Triphenyl Phosphate (TPP), tseem hu ua TPHP, yog ib qho organophosphorus compound dav siv los ua ib qhonplaim retardantthiabyas yas. Nrog rau keeb kwm ntawm kev siv cov yas, PVC, roj hmab, txheej, cov khoom siv hluav taws xob thiab lwm yam khoom siv polymer-raws li cov khoom, TPP tau dhau los ua cov nplaim hluav taws xob phosphate ester hauv kev lag luam.
Txawm li cas los xij, nws txoj kev siv dav dav kuj tau ua rau muaj kev tshawb fawb thiab kev tswj hwm. Cov kws tshawb fawb tau tshawb xyuas qhov muaj TPP thiab nws cov metabolites hauv ib puag ncig thiab hauv tib neeg cov qauv lom neeg, thaum muaj kev txhawj xeeb txog nws qhov muaj peev xwm endocrine- cuam tshuam cov khoom tau ua rau muaj kev txhim kho tshiab. Rau cov chaw tsim khoom thiab cov neeg yuav khoom tshuaj, kev nkag siab ob qho tib si kev siv thiab kev tswj hwm ntawm TPP yog li ntawd tseem ceeb dua.
Triphenyl Phosphate yog dab tsi?
Triphenyl Phosphate, nrog CAS Tsis yog . 115-86-6, yog phosphate ester uas feem ntau muab los ua cov khoom siv dawb crystalline. Nws yog feem ntau yog siv los ua ib qho additive hauv polymer formulations, qhov chaw uas nws muaj peev xwm muab nplaim hluav taws- retardant zog thaum tseem ua raws li ib tug plasticizer.
Raws li ib tugTPP nplaim retardant, nws tuaj yeem pab txo cov nplaim hluav taws xob ntawm cov txheej txheem polymer uas tsim nyog. Nws cov nyhuv plasticizing kuj tseem tuaj yeem txhim kho kev yooj yim thiab cuam tshuam rau kev ua cov yam ntxwv ntawm qee cov ntaub ntawv. TPP tau siv rau hauv cov ntawv thov uas suav nrog PVC, cellulose-raws li resins, ntuj thiab hluavtaws roj hmab, yas, txheej thiab cov khoom siv hluav taws xob.Vim tias TPP feem ntau muab tso rau hauv cov ntaub ntawv uas yog ib qho ntxiv es tsis yog tshuaj lom neeg rau cov polymer, nws muaj peev xwm tsiv teb tsaws thiab tso tawm tau dhau los ua kev tshawb fawb ntawm ib puag ncig thiab tshuaj lom neeg.
Vim li cas TPP thiaj li muaj kev txhawj xeeb txog kev noj qab haus huv?
Kev txaus siab rau TPP cov txiaj ntsig kev noj qab haus huv tau nce ntxiv raws li kev tshawb fawb tau txheeb xyuas TPP lossis nws cov metabolites hauv cov qauv sib txawv ntawm ib puag ncig thiab lom neeg.Ib qho tseem ceeb metabolite yogDiphenyl Phosphate (DPP), uas feem ntau yog siv los ua biomarker thaum kawm txog tib neeg raug rau TPP. Kev kuaj pom ntawm DPP hauv cov zis kuaj qhia tias tib neeg tuaj yeem raug TPP los ntawm kev sib txawv ntawm ib puag ncig thiab cov neeg siv khoom- cov khoom lag luam.
Txawm li cas los xij, kev kuaj TPP lossis DPP hauv cov qauv tshuaj lom neeg tsis yog los ntawm nws tus kheej qhia tias qee qhov kev kis tus kab mob yuav ua rau muaj kab mob tshwj xeeb lossis kev noj qab haus huv. Qhov kev pheej hmoo yuav nyob ntawm cov yam xws li kev nthuav tawm, lub sijhawm, txoj kev raug thiab cov pov thawj toxicological muaj.
Qhov kev sib txawv no yog qhov tseem ceeb thaum tham txog TPP toxicity. Kev tshawb fawb tshawb fawb txuas ntxiv tshawb xyuas nws cov txiaj ntsig lom neeg muaj peev xwm, suav nrog kev ua haujlwm ntawm endocrine, thaum cov thawj coj tswj hwm tshuaj xyuas cov pov thawj muaj los ntawm kev tsim tshuaj lom neeg- cov qauv kev nyab xeeb.
TPP hauv Nail Polish
Txawm hais tias TPP feem ntau cuam tshuam nrog cov ntawv thov kev lag luam, nws cov keeb kwm siv hauv qee cov neeg siv khoom tau nyiam cov neeg siv khoom ntau. Ib qho piv txwv tseem ceeb yog ntsia thawv polish.Triphenyl Phosphatetau siv los ua plasticizer hauv qee tus ntsia thawv- polish formulations los txhim kho kev yooj yim thiab ua haujlwm ntev. Vim tias cov ntsia thawv polish yog siv ncaj qha rau ntawm tus ntsia thawv thiab tseem nyob hauv kev sib cuag nrog cov tawv nqaij ib puag ncig, cov kws tshawb fawb tau tshuaj xyuas seb cov khoom no puas tuaj yeem ua rau tib neeg raug.
