Abstract
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.
Claims7
A solid detergent composition comprising from 10 to 60 wt % of a surfactant system and having a maximum Residues Index of 25 and a maximum Secondary Residues Index of 15, said composition comprising:
- (a) from 3% to 50% by weight of the composition of first particles comprising from 25% to 75% by weight of the particles of a partially water-soluble crystalline layered silicate builder and from 25% to 75% by weight of the particles of an alkyl benzene sulphonate surfactant, said partially water-soluble builder and said surfactant being intimately mixed;
- (b) second particles comprising a water-soluble builder, said particles being present in an amount sufficient to provide from 1% to about 80% by weight of the composition of a water-soluble builder, said water-soluble builder being intimately mixed with a surfactant;
- and
- (c) the balance of the composition comprising a member selected from the group consisting of zeolites, bleaches, chelants, alkalinity sources, organic polymeric compounds, enzymes, brighteners, suds suppressors, lime soap dispersants, soil suspension agents, anti-redeposition agents and corrosion inhibitors, with the proviso that if zeolites are present they comprise less than 4% by weight of the composition.
