N,N-Diethyl-meta-toluamide, also called diethyltoluamide or DEET ( / diːt /, from DET, the initials of di- + ethyl + toluamide), [1] [2] is the oldest, one of the most effective and most common active ingredient in commercial insect repellents. It is a slightly yellow oil intended to be applied to the skin or to clothing and provides ...
Deltamethrin is a pyrethroid ester insecticide. Deltamethrin plays a key role in controlling malaria vectors, and is used in the manufacture of long-lasting insecticidal mosquito nets; however, resistance of mosquitos and bed bugs to deltamethrin has seen a widespread increase. Deltamethrin is toxic to aquatic life, particularly fish.
Chart. The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
In 1945, DDT was made available to farmers as an agricultural insecticide and played a role in the elimination of malaria in Europe and North America. Despite concerns emerging in the scientific community, and lack of research, the FDA considered it safe up to 7 parts per million in food. There was a large economic incentive to push DDT into ...
With the use of Picaridin, this repellent is safe to use on the whole fam. The bug spray is often found on "Best of" lists just like this one for its reputation of being a tough spray without DEET ...
m -Toluic acid. m. -Toluic acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) m-Toluic acid, ( IUPAC: 3-methylbenzoic acid ), is an aromatic carboxylic acid, with formula (CH 3 )C 6 H 4 (COOH). It is an isomer of p -toluic acid and o -toluic acid .
Infobox references. p-Menthane-3,8-diol, also known as para-menthane-3,8-diol, PMD, or menthoglycol, is an organic compound classified as a diol and a terpenoid. It is colorless. Its name reflects the hydrocarbon backbone, which is that of p -menthane. A total of eight stereoisomers are possible, based on the three stereocenters of the ring.
Fundamentally, the difference between these two types of fibers relates to how the fiber reacts with water. “Soluble fibers can dissolve in water and insoluble fibers do not dissolve in water ...
