Disclosed is a process for solubilising cellulose and coagulating the resulting solution to form a cellulose-containing material. The process comprises contacting a cellulose source with a solvent comprising zinc ions and formic acid to provide a solution, coagulating the solution to provide a solid material, treating the solid material, and isolating the solid material after treatment, to provide the cellulose-containing material. The process can further comprise solubilising protein and coagulating the resulting solution to form a cellulose/protein-containing material. The cellulose-containing materials and cellulose/protein-containing materials can be produced, for example, as reconstituted fibres and films.

An aqueous base, glue-free composition is comprised of an effective amount of ingredients (e.g., arabic gum, casein and polyvinylpyrrolidone) which exhibit sticky adhesion properties which do not tightly bind so as to allow an eyelash extension to be removably attached to a natural eyelash without the need for use of adhesive remover composition.

The present invention provides processes that promote the solvation of calcium ions in macromolecular matrices. Processes in which the relationship, concentration, physicochemical conditions at each stage and preparation methods allow to obtain a stabilized soluble product, based on calcium salts and polymers. The present invention does not result in the deposition of crystals of the salts used, and exceeds the commercial calcium formulations so they are of great utility for their application in the food, pharmaceutical and/or cosmetic industry.

An aqueous adhesive composition and a process for preparing such compositions are disclosed. The composition comprises macromolecular complex comprising (A) a first component comprising (i) a framework element and (ii) a polyphenol, and (B) second component comprising a polypeptide, oligopeptide, amino acid, or polyamine. The framework element comprises (a) a polypeptide, oligopeptide, amino acid, or polyamine, (b) a polysaccharide, oligosaccharide, or monosaccharide, or a saccharide conjugate, or (c) a lignin, a lignan or a lignin conjugate. The polyphenol comprises a tannin, a tannic acid, a flavonoid, or a poly-resorcinol. An adhesive precursor composition comprising the first component is also disclosed.
