The Important Role Desiccant Canisters Play in the Pharmaceutical Industry

In the pharmaceutical sector, packaging with desiccant canisters plays a crucial role. Most pharmaceutical and nutraceutical packaging companies generally opt for desiccant canisters, whether dental, herbal, diagnostic or veterinary. During the packaging process, the canisters are inserted into the bottles and containers, to ensure that the product is not affected by moisture, mildew and micro-organisms. 

The presence of moisture in the pharma bottles and containers adversely affects the medicines' quality and efficacy. In some cases, moisture can also cause irreversible chemical and physical changes and be poisonous. Thus, this is the reason why most pharmaceutical packaging companies prefer to use desiccant canisters. They protect the medicines from excess moisture and humidity reactions.

Why only desiccant canisters? The canisters have a high capacity and speed for adsorbing moisture and preventing humidity. Therefore, just because of this feature, they have been the best option for medicines for the past few years. 

The desiccant canisters are small and cylindrical shaped, stuffed with highly active drying agents. The unique design of the canister allows it to insert in a smaller space. They have tiny holes, through which the moisture inside the bottles and containers is adsorbed. Canisters can be used continuously with packed pharmaceutical products.

Pharma desiccants: how to use and what they do?

Pharma desiccants are majorly used in the pharmaceutical and nutraceutical industries. The desiccants play a crucial role in the packaging of pharma products. They effectively absorb the extra moisture inside the closed containers and keep the products dry. 

The desiccants come packed in small white packets inside the containers. They absorb moisture, maintain the product's quality, and extend its shelf life. The packets always have strict instructions: "Do not eat." Consumers should always follow this for their safety. 

Desiccants are commonly found in products, from shoeboxes to medicine bottles. These small packets are filled with a wide range of substances like silica gel, activated carbon, molecular sieves, and clay. Within these, silica gel desiccants are most commonly used and preferred by the pharma industries. 

What do they do?

In the pharma industry, desiccants are used for dental, diagnostic, herbal, nutritional, and even veterinary packaging. While packaging, the desiccants are inserted into the containers. This ensures that moisture doesn't impact the products.

The desiccants are commonly used to keep the products dry and stable. They absorb moisture from the air and even reduce the humidity on the surface of the sealed containers. It is very important to control moisture from pharmaceutical products because moisture can spoil the medicines, but also, in many cases, it can bring irreversible physical and chemical changes. Thus, because of the same reason, many pharmaceutical industries have started using pharma desiccants to get prevention from moisture and humidity. These are usually inserted in the form of canisters into the packaging lines to ensure that the medicines and other pharma products are not affected by moisture, mildew, and mould. 

How are the pharma desiccants used?

By maintaining the dryness and the quality of the products, the desiccants extend the shelf life and efficacy of pharmaceutical and nutraceutical products by preventing moisture damage. 

Desiccants work on the principle of adsorbing moisture from the air. It is known to be an agent that works on the mechanism of multiple adsorption layers, attracting the thin layers of moisture molecules from the air to the desiccant surfaces. It avoids chemical reactions with water and other dissolving chemicals. Many manufacturers use desiccants to prevent chemical hydrates from forming in the chemical industry. The desiccants also remove the moisture from the gas streams and solvents. 

These highly effective desiccants are most commonly used for products that can be damaged due to moisture. If moisture is trapped for a long time, it can cause the degradation of materials like electronics, food, clothing, and medicines. For this reason, desiccants are used during the packaging and storage of products. 

The desiccants packs contain small interconnected channels that open into pores on the surface that can absorb moisture from the product without altering their structure. The higher the moisture content, the higher the adsorption capacity. 

Utility of desiccant products:

  • Transportation of goods: The desiccants are very important for the packaging process while shipping products. These work like drying agents. 
  • Activated carbon desiccants: Carbon is always appreciated for extracting impurities from the air and leaves the atmosphere clean and hygienic. It also eliminates the foul smell from the enclosed areas. E.g., garages, basements, etc. 
  • Natural desiccants: The most commonly used natural desiccant is rice, used in commercial areas and to protect domestic goods. 
  • Preserve chemicals: desiccants are effectively used for storing the chemicals. The desiccants absorb the moisture and keep them dry. Few chemicals can form compounds when they come in contact with moisture. 

Few important factors to keep in mind before selecting a desiccant:

  • Type of container or package for the pharma products
  • The volume of the containers
  • The rate of absorption required
  • The climate
  • Cost-effectiveness of the desiccants
  • RH levels

Keep a Check on Your Store's Environment with Humidity Indicating Cards

Moisture is the biggest enemy of any sensitive product, like metal or electronic items. So, to ensure the products safety of the products, it is important to check the atmospheric conditions of the place where the product has to be stored. This is not only the best rather the cheapest way to know about the atmospheric humidity. Moisture is not the only time when the product has moisture danger. Even while transporting, any item can easily come in contact with atmospheric moisture, and many lose their originality. There are various products in the market which help to absorb moisture from the environment. But how may someone know which desiccant to use in different humidity situations? Check the atmospheric humidity with humidity indicator cards and then use the appropriate desiccant. 

Now, the question arises what are the indicator cards made up of, which makes them so efficient that they can analyze the amount of humidity in the atmosphere. The cards have a layer of cobalt chloride solution mixed carefully to change their colour from blue to various shades of magenta, red to pink. These cards are not made to indicate the exact amount of moisture in the environment. Still, they can efficiently tell the range of maximum possibility of humidity present in the container. For example, if a card indicates 10%- 60% of moisture if the dots' colours are deep blue, then you can be sure that the humidity is below 10%. It is very important for many products that the humidity level stays below 40% because the basic corrosion or rusting activity will never happen in this range.  

These humidity indicating cards are used for various purposes like storing your wedding dress heirloom, electronic items, computer products, old photographs, personal items and many more. Apart from this, it is also used to store optical instruments, bilk packaging and preserve sensitive components. It is also used in bulk to pack dry products like various semiconductors and electronic items. The advantage of using this humidity indicator card is that it is very easy and a fast moisture monitoring tool. If required, it can also be customized. There are two types of humidity indicating cards cobalt-free cards and cobalt cards. Both people mostly use cobalt cards because of their moisture indicating technique is more appropriate and accurate.
