When Moisture Is Too Low, Capsules Fail

Silica gel can over-dry HPMC capsules and affect probiotic stability. de:hum is a paper, two-way desiccant designed to help maintain the right RH balance.


  1. Overlooked packaging risk
    • Desiccants are often used only to remove moisture.
    • For sensitive products, however, they can also make the environment too dry.
    • This can create a hidden packaging risk that is easy to miss.

  2. HPMC capsule stability
    • HPMC capsules require a controlled humidity range.
    • If the environment becomes too dry, the capsule shell may turn brittle.
    • This increases the risk of breakage and long-term stability loss.

  3. Probiotic viability
    • Probiotics are highly sensitive to packaging humidity.
    • Excessive drying can reduce viability during shelf life.
    • This may directly affect product quality and performance.

  4. Regulatory and sustainability pressure
    • Packaging is no longer evaluated only by moisture control.
    • Biodegradability, lifecycle impact, and ESG compliance are becoming more important.
    • Desiccant choice is now part of a broader compliance discussion.

  5. de:hum positioning
    • de:hum is a two-way, paper-based desiccant.
    • It is designed to maintain a stable relative humidity instead of absorbing moisture aggressively.
    • The goal is to support both product stability and sustainability.
