(1)Polycarboxylate ʻO ka mea hoʻemi wai ka nui o nā meaʻai no ke ola ʻana o ka bacteria a me nā microorganism ʻē aʻe. ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka maʻalahi o nā microorganism e hana hou, a ʻoi aku ka wikiwiki o nā mea pono i lokopolycarboxylate pau ka mea hoemi wai. I ka loaʻa ʻole o nā preservatives, ke ʻoi aku ka mahana o ka ambient ma mua o 25℃a mālama ʻia no nā lā 7, a i ka wā e pili ana ka mahana ambient ma kahi o 10℃a mālama ʻia no nā lā 28, aia ka maʻi bacteria ma ka pae o 10cfu/ml. I kēia manawa, nui ka pohō o ka pahu i ka manawa a me kahi manawa hoʻonohonoho pōkole.

(2) ʻO nā preservatives ʻoihana a i ʻole sodium metabisulfite i ka mākeke he hopena bactericidal a me antiseptic maikaʻi, a me 1‰hoʻohui ʻia. ʻO ka maʻi bacteria o ka mea hoʻemi wai me nā preservatives he <10cfu/ml ma hope o ka mālama ʻia ʻana ma 9-15℃no 28 mau lā, a hoʻohui ʻia he 5%. ʻO ka maʻi bacteria o ka mea hoʻemi wai me ka sodium metabisulfite he 10-100cfu / ml ma hope o ka mālama ʻana ma 9-15℃no 28 lā. Loaʻa ka poho maʻamau o ke koʻi i ka manawa a me ka manawa hoʻonohonoho. No laila, i mea e pale aku ai i kapolycarboxylate ʻO ka hoʻemi ʻana i ka wai mai ka pōʻino i ka wā e mālama ai, ʻo ka hoʻohui ʻana i nā preservatives kahi ala kūpono.

(3)E like me ka ho'āʻo antiseptic ho'āʻo opolycarboxylate ka mea hoʻemi wai, inā he 2% ka hoʻohui ʻana o nā mea mālama ʻelua, ʻo ka maʻi bacteria i ka wā o ka hoʻāʻo hoʻāʻo antiseptic holoʻokoʻa he <10cfu/ml; i ka wā i hoʻohui ʻia ai ka nui o ka preservative he 1‰, ka helu bacteria o kapolycarboxylate ʻO ka mea hoʻemi wai me ka hoʻohui o ka preservative E16 i hoʻomaka e hoʻonui ma hope o 21 mau lā, a me ka helu bacteria o kapolycarboxylate ʻO ka mea hoʻemi wai me ka hoʻohui o ka preservative 02F hoʻomaka e hoʻonui ma hope o 7 mau lā, e hōʻike ana he ʻokoʻa nā mana bactericidal a me antiseptic o nā preservatives like ʻole. No laila, pono e hoʻoholo ʻia ke ʻano maoli a me ka nui o nā preservatives i hoʻohui ʻia ma o nā hoʻokolohua e pili ana i nā kūlana mālama a me ka lōʻihi.
