A class or name given to a group of chemicals, usually caustic soda or sodium hydroxide. A substance which has the power to burn, corrode or eat away. Used in chemical manufacture, petroleum refining, pulp and paper, detergents, soap, textiles and vegetable oil refining.
The active ingredient in an alkaline bath, generally with a pHhigher than 10, which removes aluminum from used extrusion dies by etching. The primary ingredient, caustic Soda, dissolves the aluminum alloy by chemical reactions with no affect on the steel die.
harsh or corrosive in tone; "an acerbic tone piercing otherwise flowery prose"; "a barrage of acid comments"; "her acrid remarks make her many enemies"; "bitter words"; "blistering criticism"; "caustic jokes about political assassination, talk-show hosts and medical ethics"; "a sulfurous denunciation"
Alkali compounds at the higher end of the pH scale (those approaching pH 14). Sodium hydroxide (lye or caustic soda) is the most popular caustic used in the carwash industry. "Soda" was the cornerstone alkali builder in most detergents for decades. Since the 1980's, detergent manufacturers have become much less reliant on caustics because of their aggressive nature. Caustics may destroy objects they come in contact with - from car finishes and aluminum wheels to human tissue if they are handled improperly or carelessly.
A detrimental coffee taste sensation characterized by burning, sour sensation on the posterior sides of the tongue. Caused by alkaloids increasing the sourness of the acids in combination with a high percentage of salts.
Term used to describe any strongly alkaline material, which is corrosive to living tissue and wood. Caustic liquids cause a very high pH in wood. Wood substrates exposed to high pH may release excessive tannins, sometimes causing darkened wood. High pH in the wood surface can lead to premature finish failure if not properly neutralized.
Burning or corrosive. A hydroxide of a light metal. Broadly, any compound having highly basic properties. A compound that readily ionizes in aqueous solution to yield OH-anions, with a pH above 7, and turns litmus paper blue. See Alkaline, Base.
In optics, a caustic is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. Caustic can also refer to the curve to which light rays are tangent, defining a boundary of an envelope of rays as a curve of concentrated light. Therefore in the image to the right, the caustics can be the patches of light or their bright edges.
Caustic is an American industrial band based out of Madison, WI, created in 2002 by DJ Matt Fanale (AKA Eurotic), who is the sole consistent memberhttp://thisiscaustic.com/bio.html. The band's live lineup varies quite a bit, largely depending on the location of the show. Caustic's lyrics are typically really silly, while the music itself ranges between older styled industrial and more modern styled powernoise.
