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 Nov. 9, 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”, said Andrew Jackson, global product manager Optical Brightening Agents, Paper Solutions Business, Archroma. “Complementing our FDA-compliant tetrasulphonated OBAs and shading colorants, Leucophor AFCN liquid provides our customers with greater flexibility to produce attractive, white, paper-based packaging and containers for food applications.
