Ethoxylation. In organic chemistry, ethoxylation is a chemical reaction in which ethylene oxide (C2H4O) adds to a substrate. It is the most widely practiced alkoxylation, which involves the addition of epoxides to substrates. In the usual application, alcohols and phenols are converted into R (OC2H4)nOH, where n ranges from 1 to 10.
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).

C12-15 pareth-12 (INCI name) is an emulsifier and surfactant commonly used in cosmetics formulations. It is a polyethylene glycol ether formed by combining synthetic C 12 –C 15 fatty alcohols with 12 moles of ethylene oxide. According to the INCI, "the term Pareth applies to ethoxylated paraffinic alcohols containing both even- and odd-carbon ...
The word "surfactant" is a blendof surface-active agent,[1]coined in 1950 .[2] As they consist of a water-repellent and a water-attracting part, they enable water and oil to mix; they can form foam and facilitate the detachment of dirt. Surfactants are among the most widespread and commercially important chemicals.
Fatty alcohol. Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils. The precise chain length varies with the source. [1][2] Some commercially important fatty alcohols are lauryl ...

Kolliphor EL is a synthetic, nonionic surfactant used to stabilize emulsions of nonpolar materials in water. Kolliphor EL is an excipient or additive in drugs. Therapeutically, modern drugs are rarely given in a pure chemical state, so most active ingredients are combined with excipients or additives such as Kolliphor EL. [2]
Dodecanol / ˈ d oʊ ˈ d ɛ k ɑː n ɒ l /, or lauryl alcohol, is an organic compound produced industrially from palm kernel oil or coconut oil. It is a fatty alcohol . Sulfate esters of lauryl alcohol, especially sodium lauryl sulfate , are very widely used as surfactants .
