Pullulan is a Newtonian fluid that offers excellent lubricity despite its low viscosity. Compared to ordinary polysaccharides, pullulan exhibits notable adhesive properties, allowing it to adhere easily to the skin's surface. It is also highly soluble in water, disperses well, absorbs moisture effectively, and is non-toxic. This makes pullulan suitable as an adhesive filler in cosmetics, providing similar benefits to hyaluronic acid but at a lower cost.

In addition to its adhesive qualities, pullulan has exceptional lubricity, which helps to isolate static electricity and dust while offering moisturizing effects. When added to cosmetics, it not only delivers a smooth feel to the skin but also helps protect against external damage.
