3. Manufacturing processes
Non-ionic surfactants are obtained by two main processes.
-
Condensation
Esterification is the most important method, but transesterification and, less commonly, amide formation and glucosydation are also used. These reactions, as shown in the diagram below, lead to the elimination of water, low-molar-weight alcohols or hydrochloric acid.

Statistical and economic data
1. Production
Among the various classes of surfactants, non-ionic surfactants (NIS) now rank first in terms of both volume and value. Their consumption continues to grow due to their physico-chemical properties, the effects they are intended to achieve, and developments in formulation technologies.
In Europe, the total market for surfactants (expressed as 100% active ingredient)...
