2. Stain removal - Wikipedia

   en.wikipedia.org/wiki/Stain_removal

   Another factor in stain removal is the fact that stains can sometimes comprise two separate staining agents, which require separate forms of removal. A machine oil stain could also contain traces of metal, for example. [1] Also of concern is the color of the material that is stained. Some stain removal agents will not only dissolve the stain ...

3. Chemistry of ascorbic acid - Wikipedia

   en.wikipedia.org/wiki/Chemistry_of_ascorbic_acid

   Ascorbic acid is easily oxidized and so is used as a reductant in photographic developer solutions (among others) and as a preservative. [citation needed] In fluorescence microscopy and related fluorescence-based techniques, ascorbic acid can be used as an antioxidant to increase fluorescent signal and chemically retard dye photobleaching. [19]

4. Photographic developer - Wikipedia

   en.wikipedia.org/wiki/Photographic_developer

   DD-X, HC-110, TMax developer, and PQ Universal developer are a few common film developers that use Dimezone as a developing agent. Dimezone is acutely toxic and an irritant. Hydroquinone can also be toxic to the human operator as well as environment; some modern developers replace it with ascorbic acid, or vitamin C. This, however, suffers from ...

5. Detergent enzymes - Wikipedia

   en.wikipedia.org/wiki/Detergent_enzymes

   For stain removal, conventional household washing machines use heated water, as this increases the solubility of stains. However, heating the water to the required temperature uses a considerable amount of energy; energy usage can be reduced by using detergent enzymes which perform well in cold water, allowing low-temperature washes and ...

6. Erythorbic acid - Wikipedia

   en.wikipedia.org/wiki/Erythorbic_acid

   Erythorbic acid is very easily produced by fermentation, being obtainable in just one step compared to ascorbic acid's two. A number of Penicillium naturally produce this chemical from glucose. This is the original process developed in the 1960s, but it has low volumetric efficiency and glucose yield compared to the modern method.
