ABSTRACT:
A composition containing a continuous aqueous phase comprising L-2-oxothiazolidine-4-carboxylic acid, at least one sequestering agent and at least one neutralizing agent, the said neutralizing agent being present in an amount which is sufficient to adjust the pH of the aqueous phase of the composition to a value of between 5 and 8. The combination of the sequestering agent and the neutralizing agent stabilizes the L-2-oxothiazolidine-4-carboxylic acid, in particular with respect to thermal degradation, and thus prevents yellowing of the composition and the formation of unpleasant odors.
