Sapindin, from Soapnut Tree, may have potential application as a natural cleansing agent and for decolorizing stained teeth.

As for other methods of skin whitening, other decolorizing chemicals can be used. Aesthetic skin decolorizing surgeries can also be performed, but excessive cleansings can cause a number of problems, such as facial inflammation, but in the 2000s this is in decline. Historically, the droppings of the have been used as an ingredient in face-washes for whitening skin.

Alkynes react similarly, forming the tetrahalo compounds. This is sometimes known as "decolorizing" the halogen, since the reagent X2 is colored and the product is usually colorless and odorless.

Examples of bioprospecting products used in bioremediation include Coriolopsis gallica- and Phanerochaete chrysosporium-derived laccase enzymes, used for treating beer factory wastewater and for dechlorinating and decolorizing paper mill effluent.

Ammonium, sodium, and potassium salts of H2SO5 are used in the plastic industry as polymerization initiators, etchants, desizing agents, soil conditioner, and for decolorizing and deodorizing oils. Potassium peroxymonosulfate, KHSO5, is the potassium acid salt of peroxymonosulfuric acid. It is widely used as an oxidizing agent.

The Kinyoun method can be modified as a weak acid fast stain, which uses 5% sulfuric acid instead of hydrochloric acid. The weak acid fast stain in addition to staining mycobacteria will stain organisms that are not able to maintain the carbol fuchsin after decolorizing with HCl.

It is still used to some extent in laboratory practice. The decolorizing power is not permanent, becoming lost after using for some time; it may be revived, however, by washing and reheating. Wood charcoal also to some extent removes coloring material from solutions, but animal charcoal is generally more effective.

In both methods, after filtration, the crystalline product is triturated with acetone. If no solid separates, ethyl acetate is added to precipitate the crude product. The product is then dissolved in hot ethanol and treated with decolorizing charcoal. Ethyl acetate is added to the filtered solution to precipitate the crystalline product.

One of the earliest applications of sodium selenate was in the glass industry. Selenium produces a red hue in glass. The molten glass is treated with sodium selenate and then arsenic trioxide to reduce the compound and provide elemental selenium. Sodium selenate is also used as a decolorizing agent in glass production.

Bentonites are used for decolorizing various mineral, vegetable, and animal oils. They are also used for clarifying wine, liquor, cider, beer, mead, and vinegar. Creating a bentonite slurry for fining after wine pressing The main uses of bentonite are as drilling mud, binder (e.g. foundry-sand bond, iron ore pelletizer), purifier, absorbent (e.g.

Dye-decolorizing peroxidase (, DyP, DyP-type peroxidase) is an enzyme with systematic name Reactive-Blue-5:hydrogen-peroxide oxidoreductase. This enzyme catalyses the following chemical reaction : Reactive Blue 5 + H2O2 \rightleftharpoons phthalate + 2,2'-disulfonyl azobenzene + 3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]benzenesulfonate These heme proteins are secreted by basidiomycetous fungi and eubacteria.

Some carbons are more adept at adsorbing large molecules. Molasses number or molasses efficiency is a measure of the mesopore content of the activated carbon (greater than 20 Å, or larger than 2 nm) by adsorption of molasses from solution. A high molasses number indicates a high adsorption of big molecules (range 95–600). Caramel dp (decolorizing performance) is similar to molasses number.

Pyrolusite is also used to prepare disinfectants (permanganates) and for decolorizing glass. When mixed with molten glass it oxidizes the ferrous iron to ferric iron, and so discharges the green and brown tints (making it classically useful to glassmakers as a decolorizer). As a coloring material, it is used in calico printing and dyeing; for imparting violet, amber, and black colors to glass, pottery, and bricks; and in the manufacture of green and violet paints.

Elizabeth Gertrude Holliday (23 May 1925—3 April 2011), known professionally as Betty Holliday and Betty Holliday Deckoff, was an American visual artist and educator who was active on Long Island, New York, and in New York City. Her most well-known works are large figurative paintings and drawings. Her early paintings were dominated by color, as she was trained when Abstract Expressionism was the dominant American art movement; later she became interested in photography and, as a result, experimented in "decolorizing" her paintings and drawings.

Although activated carbon may be implemented as a flow-through filter, it is also commonly utilized as a batch ingredient, which later must be separated and discarded from the beverage. It can completely/partially remove benzenoid compounds and all classes of polyphenols non-specifically, decolorizing and deodorizing juices and wines. Traditionally, yeast fining has involved the addition of hydrated yeasts used as adsorption agents. Consisting of approximately 30% protein, yeast cell walls have a chemical affinity with wine compounds, such as those that may be polyphenolic or metallic.

Animal charcoal or bone black is the carbonaceous residue obtained by the dry distillation of bones. It contains only about 10% carbon, the remaining being calcium and magnesium phosphates (80%) and other inorganic material originally present in the bones. It is generally manufactured from the residues obtained in the glue and gelatin industries. Its decolorizing power was applied in 1812 by Derosne to the clarification of the syrups obtained in sugar refining; but its use in this direction has now greatly diminished, owing to the introduction of more active and easily managed reagents.

Types of endospores that may be identified include free endospores, central endospores, central and swollen endospores, and subterminal endospores. Mycobacterium is one obstacle that is faced with this type of staining because it will still stain green even though it does not produce any endospores. This is due to its waxy cell wall which retains the malachite green dye even after the decolorizing process. A different type of staining called acid-fast stain will have to be done in order to get further information about this particular type of bacterium.

Sugars (clockwise from top-left): white refined, unrefined, unprocessed cane, brown Historically, bone char was often used in sugar refining as a decolorizing and deashing agent, particularly in cane sugar as this contains more colored impurities. Bone char possesses a low decoloration capacity and must be used in large quantities, however, it is also able to remove various inorganic impurities, most importantly sulfates and the ions of magnesium and calcium. The removal of these is beneficial, as it reduces the level of scaling later in the refining process, when the sugar solution is concentrated. Modern alternatives to bone char include activated carbon and ion-exchange resins.

Rosé Champagnes can range in color from pink to copper. Rosé Champagnes account for between 3-5% of Champagne's yearly production. These Champagnes are distinct from Blanc de noirs (white of blacks or white from black grapes) in that rosé Champagnes are often noticeably and intentionally colored, with hues that span from "baby pink" to copper salmon, while Blanc de noirs are white wines with only sometimes the palest of coloring that could range from a "white-grey" to a light salmon. This color traditionally comes from the very brief skin contact of the black grapes (Pinot noir and Pinot Meunier) during pressing that the Champagne producer decides not to remove by any decolorizing techniques.
