Abstract: A wood-derived lignin composition is disclosed. The wood-derived lignin composition comprises: - acid-insoluble lignin in an amount of 80 – 90 weight-% based on the total dry matter content of the lignin composition, wherein the average molecular weight of the lignin is 5000 – 15000 Da; - carbohydrates in an amount of 1.5 - 15 weight-% based on the total dry matter content of the lignin composition; - nitrogen in an amount of 0.2 – 1.5 weight-% based on the total dry matter content of the lignin composition; and wherein weight ratio of oxygen to carbon is at least 0.5 Further is disclosed a method for producing the wood-derived lignin composition.

Abstract: The invention relates to an aqueous emulsion of a hydrophobic anhydride-based sizing agent, prepared by homogenizing the said anhydride-based sizing agent in an aqueous phase which comprises a stabilizer, which is an anionic lignin-carbohydrate complex, where lignin and carbohydrate are covalently bound with each other. The invention further relates to a use of this anionic lignin-carbohydrate complex as a stabilizer as well as to a method for making an aqueous emulsion of a hydrophobic anhydride-based sizing agent.

Abstract: A lignin dispersion composition comprising spherical lignin particles dispersed in an aqueous medium, wherein the spherical lignin particles have a size exclusively within a range of 100 nm to 5 microns. Also described herein is a method of producing the lignin dispersion, by: (i) dissolving lignin in an organic solvent substantially devoid of water yet miscible with water to result in a solution of the lignin in the organic solvent; and (ii) producing the lignin dispersion by dialyzing the solution of the lignin with water until substantially all of the organic solvent is replaced with water with simultaneous formation of spherical lignin particles dispersed in the water. Also described herein is a method for stabilizing an emulsion by intimately mixing the emulsion with the lignin dispersion. Also described herein is a hierarchical assembly of porous microparticles produced by mixing the lignin dispersion with an emulsion and an amphiphilic block copolymer.
