A multi-compartment pouch having a particulate dishwashing product final bulk density is preferably at least about 0.6 g/cc, the builder not containing a phosphate.

Dishwashing method

The present invention relates to a solid laundry detergent composition in particulate form, comprising: (a) anionic detersive surfactant; (b) a calcium-augmented technology; (c) from 0% to less than 5%, by weight of the composition, of zeolite builder; (d) from 0% to less than 5%, by weight of the composition, of phosphate builder and (e) optionally, from 0% to less than 5%, by weight of the composition, of silicate salt.

Solid laundry detergent composition comprising anionic detersive surfactant and calcium-augmented technology

A pouch, and a process for making thereof, comprising the steps of: pre-sealing a compartment comprising a pouch material, the compartment containing an anhydrous composition to form a pre-sealed compartment; fitting a first piece of the pouch material into a mould, pouring a particulate dishwashing product into the mould; placing the pre-sealed compartment over the mould; sealing the pre-sealed compartment and said first piece of pouch material together to form the multi-compartment pouch.

A method of washing dishware/tableware in an automatic dishwashing machine, the method comprising simultaneously or sequentially delivering quantities of a particulate or densified particulate automatic dishwashing product and of an anhydrous liquid, gel or paste form dishwashing detergent auxiliary contained in separate compartments of a multi-compartment pouch into the same or different cycles of the dishwashing machine. The method provides improved cleaning performance and product stability.

A detergent composition in the form of a substantially anhydrous liquid, gel or paste and which comprises a premix of an amine oxide surfactant and a solvent therefor selected from Cto Calkylene and polyalkylene diols and mixtures thereof. The invention also relates to unit dose forms containing the detergent compositions and processes for making a premix for use in said compositions.

Detergent composition

A method of washing dishware/tableware in an automatic dishwashing machine having a single or multi-compartment product dispenser which is normally closed and sealed after charging the machine and prior to delivery of the dishwashing product into the wash liquor and wherein the dishwashing product comprises one or more dishwashing compositions in a unit dose form having a degree of deformability greater than about 10% and a shape and size such that the dishwashing product occupies more than about 60%, preferably more than about 85% of the volume of the corresponding compartment of the product dispenser in its closed state. The method allows for optimum delivery of active components across different washing machine types.
