Contamination of Bindeez

A toy called '' Bindeez'' (''Aqua Dots'' in North America) was recalled by the distributor in November 2007 because of the unauthorized substitution of 1,5-pentanediol with

1,4-butanediol 1,4-Butanediol, colloquially known as BD or BDO, is a primary alcohol, and an organic compound, with the formula HOCH2CH2CH2CH2OH. It is a colorless viscous liquid. It is one of four stable isomers of butanediol. Synthesis In industrial synthe ...

. The toy consists of small beads that stick to each other upon sprinkling 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 about US$1,350–2,800/tonne, while the price for 1,5-pentanediol is about US$9,700/tonne.
