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

A method for manufacturing a shaped article comprising the step of cutting a shaped article from a first article; wherein as the shaped article is cut from the first article the shaped article's cross-section is deformed and wherein the first article's cross-section is shaped such that it compensates for the deformation during the cutting step so as to achieve a shaped article with a desired cross-section. Shaped articles and compositions comprising shaped articles are also described.

Method for manufacturing a shaped article

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 auxiliary composition comprising from 0.001 wt % to 99 wt % cleaning polymer having a hydrophilic backbone and at least one hydrophobic pendant group, and an adjunct ingredient in which the hydrophilic backbone constitutes less than 50%, preferably less than 45% by weight of the polymer. The detergent auxiliary composition may be, for example a spray-dried particle or an agglomerate. Also described are detergent compositions comprising the detergent auxiliary composition.

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.

The residual chlorine content of a polyolefin-substituted carboxylic acylating agent formed by a chlorine-assisted reaction of a polyolefin and an &agr;,&bgr;-unsaturated carboxylic reactant can be reduced by heating the polyolefin-substituted carboxylic acylating agent having a residual chlorine content in the presence of an &agr;,&bgr;-unsaturated carboxylic reactant, optionally in the further presence of a sulfonic acid. Residual chlorine content can be further reduced by using, in the reaction of the polyolefin &agr;,&bgr;-unsaturated carboxylic reactant, a high speed mixer provided with a dual pitch blade.

Polyalkene-substituted carboxylic acid compositions having reduced chlorine content

A solid bleach precursor composition is provided comprising a bleach precursor and a surfactant system, whereby the composition exhibits effective solublisation of its bleach precursor component.
