  2. 2,4-Dichlorophenoxyacetic acid - Wikipedia

    en.wikipedia.org/wiki/2,4-Dichlorophenoxyacetic_acid

    2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.

  3. Herbicide - Wikipedia

    en.wikipedia.org/wiki/Herbicide

    Surfactants alter the physical properties of the spray solution and the overall phytotoxicity of the herbicide, increasing translocation. Herbicide safeners enhance the selectivity by boosting herbicide resistance by the crop but allowing the herbicide to damage the weed. Selectivity is determined by the circumstances and technique of application.

  4. Microemulsion - Wikipedia

    en.wikipedia.org/wiki/Microemulsion

    Three components are the basic requirement to form a microemulsion: two immiscible liquids and a surfactant. The majority of microemulsions use oil and water as immiscible liquid pairs. If a cosurfactant is used, it may sometimes be represented at a fixed ratio to surfactant as a single component, and treated as a single "pseudo-component".

  5. Octenidine dihydrochloride - Wikipedia

    en.wikipedia.org/wiki/Octenidine_dihydrochloride

    Octenidine dihydrochloride is a cationic surfactant, with a gemini-surfactant structure, derived from 4-aminopyridine. It is active against Gram-positive and Gram-negative bacteria . Since 1987, it has been used primarily in Europe as an antiseptic prior to medical procedures, including on neonates.

  6. Emulsion polymerization - Wikipedia

    en.wikipedia.org/wiki/Emulsion_polymerization

    In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.

  7. Linear alkylbenzene - Wikipedia

    en.wikipedia.org/wiki/Linear_alkylbenzene

    Linear alkylbenzenes (sometimes also known as LABs) are a family of organic compounds with the formula C 6 H 5 C n H 2n+1.Typically, n lies between 10 and 16, although generally supplied as a tighter cut, such as C 12-C 15, C 12-C 13 and C 10-C 13, for detergent use. [1]

    In 2017, the ABC's current affairs program Four Corners reported that the storage and use of firefighting foams containing perfluorinated surfactants at Australian Defence Force facilities around Australia had contaminated nearby water resources. [105] In 2019, remediation efforts at RAAF Base Tindal and the adjacent town of Katherine were ...

  9. Emulsion stabilization using polyelectrolytes - Wikipedia

    en.wikipedia.org/wiki/Emulsion_stabilization...

    The difference depends upon the nature of the surfactant or polyelectrolyte in question. The hydrophilic pieces will attract the polar solvent, creating a water-in-oil emulsion and the hydrophobic pieces will attract the nonpolar solvent, creating an oil-in-water emulsion.
