Archroma introduced a new optical brightening agent (OBA) specially designed for food packaging and paper – Leucophor AFCN liq – which was approved for food contact by the U.S. Food and Drug Administration (FDA).

Leucophor® AFCN liq was designed with these guiding principles in mind:

  • Leucophor® AFCN liquid has approval for use in food-contact paper and paperboard under FDA Food Contact Notification 1921, which became effective on 9 November 2018.
  • Leucophor® AFCN liq is ideally suited for stock application and for use in coating formulations that contain polyvinyl alcohol (PVOH), carboxymethyl cellulose (CMC) or casein as a secondary binder.
  • Leucophor® AFCN liq is a disulphonated OBA, with a characteristically high substantivity in the wet-end delivering the papermaker cost savings through the ability to make more rapid grade changes.

“There is a fast-growing demand for food packaging made with paper and board, and our Leucophor® AFCN liquid OBA has been developed to help manufacturers to respond to that demand”, comments Andrew Jackson, Global Product Manager Optical Brightening Agents, Paper Solutions Business, Archroma.
