Abstract
Abstract Pulverulent dyestuffs of all kinds are made highly resistant to dusting by dispersing into the powder a small amount of mineral oil that boils within the range of 140° to 310° C, and an emulsifier having a polyethoxy hydrophile. These additives can be premixed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
In a dyestuff formulation having added material dispersed in it to impart dusting resistance to the formulation when powdered, the improvement according to which the added material is a mixture of a mineral oil boiling in the range of from about 140° to about 310° C, and emulsifier having a polyethoxy hydrophile in an amount sufficient to disperse the oil.
Claim 2
Dependent Claim
60 words
In a dyestuff formulation having added material dispersed in it to impart dusting resistance to the formulation when powdered, the improvement according to which the added material is a mixture of a mineral oil boiling in the range of from about 140° to about 310° C, and emulsifier having a polyethoxy hydrophile in an amount sufficient to disperse the oil.
Claim 3
Dependent Claim
37 words
The combination of claim 1 in which the mixture is from about 0.05 to about 3% by weight of the formulation solids, and the weight ratio of emulsifier to oil is from about 35:65 to about 5:95.
Claim 4
Dependent Claim
50 words
The combination of claim 1 in which the emulsifier is a polyethoxylated fatty alcohol, fatty acid, fatty acid amide or alkylphenol, the fatty chain of the fatty alcohol, fatty acid and fatty acid amide having 7 to 30 carbons, and the alkyl of the alkylphenol having 4 to 12 carbons.
Claim 5
Dependent Claim
20 words
The combination of claim 3 in which the emulsifier is a polyethoxylated stearyl alcohol, oleyl alcohol or coconut oil alcohol.
Claim 6
Dependent Claim
19 words
The combination of claim 1 in which the polyethoxy chain has 5 to 15 ethylene oxide units per mol.
Claim 7
Dependent Claim
28 words
The combination of claim 1 in which the emulsifier is the reaction product of stearyl alcohol with, on a statistical average, 5 to 7 mols of ethylene oxide.
Claim 8
Dependent Claim
16 words
The combination of claim 1 in which the mineral oil is essentially a refined petroleum fraction.
Claim 9
Dependent Claim
22 words
The combination of claim 1 in which the mineral oil boils in the range of from about 180° to about 280° C.
Claim 10
Dependent Claim
19 words
The combination of claim 1 in which the dyestuff is an azo, anthraquinone, methine, quinophthalone, indigo or thioindigo dyestuff.
Claim 11
Dependent Claim
38 words
A mixture of about 65 to about 95% by weight mineral oil boiling in the range of about 140° to about 310° C, with about 5 to about 35% by weight of an emulsifier having a polyethoxy hydrophile.
Claim 12
Dependent Claim
38 words
A mixture of about 65 to about 95% by weight mineral oil boiling in the range of about 140° to about 310° C, with about 5 to about 35% by weight of an emulsifier having a polyethoxy hydrophile.
