Eco-Formulation

In the objective to reduce chemical and carbon footprint in a product life cycle, Eco-Formulation is one crucial link in the pathway to deliver sustainable solutions with diverse basic building blocks.

With deep background in physical chemistry, our main interests lie in the formulation of surfactants, polymers and inorganic particles in aqueous or organic medium, and the surface/interface phenomena arising during their application in different fields.

The main role of this lab is to bring physical chemistry and formulation support to GBUs, as well as act as the interface between the UMI and the GBU labs, with the long-term mission to establish scientific excellence in physical chemistry to accompany sustainable growth of Solvay in AP.

The Eco-formulation lab is a 100% Solvay advanced lab and for now composed of 5 researchers. Four main activities are currently undergoing:

  • Seed treatment & evaluation workflow: High throughput Agro additives screening in living conditions
  • Green Toolbox & Bio-based surfactants formulation: develop new tools or concepts to achieve Eco-efficient formulations and identify new bio-based surfactants.
  • Pickering emulsion understanding: interfacial phenomena exploration and prediction for catalysis applications
  • Inorganic slurry formulation & optimization: Hybrid formulations

The world is being challenged by various issues among which agriculture seems take the lead. Global population has reached 7 billion and is still increasing very fast so offering enough food is the first priority of every country. Water, soil and seed are basic source used to produce every commercial crop today. Eco-formulation team is making scientific effort to answer challenge from agriculture. Natural polymer based products have been developed to reduce evaporation from farmland. Soil erosion has been studied and some products were invented to significantly decrease soil erosion. Seed booster agent was also successfully developed to increase yield and secure crops.

Green Tool Box

One database about bio-based surfactant including their structure, synthesis route, physico-chemical properties, application performance test. This tool is an excellent platform to identify potential new applications for biobased surfactants and allows a performance comparison of different chemistries.

Pickering Emulsions

We study very deeply pickering emulsions with original particles, in particular particles that bear catalytic sites and that could be used to carry out Pickering Interfacial Catalysis. This work involves not only the characterization of the particles themselves but also the study of the emulsions. We developed a strong know-how in studying unconventional oil / oil emulsion systems. Such studies support our goal to develop PIC systems capable of promoting the reaction of immiscible reagents without the use of solvents.
