Abstract

The present invention relates to a method for stabilization of ethoxyquin in aqueous C1-C3 carboxylic acid - containing solutions, where 0.1 - 0.5 weight % ascorbic acid, preferably 0.3 - 0.4 weight % and/or 0.1 - 1 weight % sulphite, preferably 0.4 - 0.7 weight % is added to said solution. The invention also relates to aqueous C1-C3 carboxylic acid - containing solutions comprising ethoxyquin as antioxidant, where said solution comprises 0.1 - 0.5 weight % ascorbic acid, preferably 0.3 - 0.4 weight %, and/or 0.1 - 1 weight % sulphite, preferably 0.4 - .07 weight %. The invention also relates to the use of ascorbic acid sulphite for stabilization of ethoxyquin in aqueous C1-C3 carboxylic acid - containing solutions.
