Abstract: Solvent-free coating materials and treating agents used as water-based wood or material protective agents containing emulsifiable binding agents, quaternary ammonium compounds and optional additional active agents. The wood or material protective agents are non-flammable and enable a uniform distribution of the binding agent and the quaternary ammonium compounds in the substrates. As a result, the quaternary ammonium compounds function as a dissolving mediator for the binding agents which are dispersed in water without opacifying effects and are used as a biocide. The agents can additionally absorb water-insoluble organic biocides without impairing the homogeneity or stability of the formulation of the homogeneity of the distribution in the substrate.

Abstract: This invention relates to a bivalent iron compound comprising a bivalent iron salt, an amino acid and a reducing material. It is known that bivalent iron salts exhibit specific effects in wide applications, for example, agricultural applications such as modification of soil quality, fishing applications such as quality preservation of fishes, medical applications such as treatment of diseases and industrial applications such as prevention of metal corrosion and purification of waste water and exhaust gas.
