Siv cov tshuaj pleev ib ce kom zoo

Tshuaj pleev ib ce yog ib feem ntawm lub neej txhua hnub rau tus txiv neej thiab poj niam. Ntau tus neeg xav ua kom pom qhov zoo thiab xav zoo, thiab lawv siv cov tshuaj pleev ib ce kom ua tiav qhov no. Lub Chaw Haujlwm Pabcuam Ib Puag Ncig (EWG), uas yog lub koom haum ua haujlwm tau txais txiaj ntsig los qhuab qhia cov neeg siv khoom hauv cov ntsiab lus ntawm cov khoom lag luam kom zoo nkauj, hais tias cov poj niam siv qhov nruab nrab ntawm 12 cov khoom tu tus kheej hauv ib hnub, thiab cov txiv neej siv li ib nrab ntawd.

Vim tias cov khoom siv tshuaj pleev ib ce nthuav dav hauv zej zog, nws yog qhov tseem ceeb uas yuav tau ua kom paub thiab cov neeg siv khoom muaj kev txawj ntse. Kawm paub dab tsi hauv cov tshuaj pleev ib ce thiab yuav ua li cas lawv cuam tshuam rau koj thiab ib puag ncig.

FDA, daim ntawv lo, thiab kev zoo nkauj khoom nyab xeeb

Ntau tus neeg nrhiav cov khoom lag luam zoo nkauj uas tau tsim los ntawm kev noj qab haus huv, tsis muaj cov khoom xyaw. Hmoov tsis zoo, nws tsis yooj yim rau cov neeg tau txais kev pab kom paub txog hom twg yog cov muaj txiaj ntsig zoo rau lawv thiab ib puag ncig. Cov ntawv thov uas lees tias cov khoom yog “ntsuab,” “ntuj tsim,” lossis “organic” tsis muaj kev ntseeg tau. Tsis muaj tsoomfwv lub koomhaum ua lub luag haujlwm los saib xyuas lossis tsim txoj cai tsim khoom los ntawm cov tshuaj pleev ib ce.

Tsoom Fwv Tebchaws Asmeskas Khoom Noj thiab Tshuaj (FDA) tsis muaj lub zog los soj ntsuam cov tshuaj pleev ib ce kom zoo ib yam li zaub mov thiab yeeb tshuaj. FDA muaj qee txoj cai lij choj tshaj li tshuaj pleev ib ce. Txawm li cas los xij, cov khoom zoo nkauj zoo nkauj thiab lawv cov khoom xyaw (tshwj tsis yog cov xim hloov xim) tsis raug pom zoo los ntawm FDA pom zoo uantej.

Hauv lwm lo lus, FDA tsis tuaj xyuas seb cov khoom uas lees tias "100 feem pua ​​organic" yog 100 feem pua ​​organic. Ib qho ntxiv, FDA yuav tsis tuaj yeem rov nco txog cov khoom lag luam zoo nkauj.

Nws yog ib qho tseem ceeb uas koj, tus neeg tau txais kev pab, paub thiab yuav cov khoom lag luam uas muaj kev nyab xeeb thiab zoo rau koj thiab ib puag ncig. Nco ntsoov tias qee cov tshuaj muaj kuab lom nyob rau qee yam khoom zoo nkauj tuaj yeem yog tshuaj lom.

Nkag siab txog cov khoom pleev "pleev"

Txhawm rau pab koj kom txiav txim siab tau txais txiaj ntsig zoo, ntawm no yog plaub yam tseem ceeb ntawm cov khoom siv hauv kev puas tsuaj uas siv hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej:

Cov neeg tshaj lij

Raws li Royal Society of Chemistry, surfactants pom muaj nyob hauv cov khoom siv rau kev ntxuav. Lawv tawg ua cov roj pleev cov kuab tshuaj ua los ntawm daim tawv nqaij kom lawv tuaj yeem muab dej los ntxuav. Cov tshuaj pleev ua ke yog ua ke nrog cov quav ntxiv xws li dyes, naj hoom, thiab ntsev hauv cov khoom xws li lub hauv paus, da dej gel, zawv plaub hau, thiab pleev lub cev. Lawv cov khoom tuab, cia lawv kis tusyees thiab ntxuav thiab ua npuas ncauj.

Cua txias polymers

Cov no khaws cov dej noo ntawm daim tawv nqaij los yog hauv plaub hau. Glycerin, cov khoom xyaw ntuj ntawm cov roj zaub thiab cov tsiaj rog, yog ua kom sib haum hauv kev lag luam tshuaj pleev ib ce. Nws yog qhov qub tshaj plaws, pheej yig tshaj, thiab nrov tshaj plaws txias polymer.

