Abstract
A novel composition of matter comprising a color-inhibiting additive, such as sodium bisulfite, and cis-1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride or the cis-, trans- mixtures of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane chloride, is a non-yellowing antimicrobial formulation suitable for the preservation of aqueous organic mixtures such as emulsions, dispersions, latexes and solutions. The color-inhibiting agent may be added as a solid or as an aqueous solution wherein the weight ratio of adamantane to additive is from about 1:0.01 to about 1:4.
