Xaiv cov ntaub so me nyuam nyob ntawm ntau yam. Qee tus neeg saib xyuas tsuas yog txhawj xeeb txog pes tsawg ntawm cov khoom siv cog qoob loo uas muaj cov ntaub so. Lwm tus yuav txhawj xeeb ntau dua nrog kev ntxhib los mos thiab tsw.
Hauv kev xaiv cov ntaub so me nyuam, nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom xyaw ntuj tshaj plaws, tseem muaj txiaj ntsig zoo. Piv txwv li, phenoxyethanol yog ib qho kev siv tshuaj tua kab mob, tab sis nws tau txuas nrog ntau yam kev txhawj xeeb txog kev noj qab haus huv.
Lwm cov tshuaj tiv thaiv uas feem ntau siv rau hauv cov menyuam yaus cov ntaub so yog parabens, uas tau txuas rau endocrine cuam tshuam, mob qog noj ntshav, thiab ua xua. Phenoxyethanol yog suav hais tias yog ib qho khoom siv ruaj ntseg dua li parabens.
Lwm cov khoom uas yuav tsum tau saib xyuas hauv cov ntaub so me nyuam yog phthalates, uas feem ntau siv los ua cov khoom xyaw tshuaj tsw qab. Phthalates yog cov kab mob carcinogenic thiab cov tshuaj tua kab mob. Lawv tsis tau teev nyob rau hauv daim ntawv lo, tab sis lawv feem ntau pom muaj nyob rau hauv cov tshuaj tsw qab.
Ntau cov ntaub so me nyuam kuj tseem muaj propylene glycol, uas txuas nrog lub cev muaj zog. Propylene glycol yog siv rau hauv cov tshuaj ntxuav tes thiab tshuaj pleev ib ce, tab sis tsis tsim nyog rau cov ntaub so me nyuam.
Lwm cov khoom uas yuav tsum tau saib xyuas hauv cov ntaub so me nyuam yog sodium benzoate, uas tuaj yeem ua rau khaus ntawm cov menyuam mos. Sodium benzoate yog cov khoom siv hluavtaws thiab muaj cov ntsiab lus siab ntawm nws tuaj yeem ua rau muaj kev phom sij rau lub cev.
Thaum kawg, cov kab mob hu ua 1,4-dioxane tuaj yeem pom hauv cov ntaub so me nyuam. Qhov no yog ib qho byproduct ntawm cov txheej txheem ethoxylation. Cov txheej txheem no sim ua kom hnyav roj av-raws li cov khoom xyaw kom tsis txhob khaus. Txawm li cas los xij, tsis muaj ethylene oxide tuaj yeem nyob hauv cov khoom tiav.
