AN1119: Determination of Trace Amounts of Boric Acid in Cosmetics
Description
Boric acid and borates (e.g., metaborate, borate, and tetraborate) are added to some cosmetics as a preservative and antibacterial agent. But once inhaled or absorbed through skin cuts, boric acid and borates can cause intoxication. An IC method that has been applied to the sensitive determination of borate (boric acid) in water samples is applied to the determination of borate in cosmetics. Borate is separated using 3 mM MSA 60 mM mannitol eluent on a Dionex ICE-borate column and detected by suppressed conductivity using external chemical regenerant.| Market: | Electronics & Semiconductors; Pharma |
