Dish washing process

A detergent composition comprising sodium citrate and an organo monophosphonic acid or a salt thereof of formula I

Machine dish wash compositions

A delivery device for delivering a dose of washing material, especially a detergent tablet, into the interior of a washing apparatus such as a machine dishwasher. In one preferred form, the device comprises:

Delivery device

The invention relates to a process of mechanically washing soiled articles with a wash liquor having a low pH and comprising silica material, to a mechanical dish washing composition producing a low pH and comprising silica, to a method of preparing a mechanical dish washing composition comprising silica, to silica granules as well as their preparation and to the use of silica material.

Washing process and composition

A substantially non-aqueous liquid detergent product comprising a liquid surfactant phase and a solid phase dispersed therein, the liquid surfactant phase comprising an ethoxylated alcohol having an average of from 5 to 8 ethylene oxide (EO) groups per molecule, at least 60% having a number of ethylene oxide groups within .+-.2EO of the average and the alkyl chain distribution being such that less than 2% has a chain length of 9 or less carbon atoms, at least 90% has a chain length between 10 and 12 carbon atoms and less than 10% has a chain length of 13 or more carbon atoms, said percentages being by weight of the ethoxylated alcohol.

Liquid non-aqueous detergents comprising narrow-range ethoxylates

An antifoam ingredient suitable for incorporation into a detergent powder comprises an antifoam material, for example, a hydrocarbon and/or a polysiloxane together with hydrophobic silica, enclosed within a matrix formed of a mixture of fatty acid and fatty acid soap.

Antifoam ingredient

Particulate alkaline detergent compositions for fabric washing, which include synthetic detergent compounds and alkali metal tripolyphosphate and alkali metal orthophosphate detergency builders, are made by spray-drying a detergent base powder containing some or all of the detergent compounds and some or all of the orthophosphate and admixing at least 2.5% by weight of the tripolyphosphate in particulate form with the spray-dried base powder.
