Abstract
The present invention relates to a novel presentation of a phenolic compound in the solid form. More particularly, the invention provides beads of hydroquinone. The invention also pertains to the preparation of said beads. The process of the invention is characterized in that a hot concentrated aqueous solution of a phenolic compound is prepared, then the solution is fragmented into droplets and the droplets obtained are cooled in a gas stream so that they solidify into beads which are then recovered and dried.
