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 ...
Alkyl polyglycosides (APGs) are a class of non-ionic surfactants widely used in a variety of cosmetic, household, and industrial applications. Biodegradable and plant-derived from sugars, these surfactants are usually derivatives of glucose and fatty alcohols. [1]
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.
Nonoxynol-9, sometimes abbreviated as N-9, is an organic compound that is used as a surfactant. It is a member of the nonoxynol family of nonionic surfactants. N-9 and related compounds are ingredients in various cleaning and cosmetic products. It is widely used in contraceptives for its spermicidal properties.
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.
