Warning

Texas Senate Bill 25 (89th Legislature, 2025) lists this substance among 44 ingredients that trigger a mandatory consumer warning label under Texas Health & Safety Code Sec. 431.0815. The label reads: "WARNING: This product contains an ingredient that is not recommended for human consumption by the appropriate authority in Australia, Canada, the European Union, or the United Kingdom." It applies to food labels developed or copyrighted on or after January 1, 2027. On February 11, 2026 the U.S. District Court for the Western District of Texas preliminarily enjoined enforcement against the plaintiff trade groups and their members; Texas appealed to the Fifth Circuit on March 5, 2026.
