Pullulan

Pullulan (CAS 9057-02-7), also designated E1204 in food applications, is a naturally fermented polysaccharide produced from starch by the fungus Aureobasidium pullulans. It functions as a film-former, binder, and moisture-retention agent across food, pharmaceutical, and personal care manufacturing.

In oral solid dosage manufacturing, pullulan is the primary material for producing thin, rapidly dissolving oral strips and hard capsule shells as a gelatin alternative. Food manufacturers use it to coat confectionery, nuts, and snack products.

This ingredient extends shelf life by forming an oxygen-barrier film that reduces oxidative degradation. In cosmetic formulations, it delivers a tightening, skin-smoothing film effect in serums and face masks, supporting texture and on-skin performance claims.

Tablet coating and granulation processes also use pullulan as a binder where clean-label or plant-based positioning is a commercial requirement. It is highly valued for its versatility and ability to meet diverse industrial needs.

Pullulan is supplied as a white to off-white free-flowing powder. Commercially recognized grades include PF 10, PF 20, and PF 30, which differ primarily in molecular weight and viscosity profile for specific applications.

Viscosity is a key selection criterion for determining film thickness and dissolution rate in final products. Food-grade and pharmaceutical-grade specifications are available to meet various global regulatory requirements.

The food-grade material is compliant with regulatory status in applicable markets. This ensures that manufacturers can maintain high safety and quality standards while utilizing this multifunctional polysaccharide in their production lines.
