Abstract
The present invention relates to a three-dimensional cellulosic molded body that has an optically detectable core/shell structure, the shell having a higher density and a lower crystallinity than the core, and the core having a sponge-like structure. The invention further relates to a method for producing this molded body as well as to its use, especially in the cosmetics and pharmaceutical industries.
Claims25
A three-dimensional cellulosic molded body comprising an optically detectable core/shell structure, the shell having a higher density and a lower crystallinity than the core, the core having a sponge-like structure, wherein the shell has a relative density from 65% to 85% and the core has a relative density from 20% to 60%—related to compact cellulose, wherein the shell has a thickness between 50 μm and 200 μm, and wherein a ratio of the shell thickness to a total diameter of the molded body is between 1:5 and 1:50.
