This invention provides for improved sterol nucleators of ice crystals. The improvement is the use of water stable crystalline forms of the sterols. These forms advantageously provide predictable nucleation temperatures which are stable for long periods of time, especially where the water is repeatedly frozen and thawed. In commercial ice making systems, the selection of stable forms of sterols having high nucleation temperatures provide great savings in construction and energy costs.
