If you have always leave a half-empty can of paint in an unheated throw or garage during the winter, you have probable question, what bechance if pigment freezes. The little result is that freeze temperatures can permanently compromise the chemical structure of most blusher, turning a dead good product into a lumpy, unuseable mess.

When the temperature drop below 32°F (0°C), the h2o substance expand as it turns to ice. This elaboration exerts pressure on the polymer binders that continue the pigment suspended, causing them to snap or clot.
Oil-based pigment, conversely, is mostly more resistant to freeze because its solvents are not water-based.
