pullulan could be used in cream skin care product

Pullulan is a natural water-soluble polysaccharide produced by Aureobasidium pullulans fermentation. Molecular weight 20 000 ~ 2 million, cas 9057-02-7. Because of its unique structure and properties, the polysaccharide has a wide application prospect in medicine, food, petroleum, chemical industry and other industries. Because it can be degraded and used by microorganisms in nature and will not cause environmental pollution, it is known as pollution-free plastics.

Pullulan has several excellent properties as follows: film-forming, solubility, gas barrier, non-toxicity, stability, lubricity and moisturizing, so that it can be used as film-forming agent, carrier, antioxidant, moisturizer and water binder in skin care products. can form an excellent natural barrier on the surface of the skin.

Film-forming agent

Pullulan is extremely soluble in water. Apply a thin and elastic hygroscopic film on the skin to produce a tight effect immediately. The film also has a certain tensile strength, which can stretch the skin and remove wrinkles when used in the cream. And cosmetics are easy to remove and easy to clean, which can effectively remove dead cells on the surface of the skin and deeply clean the skin.


Pullulan can dissolve quickly in cold water, and the solution is stable for a long time, and there is no “aging” phenomenon, so it is not easy to be affected by pH or various salts. This is beneficial to use in different cosmetic formulations and has good compatibility. Pullulan polysaccharides can cooperate with other polymer materials, such as carrageenan, starch and gelatin, etc. Pullulan polysaccharides can improve the gel strength and water holding capacity of carrageenan, and increase the gel temperature and melting temperature. Therefore, it can be used as a stable carrier of active ingredients, color and aroma of skin care products.


The pore size of the film formed by pullulan is nanometer, which can isolate PM2.5 contaminated particles. Isolate static electricity and dust. It can effectively protect the skin from external harm.

The air permeability of pullulan polysaccharide film is lower than that of other polymer films, and oxygen, nitrogen and carbon dioxide can not pass through at all, but it has higher moisture permeability. Therefore, pullulan is also antioxidant.

Skin tightening and smoothing

The application of pullulan in skin care brings immediate and temporary skin smoothing effect. The film it forms on the skin helps to smooth the surface and reduces the appearance of fine lines and wrinkles after application.
