Cov txheej txheem tsim tshuaj pleev thaiv hnub

Cov txheej txheem tsim khoom ntawmtshuaj pleev thaiv hnubmuaj ntau kauj ruam, suav nrog kev xaiv cov khoom siv raw, kev sib tov, ntxiv cov tshuaj tiv thaiv UV, xim, ntim hauv lub raj mis, thiab lwm yam.

Ua ntej, thawj kauj ruam hauv kev uatshuaj pleev thaiv hnubyog xaiv cov khoom siv raw. Cov txheej txheem no suav nrog kev xaiv ntau yam khoom siv raw xws li cov tshuaj pleev thaiv hnub uas nqus tau zoo, cov hauv paus tsim uas txhawb kev nqus, cov tshuaj emulsifiers thiab cov tshuaj emollients kom tswj tau qhov zoo tshaj plaws tiv thaiv UV. Tom ntej no, cov khoom siv raw xaiv tau sib xyaw thiab zom kom ua ib qho kev daws teeb meem kom ntseeg tau tias txhua yam khoom siv raw tuaj yeem yaj tag thiab nqus mus rau hauv cov tshuaj, yog li ua tiav qhov zoo tiv thaiv UV. Cov tshuaj tiv thaiv UV tom qab ntawd raug ntxiv rau hauv cov tshuaj sib xyaw, thiab cov kauj ruam no ua rau cov tshuaj pleev thaiv hnub muaj kev tiv thaiv UV. Tom qab ntawd, cov tshuaj pleev thaiv hnub yuav muaj xim thiab cov xim tsim nyog yuav raug ntxiv kom nws zoo nkauj dua thiab zoo nkauj dua. Kauj ruam kawg yog muab cov tshuaj pleev thaiv hnub rau hauv lub thawv tsim nyog. Muaj ntau hom thawv xaiv los ntawm, suav nrog cov xim pleev, cov tshuaj pleev, cov ntaub npog ntsej muag, thiab lub raj mis.​

Tsis tas li ntawd, txoj kev tsim khoom ntawmtshuaj pleev thaiv hnubkuj suav nrog kev siv cov khoom siv yooj yim xws li talc, roj yaj, beeswax thiab hydrolyzed whey. Talc siv los tiv thaiv lub hnub, cua sov thiab kev ua qias tuaj hauv huab cua; roj yaj muab cov dej noo thiab lubrication; beeswax muaj cov nyhuv antiseptic; hydrolyzed whey pab talc impregnate thiab rho tawm cov tshuaj. Thaum lub sijhawm tsim khoom, cov ntaub ntawv no yuav raug sib xyaw, cua sov kom txog thaum talc yaj tag, ntxiv rau hauv cov kua zaub kub rau saum cov roj kub, thiab tom qab ntawd cov khoom xyaw yaj hauv dej yuav raug ntxiv ib zaug, thiab tom qab ntawd cov roj txias yuav raug nchuav rau hauv kom sib tov thiab sib tov, thiab thaum kawg cov roj zaub thiab cov khoom xyaw kho yuav raug ntxiv thiab sib tov sib npaug.​

Kev tswj xyuas thiab kev kuaj xyuas zoo kuj tseem ceeb heev rau hauv cov txheej txheem tsim khoom. Qhov no suav nrog kev coj cov qauv los ntawm ntau qhov chaw ntawm cov kab ntau lawm thiab kuaj cov qauv raws li cov qauv thiab cov txheej txheem tau teev tseg kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm tau zoo ntawm cov tshuaj pleev thaiv hnub.
