Publication No.: GB2609040A 25/01/2023

Applicant:

CELLUCOMP LTD [GB]

Absstract of: GB2609040A

A process for preparing a cellulose-containing microporous superabsorbent composition includes comminuting dry granulated herbaceous plant material, e.g. sugar beet, orange peel or apple residue, to form microparticles having an average particle diameter from 100μm to 800μm. Preferably the method includes contacting the microparticles with an aqueous alkaline solution, neutralising and/or washing the mixture, removing fluids from the mixture, and drying the obtained material. The starting material may comprise less than 20wt.% lignin. The superabsorbent composition may have a water absorption capacity (WAC) in the range of from 2 to 10. The cellulosic superabsorbent composition may be a material which comprises a fluid-superabsorbent volume area able to absorb 3-6 times of the original weight within 30 seconds, and may exhibit a virucidal activity as expressed by a reduction in viral titre of influenza A and/or human coronavirus of above 90% as determined pursuant to ISO18184:2019. The material may be in the form of a medical, surgical, sanitary or protective article, e.g. a dressing, pad, tampon, gown, glove etc, a packaging material or a particulate absorbent for spills. An antimicrobial or other functional agent may be adhered to the material to form a functionalised superabsorbent composition.
