Tsis ntev tas los no, nrog rau kev tshaj xo luam tawm thiab cov yeeb yaj duab hauv TV, cov tshuaj pleev ib ce manufacturers tau nrog peb los qhia rau peb paub tias lawv cov kab tshiab thiab cov chaw tsis muaj teeb meem: cov kis kab mob, sulfates thiab silicones. Tab sis yog cov tshuaj no puas tsim kev puas tsuaj tiag tiag? Cia peb los saib xyuas qhov teeb meem no.
Parabens
Lo lus nug "Lawv noj dab tsi nrog?" Nyob rau hauv cov ntsiab lus ntawm parabens, nws yog qhov tsim nyog los nug cov lus: tom qab tag nrho, peb khoov rau lawv txhua txhua hnub. Thiab peb kuj ntxuav peb tus kheej, peb raug kho thiab faib rau peb tus kheej. Parabens yog ib feem ntawm cov neeg nyiam huv preservatives nyob rau hauv cov cosmetic, zaub mov thiab kev lag luam industries. Lub ntsiab haujlwm ntawm cov esters no tsis yog muab pwm thiab microbes los khom, xws li hauv koj lub qab zib. Raws li txoj cai, parabens ib leeg tsis tuaj yeem ua tau, cov lag luam nyiam ua ke nrog lwm cov tshuaj tivthaiv, vim li no koj tuaj yeem nthuav cov kabmob ntawm cov kabmob uas koj xav tau los tiv thaiv koj lub vaj tse. Thaum lub neej tshiab tsis tuaj yeem tsis tuaj yeem, lub hnub tas sij hawm siv tau txuas ntxiv mus. Qhov no yog qhov thib ob ntawm qhov tseem ceeb ntawm parabens. Kiag li tsis muaj cov tshuaj txhuam hniav, cov khoom yuav ua tau kom nquag mus rau ob peb hnub, thiab txawm tias tom qab ntawd, muaj feem xyuam rau ib qho chaw cia txias. Cov no yog tag nrho lawv, cov sib npaug, muab lub neej ntawm cov txiaj ntsim zoo thiab ua kom muaj sijhawm los ua kom lub chav da dej ua ntej kawg. Ces yog vim li cas lub Paraben dawb ntawv no tshwm sim ntau dua thiab ntau zaus rau cov khoom siv zoo nkauj? Ua ntej, nws yog fashionable. Thiab ob zaug, txawm tias nws cov keeb kwm luv luv, uas tau ua haujlwm ntev li ob peb lub xyoos, cov kab ke tswj tau ntub lawv lub koob npe nrov. Nws yog xyoo 2004. Tus kws tshawb fawb British, raws li ib txwm, tsis so. Lawv kuj nrhiav kev tshawb fawb qhia tias parabens muaj cov khoom txawb ntawm cov nqaij ntawm lub mis. Hauv 18 ntawm 20 cov qog nqaij hlav cancer ntawm lub mis, cov tshuaj no tau pom. Txoj kev tshawb no tsis tau ua pov thawj tias cov khoom no ua rau cov kab mob loj hlob tuaj, tab sis cov qoob loo tseem nyob, thiab kev tsim txom pib ntawm cov kis kab mob. Nws mus kom deb li deb uas thaum lub Kaum Ob Hlis Ntuj 2010, Pawg Ntsib Ua Teb rau EU Consumer Goods tau hais tias: tsis muaj qhov tseem ceeb txaus los tham txog qhov raug mob ntawm propyl thiab butylporaben, tab sis lawv cov concentration hauv cov khoom yuav tsum tau txo ntawm 0.8% 0.19%. Nyob rau hauv lub Peb Hlis 2011, Denmark tau ua thawj lub tebchaws uas txwv tsis pub qee qhov ntawm cov khoom siv no rau cov menyuam yaus tshaj 3 xyoos. Thiab yuav luag tag nrho cov neeg lag luam ntawm deodorants thiab antiperspirants tsis tau lawv los ntawm qhov muaj pes tsawg leeg - xyuas nws thiab nyob rau hauv rooj plaub.
