Surfactin is a cyclic lipopeptide, commonly used as an antibiotic for its capacity as a surfactant. [2] It is an amphiphile capable of withstanding hydrophilic and hydrophobic environments. The Gram-positive bacterial species Bacillus subtilis produces surfactin for its antibiotic effects against competitors. [ 3 ]
The word bulk is important because surfactants partition between the bulk and interface and CMC is independent of interface and is therefore a characteristic of the surfactant molecule. In most situations, such as surface tension measurements or conductivity measurements, the amount of surfactant at the interface is negligible compared to that ...
Polysorbate 20 is used by philatelists to remove stamps from envelopes and to remove residues from stamps, without harming the stamp itself. Polysorbate 20 is also used as wetting agent in rubber balers in the elastomer industry. Polysorbate 20 has been used as a shape directing agent to synthesize spheroidal magnetite nanoassemblies. [5]
HLB scale showing classification of surfactant function. The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipophilic portions of the surfactant molecule, as described by Griffin in 1949 [1] [2] and 1954. [3]
Triton X--100 (C 14 H 22 O(C 2 H 4 O) n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group.
Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone. [9]
Polysorbate 20 is also known as Tween 20, a commercial brand name. It is a common detergent used in many buffers for washing nitrocellulose membrane in western blotting and microtiter plate wells in ELISA assays. Tris is a buffer that maintains a pH of 7–9.2.
An unusually small crossbow bolt with a tapered "waist" shaft section and rear skirt compared to a 1 euro cent coin A bolt or quarrel is a dart -like projectile used by crossbows . [ 1 ] The word quarrel is from the Old French quarrel (> French carreau ) "square thing", [ 2 ] specialized use as quarrel d'arcbaleste (> carreau d'arbalète ...
