DMD is the most selective non-chlorine bleaching agent known, and reacts with residual lignin in a way similar to chlorine and chlorine dioxide. In particular, DMD has the selectivity equivalent to chlorine dioxide in the bleaching of low-Kappa pulp, for example, a Kappa of less than 7 to 8 units.  2, fiche 1, Anglais, - dimethyldioxirane

Le DMD est l'agent de blanchiment non chloré le plus sélectif connu à ce jour. Il réagit avec la lignine résiduaire de façon similaire au chlore et au bioxyde de chlore. Le DMD possède une sélectivité équivalente à celle du dioxyde de chlore en ce qui concerne le blanchiment des pâtes de faibles indices kappa (moins de 7-8).  2, fiche 1, Français, - dim%C3%A9thyldioxirane

In effect, bleach solution is a whitening and disinfecting agent compose of water, sodium hypochlorite, sodium chloride, and soda, in a nonuniform manner. Solutions are marketed in two forms : concentrated bleach solution and diluted bleach solution in bottles. Poisoning from this product often occurs accidentally and particularly among children less than 5 years of age. Nonetheless, this poisoning may occur in adults, especially in the event the product is removed from its package or in a professional setting.  4, fiche 2, Anglais, - Javel%20water

Commonly the most dangerous chemical found in a household, bleach is an inorganic aqueous solution of 5. 25% sodium hypochlorite. Bleach is a clear to yellowish liquid with a distinct chlorine like odor. Often mistakenly referred to as "chlorine bleach" because of its strong smell, bleach does not release a considerable amount of chlorine gas during its normal mode of action.  11, fiche 2, Anglais, - Javel%20water

Javel water takes its name from the ancient village of Javel, now just one of Paris’ many neighbourhoods. In 1777, Count d’Artois founded the "Manufacture pour les Acides et Sels minéraux" in Javel, where the chemist Claude-Louis Berthollet worked. While searching for a method that would ease the work of washerwomen who had to whiten clothes by exposing them to sunlight, Berthollet came across a water solution that bleached cloth artificially, and he called it "eau de Javel."  12, fiche 2, Anglais, - Javel%20water

Claude Louis BERTHOLLET [...] étudia également les propriétés du chlore (acide marin déphlogistiqué), ce qui le conduisit à la découverte de l'eau de Javel appelée à l'époque «lessive de BERTHOLLET». On l'a nommée javel car c'est à Javel, un ancien village, aujourd'hui un quartier de Paris, qu'on la fabriqua.  6, fiche 2, Français, - eau%20de%20Javel

En 1820, le pharmacien Antoine Germain Labarraque étudie les qualités désinfectantes des dérivés chlorés et des hypochlorites de potassium et de sodium. Il met au point une solution de chlorure et d'hypochlorite de sodium qu'il appelle «liqueur de Labarraque». En 1900 on appelait eau de Javel l'hypochlorite de potassium, et eau de Labbaraque, l'hypochlorite de sodium. Plus tard, le procédé de fabrication a remplacé le potassium par le sodium, sans changement de nom.  3, fiche 2, Français, - eau%20de%20Javel

Preparation of bleach chemicals. All conventional bleaching chemicals can be produced from air, water and brine(NaCl solution) utilizing varying amounts of energy. Since the raw materials are cheap, it follows that manufacturing costs are mainly a function of how much energy is expended. Oxygen. Two systems are utilized for oxygen generation : cryogenic air separation and adsorption-based separation.... Cryogenic plants compress air and remove water, CO₂ and other impurities in a pretreatment system. The dry air is then cooled and liquified at cryogenic temperatures using turbo expanders and/or refrigeration systems. Finally, the liquified air is distilled to separate it into oxygen, nitrogen and other coproducts.  1, fiche 3, Anglais, - cryogenic%20air%20separation

Since the raw materials are cheap, it follows that manufacturing costs are mainly a function of how much energy is expended. Oxygen. Two systems are utilized for oxygen generation : cryogenic air separation and absorption-based separation.... The adsorption-based oxygen plant yields a gas product and is suitable only for onsite generation.... adsorption systems separate air at ambient temperatures using molecular sieve adsorbents. The adsorbent picks up nitrogen and other impurities at the system feed pressure, while the product oxygen passes straight through the bed. After the bed is saturated with nitrogen, it is regenerated by lowering the pressure to release the adsorbed components. Adsorption processes are cyclical, and multiple beds are used to maintain continuous oxygen production.  1, fiche 4, Anglais, - adsorption%2Dbased%20separation
