The present invention relates to a colored particles and to detergent compositions containing them that can be used to impart a hueing effect to fabrics contacted with these colored particles in aqueous solution. The invention enables the effective hueing while alleviating problems of staining or spotting by combining in the color particle, hueing agent, preferably pigment, binding agent and suspending agent.

Detergent compositions comprising coloured particles

A process for forming a low density detergent granule has the steps of providing from about 0.1% to about 6% of a hydrotrope, providing from about 22% to about 50% crutcher mix moisture, providing from about 0.2% to about 8% of a water-soluble polymer with a molecular weight of at least about 10,000 g/mol, providing from about 2% to about 20% sodium silicate having a SiO:NaO ratio of at least about 2:1, and the balance of adjunct crutcher ingredients, mixing the hydrotrope, crutcher mix moisture, polymer, silicate, and adjunct crutcher ingredients in a crutcher to form a slurry, injecting a gas into the slurry at a pressure of from about 6,000 kPa to about 13,000 kPa, and at a rate of from about 0.01% to about 0.25% and forming the slurry into a detergent granule. The slurry is substantially free of zeolite builder and phosphate builder and the crutcher temperature is maintained at from about 40&#xb0; C. to about 95&#xb0; C.

Antimicrobial detergent compositions especially suitable for manual diswashing comprise 0.001-2% iodine ions complexed with an amphoteric surfactant, 5-90% uncomplexed surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, amphoteric surfactants and mixture thereof, and 5-50% water. The detergent compositions have pH of 7-10. Preferably at least a portion of the iodine ions are added as an iodine in the form of a compound selected from the group consisting of KI, NaI, KOI, NaOI and Ca(0I)2.
