Abstract
An odor control composition principally for use in closed recirculating and holding tank type chemical toilet systems comprises at least one substantially neutral or basic transition metal salt of an inorganic acid or a lower aliphatic organic monocarboxylic acid dissolved in aqueous ammonia or an aqueous solution of a strong water soluble organic amine which is subsequently acidified with sufficient mono- or polyfunctional carboxylic acid or other suitable acidic ligand to produce a transition metal coordination compound and a buffer system in aqueous solution, whose pH is at least about 6.5 and preferably is at least about 7.0. The composition may, optionally also contain, an inorganic oxidizing agent such as an alkali metal nitrate, alkali metal permanganate, or alkali metal chlorite, a wetting or emulsifying organic sulfonate or sulfate, and for esthetic purposes, a masking agent such as a fragrance and a neutral or alkaline stable dye.
