Structures formed by rhamnolipids and polysaccharides in the presence of mono- and bi-valent salts

Abstract: Rheology modifiers are used to alter the viscosity of products in order to change their flow. In order to make more sustainable products, the traditionally used oil-derived polymers used to alter rheology can be replaced by polysaccharides. For the role of polysaccharides in formulation to be optimised, interactions between them and other formulation ingredients must be analysed, and factors such as natural structural variation must taken into account in such analysis. The aim of this study is to investigate the structures formed between the polysaccharide, xanthan gum, at different acetate/pyruvate ratios and rhamnolipids - a bio-derived, sustainable surfactant - in the presence of sodium and calcium chloride. Elucidating the interactions between these ingredients will allow the optimisation of their use in formulations for home and personal care products.
