Abstract
The present invention relates to cationic, gel forming, guanidinated polysaccharides of Formula I, their use as absorbent materials, and to processes for producing same: Formula I wherein Z1, Z2, and Z3 are independently selected from the group consisting of hydrogen, C1-C10 alkyl, substituted C1-C10 alkyl, C5-C7 cycloalkyl, and benzyl; and m is an integer ranging from 1 to 2,000,000. The absorbent guanidinated polysaccharides of Formula I have absorbent properties suitable for use in personal care products.
