A process for detergent composition which has improved solubility or dissolution in laundering solutions, especially in solutions kept at cold temperatures (i.e., less than about 30&#xb0; C.), is disclosed. The process includes mixing in at least one high-speed, low-speed, or a moderate-speed mixer, and various combinations of such mixers, at least two materials selected from the group consisting of dry agglomerates, wet agglomerates, spray dried granules, and detergent adjunct ingredients to form particles. Optionally a conditioning apparatus may also be used. The granular detergent composition made from this process is aesthetically pleasing to consumers and has improved flowability.

Process for making a granular detergent composition

A detergent granule and tablets which comprises an anionic surfactant system which comprises an anionic sulphate surfactant and/or an anionic sulphonate surfactant and other detergent active ingredients, the granule comprising at least a first and a second particulate component and optionally a binding agent, characterised in that the ratio of anionic sulphate surfactant to anionic sulphonate surfactant in the particulate components and in the optional binding agent is less than 1:4 or more than 4:1, preferably even less than 1:5 or more than 5:1. The invention also relates to specific granules comprising restricted degree of mixing of anionic sulphonate surfactant and zeolite, anionic sulphate surfactant and carbonate salts and/or restricted degree of mixing of polymeric builder and anionic surfactant, in particular sulphate surfactants.

Detergent granules

A granular detergent composition comprising from about 0.01% to about 50% by weight of an anionic sulphonate surfactant, from about 0.01% to about 45% by weight of a hydrotrope, and from about 0.5% to about 5% by weight of a cationic surfactant. The granular detergent composition is substantially free from anionic sulphate surfactant.

Granular detergent composition having an improved solubility

Granular detergent compositions are prepared by an agglomeration process and impregnated with a water-insoluble disintegrant to improve water solubility. Laundry detergent compositions are described.
