Abstract
Granular, built laundry detergent compositions containing particular smectite clay minerals. Compositions containing such clays provide softening and/or antistatic benefits to fabrics washed therein.
Claims10
A granular, built laundry detergent composition consisting essentially of:
- a. from about 5% to about 20% by weight of a water soluble non-soap synthetic detergent compound selected from the group consisting of anionic synthetic detergents, nonionic synthetic detergents, ampholytic synthetic detergents, zwitterionics synthetic detergents, and mixtures thereof;
- b. from about 10% to about 60% by weight of an organic or inorganic detergent builder salt;
- and
- c. from about 1% to about 50% by weight of a smectite clay selected from the group consisting of sodium and calcium montmorillonites, sodium saponites, sodium hectorites, lithium and magnesium hectorites, lithium and magnesium saponites, and mixtures thereof, having a cation exchange capacity of at least about 60 meq/100g.,
- said composition providing a solution pH of from about 7 to about 12 when dissolved in water at a concentration of about 0.12% by weight.
