A Society of Automotive Engineers (SAE) motor oil viscosity classification. SAE summer grades are defined by viscosity ranges. For example, SAE 30 oil will have a minimum low-shear rate, kinematic viscosity of 9.3 cSt (at 100 °C), and a maximum of less than 12.5 cSt (at 100 °C), and also will have a minimum high-shear rate absolute viscosity of 2.9 cP (at 150 °C). SAE winter grades are defined by, in addition, maximum viscosities at specified low temperatures, and carry a W suffix. Multigrade oils meet combined winter and summer specifications and have combined designations such as SAE 10W-30.

A graphical representation of the viscosity of a system versus salt concentration. This curve can be an important characteristic of formulated systems in which viscosity control is necessary, such as in shampoo formulas.
A foam made from a surfactant solution having a high salt content. Some versions of salt foam are made to be placed on top of drinks intended for human consumption such as margaritas. Also termed salt air.
Solutions: When the addition of electrolyte to a solution causes an increase in the solubility of a solute. See also Salting Out.
Surfactants: When the addition of electrolyte to a solution of nonionic surfactant causes the critical micelle concentration to increase. Also, addition of electrolyte to an ...
