Abstract:
1. A process for obtaining a stabilized ascorbic acid of a desired concentration of 15% (w/w) or less in solution, which comprises: a) dissolving a first amount of ascorbic acid in water, thereby obtaining a first solution; b) adding a first amount of ethoxydiglycol to said first solution, under a stirring speed sufficient to micronize ethoxydiglycol, ascorbic acid and water, thereby obtaining a second solution; c) adding a second amount of ascorbic acid to said second solution under a stirring speed sufficient to micronize same, thereby obtaining a third solution; d) adding a second amount of ethoxydiglycol to said third solution under a stirring speed sufficient to micronize same, thereby obtaining a fourth solution; and e) adding propylene glycol, which results into the obtention of a solution of ascorbic acid having the desired concentration.
