Expert Verdict

Contains beryllium as structural component in crystalline beryl form with extremely low water solubility, limiting bioavailability. Respirable beryllium is a known carcinogen and sensitizer (IARC Group 1); inhalation risk exists during manufacturing and in loose-powder formats, but not in finished product consumer use. Particle size control is critical to avoid pulmonary exposure.
