20140148509 | STABILIZED ASCORBIC ACID SOLUTIONS; METHOD OF USE THEREOF; PROCESS FOR THEIR OBTENTION; AND COMPOSITIONS COMPRISING THE SAME - This invention relates to improved solutions comprising ascorbic acid (vitamin C). These solutions may comprise as much as 15% ascorbic acid; they are stable for at least two years, without no significant development of yellowish coloration and no substantial (not more than 10%) degradation of the vitamin. The process involves sequential additions of ascorbic acid and ethoxydiglycol to a first solution of vitamin in water, which are followed by addition of propylene glycol. The stirring speed that occurs during the additions favors a process of micronization. Mild heating is used to achieve ascorbic acid concentrations equivalent to about 6% in 10% water or higher. | 05-29-2014 |
