O le Hexadecyl dimethyl tertiary amine o se vailaʻau faʻaola mo pisinisi. O vailaʻau faʻaola mo pisinisi e faʻatatau i sauniuniga e faʻaaogaina i pisinisi e fasioti pe taofia ai le tuputupu aʻe o meaola ninii, ma e tele a latou faʻaoga. O vailaʻau faʻaola mo le Quaternary ammonium salt o se tasi o vailaʻau faʻaola mo pisinisi e sili ona faʻaaogaina, ae o vailaʻau faʻaola mo le quaternary ammonium salt o loʻo faʻaaogaina lautele i le taimi nei e masani ona laʻititi le mamafa o le molecular, e iai ni faʻamaʻi faʻaletino ma le mageso o le paʻu, ma o le a feoaʻi ma liu suavai i le taimi e faʻaaogaina ai ma faʻasaʻolotoina i le siosiomaga o loʻo siomia ai, lea e ono afaina ai meaola ma le siosiomaga.

Mea mata mo le gaosia o vailaʻau faʻapaʻepaʻe e maualuga le aoga, mea e faʻafefiloi ai vailaʻau pesticide, mea e faʻaosofia ai le tuputupu aʻe o laʻau, a-naphthaleneacetic acid, surfactants, solvents, ma isi mea faapena; mea e feaveaʻi ai le lolomiina ma le valiina ma mea e feaveaʻi ai le vevela mo alava polyvinyl chloride ma le polyester; ma le fuafuaina o le numera octane ma le numera cetane o le diesel.
