres tam sim ntawd thiab nrhiav kev kho mob.
Cov koob tshuaj ua raws: Hauv cov tshuaj pleev ib ce, tus nqi ntawm bromo-propanediol ntxiv feem ntau yog txwv los ntawm cov cai (xws li European Union txwv qhov concentration rau 0.1%). Cov khoom ua tau raws li kev pheej hmoo tsawg dua nyob rau hauv ib txwm siv.
Kev sib txawv ntawm tus kheej: cov neeg rhiab heev (xws li cov neeg uas muaj kev puas tsuaj ntawm tawv taub hau thiab kev ua xua) yuav tsum tau ceev faj siv cov khoom uas muaj cov khoom no, thiab nws raug nquahu kom ua qhov kev sim hauv zos ua ntej.
Lwm txoj hauv kev: Yog tias koj txhawj xeeb txog qhov txaus ntshai, xaiv cov khoom siv plaub hau uas muaj cov tshuaj tiv thaiv ntuj (potassium sorbate) lossis formaldehyde -cov tshuab dawb.
4. Sib piv nrog lwm cov khoom xyaw
Propylene glycol:Tsis tas li ntawd ib qho tshuaj moisturizer nyob rau hauv cov khoom tu plaub hau, propylene glycol tsis muaj teeb meem rau cov plaub hau thaum siv me me, tab sis ntau dhau tuaj yeem ua rau qhuav lossis khaus.
Selenium disulfide:Lwm cov tshuaj tiv thaiv - dandruff ingredient, tej zaum yuav ua rau cov plaub hau discoloration los yog tawv taub hau khaus, tab sis qhov txaus ntshai yog txawv ntawm bromo-propandiol thiab yuav tsum tau xaiv raws li kev thov
Qhov ncaj qha raug mob rau cov plaub hau thiab tawv taub hau yog tsawg thaum siv raws li kev ua raws, tab sis nws muaj peev xwm irritant, formaldehyde tso tawm txaus ntshai thiab ib puag ncig toxicity yuav tsum tau them sai sai rau. Tsis txhob siv cov tshuaj zawv plaub hau ntev ntev uas muaj cov tshuaj tiv thaiv zoo li no, cov neeg rhiab heev lossis cov poj niam cev xeeb tub tuaj yeem ua qhov tseem ceeb rau lwm txoj hau kev.
