Since the other guy is so unpleasant, Iíll ignore.

Often you are correct but what we are seeing here is a salt induced cloud point of an anionic surfactant. Basically, at low temperature, both surfactant and salt cannot dissolve in the available water. Raise the temperature and solubility increases and clouding goes away.

Cloud points at higher temperature are more commonly a result of nonionic surfactants.

Iíll leave it to the other guy now.
