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.
He is the inventor of greasepaint. He wanted to conceal the joint between his wig and forehead, so he developed a flesh-coloured paste made of zinc white , ochre , and vermillion in lard . This formulation was so popular with other actors that Baudin began producing it commercially, and, as such, gave birth to the first theatrical makeup.

Anti-climb paint (also known as non-drying paint, anti-intruder paint, anti-vandal grease) is a class of paint consisting of a thick oily coating that is applied with a stiff brush, trowel or by hand using a protective glove.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Surfactants affect a wide array of physical properties in paints. Surfactants affect the behavior of a paint not only during the lifetime of the formed coating but also the initial aggregation and film formation of the paint.
Grease (lubricant), a type of industrial lubricant Grease, any petroleum or fat (including cooking fat) that is a soft solid at room temperature . Brown grease, waste vegetable oil, animal fat, grease, etc. that is recovered from a grease trap
Solid lubricants are useful for conditions when conventional lubricants are inadequate, such as: Reciprocating motion. A typical application is a sliding or reciprocating motion that requires lubrication to minimize wear, as, for example, in gear and chain lubrication.
In the eighteenth century, the developing science of chemistry expanded the range of pigments, which led to the discovery of Prussian blue and cobalt blue. In the nineteenth century, synthetic ultramarine was introduced, zinc white , viridian , chrome yellow , cadmium colours, aureolin , synthetic alizarin and cerulean blue .
