Liquid bleach, often called just bleach, is a common chemical household product that consists of a dilute solution of sodium hypochlorite (NaClO) and other secondary ingredients. It is a chlorine releasing bleaching agent widely used to whiten clothes and remove stains, as a disinfectant to kill germs , and for several other uses.
"Bleach bypass", as used in this context, was first used in Kon Ichikawa's film Her Brother (1960). Kazuo Miyagawa, as Daiei Film's cameraman, invented bleach bypass for Ichikawa's film, [2] [3] [4] inspired by the color rendition in the original release of Moby-Dick (1956), printed using dye-transfer Technicolor, and was achieved through the use of an additional black-and-white overlay.
[47] [48] It may be made by diluting household bleach as appropriate (normally 1 part bleach to 9 parts water). [49] Such solutions have been demonstrated to inactivate both C. difficile [47] and HPV. [50] "Weak chlorine solution" is a 0.05% solution of hypochlorite used for washing hands, but is normally prepared with calcium hypochlorite ...
Calcium hypochlorite is an inorganic compound with chemical formula Ca(Cl O) 2, also written as Ca(OCl) 2.It is a white solid, although commercial samples appear yellow. It strongly smells of chlorine, owing to its slow decomposition in moist air.
The OSHA-allowable time-weighted average concentration over eight hours is 10 ppm, [30] almost 140 times higher; The OSHA highest allowable peak concentration (5-minute exposure for five minutes in 4 hours) is 200 ppm, [ 30 ] twice as high as the reported highest peak level (from the headspace of a bottle of a sample of bleach plus detergent).
Bleach activators are compounds that allow a lower washing temperature than would be required otherwise to achieve the full activity of bleaching agents in the wash liquor. Bleaching agents, usually peroxides, are usually sufficiently active only from 60 °C on. With bleach activators, this activity can already be achieved at lower temperatures.
In time-lapse photography, the camera records images at a specific slow interval such as one frame every thirty seconds (1 ⁄ 30 fps). The shutter will be open for some portion of that time. In short exposure time-lapse the film is exposed to light for a normal exposure time over an abnormal frame interval.
