The major source of chemical bleaching is Hydrogen peroxide H 2 O 2 that contains a single bond, (–O–O–). When this breaks down it gives rise to very reactive oxygen specie, which is the active agent of the bleach. Around sixty percent of the world Hydrogen peroxide is used in chemical bleaching of textiles and wood pulp. [31]
Typical bleach activators are essentially N- and O-acyl compounds that form peroxyacids upon perhydrolysis (meaning hydrolysis by hydrogen peroxide from the bleach, persalts). For example, TAED produces in the wash liquor bleach-active peroxyacetic acid or from DOBA peroxydodecanoic acid. In all cases, the activator is chemically reacted ...
A peroxide-based bleach or simply peroxide bleach is any bleach product that is based on the peroxide chemical group, namely two oxygen atoms connected by a single bond, (–O–O–). This bond is fairly weak and is often broken in chemical reactions of peroxides, giving rise to very reactive oxygen species, which are the active agents of the ...
Oxygen bleach is also called color-safe bleach, non-chlorine bleach, or oxygenated bleach. Its active ingredient is typically hydrogen peroxide, although some formulas contain sodium percarbonate ...
Hydrogen peroxide is an anti-fungal and anti bacterial solution that eliminates mold on a wide variety of surfaces. Just spray the undiluted solution directly onto the mold and let it sit for 10 ...
Compared to TAED, which is the predominant bleach activator used in Europe, NOBS is efficient at much lower temperatures. At 20 °C NOBS is 100 times more soluble than TAED in water. [ 5 ] When attacked by the perhydroxyl anion (from hydrogen peroxide), NOBS forms peroxynonanoic acid (a peroxy acid ) and releases the leaving group sodium 4 ...
Hydrogen peroxide (H 2 O 2). It is used, for example, to bleach wood pulp and hair or to prepare other bleaching agents like perborates, percarbonates, peracids, etc. Sodium percarbonate (Na 2 H 3 CO 6), an adduct of hydrogen peroxide and sodium carbonate ("soda ash" or "washing soda", Na 2 CO 3).
A hypochlorite bleach can react violently with hydrogen peroxide and produce oxygen gas: H 2 O 2 (aq) + NaOCl (aq) → NaCl (aq) + H 2 O(l) + O 2 (g) A 2008 study indicated that sodium hypochlorite and organic chemicals (e.g., surfactants, fragrances) contained in several household cleaning products can react to generate chlorinated volatile ...
