The invention relates to detergent compositions comprising from 10-60 wt % of a surfactant system and having a maximum Residues Index of 25 and a maximum Secondary Residues Index of 15. The detergents claim provide good performance in the wash based on the quantities of detergent components in the compositions.

Solid detergent compositions containing mixtures of surfactant/builder particles

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 convenient process for making builder material which has substantially improved performance and is significantly less expensive than previous builders is provided. The builder material has improved performance in that it unexpectedly has a high calcium ion exchange capacity and rate, and is easy to handle, process and disperse in washing solutions. In its broadest aspect, the invention is directed to a process involving converting starting materials (via any means including but not limited to heating and precipitating) to a builder material having at least one crystalline microstructure including a carbonate anion, calcium cation and at least one water-soluble cation. The microstructure should have a sufficient number of anions and cations so as to be 'balanced' or 'neutral' in charge.