Cov tshuab ua kom txias polymers siv nyob rau hauv plaub hau khoom kom nyiam dej thiab muag kom plaub hau thaum hle plaub hau. Lawv khaws cov khoom lag luam kom qhuav thiab tswj cov tshuaj tsw qab kom cov ntxhiab tsw txhob pom los ntawm cov taub yas yas lossis raj. Lawv kuj ua cov khoom xws li cov tshuaj zawv plaub hau kom du thiab plam, thiab lawv tiv thaiv lawv kom tsis txhob lo rau koj txhais tes.

Khaws cia

Cov tshuaj muaj yees muaj ntxiv uas tshwj xeeb txhawj xeeb txog cov neeg siv khoom. Lawv tau siv los ua kom cov kab mob loj hlob qeeb thiab ua kom ntev lub khoom txee. Qhov no tuaj yeem khaws cov khoom los ntawm qhov ua rau kis kab mob ntawm daim tawv nqaij lossis qhov muag. Kev lag luam tshuaj pleev ib ce yog sim nrog kev kho tus kheej li tshuaj pleev ib ce, uas siv cov roj cog ntoo lossis rho cov khoom los ua cov tshuaj tua kab mob ib txwm muaj. Txawm li cas los xij, cov no tuaj yeem ua rau tawv nqaij lossis ua rau ua xua. Ntau tus muaj ntxhiab tsw muaj zog uas tuaj yeem tsis kaj siab.

Cov tshuaj tsw qab

Cov tshuaj tsw qab tuaj yeem yog qhov phom sij tshaj plaws ntawm cov khoom lag luam kev zoo nkauj. Cov tshuaj tsw qab feem ntau muaj cov tshuaj uas yuav ua rau muaj kev fab tshuaj. Koj tuaj yeem xav xav txog kom zam ib qho khoom uas muaj cov kab lus "tshuaj tsw qab" rau hauv nws cov npe ntawm cov khoom xyaw.

Kev txwv cov khoom xyaw

Raws li FDA, cov khoom xyaw hauv qab no raug txwv tsis pub siv tshuaj pleev ib ce:

• bithionol
• chlorofluorocarbon cov khoom tshaj tawm
• chloroform
• halogenated salicylanilides, di-, tri-, metabolismromsalan thiab tetrachlorosalicylanilide
• methylene chloride
• yas tshuaj dawb
• zirconium-muaj complexes
• txwv tsis pub cov khoom tsiaj nyeg

Txwv cov khoom xyaw

Lub FDA tseem teev cov khoom no, uas tej zaum yuav siv tab sis raug txwv:

• xov hexachlorophene
• mercury cov sib txuas
• cov tshuaj pleev thaiv hnub siv hauv cov tshuaj pleev ib ce

Lwm yam kev txwv

EWG tseem qhia ntxiv kom tsis txhob ntxiv, suav nrog:

• benzalkonium chloride
• BHA (butylated hydroxyanisole)
• cov roj av tar plaub hau dyes thiab lwm cov xyaw ua lag luam tar, xws li aminophenol, diaminobenzene, thiab phenylenediamine
• DMDM hydantoin thiab bronopol
• formaldehyde
• cov khoom xyaw uas sau ua "tshuaj tsw qab"
• hydroquinone
• methylisothiazolinone thiab methylchloroisothiazolinone
• oxygenbenzone
• parabens, propyl, isopropyl, butyl, thiab isobutylparabens
• PEG / ceteareth / polyethylene sib txuas
• roj av distillates
• phthalates
• resorcinol
• retinyl palmitate thiab retinol (vitamin A)
• toluene
• triclosan thiab triclocarban

Cov kev txhawj xeeb txog kev ntim khoom zoo nkauj

Xaiv cov pleev ua kom zoo nkauj kuj txhais tau tias xaiv kev ntim khoom uas muaj kev nyab xeeb rau koj thiab kev noj qab haus huv rau lub ntiaj teb. Lub taub hau nrog qhov ncauj qhib tau tuaj yeem cuam tshuam nrog cov kab mob. Airless ntim, uas tsis pub cov kab mob tuaj yeem yug me nyuam, yog qhov zoo dua. Cov twj tso kua mis nrog txoj kev sib tshooj ib leeg tuaj yeem ua kom huab cua nkag los rau hauv lub pob qhib, ua rau muaj paug tsis yooj yim dua. Cov txheej txheem kev ua haujlwm ceev faj khaws cov khoom tsis huv thaum nws nkag mus rau hauv lub raj mis lossis lub hwj.

Outlook

Tshuaj pleev ib ce yog ib feem ntawm lub neej rau ntau tus neeg, thiab lawv txoj kev lag luam tuaj yeem yuam kev. Yog tias koj siv cov tshuaj pleev ib ce lossis cov khoom tu tus kheej, qhia kom meej qhov tseeb uas nyob hauv lawv. Los ntawm kev nyeem cov ntawv cim thiab ua qee qhov kev tshawb fawb koj tuaj yeem txiav txim siab kev kawm, kev noj qab haus huv thaum mus yuav khoom thiab siv cov khoom zoo nkauj.
