POEA is toxic to aquatic species like fish and amphibians. Like other surfactants, it can affect membrane transport and can often act as a general narcotic. [3] In laboratory experiments POEA has a half-life in soils of less than 7 days. Washout from soil is assumed to be minimal, and the estimated half-life in bodies of water would be about 2 ...
Surfactant molecules have either one tail or two; those with two tails are said to be double-chained. [4] Surfactant classification according to the composition of their head: non-ionic, anionic, cationic, amphoteric. Most commonly, surfactants are classified according to polar head group. A non-ionic surfactant has no charged groups in its ...
Griffin's method for non-ionic surfactants as described in 1954 works as follows: = / where is the molecular mass of the hydrophilic portion of the molecule, and M is the molecular mass of the whole molecule, giving a result on a scale of 0 to 20. An HLB value of 0 corresponds to a completely lipophilic/hydrophobic molecule, and a value of 20 ...
This means that the surfactant adsorbs at low surfactant concentrations with its head-group contacting the surface. Depending on the type of head-group and surface, the attraction will have a short-range contribution for both non-ionic and ionic surfactants. Ionic surfactants will also experience a generic electrostatic interaction.
[19] [20] Many products that contain nonylphenol have "down-the-drain" applications, such as laundry and dish soap, so the contaminants are frequently introduced into the water supply. In sewage treatment plants, nonylphenol ethoxylate degrades into nonylphenol, which is found in river water and sediments as well as soil and groundwater. [ 21 ]

Gluten-Free Mac & Cheese. $3.69. Good news for gluten-intolerant folks. Trader Joe's gluten-free mac is no longer "soupy and tasteless" thanks to a much-improved recipe, one commenter writes.
Mineral oil is the most used insecticide, both in acrage and in volume. 34,508,857 pounds (15,652,972 kg) of mineral oil was sprayed on 4,543,066 acres (about 1.8 million hectares). 1 to 4% solutions in water are sprayed, which is hundreds of times more than modern synthetic insecticides. Mineral oil is correspondingly cheaper.
