Cov khoom xyaw tseem ceeb ntawm cov neeg ua npuas ncauj yog cov surfactants, uas ua haujlwm los ntawm kev txo qis qhov nro ntawm cov kua, yog li ua kom cov pa ua npuas hauv nws. Feem ntau siv surfactant raw khoom muaj xws li anionic hom-xws li sodium lauryl sulfate (SLS) thiab sodium lauryl ether sulfate (SLES); cationic hom-xws li quaternary ammonium ntsev; tsis yog- hom ionic- xws li fatty alcohol ethoxylates (LAE) thiab fatty acid glycerides; thiab zwitterionic hom- xws li amino acid derivatives. Cov ntaub ntawv nyoos no txiav txim siab tus neeg sawv cev foaming lub peev xwm ua npuas dej thiab ua npuas ncauj ruaj khov, thaum tseem cuam tshuam rau nws cov ntsiab lus tshwj xeeb ntawm daim ntawv thov- xws li hauv cov khoom noj, tshuaj ntxuav, lossis tshuaj pleev ib ce.
Txhawm rau txhim kho cov npuas ntim thiab lub neej ntev, cov neeg ua haujlwm pabcuam foaming feem ntau yog muab tso rau hauv cov qauv. Cov khoom xyaw no suav nrog cov proteins ntuj (piv txwv li, whey protein, ovalbumin), polysaccharides (piv txwv li, xanthan gum, guar gum), glycerol, thiab sucrose derivatives. Los ntawm kev ua kom cov kua dej viscosity thiab hloov cov khoom ntawm cov pa roj -kua interface, cov auxiliary agents no tsim cov qauv ua npuas ncauj uas tsis tshua muaj kev tawg; lawv yog tshwj xeeb yog dav siv nyob rau hauv cov khoom noj thiab tshuaj pleev ib ce industries.
Ntxiv rau cov surfactants thiab auxiliary foaming agents, formulations feem ntau muaj stabilizers los yog thickeners tsim los tswj cov txheej txheem kev ncaj ncees ntawm cov npuas dej. Cov khoom xyaw hauv pawg no suav nrog sodium carboxymethyl cellulose, xanthan gum, thiab carbomers; Cov tshuaj no ua rau kom cov kua viscosity thiab retard lub coalescence thiab rupture ntawm npuas, yog li ncua lub npuas lub lifespan. Nyob ntawm daim ntawv thov tshwj xeeb, fragrances, colorants, los yog preservatives kuj yuav muab ntxiv los xyuas kom meej tias cov foaming agent muaj ob qho tib si zoo nkauj thiab kev nyab xeeb thaum siv.
