Tom qab ntawv muab li cas? Cov khoom uas nyob hauv no muab tso rau ntawm cov protein nyob rau hauv qhov hlau yaj, thaum cov chaw uas tsis muaj nyuj yuam yog ib qho cuab yeej tiv thaiv. Ib txoj ceev lawv pab tiv thaiv qhov hlau yaj kom meej meej thiab tiv thaiv nws kom tsis txhob kub thiab poob, tsis txhob muab cov kab ntsig leeg leeg uas peb xav tau rau kev sib txuas hluas hluas. Ib qho tshiab dua ntawm cov khoom no siv technology nano, muab cov khoom siv tau nyob rau qhov loj li 20 mus rau 50 nanometers. Qhov no txhais tau tias nkag siab ntau dua tsis muaj kev txwv, ib qho uas ntau tus neeg tsim kho hlau yaj tau hais tawm ntau heev txog kev pab ua zoo dua qhov siv cov formula cuas uas tsuas yog nyob saum npoo tsis yog nyob qhov chaw xav tau.

Cov khoom nyob hauv cov kem hlau yaj uas muaj peev xwm

Cov txheej nkauj tshaj plaws uas siv rau ntaub hniav feem ntau muaj cov khoom tsim los ntawm dej nkauj tshuab, uas zoo heev rau kev txhawb kom ntaub hniav nyuaj siab vim nws muaj oleic acid, thiab cacao butter uas muaj cov antioxidants zoo tshaj plaws uas neeg feem ntau hais txog nyob no. Lanolin pab tau qhov zoo tshaj yog li nws zoo ib yam li cov dej nkauj tshuab uas nyob ze ntaub hniav nyob thaum ua ntej, thaum li ntawd beeswax pab tiv thaiv kom tsis txhob tuag. Lub kaw lus pub tej nqe lus tshiab hais tias: thaum cov txheej muaj emollients tshaj li 8%, lawv tsim kev pab tau zoo dua cov txheej tshaib txaus 37% hauv kev test elasticity. Txhawm rau saib xyuas cov yam ntxwv tseem ceeb, ntau yam khoom muaj cov khoom siv silicone.
