An aqueous finishing composition for cellulose-containing materials, comprising a hydroxyalkyl-functional organophosphorus flame retardant (which contains a substantially non-volatile component at the curing temperature) and a non-formaldehyde cross-linking agent (such as a polycarboxylic acid cross-linking agent), and the materials treated with such a composition. Optional ingredients for the aqueous finishing composition include a cross-linking catalyst and/or an inexpensive saturated alpha-hydroxy polycarboxylic acid such as citric acid (partial replacement of a more expensive preferred polycarboxylic acid will reduce finishing costs).

An aryl group containing phosphite, such as triphenyl phosphite, can be added to a reaction mixture comprising an organophosphorus compound, phosphorus pentoxide and an alkylene oxide, optionally in the presence of a reagent for the incorporation of hydroxy functionality in the final product. The aryl group containing phosphite is employed to improve the color characteristics of the resulting oligomeric organophosphorus composition.
