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.

Claims (8)

1. A composition comprising sucrose fatty acid ester particles containing one or more cargo materials comprising a latex.

2. The composition of claim 1 , wherein said latex comprises a solid latex polymer bead.

3. The composition of claim 1 , further comprising thymol, lecithin, alkyl glucosides and combinations thereof.

4. The composition of claim 1 , wherein the particles are micelles, microcapsules or nanocapsules.

5. The composition of claim 1 , wherein the sucrose fatty acid ester is a mono- or diester.

6. The composition of claim 1 , wherein the sucrose fatty acid ester comprises all saturated fatty acids or is a mixture of saturated and unsaturated fatty acids.

7. The composition of claim 1 , wherein the fatty acid ester particles comprise one or more sucrose fatty acid esters.

8. The composition of claim 1 , wherein said one or more cargo materials comprises calcium carbonate, titanium dioxide, kaolin clay, silica, silicate, talc, mica, or a combination thereof.
