Lub hom phiaj ntawm cov additives yog txo los ntawm lipolysis, thiab ntawm cov hoob kawm, tus tsim ntawm npaus. Alas, peb yog tag nrho cov accustomed mus, tias yog hais tias tsuaj zawv plaub hau tsis ua npuas ncauj, ces rau nws hais tias ib yam dab tsi yog tsis ncaj ncees lawm.

Feem ntau cov paub sodium lauryl sulfate. Nws yog ib tug byproduct ntawm cov roj av refining. Qhov zoo xws li siab detergency nyob rau hauv dej ntawm tej kub (txheejtxheem txhais tau tias rau advertising tais diav). Nws yuav zoo li - ib tug zoo meej surfactants. Txawm li cas los, tsis yog txhua txhua thiaj li yooj yim. Lauryl txav lipid tiv thaiv txheej ntawm tib neeg daim tawv nqaij, ces cov voos tsis ua ntev tos.

Nyob rau hauv txhua rooj plaub, yog tias muaj ntau ntau yam rau xaiv los ntawm, lub xum yog tau sodium laureth sulfate, es nws ze "txheeb ze" - lauryl sulfate.

Nyob rau hauv thiaj li yuav nyob twj ywm muaj kev sib tw, ib co manufacturers tau txhab lawv txoj kev khwv ntawm cov khoom, cov los yog kiag li tso tseg kev siv ntawm cov saum toj no surfactant. Tseem li lauryl thiab sodium laureth sulfate yog tawv surfactants.

Lawv yog cov niaj hnub lwm txoj rau lub "mos mos" tebchaw uas tsis ua ntev li daim tawv nqaij voos. Cov paub muaj nqis ntsoov teev cocamidopropyl betaine thiab glycerol monostearate. Qhov no tshiab tiam ntawm xab npum surfactants uas haum rau cov neeg uas muaj cov tawv.

Tej zaum nyob rau hauv lub rhawv ntawm khw muag khoom noj tshuaj pleev ib ce muaj peev xwm ua tau raws li tradeoffs, thaum lub concentration ntawm thawj surfactant (sodium laureth los yog sodium lauryl sulphate) yog txo los ntawm qhov sib ntxiv ntawm cocamidopropyl betaine.
