cloud point

https://doi.org/10.1351/goldbook.12241
Point in the isobaric temperature-composition plane of a binary or multicomponent mixture at which a decrease in transparency is observed due to the turbidity caused by phase separation.
Notes:
  1. A cloud point is characterized by the first appearance of turbidity or cloudiness.
  2. A cloud point can be induced by varying temperature or composition.
  3. A cloud point induced by varying temperature is heating-rate or cooling-rate dependent.
