Most complexes are stable to ambient conditions of heat, relative humidity and light.
However, the recommended method of storage is in a tightly closed container kept in a cool, dry place out of bright light. Under these conditions, most complexes will be stable for many years. General method of complexation with Trappsol CMCD's In general, powdered CMCD is dissolved in water, the compound is added, stirred for some length of time, filtered, and water is removed. The compound to be complexed should be added in excess - small additions followed by stirring or sonicating until a clear solution develops can be repeated until no more active ingredient will go into solution. Checking a small filtered sample of the complex by UV absorption or TLC may show how the incorporation rate is increasing over time.
