Abstract
Synergistic mixtures of a dodecylguanidine salt with the condensation product of formaldehyde and ethanolamine wherein the molar ratio of the formaldehyde and ethanolamine in the condensation product is about 1:1.
Claims8
A synergistic antimicrobial mixture consisting essentially of a dodecylguanidine salt and a condensation product formed by reacting substantially equimolar amounts of ethanolamine and formaldehyde at the reflux temperature of the reaction mixture until the stoichiometric amount of water is formed, said condensation product being present in the mixture in a ratio of about 1:1 to about 15:1 by weight relative to said dodecylguanidine salt.
A method of inhibiting the growth of bacteria and fungi which comprises applying to said bacteria and fungi an inhibitorily effective amount of synergistic antimicrobial mixture consisting essentially of a dodecylguanidine salt and a condensation product formed by reacting substantially equimolar amounts of ethanolamine and formaldehyde at the reflux temperature of the reaction mixture until the stoichiometric amount of water is formed, said condensation product being present in the mixture in a ratio of about 1:1 to about 15:1 by weight relative to said dodecylguanidine salt.
