Which type of capsule is known for showing better stability at higher temperatures?

Vegan capsules, often made from hydroxypropyl methylcellulose (HPMC) or similar plant-derived materials, are recognized for their superior stability at higher temperatures compared to traditional gelatin capsules. This stability arises from the inherent thermal resistance of the polymers used in vegan capsules, which do not melt or deform as easily when exposed to elevated temperatures.

Gelatin capsules, made from animal-derived gelatin, can become less stable in heat, leading to potential deformation and affecting the integrity of the capsule. Hard capsules, typically made from gelatin or other materials, also face similar thermal limitations, while soft capsules often contain liquid fills that can be sensitive to heat, further compromising their stability.

As a result, vegan capsules are preferred for formulations that may be exposed to higher temperature conditions, ensuring the active ingredients remain protected and effective.
