Abstract
A granular detergent composition having a bulk density of at least 650 g/l and comprising at least 5% by weight of anionic surfactants, nonionic surfactants, or mixtures thereof, and further comprising: i) from 2% to 50% by weight of granular alkalimetal percarbonate, ii) from 0.7% to 20% by weight of powdered silicate, and wherein silicate particles having a particle size diameter of less than 425 micrometers comprise at least 0.7% by weight of the composition.
Claims18
A granular detergent composition having a bulk density of at least 650 g/l and comprising at least 5% by weight of anionic surfactants, nonionic surfactants, or mixtures thereof, and further comprising:
- i) from 2% to 50% by weight of granular alkali metal percarbonate having a particle size range of from 100 micrometers to 1500 micrometers;
- and
- ii) from 0.7% to 20% by weight of an amorphous sodium silicate having an SiO.sub.2 :Na.sub.2 O molar ratio of less than 3.3:1 said amorphous sodium silicate being in powdered form;
- wherein sodium silicate particles having a particle size diameter of less than 425 micrometers comprise at least 0.7% by weight of the composition.
A granular detergent composition comprising:
- i) from 2% to 50%, by weight of the composition, crystalline alkali metal percarbonate having a particle size range of from 100 micrometers to 1500 micrometers;
- and
- ii) from 1% to 20%, by weight of the composition, powdered amorphous sodium silicates having a SiO.sub.2 :Na.sub.2 O ratio of less than 3.3:1;
