Bleaches

In chemistry, to bleach something generally means to whiten it or oxidize it. A bleach is a chemical that can produce these effects. Common chemical bleaches include sodium hypochlorite, or "chlorine bleach," and "oxygen bleach," which contains hydrogen peroxide or a peroxide-releasing compound (eg. sodium perborate, or sodium percarbonate). "Bleaching powder" is calcium hypochlorite. Bleaching can be a preliminary step in the process of dyeing. ...more on Wikipedia about "Bleach"

Calcium hypochlorite is a chemical compound with formula ( )2. It is widely used for water treatment and as a bleaching agent (bleaching powder). This chemical is considered to be relatively stable and has greater available chlorine than sodium hypochlorite (liquid bleach). It is manufactured using Calcium Process and Sodium Process. Calcium hypochlorite is not 100% soluble. For that reason it should preferably be used in soft to middle hard water. There are 2 types of Calcium hypochlorite viz. a dry and a hydrated quality. Latter quality is more safe in handling. For use in swimming pools Calcium hypochlorite can be used in combination with a stabiliser (Cyanuric acid). The stabiliser will prevent loss of chlorine because of UV radiation. ...more on Wikipedia about "Calcium hypochlorite"

Carbamide peroxide, also called urea peroxide, is an oxidising agent, consisting of hydrogen peroxide compounded with urea. The molecular formula is CH6N2O3, or CH4N2O.H2O. It is white crystalline material that releases oxygen in contact with water. ...more on Wikipedia about "Carbamide peroxide"

Chlorine dioxide is a reddish-yellow gas which is one of several known oxides of chlorine. Chlorine dioxide is relatively stable in the gas and liquid states, but can explode easily. Practically, it is never handled in its pure form. ...more on Wikipedia about "Chlorine dioxide"

Flour bleaching agent is a food additive added to flour in order to make it appear whiter (freshly milled flour is yellowish) and to oxidize the surfaces of the flour grains and help with developing of gluten. ...more on Wikipedia about "Flour bleaching agent"

Hydrogen peroxide (H2O2) is a clear liquid, slightly more viscous than water, that has strong oxidizing properties and is therefore a powerful bleaching agent that has found use as a disinfectant, as an oxidizer, and in rocketry (particularly in high concentrations as high test peroxide (HTP)) as a monopropellant and in bipropellant systems. ...more on Wikipedia about "Hydrogen peroxide"

The chemical compound nitrogen dioxide (NO2) is a red or orange/brown gas with a characteristic sharp, biting odor. It is considered an insidious deadly poison by inhalation. ...more on Wikipedia about "Nitrogen dioxide"

Sodium dithionite (aka Sodium Hydrosulfite) is a toxic, white crystalline powder with a weak sulforous odor. It is stable under most conditions, although it will decompose in hot water and in acid solutions. It can be produced by the following reaction: ...more on Wikipedia about "Sodium dithionite"

Sodium hypochlorite is a chemical compound with the formula NaClO. A solution of sodium hypochlorite is frequently used as a disinfectant and as a bleaching agent; indeed, often it is simply called "bleach", though other chemicals are sometimes given that name as well. ...more on Wikipedia about "Sodium hypochlorite"

Sodium perborate (PBS), also called perboric acid or metaborate peroxyhydrate, is a white, odorless, water-soluble chemical compound with chemical formula 3. It crystallizes as monohydrate or tetrahydrate. Sodium perborate is manufactured by reaction of sodium tetraborate, hydrogen peroxide, and sodium hydroxide. It is a skin irritant. ...more on Wikipedia about "Sodium perborate"

Sodium percarbonate (or sodium carbonate peroxyhydrate) is an addition compound of sodium carbonate and hydrogen peroxide. It is a white crystalline water-soluble chemical compound. When dissolved into water, its releases H2O2 and soda ash (sodium carbonate): ...more on Wikipedia about "Sodium percarbonate"
