On 7 March 2016, The National Institute of Metrology, Quality and Technology (INMETRO) published amendment of the Technical Regulation on Safety for Toys, to prohibit the certification and sales of AquaDots, Bindeez and other similar toys (referred to the throughout as the "Covered Toys") containing the chemical substance 1,4butanediol (also called 1,4butylene glycol). Manufacturer and suppliers should immediately withdraw such toys from the Brazil market.
The Covered Toys if not containing 1,4-butanediol would be allowed to be certified and marketed in Brazil with a clear warning that they are not intended for children younger than three years of age. To obtain the required certification, Manufacturer or supplier should submit the Covered Toys, declaration letter and technical report (with analytical test method indicated) to a certification body to demonstrate 1,4-butanediol is not present.
1,4-butanediol is used as adhesive solvent on the small colourful beads or dots. When sprayed with water, they can be fixed into shapes. The substance can become toxic after stimulation. Children who swallow the beads will suffer from unconsciousness; respiratory depression, or even seizures.
