1,5-Pentanediol is the organic compound with the formula HOCH2CH2CH2CH2CH2OH. Like other diols, this viscous liquid is used as plasticizer and also forms polyesters that are used as emulsifying agents and resin intermediates. It is manufactured by hydrogenation of glutaric acid and its derivatives.
Contamination of Bindeez
- See also: 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. 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 per metric ton, while the price for 1,5-pentanediol is about US$9,700 per metric ton.
