What Is Pullulan?
Pullulan is a water-soluble polysaccharide produced by the fermentation of starch using Aureobasidium pullulans. Chemically, it is composed of maltotriose units linked by α-1,6 glycosidic bonds, giving it a unique molecular structure and performance advantages over many other natural polymers.
- Chemical Type: Neutral polysaccharide
- Source: Microbial fermentation (starch-based, non-animal origin)
- Появление: Порошок от белого до почти белого цвета
- Taste & Odor: Neutral, tasteless, odorless
- Растворимость: Easily soluble in cold and hot water
Pullulan is widely recognized as a clean-label, non-GMO, и plant-based ingredient suitable for modern health-focused formulations.
Is Pullulan Safe?
Yes. Pullulan is considered extremely safe and is approved for use in food, pharmaceutical, and cosmetic applications in many countries and regions.
Safety Profile Highlights:
- Non-toxic and non-allergenic
- Non-carcinogenic
- Digestible and biocompatible
- Suitable for children and sensitive populations
- Approved as a food additive in many regions (often labeled as a dietary fiber or film-forming agent)
Because pullulan is not derived from animal sources and contains no gluten, it is ideal for vegan, vegetarian, halal, and kosher formulations.
Key Properties of Pullulan
Pullulan’s popularity comes from its unique combination of physical and functional properties:
- Excellent film-forming ability
Forms clear, strong, oxygen-impermeable films without plasticizers.
- High oxygen barrier performance
Superior to many synthetic polymers, making it ideal for food and pharmaceutical packaging.
- Good adhesion and binding properties
Useful as a tablet binder, coating material, and stabilizer.
- Water solubility and transparency
Easily dissolves in water and produces clear solutions.
- Biodegradable and environmentally friendly
Fully biodegradable, supporting sustainable material development.
IN Cosmetic Application
- Offers outstanding film formation and refreshing luxurious skin feel.
- Because of its excellent film formability, BLIT Chemical Pullulan could bring luxurious viscosity and be a good skin feeling adjustor in cosmetics, such as facial mask, essence, sun repair-cream, nail care and spray cosmetics.
- It also plays roles as oxygen impermeability in high-level cosmetics such as anti-age, anti-wrinkle products.
Heat Stability
| Group | Значение pH | Initial Viscosity | 80°C 1h | Degradation rate(%) | 80°C 2h | Degradation rate(%) |
| A group | 7.16 | 128cp | 124cp | 3.13% | 120cp | 6.25% |
| B group | 3.51 | 126cp | 122cp | 3.17% | 118cp | 6.35% |
| C group | 10.04 | 122cp | 116cp | 4.92% | 112cp | 8.20% |
BLIT Chemical Pullulan is remarkably stable under high temperature, and it has great stability within the pH range of 3.5-10.0.

Experimental Results
四个图片一组 2组
- Control group: The skin wrinkles re-appeared after 1.5h.
- Experimental group: A film was formed on the skin surface, and the wrinkles on the skin surface were completely covered. Pullulan could bring instant firming to the skin.
Anti-Pollution
Experimental Method
- Use activated carbon as air pollutants, spray the formula 10 cm away from the skin.
- Observe the adsorption of activated carbon in both groups.
- Rinse with flowing water for 30s, and observe the residue of activated carbon after washing.
Experimental Results
- Before wash: Control group, Experimental group
- After wash: Control group, Experimental group
- Conclusion: In the experimental group, air pollutants were more difficult to adsorb on the skin surface and stayed on the smooth film surface formed by pullulan. After washing, they are easy to be washed clean together with the Pullulan film. The control group adsorbed more activated carbon, and activated carbon remained in the skin wrinkles after washing.
IN Food Application
- Offers excellent adhesive and coating properties.
- Pullulan is a polysaccharide with high water solubility.
- Pullulan can strongly bind food materials due to its high adhesive and binding properties, which can be also applied in granulation and tableting.
- Pullulan also has excellent film forming and coating abilities that are simple to use for creating edible films and providing luster and preservative effects to the surface of food products.
Adhesive Property
Adhesiveness after drying (kg/cm²)
- Comparison among Pullulan, Phenol resin, Corn starch, Oxidised starch, Glue
- (Note: Pullulan shows superior adhesiveness based on the chart data)
Application in VC Candy
VC Content Loss During Long-Term Storage
| Storage Time (Months) | 0 | 3 | 9 | 12 |
| Group A (with Pullulan) | 1.6 | 1.6 | 1.5 | 1.5 |
| Group B (without Pullulan) | 1.6 | 1.4 | 1.3 | 1.2 |
- Store the candy with pullulan added as a gel-forming agent for 12 months, and the index shows no change.
- Candy without pullulan continues to lose VC during storage.
- According to the above charts, its preservation effect on fresh fruit is obvious. Besides, it is friendly to the environment with no pollution.
9. Application in Tablet
- Gum Arabic 2% + Pullulan 0.25%
- As a coating agent, pullulan is effective in protecting tablet completeness.
