Claims
- 1. A bleaching granule for incorporation into a detergent composition comprising no more than 50 wt % of a particulate bleach component selected from bleach activators, bleach catalysts and mixtures thereof, and in addition, surfactant and/or builder and optional detergent ingredients and/or fillers the geometric mean particle diameter of the particulate bleach component being below 500 μm.
- 2. A bleaching granule according to claim 1 comprising no more than 30 wt % of a particulate bleach component.
- 3. A bleaching granule according to claim 1 in which the geometric mean particle diameter of the particulate bleach component is below 200 μm.
- 4. A bleaching granule according to claim 1 having a geometric mean particle diameter of from 200 μm to 2500 μm.
- 5. A bleaching granule according to claim 1 in which the bleach component comprises bleach activator and/or bleach catalyst either in solid form or on a solid carrier.
- 6. A bleaching granule according to claim 1 in which the bleach component comprises bleach activator.
- 7. A bleaching granule according to claim 1 in which the bleach activator is tetracetyl ethylene diamine (TAED).
- 8. A bleaching granule according to claim 1 comprising at least 15 wt % builder selected from aluminosilicates (zeolites), crystalline layered silicates and carboxylates.
- 9. A bleaching granule according to claim 1 comprising at least 5 wt % surfactant selected from anionic surfactants and nonionic surfactants or mixtures thereof.
- 10. A bleaching granule according to claim 1 which comprises both builder and surfactant which are present in the bleaching granule as a pre-formed particulate.
- 11. A detergent composition comprising a bleaching granule according to claim 1.
- 12. A method for making a bleaching granule according to claim 1 in which in a mixing step the particulate bleach component is mixed with builders and/or surfactants and optionally other detergent ingredients and/or fillers in a high, moderate or low shear mixer.
- 13. A method according to claim 12 in which the mixing step takes place in a moderate to low shear mixer.
