Estimating the term…
The invention provides liquid hard surface cleaning compositions comprising multiple partial compositions held separately from each other in a multiple compartment container which is provided with a non-spray dispensing system. One partial composition comprises a peroxygen bleach compound, preferaqbly hydrogen peroxide. The total composition comprises a multi-component thickening system of which the components are divided over the partial compositions in such a way that the total composition thickens on dispensing. Each partial composition has a pH at which the components in it are stable, while after mixting the total composition has a pH suitable for cleaning. The compositions preferably contain a quaternary imine salt bleach activator and a detergent surfactant. The number of partial compositions and of the compartments in the container is preferably 2.
A multi-part thickenable non-spray dispensible liquid cleaning composition comprising at least two liquid partial compositions each having a viscosity of 20 mPa·s or less and which are held separate from each other in a single container comprising at least two chambers and which at least two liquid partial compositions are delivered using a non-spray dispensing system, wherein at least one partial composition comprises a peroxygen bleach compound and wherein the cleaning composition comprises a multicomponent thickening system of which the components are divided over at least two partial compositions, such that on mixing of the partial compositions the combination of the components of the thickening system causes the final composition to thicken, said final composition having a viscosity of 50 mPa·s or greater.
