Abstract
Abstract A granular colored speckle is provided having non-staining qualities comprising a granular, water-soluble, hydratable, inorganic alkaline salt agglomerated with an anionic surfactant paste as the adhesive agent containing the coloring agent. The granular colored speckle is particularly useful in admixture with white or lightly colored detergent granules to provide a speckled composition.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
185 words
The method of making a low- or non-staining colored speckle which comprises agglomerating from 60 to about 85%, by weight of the granular colored speckle, of a granular, water-soluble, hydratable inorganic alkaline salt selected from the group consisting of sodium tripolyphosphate, sodium pyrophosphate, sodium orthophosphate, and mixtures thereof, with from about 15 to about 35% by weight of the granular colored speckle, of an aqueous anionic surfactant paste comprising from about 20 to about 50%, by weight, of an anionic surfactant selected from the group consisting of sodium alkylbenzene sulfonates having 10 to 14 carbons in the alkyl chain, sodium coconut alkyl sulfate, sodium tallow alkyl sulfate, the sodium salt of the sulfated condensation product of C 10 to C 18 alcohols having an average of 3 moles of ethylene oxide per mole of alcohol, and mixtures thereof, and having admixed in said paste from about 0.5 to about 10%, by weight of the granular colored speckle, of a coloring agent selected from the group consisting of phthalocyanine blue, phthalocyanine green, ultramarine blue, Polar Brilliant Blue, Rhodamine BM, Pontacyl Light Yellow 36 and mixtures thereof.
