Gelation of oxidised cellulose nanofibrils with industrially relevant anionic surfactants

Abstract: This proposal aims to investigate the interaction of oxidised cellulose nanofibrils (OCNF) and anionic surfactants, such as sodium laureth sulphate (SLES) and sodium lauroyl sarcosinate (SLS ), in order to find new more environmentally friendly rheology modifiers for possible applications in personal care or agrochemicals. OCNF and anionic surfactants are both negatively charged species, hence nanofibrils and surfactant species experience strong electrostatic repulsions in solution, influencing the structural and rheological properties of the blend. Our earlier work has studied model surfactant sodium dodecylsulfate extensively, but SLS and SLES form stronger gels with OCNF. Here we aim to study the structures formed by these anionic species and OCNF in solution, to identify the interactions which lead to the observed improvement in gel properties.
