Most commonly, these are systems that are soluble at low temperatures and they show gelling or phase separation when the temperature is raised above a critical temperature (the lower critical solution temperature) that is usually called the cloud point.
PDVSA is also losing a major premium on ULSD spot prices being offered on the US Gulf Coast, while the Venezuelan diesel does not meet the EU's cold property requirements on cloud point and cold filter plugging point.
The cloud point is defined as the onset of turbidity of the solution.

Summary: A mixed micelle-mediated cloud point extraction (MMCPE) system was developed for the extraction and preconcentration of four synthetic phenolic antioxidants (SPAs) (propyl gallate (PG), tert-butylhydroquinone (TBHQ), butylated hydroxyanisole (BHA) and octyl gallate (OG) ) in cake.

It is known that at higher temperatures, an originally miscible blend may undergo a process going from original phase homogeneity to phase separation, which is a phenomenon known as cloud point transition with the critical point termed as LCST.
