HPMC & Pullulan Capsules, What are the Differences?

Source
Pullulan in capsules is made from corn starch fermentation, while HPMC is made from cotton fiber. Pullulan is completely natural, while HPMC is semi-synthetic.

Moisture
The moisture content of pullulan capsules is about 10%-13%, while the moisture content of HPMC capsules is 5%-8%. Because of the high moisture content of pullulan polysaccharide capsules, it is not suitable for filling moisture-sensitive materials and hygroscopic powders and liquids.

Price
The price of pullulan is roughly twice that of HPMC, which also causes the price of pullulan capsules to be much higher than the price of HPMC capsules. This is the main reason why many manufacturers do not choose it, despite its inherently superior properties.

Certificates
Both Pullulan and HPMC can meet vegetarian, religious, and some special requirements. They both have certificates including Vegetarian, Non-GMO, Halal, Kosher, TSE/BSE free, Gluten/Preservative Free and in addition, pullulan can obtain the organic certificate than HPMC. Because pullulan is 100% naturally fermented, while HPMC is produced through a chemical process.

Safety
There is no safety risk to our body for both pullulan and HPMC capsules. HPMC capsules are approved for use by many national FDA authorities. The source of pullulan capsules is purely natural ingredients without any added chemical or synthetic ingredients, which is safe and healthy for our bodies.

Allergens
Pullulan capsules and HPMC capsules are free of all the most common food allergens, including peanuts, nuts, eggs, milk (milk protein and lactose), fish, shellfish, soy, wheat, barley, sesame, and gluten.

Oxygen Transmission Rate
The oxygen permeability of pullulan capsules is approximately one 300th of the oxygen permeability of HPMC capsules, under the same conditions. The oxygen transfer rate of pullulan capsules is 0.4 cm3/m2-day, while the oxygen transfer rate of HPMC capsules is 127 cm3/m2-day. Therefore, pullulan capsules are the best choice for filling oxygen-sensitive materials.

Hygroscopicity
The hygroscopicity of HPMC capsules is much lower than that of pullulan capsules because of the presence of methoxy and hydroxypropyl in the structure of HPMC, which makes it difficult to form hydrogen bonds with water. However, its water-keeping property is similar to that of Pullulan.

Chemical Stability
Both pullulan and HPMC are inert, do not react with other substances, are quite stable, and are excellent raw materials for capsules.
