Abstract: The invention relates to a method for manufacturing a biodegradable composition containing nano-particles of cellulose for forming a protective coating on natural materials. It is an object of the invention to provide a composition for forming a protective coating layer on a biodegradable natural material that imparts to the material improved waterproofing and grease-resistant properties. It is another object to provide a composition for forming a protective coating on natural biodegradable materials that is based on the use of nano-cellulose particles and that protects these materials from swelling, warping, and mechanical damage during contact with water, other aqueous liquids, or grease.

Abstract: A novel, environmentally friendly and resource-saving method for the production of fractionally homogeneous compositions of microcrystalline cellulose (MCC) is provided. The method comprises of the following steps: (a) hydrolyzing cellulose-containing raw material with at least one acidic catalyst in the presence of at least one process additive at a low catalytic system/cellulose ratio; (b) neutralizing said acid with one or more precipitator in a manner that fine particles of insoluble ingredients precipitates into a slurry containing MCC; (c) admixing at least one modifier; following by (d), homogenizing of the composition so that a MCC product characterized by a uniformly dispersed micro-particle cellulose material and various functional ingredients is obtained.

Abstract: Composite cellulose containing materials which are waterproof and biodegradable are produced which consist essentially of cellulose and hydrophobic polymer-based composition in the amount about 4 to 40 wt %. The polymer-based composition comprises first polymer, which is partially saponified polyvinyl acetate, second polymer, which functions as plasticizer for improving elasticity of the first polymer and cross-linking agent, which is capable to cross-link the first polymer. The polymer-based composition may additionally contain environmentally friendly hydrophobizators, fillers and pigments.