Cov kev tshawb fawb txuas ntxiv, thiab ntawm no koj yuav tsum txiav txim siab seb nws yog leej twg. Yog tias koj xaiv lub chaw pw hav zoov "Tsis muaj parabens," suav tias yuav siv nyiaj rau cov tshuaj pleev ib ce ntau dua. Los yog mus rau lub ntuj rulers ntawm tsoos hom, vim hais tias tam sim no ntau hom ua eco-phooj ywg-nyiaj los thov cov neeg ras txog. Tab sis txawm hais tias koj noj cov ntshav liab dawb, nws tsis txhais hais tias nws yuav tsum muab pov tseg hauv ob hnub, tsuas yog lub cev nyob rau hauv nws yog zaum hloov nrog qee yam kev txuag.
Sulfates
Sulfates yog salts ntawm sulfuric acid. Lawv tau ntxiv rau cov tshuaj pleev ib ce raws li ib qho kev tu thiab ua feem ntau ntawm txij thaum xyoo 1940. Cov neeg tsim khoom tsim rau lawv kom lawv muaj peev xwm txo qhov nro ntawm qhov dej los yog cov chemists ua cuav, ua rau nws ntau dua qub. Tias yog vim li cas sulphates ua rau cov khoom ua npuas ncauj lustrously thiab thiaj li zoo rau tshem tawm impurities. Nrhiav cov kua ntsev no hauv cov tshuaj zawv plaub hau, da dej gels thiab txhua yam ntawm umyvalka. Thiab koj yuav pom lawv hauv koj cov khaub ncaws ntxhua khaub ncaws los yog ntxuav tais diav - uas, koj yuav tsum pom zoo, ua rau koj xav.
Cov teeb meem loj ntawm txhua qhov kev sib cav yog sodium lauryl sulfate SLS (sodium lauryl sulfate) thiab sodium laureth sulfate SLES (sodium laureth sulfate). Unnatural sulfates los ntawm roj av (tsuas yog cov SLS thiab SLES) yog txaus ntshai los ntawm kev txhoj puab heev ntawm cov tshuaj tua kabmob (epidermis). Tom qab tag nrho, cov roj tshuaj yog tuag, thiab tau txais ntawm daim tawv nqaij los yog nkag mus hauv, nws tsis ua rau cov txheej txheem metabolic, ntsig txog, thiab tshem tawm ntawm lub cev tsis yooj yim. Qee cov kev tshawb fawb pom tau tias qhov txuam ntawm sulfates tuaj yeem ua rau mob cancer, tab sis tshwj xeeb tshaj yog cov ntsev no yog txaus ntshai rau cov menyuam yaus thiab tub ntxhais hluas, vim lawv tuaj yeem ua rau qeeb hauv kev loj hlob. Raws li qhov cosmetic sab ntawm qhov teeb meem, cov sulphates purify ntawm daim tawv nqaij thiab cov plaub hau los ntawm oxidation thiab tawm cov zaj duab xis zoo tshaj plaws rau lawv, thiab lawv kuj txov tus qauv ntawm koj curls, yuav provoke plhaw thiab txawm npog. Tsis tas li ntawd, tsis muaj ib tus kws kho mob tsis lees paub tias cov kua ntsev ntawm sulfuric acid ua rau qhov ua rau tsis haum rau lwm yam.
Dua li ntawm tag nrho cov kev ntshai, tsis muaj leej twg xav tias yuav kaw txoj kev mus rau sulphates hauv kev lag luam kev zoo nkauj. Muaj ntau lub teb chaws tsuas pub ib qho kev txwv ntawm lawv qhov kev tsis txaus siab - tsis tshaj li 1%, thiab cov kev tshawb fawb ntawm kev ywj siab hais txog kev tsis sib haum ntawm cov ntsev no. Thaum kawg, niaj hnub qauv muab ib tuj ntawm cov nruab nrab thiab nplua nuj ua kom txo tau kev raug mob ntawm sulphates kom tsawg, thiab tsis txhob kov cov khoom tseem ceeb.
