Medical Use Desiccant
The Medical Industry Desiccants are moisture management products for mission critical applications. The Medical Industry Desiccants are used to protect from moisture sensitive medical equipment, pharmaceuticals, diagnostics, and devices while in transport, storage and/or use. They are designed to capture and hold on to ambient moisture vapor to prevent condensation, chemical degradation, loss of pharmaceutical potency, growth of microbes, and corrosion of metal components. The primary forms are: high-purity silica gel (which consistently comply with USP / EP), molecular sieves, where clay (desiccants are packaged in Tyvek® pouches or canisters intended for use in cleanroom applications). Having an understanding of regulatory practices to ensure compliance is critically important to maintain the integrity and sterility of the products .Some mission critical applications include: protecting moisture-sensitive medications and vaccines, in their vials or packaging; protecting humidity sensitive surgical and electronic medical devices during transport and storage; maintaining diagnostic reagents and test kits’ stability, accuracy or shelf-life; providing sterility for implantable devices. It is also highly regulated which involves different investigations, defined material specifications, functional safety and purity investigations, cleanliness and performance. Selecting the suitable type, capacity and style of desiccant is important to ensure integrity and shelf-life of medical products through the supply chain and ensure the functionality of life-saving medical products.
Industry Challenges
egulatory & Safety Compliance
- Meeting strict global regulations (FDA, EMA) for biocompatibility, safety (e.g., USP Class VI), and purity.
- Ensuring minimal leachables/extractables and comprehensive traceability.
- Proving safety for direct contact with drugs/devices, critical for all types (silica, montmorillonite, fiber, Ca/Mg chlorides).
Material Performance & Integrity
- Maintaining ultra-high material purity across all desiccant types to prevent product contamination.
- Ensuring compatibility with protected products (e.g., avoiding corrosion from chlorides like CaCl₂/MgCl₂, dusting from clays like attapulgite/montmorillonite).
- Preventing physical degradation (e.g., breakage, dusting) that could harm devices/drugs.
Packaging & Process Requirements
- Developing robust packaging (e.g., Tyvek® for silica gel, fiber) that withstands sterilization (gamma, ETO, e-beam) without failing.
- Minimizing linting/dust generation during handling and use (particularly relevant for clay desiccants vs. fiber).
- Ensuring packaging integrity maintains sterility barrier and desiccant function.
Validation & Performance Assurance
- Accurately calculating required desiccant capacity/correct type for diverse products and climate conditions.
- Demonstrating consistent and predictable adsorption performance across the product shelf life.
- Validating performance under real-world conditions with complex protocols.

FAQ
Packaging & Transportation Desiccant
Silica gel desiccants are necessary to protect products in transit and storage. Silica gel desiccants are packaged in breathable sachets or canisters, and manage humidity in shipping containers, cartons, and crates. Silica gel absorbs moisture in the ambient air, and prevents condensation, mold, metal corrosion, and damage to moisture sensitive materials. Silica gel is perfect for electronics, machinery, art, and paper products, to ensure items arrive in the right condition no matter what climate change may have occurred during the logistics of global transport.
Electronics Industry
Silica gel is well known for its moisture control properties in electronic manufacturing and storage. Proper protection of sensitive components is critical, especially in packaging of items such as circuit boards, semiconductors, or optical devices. By using silica gel in sealed packages, or sealed cabinets, electronics are kept in low-humidity environments. This reduces the risks of unforeseen damage to components from oxidation, electrical shorts, and performance failures of any kind. The properties of silica gel, non-corrosive, dust-free, and safe for direct contact with delicates parts, ensures safe shipping and handling from factoryels in an unopened condition.
Pharmaceutical Industry
Silica gel provides vital moisture prevention in medicine bottles, diagnostic kits and as a component of medical device packaging. Silica gel satisfies FDA and pharmacopeia requirements and protects tablets, capsules, and laboratory reagents from both moisture-driven degradation and elevated moisture levels. Importantly, silica gel acts to stabilize humidity levels in sealed environments extending shelf-life, sterility, and therapeutic effectiveness or viability. Silica gel packets not only work well to smooth out humidity changes, but they are also transparent which allows a visual inspection. Furthermore, cobalt-free silica gel packets pose no toxicity issues in deliberately sensitive applications.
