Gelatin: The Essential Ingredient in Pharma


Gelatin, a protein derived from collagen in animal connective tissues, like skin, bones, and ligaments, exhibits unique characteristics determined by the amino acid sequence of its collagen source. When sourced from type I collagen, gelatin forms a triple helix structure, allowing it to exhibit properties such as gelling or maintaining a liquid state. This substance, typically obtained from pigs or cows, undergoes processing to result in a colorless, odorless, and tasteless product.

What’s so unique about gelatin in pharma?

Gelatin finds application as a coating agent for tablets and capsules. This enhances their appearance, swallowability, and stability. Gelatin coatings provide a smooth and glossy finish, safeguarding the medication from environmental factors like moisture and light.

How does gelatin meet consumer needs?

Gelatin is a safe and virtually non-allergenic ingredient that is universally tolerated by the human body. Therefore, it can be used in different medical applications. it has excellent solubility, dissolving rapidly in the stomach and this allows a fast release of the active content of the oral drug form while masking its odor and taste.

How does gelatin meet pharma production needs?

When used in capsules, gelatin provides an effective means of protecting the filling from light, atmospheric oxygen, contamination and microbial growth. Gelatin also meets the viscosity requirements for capsule production. It is available in a wide range of viscosities, which means a tailor-made solution that is based on the process requirements can be offered to the capsule producers.

Its thermoreversability (the ability to move from liquid and solid state and back to liquid without losing its gel strength), plays an important role in the production process of gelatin capsules. Thanks to this unique property:

  • Soft gelatin capsules can be effectively sealed after being filled with an active ingredient
  • In case of any deviations during hard capsule production, the thermoreversability of gelatin allows in-process adjustments

An additional benefit of gelatin in these applications is its ability to work on a broad range of pHs without the use of salts, ions, or additives.
