Sodium metasilicate pentahydrate o malosi alkaline, i le tulaga malosi o le faamamaina, buffering ma agamalu, counteracting faaleagaina acidic, emulsifying gaʻo ma le suauu, deflocculating e inorganic. E mafai ona suia STPP e faaaoga mo le gaosia o detergents lelei ma remover ele mo uamea, le faaitiitia o aafiaga filogia o le siosiomaga, e taofia corrosion mo uamea (metala paʻepaʻe, alumini, ma isi). O le mea lea, sodium metasilicate pentahydrate o loo faaaogaina faalauaitele mo le gaosia o le a eseese detergents, faaaogaina o ele remover mo uamea, olo fesoasoani mo ceramics, deinking sooupu mo pepa, dyeing ma le lolomiina o ausilali mo le aveesea o le suauu i alamanuia lavalava, ma faaaogaina foi e pei o le mea e masani ona maua mo flameproofing sooupu, palasitika sooupu tausiga, vai sooupu faatumauina, ma isi Faaaogaina i le vai faaitiitia sui, sodium metasilicate pentahydrate e mafai ona tuufaatasi hydrones tele atu ai ona lelei susu aafiaga mitiia
