Abstract (en)
[origin: EP3318622A1] Coloured particles for detergents and the process for obtaining them, that is the subject matter of this invention, comprising coloured particles of bentonite for detergents, preferably of a light colour or white, as the binding agent, sodium sulfate, water as the binder and pigment or liquid dye as the colouring agent and employing a characteristic production process, which comprises a phase of mixing the solids, a phase of metering the water and/or additives and a granulating phase. The product presented affords the advantages being faster-dissolving, having a better apparent density, a better colouring quality and a lower cost. Its production process simplifies the equipment to be used and reduces the number of phases, resulting in a more efficient process and a product of greater quality and better characteristics.
