      abstract     = {Nonionic ethylene oxide (EO)‐based surfactants are widely
                      employed in commercial applications and normally form
                      gel‐like liquid crystalline phases at higher
                      concentrations, rendering their handling under such
                      conditions difficult. By incorporating CO2 units in their
                      hydrophilic head groups, the consumption of the
                      petrochemical EO was reduced, and the tendency to form
                      liquid crystals was suppressed completely. This surprising
                      behavior was characterized by rheology and studied with
                      respect to its structural origin by means of small‐angle
                      neutron scattering (SANS). These experiments showed a
                      strongly reduced repulsive interaction between the micellar
                      aggregates, attributed to a reduced hydration and enhanced
                      interpenetration of the head groups owing to the presence of
                      the CO2 units. In addition, with increasing CO2 content the
                      surfactants became more efficient and effective with respect
                      to their surface activity. These findings are important
                      because the renewable resource CO2 is used, and the
                      CO2‐containing surfactants allow handling at very high
                      concentrations, an aspect of enormous practical importance.},
