Calcium formate riantuannak cu a bik in pawpi pawngkam ah a tthenmi formic acid thawngin a si, cun a tthatnak cu potassium diformate he aa lo:
Pawpi chung i pH man kha a niamter, cu nih cun pepsin kha a cawlcangter, vok note hna paw chung i rawl ei khawhnak enzyme le hydrochloric acid a tlawm tukmi kha a tlawmter, cun rawl rawl ei khawhnak a tthanter. Escherichia coli le a dang zawtnak a chuahter khomi bacteria ṭhanchonak le hrinnak kha a kham, cu lioah ṭhatnak a chuahtermi bacteria (lactic acid bacteria tibantuk) ṭhanchonak kha a bawmh. Hi tthatnak a chuahtertu bacteria nih hin pawpi chung vun kha a khuh, Escherichia coli nih a chuahtermi rungrul nih a luhhnawh khawh lonak hnga a kham, cucaah bacteria zawtnak he aa pehtlaimi zunthlum a zorter.
Organic acid pakhat a si bantukin, formic acid cu rawl ei lio ah chelating agent rian a ttuan, cu nih cun pawpi nih minerals a lak khawhnak a tthanter.

Maleic anhydride (MA) nih a phunphun in thlen khawhnak + a fekmi, a ttha ngaimi chuah khawhnak a ngeih—resin, plastic le hriak caah a ttha. Na thil sernak caah zeitindah man a tlawmter ti na hngal maw? Biaruahnak caah hmet!
