Sodium lauryl sulfate (SLS) yog surfactant feem ntau siv.

YPuas yog tshuaj txhuam hniav puas yog surfactant?

Surfactants. Ntau, txawm tias tsis yog tag nrho, tshuaj txhuam hniav muaj sodium lauryl sulfate (SLS) lossis lwm yam surfactants (detergents). SLS muaj nyob rau hauv ntau lwm yam khoom siv tu tus kheej ib yam nkaus, xws li tshuaj zawv plaub hau, thiab feem ntau yog ib tus neeg ua npuas ncauj, uas ua rau cov tshuaj txhuam hniav sib xws, txhim kho nws lub zog ntxuav.

Cov khoom tseem ceeb hauv cov tshuaj txhuam hniav yog dab tsi?

Fluoride . Fluoride yog cov khoom tseem ceeb ntawm cov kab noj hniav hauv cov tshuaj txhuam hniav, uas pab txhawb cov enamel thiab tiv thaiv cov hniav lwj. Txhua lub raj ntawm cov tshuaj txhuam hniav nrog ADA foob muaj fluoride.

Yuav siv tshuaj dab tsi hauv tshuaj txhuam hniav?

tshuaj txhuam hniav feem ntau muaj cov khoom nram qab no: Dej (20–40%) Abrasives (50%) suav nrog txhuas hydroxide, calcium hydrogen phosphates, calcium carbonate, silica thiab hydroxyapatite. Fluoride (feem ntau yog 1450 ppm) feem ntau nyob rau hauv daim ntawv ntawm sodium fluoride.

Puas dentifrices muaj surfactant?

Cov khoom siv feem ntau yog sodium lauryl sulphate, sodium N-lauroyl sarcosinate thiab sodium methyl cocoyl taurate, thiab feem ntau yog siv ntawm 1-3% w / w. Qhov tsw yog qhov tseem ceeb hauv kev txiav txim siab qhov kev xav ntawm lub dentifrice thiab feem ntau yogntxiv ntawm kwv yees li 1% w/w.
