A continuous process for the preparation of a surfactant, the process comprising the step of mixing a first component comprising a surfactant acid precursor with a second component comprising at least a molar equivalent amount of a neutralizing agent by using one or more static mixers wherein in that the neutralizing agent is added in one proportion.
A continuous process for the preparation of a surfactant, the process comprising the step of mixing a first component comprising an anionic surfactant acid precursor with a second component comprising a neutralizing agent selected from alkaline inorganic materials, alkaline earth inorganic materials, and mixtures thereof, wherein the molar ratio of the first to second component is from about 1:1 to about 1:1.5 by using one or more static mixers wherein the neutralizing agent is added in one proportion and wherein the pressure inside the static mixer is above about 300,000 Pa to attain a degree of neutralization of at least about 80% and a moisture content of the surfactant of less than about 20% wt.
