Nanophase Technologies Corporation – FDA 483, Jan 9, 2026

An FDA inspection of Solesence, Inc. in Romeoville, IL, an API manufacturer, revealed that processes for the production of Active Pharmaceutical Ingredients were not followed in writing.

These issues indicate a lack of adherence to established manufacturing procedures.
