Alcohol Ether Carboxylate Sodium (15EO)

Alcohol Ether Carboxylate AEC-5Na, also known as sodium fatty alcohol polyoxyethylene ether carboxylate, is a new type of anionic-nonionic surfactant. Its structure is very similar to that of soap, but the embedded EO chains give it the characteristics of both anionic and nonionic surfactants, allowing it to be used over a wide pH range. It exhibits excellent cleaning, emulsifying, and dispersing properties, as well as the ability to disperse calcium soaps; it possesses good foaming capacity and foam stability; it is resistant to acids, alkalis, hard water, high temperatures, oxidizing agents, and reducing agents; it has good compatibility and, in particular, does not interfere with the performance of cationic surfactants; it offers good solubilizing properties, making it suitable for formulating functional transparent products, and is readily biodegradable.

Product Features

Specification and Model: AEC-15Na 
Properties: 
1. AEC-15Na, an alcohol ether carboxylate, is a new type of multifunctional anionic surfactant. Its chemical structural formula is: R-(OCH₂CH₂)nOCH₂COONa(H), where R represents a C12–14 natural fatty alcohol and n = 15. Its lipophilic and anionic groups are identical to those of coconut oil acid soap, and the embedded EO chains give it the characteristics of both anionic and nonionic surfactants. 
2. Compared to the ester bonds in sodium fatty alcohol polyoxyethylene ether sulfates, the anionic group CH₂COONa in AEC-15 is linked to the EO chain via a structurally stable ether bond. This bond is resistant to hydrolysis even in the presence of strong acids or strong bases, greatly enhancing stability and allowing for use under more severe conditions. 
3. The embedded 15-EO chain is longer than the EO chains in AEC-3 and AEC-9, resulting in better resistance to electrolytes (i.e., salt tolerance). It has a higher surface tension than those two compounds and slightly lower penetrability. 
Application 
1. Used in household detergent formulations to improve the mildness of soap-based products, enhance their dispersing ability, and enable fatty acid soaps to form stable micelles in hard water. 
2. Stable against strong alkalis, chlorine, and hydrogen peroxide; suitable for cleaning under alkaline and bleaching conditions. 
Used for cleaning high-end fabrics or raw materials such as raw wool, silk, and velvet, it performs far better than corresponding alcohols and phenolic ethers and provides superior softness. 
3. Used as an emulsifying and viscosity-reducing agent for heavy oils under high-temperature, high-salt conditions; it offers high viscosity reduction and easy demulsification. 
4. When formulated with other surfactants or additives as an oil displacement agent under high-temperature, high-salt conditions, the high-temperature resistance of alcohol ether carboxylate allows it to serve as the primary surfactant in steam flooding. It significantly reduces oil-water interfacial tension, enhances crude oil recovery, and prevents wax precipitation. 
III. Scope of Application 
Suitable for household detergents, industrial cleaners, and phosphate-free detergents; Used in the textile industry for processes such as scouring, mercerizing, bleaching, softening, and dyeing; applied as an emulsifier and viscosity reducer resistant to high temperatures and high-concentration electrolytes in tertiary oil recovery and oil transportation to improve crude oil recovery rates and prevent wax precipitation; used in the paper industry for deinking waste paper and in softener formulations; used in the leather industry as a component of degreasing agents, etc.
