Film-forming agent(s): "Ingredients that are typically found in hair-care products but are also widely used in skin-care products, particularly moisturizers. These range from PVP to acrylates, acrylamides, and copolymers. When applied they leave a pliable, cohesive, and continuous covering over the hair or skin. This film produces excellent water-binding properties and leaves a smooth feel on skin. Film-forming agents can be skin sensitizers for some individuals[1]."
