Compositions and methods of rendering cellulosic materials fire retardant, and articles of manufacture including the materials, are disclosed. The compositions include an amino acid, protein and/or peptide and optionally include one or more crosslinking and/or coupling agents. Enzymes are a preferred protein. The methods involve applying the composition to the material, and optionally involve covalently linking the amino acid, protein and/or peptide to the material, either directly or via a crosslinking agent. An advantage of covalently linking the amino acid, protein and/or peptide to the cellulosic material is the lack of any potential toxicity associated with breathable dust particles of unbound amino acid, protein and/or peptide, and the stability of the bonds between the material and the amino acid, protein and/or peptide to conventional steam cleaning and other carpet cleaning methods. In a preferred embodiment, the fire-retardant cotton-fiber composition is used to prepare cotton carpets, upholstery or raised surface apparel.
