Abstract
Provided is a solvent borne dust suppressant or stabilization composition in a solvent which includes, a blend of an inorganic salt and a lignin-carbohydrate mixture, optionally with one or more of a surfactant and crosslinker, wherein the lignin-carbohydrate mixture may be a copolymer and may be present in an amount of 5 weight % to 50 weight % solids, wherein the lignin is a low average molecular weight lignin, the carbohydrate includes hemicellulose and wherein the lignin and hemicellulose are substantially derived from a non-wood source, a wood source or a blend thereof.

A dust suppressant and soil stabilization composition comprising a solvent borne blend of solids, the solids comprising:
- (i) an inorganic salt in an amount of 1 weight % (or 2.0 or 5.0 weight %) to 20 weight % (or 10 or 15 or 18 weight %) solids,
- (ii) a lignin-carbohydrate mixture in an amount of 5 weight % (or 15 or 20 or 30 weight %) to 35 or 40 or 50 or 60 or 70 weight % solids,
- wherein the solvent comprises
- a. water, and
- b. less than 5% by volume (or 2.5 or 1% by volume) with respect to the solvent of a C1-C10 alcohol,
- wherein the composition has a pH in the range of 7.0 to 11.
A method of agglomerating dust on a surface, the method comprising applying to the dust on a surface a solvent borne blend of solids comprising:
- (i) an inorganic salt in an amount of 1 weight % (or 2.0 or 5.0 weight %) to 20 weight % (or 10 or 15 or 18 weight %) solids,
- (ii) a lignin-carbohydrate copolymer in an amount of 5 weight % (or 15 or 20 or 30 weight %) to 35 or 40 or 50 or 60 or 70 weight % solids,
- wherein the solvent comprises water,
- wherein the composition comprises less than 1500 parts per million (ppm) (or 200, or 100 or 50 ppm) of sulfur, and
- wherein the composition is substantially free of anthraquinone.
