As the cooling pack clear formula is chilled in either ice and water for 20-30 minutes or the freezer for 35-45 minutes. It "phase changes" to a white semi-solid. It never turns completly solid and never gets cold as ice. As formula absorbs heat from torso, where about 90% of the bodies heat is produced, it " phase changes" back to its original liquid state.
