One of the world’s largest producers of surfactants considers the time spent at ILL using neutrons, through SINE2020, invaluable for its R&D activities.
Stepan is one of the world’s largest producers of surfactants, with more than 1800 employees and 16 manufacturing locations worldwide. Stepan provides surfactants expertise for commercial and industrial applications – ranging from foaming agents for shampoo to emulsifiers for agricultural insecticides or agents for oil recovery.
In its quest for formulations tailored to customer requirements, the company needed to validate hypotheses developed on the microstructure of surfactants. Their questions could not all be answered using standard techniques.
Stepan’s chemists therefore decided to use small-angle neutron scattering (SANS) on an instrument at the Institut Laue-Langevin (ILL) in France. SANS can reveal the average size and distribution of particles. It also provides information on shape and chemical structure (from about 1 nm to 1 μm).
“The SANS measurements gave us indications on the self-assembly structure of our surfactants. We were able to distinguish between different structures, findings which challenged our knowledge to date. The time spent with the ILL scientist was invaluable.

The goal of the project is to offer a total of 40 feasibility studies per year (until September 2019). Applications are being accepted and will be reviewed continuously. The decision on the feasibility and the appropriate facility to conduct measurements will be announced no later than one month after receiving your request.
Preliminary consultations via SINE2020 Liaison Officers with scientific experts in your field.
Support in defining, preparing and performing experiments at the research facilities.
Assistance with data analysis and result interpretation.
Join Europe’s companies in benefiting from the information neutrons can provide you!
