Abstract
The stabilization of aqueous or alkanolic solutions of choline and derivative of choline against discoloration on aging by the addition of an unsubstituted hydroxylamine salt to the choline solutions at levels of less than 1 percent.
Claims11
A stabilized choline solution comprising choline or a salt thereof;
- a solvent selected from the group consisting of water, alkanols of 1 to 8 carbon atoms and mixtures thereof;
- and a stabilizing concentration of an unsubstituted hydroxylamine salt to prevent decomposition of said choline or salt thereof.
The process of stabilizing a choline salt when stored in an admixture with a hydroxyl containing compound which comprises adding to the solution of said choline salt stored, an unsubstituted hydroxylamine salt at levels of less than 1% and a solvent selected from the group consisting of water, alkanols of C.sub.1 to C.sub.8 and mixtures thereof.
