Rheology dictates how a product behaves in the bottle and on the skin. Advanced thickeners do more than increase viscosity; they provide shear-thinning (pseudoplastic) properties. This ensures a cream stays thick in its jar but flows effortlessly when rubbed onto the skin. Formulators utilize synthetic polymers like Carbomers alongside natural cross-linked polysaccharides (e.g., Sclerotium Gum, Xanthan Gum) to create robust, non-tacky polymer networks. 2.
