Abstract
The present invention relates to a laundry detergent composition comprising a particle comprising hueing agent and clay. The particle can be incorporated into laundry detergent products, such as a laundry detergent powder. The particle exhibits an excellent storage stability profile with very little bleeding of the hueing dye from the particle, exhibits excellent fabric deposition of the hueing dye during a laundering process without causing any spot staining of the fabric, and does not impact the visual appearance of a laundry detergent powder when incorporated therein.
