摘要

The present invention provides lenticular or disc detergent particles comprising surfactant, inorganic salts and pigment, wherein the inorganic salts are present on the detergent particles as a coating and the surfactant and the pigment are present as a core. The particles show reduced staining.

主权项

1. A coated detergent particle having perpendicular dimensions x, y and z, wherein x is from 0.5 to 2 mm, y is from 2 to 8mm, and z is from 2 to 8 mm, wherein the particle comprises:
(i) from 20 to 39 wt % of a surfactant selected from: anionic and non-ionic surfactants; (ii) from 10 to 40 wt % of inorganic salts selected from: sodium carbonate and/or sodium sulphate of which at least 5 wt % of the inorganic salt is sodium carbonate; and, (iii) from 0.0001 to 0.1 wt % pigment, wherein the pigment is selected: from organic and inorganic pigments, and wherein the inorganic salts are present on the detergent particle as a coating and the surfactant and the pigment are present as a core.
