Bivalent iron compounds

A composition comprising an aqueous solution, said aqueous solution comprising:

• (a) 1.0 mol of an iron compound;
• (b) 0.1 to 3.0 mol of a reducing material;
• (c) 0.1 to 3.0 mol of an amino acid;
• and
• (d) 1.0 liter of water to form the aqueous solution, said aqueous solution is diluted to have an iron concentration from about 1×10−6 to about 1×10−21 moles per liter, and wherein the composition is selected from the group consisting of a skin lotion, a skin oil, a hair tonic, a shampoo and a detergent, wherein said aqueous solution is present in an effective amount to improve said composition.

A method for treating an inorganic material comprising the steps of:

• (i) immersing said inorganic material in an aqueous solution, the aqueous solution comprising:
• (a) 1.0 mol of an iron compound;
• (b) 0.1 to 3.0 mol of a reducing material;
• (c) 0.1 to 3.0 mol of an amino acid;
• and
• (d) 1.0 liter of water;
• (ii) removing said inorganic material from the aqueous solution,
• wherein from about 0.1 to about 3.0 moles of reducing material and from about 0.1 to about 3.0 moles of amino acid are added to about 1.0 mol of bivalent iron compound and about 1.0 liter of water to form the aqueous solution, and
• wherein when said aqueous solution is used, said aqueous solution is diluted to have an iron concentration from abut 1×10−6 to about 1×10−21 moles per liter.
