Nrog rau kev nce qib ntawm lub zej zog thiab kev txhim kho ntawm tib neeg lub neej, tib neeg them sai sai rau kev saib xyuas lawv cov tawv nqaij thiab lawv tus kheej lub duab. Kev xaiv cov tshuaj pleev ib ce tsis txwv rau cov khoom siv niaj hnub xws li tshuaj pleev ib ce, tshuaj pleev ib ce, thiab tshuaj pleev ib ce, thiab qhov kev thov rau cov khoom siv pleev ib ce xim tab tom loj hlob. Cov tshuaj pleev ib ce xim tuaj yeem txhim kho thiab ua kom zoo nkauj rau tus kheej daim tawv nqaij thiab qhov zoo li sai tau. Txawm li cas los xij, titanium dioxide, mica, cov neeg sawv cev ua zaj duab xis, toners thiab lwm yam khoom siv raw hauv cov khoom siv pleev ib ce xim tsis raug nqus los ntawm daim tawv nqaij. Ua rau lub nra hnyav rau ntawm daim tawv nqaij, ua rau muaj teeb meem xws li daim tawv nqaij ntxhib, qhov loj ntawm cov qhov hws, pob txuv, pigmentation, daim tawv nqaij tsis zoo, thiab lwm yam, cuam tshuam rau kev noj qab haus huv thiab qhov zoo li ntawm daim tawv nqaij.

Muaj ntau hom tshuaj pleev kom tsis txhob pleev xim sib txawv hauv khw, xws li dej pleev kom tsis txhob pleev xim, mis pleev kom tsis txhob pleev xim, roj pleev kom tsis txhob pleev xim, ntaub so pleev kom tsis txhob pleev xim, thiab lwm yam, thiab kev ua haujlwm ntawm ntau hom tshuaj pleev kom tsis txhob pleev xim sib txawv, thiab cov teebmeem ntxuav ntawm cov tshuaj pleev xim kuj sib txawv.
Raws li tus sau ntawv tau ntau xyoo ntawm kev tshawb fawb thiab kev txhim kho, tsab xov xwm no qhia txog cov mis, lub hauv paus ntsiab lus ntawm cov mis thiab cov txheej txheem tsim cov tshuaj tshem tawm pleev.
Cov roj 50-60%, cov roj siv feem ntau yog isoparaffin solvent oil, hydrogenated polyisobutylene, triglyceride, isopropyl myristate, ethyl oleate, ethylhexyl palmitate, thiab lwm yam. Cov roj hauv cov mis no tuaj yeem yaj cov khoom siv organic uas yaj tau hauv cov khoom pleev seem, thiab muaj cov txiaj ntsig zoo rau kev noo noo thiab noj qab haus huv kom tsis txhob muaj tawv nqaij qhuav tom qab tshem tawm pleev.
Cov tshuaj surfactant 5-15%, feem ntau siv cov surfactants yog anionic thiab nonionic surfactants, xws li polyglycerol oleate, polyglycerol stearate, polyglycerol laurate, PEG-20 glycerin Triisostearate, PEG-7 Glyceryl Cocoate, Sodium Glutamate Stearate, Sodium Cocoyl Taurine, Tween, Span, thiab lwm yam. Cov tshuaj surfactants tuaj yeem emulsify cov roj-soluble organic raw cov ntaub ntawv thiab cov hmoov inorganic raw cov ntaub ntawv hauv cov khoom siv pleev xim seem zoo. Nws kuj ua haujlwm ua emulsifier rau cov roj thiab cov rog hauv cov tshuaj pleev kom zoo nkauj.
Polyol 10-20%, cov polyols uas siv feem ntau yog sorbitol, polypropylene glycol, polyethylene glycol, ethylene glycol, glycerin, thiab lwm yam. Tsim los ua ib qho humectant.
Cov khoom ua kom tuab 0.5-1%, feem ntau siv cov khoom ua kom tuab yogcarbomer, acrylic acid (ester)/C1030 alkanol acrylate cross-linked polymer, ammonium acryloyl dimethyl taurate/VP copolymer, acrylic acid hydroxyl Ethyl ester/sodium acryloyldimethyltaurate copolymer, sodium acrylic acid (ester) copolymer thiab sodium polyacrylate.
Txheej Txheem Tsim Khoom:
Kauj Ruam 1: cua sov thiab do dej, dej-soluble surfactant thiab polyol humectant kom tau txais cov dej theem;
Kauj Ruam 2: Sib tov cov roj emulsifier nrog cov roj los tsim cov roj theem;
Kauj Ruam 3: Ntxiv cov roj theem rau hauv cov dej theem kom sib xyaw ua ke thiab kho tus nqi pH.
