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 ...

Narrow-range ethoxylates (NREs) in chemistry are fatty alcohol polyglycol ethers with a narrow homolog distribution and are known nonionic surfactants.They can be produced industrially, for example, by the addition of ethylene oxide onto fatty alcohols in the presence of suitable catalysts (layer compounds which have been calcined or hydrophobized with fatty acids).

Hydrocarbon-based surfactants are an example group of amphiphilic compounds. Their polar region can be either ionic, or non-ionic. Some typical members of this group are: sodium dodecyl sulfate , benzalkonium chloride , cocamidopropyl betaine (zwitterionic), and 1-octanol (long-chain alcohol, non-ionic). [citation needed]
Polysorbate 20 (common commercial brand names include Kolliphor PS 20, [2] Scattics, Alkest TW 20, Tween 20, and Kotilen-20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan monolaurate.
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.
For example, food samples were found with concentrations ranging from 0.1 to 19.4 μg/kg in a diet survey in Germany and a daily intake for an adult were calculated to be 7.5 μg/day. [38] Another study calculated a daily intake for the more exposed group of infants in the range of 0.23-0.65 μg per kg bodyweight per day. [ 39 ]
