LAUNDRY DETERGENT PARTICLES |
摘要 |
The present invention provides 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 8 mm, 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 an inorganic salt coating selected from: sodium carbonate and/or sodium sulphate of which at least 5 wt % of the inorganic salt is sodium carbonate; and, (iii) from 10 to 40 wt % of calcite having a median particle size average diameter (D50) in the range from 10 to 70 microns, and wherein the inorganic salts and are present on the detergent particle as a coating and the surfactant is present a core with the calcite dispersed though the core. |
