Fire retardant composition for treatment of various wood products, method of producing the same and uses thereof. The compositions comprise an aqueous solution of bisphosphonate selected from 1-hydroxyethane 1,1-diphosphonic acid, an alkanol amine, and optionally an alkaline agent, the composition having a pH in the range of 4.0 to 7.0. The composition can be produced by mixing together 30 to 50 parts by weight of 1-hydroxyethane 1,1-diphosphonic acid; 1 to 10 parts by weight of an alkanol amine or mixture thereof, said alkanol amine being added in free form; and optionally 0.1 to 40 part by weight of an alkaline agent; and water. The compositions can be used for protecting wood not only against fire but also against mould, rot, blue stain, insect such as termite attacks on wood, dimensional changes, or a combination thereof due to environmental influence.
