The present invention relates to an adhesive aqueous composition comprising a polysaccharide or a residual fraction from a pulping process comprising polysaccharide and an amine-functional polymer. The weight ratio between the polysaccharide and the amine-functional polymer is from 1:4 to 4:1; wherein the polysaccharideis hemicellulose or gum and with proviso that the composition has a pH of 6 or less when the amine-functional polymer is chitosan.

A roll of absorbent sheet tail-sealed with an NFC containing aqueous tail-seal adhesive includes an NFC containing aqueous tail-seal adhesive interposed between a tail of the roll of absorbent sheet and an underlying convolution of the roll adhering the tail to the underlying convolution to form the tail-seal. The NFC containing tail-seal adhesive comprises nanofibrillated cellulose and one or more additional components selected from the group consisting of components (i), (ii), (iii), (iv) and (v) wherein (i) is a water-soluble cellulose derivative; (ii) is a water soluble polyol; (iii) is a viscosity modifier other than a water soluble cellulose derivative; (iv) is PVOH; and (v) is PVOH and a viscosity modifier. The NFC containing tail-seal adhesive optionally includes a surface tension modifier other than PVOH.

A process is described for preparation of tunicate derived CNCs (T-CNCs) which exhibit a high aspect ratio, increased crystallinity and superior thermal properties compared to wood pulp derived CNCs (W-CNCs). The process enables scalable isolation of T-CNCs from tunicates, and a solution to the challenge invasive tunicates pose to aquaculture communities.
