Odor threshold value (OTV) (also aroma threshold value (ATV), Flavor threshold) is defined as the most minimal concentration of a substance that can be detected by a human nose. Some substances can be detected when their concentration is only few milligrams per 1000 tonnes, which is less than a drop in an Olympic swimming pool. Odor threshold ...
Triethylamine is the chemical compound with the formula N(CH 2 CH 3) 3, commonly abbreviated Et 3 N. Like triethanolamine and tetraethylammonium , it is often abbreviated TEA. [ 8 ] [ 9 ] It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia .
In 2004, it was reported that the Israeli weapons research and development directorate had created a liquid stink bomb, dubbed the "skunk bomb", with an odor that lingers for five years on clothing. [4] It is a synthetic stink bomb based upon the chemistry of the spray that is emitted from the anal glands of the skunk. [4]
Key odorants can be identified by comparing the concentrations of the odorants with their respective flavor threshold. The resulting unit is the odor activity value (OAV). Every key odorant has an OAV higher than 1.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Triethanolamine is used primarily in making surfactants, such as for emulsifier.It is a common ingredient in formulations used for both industrial and consumer products. The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in wate
Deployment in Ni'lin during a demonstration in 2012. The material used is said to be an organic and non-toxic blend of baking powder, yeast, and other ingredients. [6] [7] Deriving its name from the animal of the same name which is known for its ability to spray a foul-smelling fluid, "Skunk" is dispersed as a form of yellow mist, fired from a water cannon, which leaves a powerful odor similar ...
A malodorant is a chemical compound whose extreme stench acts as a temporary incapacitant.It attacks the olfactory and/or trigeminal nerves of the person introduced to the chemical.
