Formulators or other product developers in the surface- and colloid business who are attending ECIS in Naples, don't miss this presentation by Marta Gubitosi! The topic being coacervate formation and deposition, using a green surfactant-polymer system. Main take-aways (for you who can't be there): There is a need to explore green coacervates, to follow market needs for formulated products and also expand the use of coacervates to food products. 😀 A green coacervate from our model system has been identified and characterised both in bulk and on a surface. 🥳 The knowledge and rules for traditional coacervates can be transferred to green coacervates. 🫣 #Ellipsometry and #Neutron #Reflectometry are both used to look at deposition, but the set-ups are different and that may translate to different observations/outcomes. Take care interpreting!!! Thursday Sept 7 at 15:00. #ECIS2023

Are you at ECIS (European #Colloid and #Interface Society meeting)? Do you wish you were? CR team member Marta Gubitosi is in Naples for ECIS 2023 for all of you who want to meet. Marta will also give a presentation on Thursday Sept 7 at 3pm. "Natural care products: a holistic study of structure and deposition of sustainable polymer and surfactant mixtures." The aim for us with the study was to see if the way we understand #coacervate forming systems today, can be transferred to and used also when new ingredients are used. Today, the theory is mainly based on data from traditional/synthetic chemistries. This is something we explore in several parallell projects also with clients and not only for coacervates. For a non-physical chemist it could maybe sound strange: why would the theory not hold? For us, it is important to know since we know how delicate the power of interactions is and the new systems are much less defined, have much larger inherent variability and this could challenge the way we deal with them. In the present study we also proved the strength of the CR perspectives: our ability to combine a discussion around both bulk and surface behaviour and our ability to critically look at the data. We see for example that the different set-ups for the two surface techniques must be acknowledged in ways that are important when designing these type of studies. We are happy we have been able to work on this subject and are grateful for the support provided by Tommy Nylander at Lund University, ISIS Neutron and Muon Source, Maria Öhman and Vinnova and of course the company Cosun Biobased Experts who provided their biobased polymer #Quatin for the study. The outcome? Yes, we understand this too! 😎 🧠 😎 The full data and slides? Listen to Marta on Thursday, reach out to us directly or wait for the publication to come! #coacervates #personalcare #foodscience #biobasedmaterials #SAXS #neutronreflectometry #ellipsometry
