Claims
- 1. A liquid detergent composition comprising an internal active-structured phase containing detergent active material, dispersed in an aqueous phase containing dissolved electrolyte, and 0.5 to 4.5% by weight of a viscosity reducing polymer, the electrolyte containing aqueous phase being such that the polymer is dissolved therein at a level 8% to 49% by weight and the composition having a pH of 8.0 or above said composition further comprises a suspended solid particulate material selected from the group consisting solely of builders, abrasives, and bleaches and further comprising a second polymer which is different from the viscosity reducing polymer in an amount of 0.05 to 20% of the composition and having a molecular weight of 1,200 to 30,000.
- 2. A composition according to claim 1, which yields less than 2% phase separation upon storage at 25.degree. C. for 21 days.
- 3. A composition according to claim 1, which has a viscosity no greater than 1 Pas at a shear rate of 21s.sup.-1.
- 4. A composition according to claim 1, wherein the viscosity reducing polymer is a co-polymer which includes an alkali metal salt of a polyacrylic, polymethacrylic or maleic acid or anhydride.
- 5. A composition according to claim 1, comprising from 1 to 3.5% by weight of the viscosity reducing polymer.
- 6. A composition according to claim 1, wherein the second polymer has an average molecular weight of at least 2,000.
- 7. A composition according to claim 1, wherein the second polymer has an average molecular weight of from 5,000 to 30,000.
- 8. A composition according to claim 1, in which the detergent active material comprises:
- a) a nonionic surfactant, a polyalkoxylated anionic surfactant and mixtures thereof; and
- b) a non-polyalkoxylated anionic surfactant.
- 9. A composition according to claim 1, in which the electrolyte is present from 1 to 60% by weight of the total composition.
- 10. A composition according to claim 1, wherein the viscosity reducing polymer has builder properties.
- 11. A composition according to claim 1, in which the suspended solid particulate material comprises a water-insoluble aluminosilicate salt.
- 12. A composition according to claim 1, wherein the suspended particulate material comprises a substantially water-insoluble bleach.
- 13. A composition according to claim 1, wherein the bleach comprises disperoxydodecanediaic acid.
