This paper describes the effect of additive in the point of suitable concentration. It is thought that discussion of suitable concentration is very important for the application of ice storage. An oil-water mixture with additive with stirring is changed into suspension by cooling. The suspension was separated into ice and liquid in order to measure IPF. From the experimental result, this suspension had so high IPF (IPF=90%) in spite of the small depression of freezing point. Then, the shape and size of ice was observed by CCD (in the case of IPF=60%). The suitable concentration was discussed on the basis of the adhesion of ice to cooling wall, the depression of freezing point, and the shape and size of ice.
