Blue spirulina powder M18 has poor heat, light, and acid stability, while it is stable under weak acid and neutral conditions (PH4.5-8). However, precipitation will occur under acid conditions, and strong alkali can make phycocyanin discolored. It has poor stability to metal ions and poor chromaticity.

When added to other solvents, it dissolves quickly in cold and warm water, precipitation occurs if used in 100% alcohol, but it can be dissolved in solutions with less than 20% alcohol.
