A true grease consists of an oil or other fluid lubricant that is mixed with a thickener, typically a soap, to form a solid or semisolid. [1] Greases are usually shear-thinning or pseudo-plastic fluids, which means that the viscosity of the fluid is reduced under shear stress.
A handmade soap bar Two equivalent images of the chemical structure of sodium stearate, a typical ingredient found in bar soaps Emulsifying action of soap on oil. Soap is a salt of a fatty acid (sometimes other carboxylic acids) used for cleaning and lubricating products as well as other applications. [1]
Motor oil, a common lubricant. A lubricant (sometimes shortened to lube) is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.

Lithium 12-hydroxystearate (C 18 H 35 LiO 3) is a chemical compound classified as a lithium soap. In chemistry, "soap" refers to salts of fatty acids. Lithium 12-hydroxystearate is a white solid. Lithium soaps are key component of many lubricating greases.
These applications exploit its "non-stick" properties. [3] In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture. [4] It is an "activator" for accelerated rubber sulfur vulcanization. As discovered in the early days of vulcanization, zinc has a beneficial effect on the reaction of the sulfur with the polyolefin.
Murphy Oil Soap is commonly used to clean and polish horse tack, such as bridles and saddles. It is also commonly used to clean black-powder weapons after use, since the lack of petroleum-based oil and the presence of vegetable oil lessens the amount of sludge created when cleaning black powder residues from weapons.
Lithium grease in use. Lithium soap is a soap consisting of a lithium salt of a fatty acid. [1] [2] Sodium-based and potassium-based soaps are used as cleaning agents in domestic and industrial applications, whereas lithium soaps are used as components of lithium grease (white lithium).
