Novel processes for incorporating anti-scalant agents having acidic functionalities in zero-P or low phosphate built powder detergents to provide an automatic dishwashing detergent of improved solubility.

Processes for incorporating anti-scalants in powdered detergent

Compositions suitable for use as detergents comprise a non-silicate-coated alkali metal phosphate salt hydrated to at least about 50% by weight, and an inorganic salt selected from alkali metal carbonates and sulfates. The compositions for use in, e.g. dishwashing, have improved solubility and dispersion characteristics.

Hydrated alkali metal phosphate and silicated salt compositions

A fabric conditioning and brightening composition especially effective toward polyester textiles is disclosed comprising a cationic fabric softening compound, a cotton- or nylon-substantive fluorescent whitening agent and a carboxylic acid containing at least 10 carbon atoms.

Polyester fabric conditioning and whitening composition

The present invention relates to a powder detergent composition of improved solubility and methods of making them. The composition comprises a silicate free alkaline blend consisting essentially of about 10-60% builder, about 0.6-6% surfactant. about 20-50% alkaline agent and 0-70% filler; and an admixture of said blend with about 10-30% of solid alkali metal silicate and a chlorine donor providing about 0.4-1.5% available chlorine, the pH of the resulting finished product being about 10.4 or greater at about a 0.25% product use concentration.

Detergent powders of improved solubility

The premature release of chlorine from chlorine-releasing bleaching agents in a particulate detergent, caused by the action on such a bleaching agent by some other component in the detergent, is prevented by compacting and granulating a mixture of said other component, preferably with additional constituents which do not have the chlorine-releasing effect, and then mixing those granules with the chlorine-releasing bleaching agent and other appropriate detergent constituents. The resulting novel detergent is a mixture of the thus-produced granules with particles of the said other appropriate detergent constituents.
