Most marketed superabsorbent polymer-made beads are cross-linked sodium polyacrylate. After ingestion of these beads, no systemic toxicity is expected, and no case of toxicity has been reported with exposure by the oral route in both humans and animals [4–9]. However, given the ability of these beads to swell in contact with a water-containing liquid, mechanical complications are to be expected, and cases of bowel obstruction following ingestion of these products have been reported [2,10]. Some superabsorbent polymer-made toys were withdrawn from the market in the United States in 2013. Then, the Australian Competition and Consumer Commission recommended that these beads should no longer be marketed as toys, and they launched an alert campaign on their risks in 2015 [11,12].