Tsis kam siv tshuaj pleev xim SLS thiab SLES ua rau koj paub, yog tias koj saib txog lub ntiaj teb. Piv txwv, sodium lauryl sulfate yog pom tau hais tias muaj tshuaj lom muaj dej, uas txhais tau hais tias thaum koj mus da dej, koj ntxuav nws cov kua hauv lub dab dej nrog cov gel - cov ntses xws li kev noj mov yuav tsis zoo siab. Tsis tas li ntawd, txhua cov tshuaj pleev ib ce nrog sulfates raug sim hauv cov tsiaj. Tau, tsis yog txhua tus tub scoff ntawm pluag rabbits, tab sis thaum sulfuric acid salts yog siv nyob rau hauv tshuaj pleev ib ce, kev kawm no yuav tsum tau ua. Yuav kom tshem koj lub siab, saib qhov kos cim rau hauv daim ntawv ntawm lub pob ntseg hla.
Tsis npaj txhij mus rau disaccustom rau foaming pleev? Sim ua kom tsawg kawg yog kom tsis txhob ntev mus nrog nws: soaped nws lub taub hau - tsis txhob rub, ntxuav tawm cov tsuaj zawv plaub hau. Tawm hauv lub arsenal ntawm koj txoj kev nyiam gel rau ntxuav, thiab, piv txwv li, cov tshuaj txhuam hloov mus rau bezulfate. Lwm txoj kev yog los saib tej yam ntuj tso analogs nyob rau hauv daim ntawv teev cov khoom xyaw: txiv maj phaub roj (coco sulphates) thiab tawv ntoo ntawm tsob ntoo.
Silicones
Silicones yog tau los ntawm silicon, uas yog, xuab zeb, los ntawm polymerization thiab cov txheej txheem tshuaj. Hu rau lawv ib qho kev tivthaiv tomqab uas cov lus tsis tig. Tab sis txawm hais tias tsis muaj kev tsim txom los ntawm silicons lawv tus kheej, ces tus txheej txheem ntawm lawv cov kev tsim tawm obviously tsis mus rau ib puag ncig rau zoo.
Hauv cov tshuaj pleev xim, cov tshuaj silicones pib ntxiv thaum xyoo 1950: thawj zaug nyob rau hauv tes tes thiab tshuaj pleev, tab sis sai li sai tau, cov tshuaj tua kab mob, cov tshuaj tua kab plaub hau, thiab mousses rau styling ua "silicone". Niaj hnub no koj yuav pom no feem nyob rau hauv yuav luag txhua pawg ntawm cov tshuaj pleev ib ce.
Nyob rau hauv lawv lub sij hawm nyob rau hauv lub teeb ntawm hniav tshuaj pleev ib ce, lawv ua ib tug tiag tiag Revolution, ua ntxoov ntxoo, tonal cream, blush thiab eyeliner ntau ruaj thiab yas. Yog tias koj xav tias cov khoom muaj tus qauv zoo, ceev nrawm, yog tias nws tsis tawm ntawm daim tawv nqaij, ces tej zaum nws yuav muaj cov tshuaj silicones. Tshwj xeeb tshaj yog cov kab mob no tseem ceeb rau cov kua tonalnikov: silicones ua rau lawv khov kom lawv zoo dua nyob rau daim tawv nqaij. Txhais tau rau cov plaub hau yog savored los ntawm no wonder-tivthaiv, rau tus thiab "laug" lub curls. Thiab ntawm no qhov kev xav raug faib: qee cov tuam txhab muaj kev ntseeg tias tsuas yog cov tshuaj muaj peev xwm kho cov plaub hau puas tsuaj, thiab lawv cov neeg tawm tsam sawv cev rau lwm tus - silicones daim ntawv saum npoo, raws li saum tawv taub hau, ib zaj duab xis uas tsis cia oxygen thiab txhua yam tseem ceeb mus rau hauv.
Thiab tsis tau cov nyiaj tau hais tias Silicone dawb tsis muaj qhov chaw rau lwm tus vim - qhov tsis zoo yog vim tsis muaj peev xwm bioaccumulate, uas yog, tsis yog rau decompose, tab sis mus noog. Ecoactivists yaum kom tso cov tshuaj pleev xim rau cov tshuaj no los yog nws cov khoom xyaw, cov tshuaj siloxanes, thiab cov khoom lag luam zoo nkauj nrog cov ntsiab cai txuas hloov cov kua roj los sis cov roj ua kua, cov roj fatty thiab hydrolyzed proteins.
