Sodium tripolyphosphate nke a makwaara dị ka pentasodium phosphate, sodium pyrometaphosphate, STPP, pentasodium tripolyphosphate. kristal na-acha ọcha nke nwere mmiri dị mma, ịdị arọ molekụla ikwu nke 367.Chemicalbook86, ebe agbaze nke 622 ℃, na-agbaze ngwa ngwa n'ime mmiri, ihe ngwọta ya bụ alkaline. A na-ejikarị na nri dị ka ihe na-ejigide mmiri, onye na-emeziwanye mma, onye na-ahụ maka pH, na onye na-ahụ maka chelating metal.

Sodium tripolyphosphate aqueous ngwọta bụ alkaline na-adịghị ike (ọnụahịa pH nke 1% ngwọta mmiri dị ihe dị ka 9.7), ọ na-emepụta nkwusioru (dị ka emulsion) na mmiri nke nwere pH nke 4.3-14, nke a na-akpọ mgbasa. Sodium tripolyphosphate nwekwara ike melite solubility nke mmiri mmiri na ihe siri ike kemịkalụ ahụ na mgbasa ozi mmiri (dị ka mmiri), na-eme ka ngwọta ahụ pụta ìhè kpamkpam ma yie ezigbo ngwọta.
