Thickeners, as the name suggests, increase viscosity, giving liquids a certain thickness to create a uniform and stable system, enhancing suspension.
Thickeners are the backbone and essential foundation of various cosmetic formulations, crucial for a product's appearance, rheological properties, stability, and skin feel. By selecting commonly used and representative thickeners, preparing different concentrations of aqueous solutions, and testing their viscosity, pH, and other physical and chemical properties, we can conduct sensory evaluations on appearance, transparency, and multiple skin feel indicators during and after use. This leads to the identification of 16 common thickeners found in face masks.
Ladies, check if any of these ingredients are in the face masks you use! If you know of other thickeners, feel free to comment and share!
