Abstract

The present disclosure describes methods of treating fibrous cellulosic materials with sucrose fatty acid ester containing particles (carrier systems) that allow for modifications of surfaces, including making such surfaces water resistance and/or oil/grease resistance. The methods as disclosed provide combining at least one saccharide fatty acid esters (SFAE) with a polymer (e.g., latexes) to form micellular particles and applying such particles to substrates including fibrous cellulose-based materials (e.g., pulp) to form, inter alia, molded products. Compositions comprising combinations of SFAE, a latex and optionally a mineral or other additives are also disclosed.
