The primary biomass used for surfactant production usually is as follows: cellulose, lignin, starch, chitin, oil and fat and pine oleoresin(an exudate of pine trees) and so on.

The mechanical properties of films made from the suspensions of blended natural polysaccharides, cellulose and chitosan, are studied.

Chitin is the only one positively charged nature of the edible animals, cellulose is different from the normal diet food.
