Editing Hydrogen peroxide (section)

===Bleaching===
About 60% of the world's production of hydrogen peroxide is used for [[bleaching of wood pulp|pulp- and paper-bleaching]].<ref name="HageLienke">{{cite journal |vauthors = Hage R, Lienke A |title = Applications of transition-metal catalysts to textile and wood-pulp bleaching |journal = Angewandte Chemie |volume = 45 |issue = 2 |pages = 206–222 |date = December 2005 |pmid = 16342123 |doi = 10.1002/anie.200500525 |url = https://onlinelibrary.wiley.com/doi/10.1002/anie.200500525 |access-date = 14 February 2022 |url-status = live |archive-url = https://web.archive.org/web/20220125060924/https://onlinelibrary.wiley.com/doi/10.1002/anie.200500525 |archive-date = 25 January 2022}}</ref> The second major industrial application is the manufacture of [[sodium percarbonate]] and [[sodium perborate]], which are used as mild bleaches in [[laundry]] [[detergent]]s. A representative conversion is:
:{{chem2|Na2B4O7 + 4 H2O2 + 2 NaOH -> 2 Na2B2O4(OH)4 + H2O}}
Sodium percarbonate, which is an adduct of [[sodium carbonate]] and hydrogen peroxide, is the active ingredient in such laundry products as [[OxiClean]] and [[Tide (detergent)|Tide laundry detergent]]. When dissolved in water, it releases hydrogen peroxide and sodium carbonate.<ref name= jonesclark/> By themselves these bleaching agents are only effective at wash temperatures of {{convert|60|C}} or above and so, often are used in conjunction with [[bleach activator]]s, which facilitate cleaning at lower temperatures.

Hydrogen peroxide has also been used as a [[flour bleaching agent]] and a [[tooth whitening|tooth and bone whitening]] agent.
