Abstract (en)

Procedure for colouring granulated non-adsorbent minerals and the product thus obtained, of the type used in the field of chemical products and processes leading to coloured specks being obtained which are used in the detergent industry, characterised in that it allows coloured non-adsorbent minerals of a diameter between 300 and 2,000 µm to be obtained from a granular base of that same size, a binding agent and a colouring agent or pigment, used in the detergent industry as "speckles", an English term which defines the multi-coloured specks present in powdered detergent. The invention presented contributes the main advantage of allowing coloured, non-adsorbent minerals to be used with a reproducible method in stable production, all at a significantly lower economic and environmental cost.
