METHOD FOR STABILIZE 5-AMINOLEVULINIC ACID

摘要

PURPOSE: A stabilization method of 5-aminolevulinic acid is provided to store the 5-aminolevulinic acid without reducing the activity of the 5-aminolevulinic acid for a long time. CONSTITUTION: A stabilization method of 5-aminolevulinic acid comprises the following steps: adding the 5-aminolevulinic acid to glycerin and stirring; and adding the mixture including the glycerin and the 5-aminolevulinic acid to fatty acid and stirring. The mixing process of the 5-aminolevulinic acid and the glycerin is performed at 50~80 deg C. The glycerin is capable of replacing into glycerin fatty acid ester, propylene glycol or butylene glycol. The fatty acid is selected from the group consisting of stearic acid, linoleic acid, linolenic acid or oleic acid.
