The anionic surfactants, among which are alkyl ether sulfates (AESs), are the most used class of surfactants in cleansing applications. The negatively charged head group of AESs is a sulfate moiety linked with a variable number of ethylene oxide units, i.e. a polyethylene glycol chain. The hydrophobic part of an AES is constituted by a linear alkyl chain of carbon atoms, generally obtained from natural fatty acids. Coconut oil fatty acids, including the sodium salts of coceth sulfate (CES) with chemical formula C_xH_y (OCH₂CH₂)_n OSO₃Na, are widely used as feedstock for AESs synthesis. CES is added to many cleaning products and detergents defined as non‐aggressive. Currently, no detailed structural information concerning the alkyl chain length x and, more importantly, the degree of ethoxylation n has been reported.

阴离子表面活性剂是烷基醚硫酸盐（AES），是清洁应用中使用最广泛的一类表面活性剂。AES的带负电荷的头基是与可变数目的环氧乙烷单元（即聚乙二醇链）连接的硫酸盐部分。AES的疏水部分由碳原子的线性烷基链组成，通常从天然脂肪酸获得。椰子油脂肪酸，包括化学式为C _x H _y（OCH ₂ CH ₂）_n OSO _3的硫酸椰子二钠（CES）的钠盐Na，被广泛用作AES合成的原料。CES被添加到许多定义为非腐蚀性的清洁产品和洗涤剂中。目前，没有关于烷基链长x，更重要的是，乙氧基化度n的详细结构信息的报道。
