SUPER-ABSORBENT COMPOSITION COMPRISING TANNINS FOR ODOR CONTROL

摘要

The present invention relates to a water-absorbent composition, comprising water-absorbent polymer structures having at least one tannin fraction on the surfaces thereof, said fraction having a specific average molecular weight of at least 1,000 g/mol determined according to the testing method described herein, or being a hydrolyzable gallotannin. The present invention also relates to a method for the production of a water-absorbent composition, the water-absorbent composition obtained by said method, a composite, a method for the production of a composite, the composite that can be obtained by said method, chemical products such as hygienic articles, to the use of a water-absorbent composition or of a composite, and to the use of a tannin fraction.