Qee qhov kev tshawb fawb tau kuaj pom TPP hauv cov ntsia hlau- cov khoom polish. Txawm li cas los xij, qhov concentration tam sim no hauv ib yam khoom yuav tsum tsis txhob sib npaug ncaj qha nrog tus nqi absorbed los ntawm tib neeg lub cev. Qhov tshwm sim tiag tiag nyob ntawm qhov kev tsim, qhov ntau npaum li cas, qhov siv thiab ntau npaum li cas.
Cov neeg siv khoom kuj tseem yuav ntsib cov ntsiab lus xws li "3-Free," "5-Free" lossis "10-Free" thaum xaiv cov ntsia thawv polish. Cov ntawv sau no feem ntau qhia tias qee cov tshuaj tau raug tshem tawm los ntawm kev tsim, tab sis lawv cov ntsiab lus tsis yog tag nrho cov qauv thoob plaws txhua hom thiab kev lag luam. Kev tshuaj xyuas cov ntaub ntawv muaj tseeb yog li kev ntseeg tau ntau dua li tso siab rau ntawm daim ntawv lo "N-Dawb".
TPP thiab REACH Txoj Cai
Ib qho kev txhim kho tseem ceeb tshaj plaws tsis ntev los no hais txogTriphenyl Phosphate tshwm sim hauv Europe. Thaum Lub Kaum Ib Hlis 7, 2024, European Chemicals Agency (ECHA) tau ntxiv TPP, CAS No. 115-86-6, mus rau REACH SVHC Cov Npe Npe raws li nws tau txheeb xyuas ib puag ncig endocrine- cuam tshuam cov khoom.
Qhov tseem ceeb, suav nrog SVHC Cov Neeg Sib Tw Npe tsis tau txhais hais tias TPP tau raug txwv tam sim ntawd thoob plaws European Union. Hloov chaw, nyob ntawm qhov xav tau, hom khoom thiab cov khoom siv- cov xwm txheej ntawm cov saw hlau, SVHC cov xwm txheej tuaj yeem tsim cov ntaub ntawv tshwj xeeb thiab kev sib txuas lus raws li REACH.
Rau cov tuam txhab uas muag los yog muab TPP rau cov lag luam nyob sab Europe, nws yog ib qho tseem ceeb los saib xyuas qhov tseeb TPP REACH raws li txoj cai, tswj cov ntaub ntawv tsim nyog thiab sib txuas lus cov ntaub ntawv cuam tshuam thoob plaws hauv cov khoom siv.
Cov neeg yuav khoom TPP yuav tsum xav txog dab tsi?
Rau industrial buyers, xaiv aTriphenyl Phosphatee tus neeg muag khoom yuav tsum koom nrog ntau tshaj qhov sib piv tus nqi thiab purity. Cov khoom lag luam zoo ib yam yog qhov tseem ceeb vim tias qhov sib txawv ntawm purity los yog lub cev yam ntxwv tuaj yeem cuam tshuam rau kev ua haujlwm ntawm polymer thiab kev ua haujlwm ntawm cov khoom kawg. Cov neeg yuav khoom yuav tsum xav txog qhov muaj COA, SDS / MSDS, cov khoom specifications thiab cov ntaub ntawv tswj hwm, tshwj xeeb tshaj yog thaum TPP yog npaj rau kev lag luam thoob ntiaj teb. Kev sib raug zoo ntawm TPP nrog lub hom phiaj polymer system, kev ua haujlwm thiab cov nplaim hluav taws yuav tsum tau ua haujlwm -kev ua haujlwm tsis zoo yuav tsum raug ntsuas ua ntej kev lag luam siv.
Rau cov tuam txhab muab khoom muag rau cov teb chaws Europe, kev ua raws cai tau dhau los ua ib feem tseem ceeb ntawm TPP qhov kev txiav txim siab.Triphenyl Phosphate (TPP) tseem yog ib qho tsim phosphate ester nplaim taws retardant thiab plasticizer nrog cov ntawv thov hla plastics, PVC, roj hmab, coatings thiab lwm yam polymer-raws li cov ntaub ntawv. Tib lub sij hawm, nws ib puag ncig thiab toxicological profile tau nyiam kev loj hlob. Ntxiv ntawm TPP rau lubREACH SVHC Cov neeg sib twDaim ntawv teev npe hauv 2024 sawv cev rau kev tswj hwm kev txhim kho tseem ceeb thiab qhia txog qhov xav tau rau cov tuam txhab lag luam thiab cov neeg yuav khoom tshuaj kom nyob twj ywm paub txog kev hloov pauv.
Rau kev lag luam siv lossis kev lag luam TPP thoob ntiaj teb,ib lub tswv yim kev lav phib xaub yuav tsum txiav txim siab tsis yog tsuas yog kev ua tau zoo thiab cov khoom lag luam zoo xwb, tab sis kuj tseem muaj txoj cai tswjfwm, cov ntaub ntawv thiab cov khoom siv -chain kev sib txuas lus.
