One subgroup comprises salts containing the sulfate ion (SO42-)linked via ionic bonds with any of various cations. Another subgroup of sulfates, the esters, are organic compounds in which sulfuric acid's hydrogen atoms are replaced by organic groups (e.g., methyl, ethyl, phenyl); a carbon atom in the organic group bonds to an oxygen atom, whose second bond is to the sulfur atom. (In sulfonates, a carbon atom bonds directly to the sulfur atom.)

硫酸盐是硫酸根离子(SO2-4)和任何阳离子的离子结合的无机化合物。而硫酸酯则是硫酸中的氢原子被有机基团(如甲基、乙基或苯基)取代而成的有机化合物,其中有机基团中的碳原子同氧原子结合,并同硫原子有二价结合(在磺酸盐中,碳原子同硫原子直接结合)。

The term usually refers to synthetic substances and excludes soaps. The characteristic features of a molecule of any detergent are a hydrophilic (water-attracting)end and a hydrophobic (oil-attracting)end. In ionic detergents, the hydrophilic property is conferred by the ionized part of the molecule. In nonionic detergents, hydrophilicity is based on the presence of multiple hydroxyl groups or other hydrophilic groups.

洗涤剂也往往用作乳化剂。洗涤剂通常不是指油脂皂化而得的肥皂,而是指一种合成物质。在水中洗涤剂的主要用途是洗杯、碟和衣服。任何一种洗涤剂都具有一个亲水端和一个疏水端。在离子洗涤剂中,亲水性是由分子的离子化部分而来。在非离子洗涤剂中,亲水性是基于多羟群和其它亲水残余物的存在而产生。
