A toy called
Bindeez (
Aqua Dots in North America) was recalled by the distributor in November 2007 due to the unauthorized substitution of 1,5-pentanediol with
1,4-butanediol. The toy consists of small beads that stick to each other when sprinkled with water. 1,4-Butanediol, which when ingested is metabolized to
gamma-hydroxybutyric acid, was detected by
GC-MS. ChemNet China lists the price of 1,4-butanediol at between US$1,350–2,800/tonne, while the price for 1,5-pentanediol is about US$9,700/tonne. ==References==
