1. A particulate detergent composition comprising:
(i) sulphonated fluorescer (ii) greater than 40 wt % detergent surfactant, and (iii) water soluble inorganic salt wherein at least 70% of a total number of particles in the particulate detergent composition consist of:
(a) a core consisting of the surfactant and optionally, at least one of perfume, enzyme, enzyme stabilizer, cleaning polymer, soil release polymer, water, carboxymethylcellulose, polyethylene glycol, polyvinyl alcohol, polyethylene imine, ethoxylated polyethylene imine, water soluble polyester polymer, polycarboxylate, polyacrylate, maleic/acrylic acid copolymer, or lauryl methacrylate/acrylic acid copolymer, and(b) a coating consisting of the water soluble inorganic salt andthe sulphonated fluorescer, and optionally, at least one of perfume, enzyme, enzyme stabilizer, water, carboxymethylcellulose, polyethylene glycol, polyvinyl alcohol, polyethylene imine, ethoxylated polyethylene imine, water soluble polyester polymer, polycarboxylate, polyacrylate, maleic/acrylic acid copolymer, or lauryl methacrylate/acrylic acid copolymer;wherein the coating is positioned around the core, and wherein each particle has perpendicular dimensions x, y and z, and wherein x is from 0.2 to 2 mm, y is from 2.5 to 8 mm, and z is from 2.5 to 8 mm. |
