Absorbent hydrophobic boronate galactomannan complexes and process for producing same

An absorbent material comprising one or more dried particles consisting of boronate galactomannan complexes that are precipitated from one or more hydrophilic organic solvents, said dried particles having a size ranging from about 80 μm to about 800 μm, wherein said boronate galactomannan complexes comprise a hydrophobic group, and said dried particles have a Free Swell Capacity (FSC) in a range between 45 g/g and 112.0 g/g and a Centrifuge Retention Capacity (CRC) in a range between 39.5 g/g and 91.0 g/g.
