Abstract
Processes for forming alkyl alkoxylated sulfate anionic surfactant containing concentrated surfactant blends having reduced levels of dioxane by-product while still providing good stability, grease cleaning and sudsing, include first forming an alkyl alkoxylated alcohol stream in which the alkyl alkoxylated alcohol stream includes at least two different alkyl alkoxylated alcohols, which differ in degree of alkoxylation by no more than 0.5, and then sulfating and neutralizing the alkyl alkoxylated alcohol stream to form the alkyl alkoxylated sulfate anionic surfactant.
