A disperse phase of an emulsion comprises drops containing different compounds which can react to cause a color change when the continuous phase forms crystals as it freezes. - A water-in-oil (W/O) emulsion used as a freezing point indicator is designed to break down when cooled to below a given temperature. The disperse phase of the emulsion is formed by drops containing different reactive compounds which give rise to a noticeable color change when they undergo a reaction when a significant proportion of the drops are combined. The continuous phase of the emulsion is chosen so that it forms crystals combining the drops in the disperse phase when it freezes. |
