How to Choose the Right Desiccant for Your Product

Packaging is one of the primary concerns when manufacturing pharmaceutical drugs. You’d have to be especially careful when choosing a desiccant or sorbet for your product. Desiccants are a crucial part of pharmaceutical packaging as they help prevent damage through humidity and moisture and extend the life span of the drugs.

While the closure and cap mechanism of the bottled packaging of any drug will physically protect it from damage, the quality, type, and quantity of the sorbet used in the packaging also play a crucial role in maintaining the quality of the medicine for the consumer. If you use a low-quality desiccant, you might end up affecting the efficacy of your drugs.

But how do you choose the right type of desiccant for your products? Here are some tips:

Performance Level

The properties of moisture adsorption for different silica gel and molecular sieves diffeR. While molecular sieve offers great adsorptive capacity for lower humidity levels, silica gel performs quite poorly in an atmosphere with low humidity. Both desiccants, however, have almost the same moisture retention range at a room temperature of 25°C and a humidity level of 40%.

When should you use silica gel?

Silica gel is most suited for products with a stable temperature in the storage and a high relative humidity level. With its non-toxic, inert, and very stable properties, silica gel has become a popular choice as a desiccant for many pharmaceutical companies.

When should you use a molecular sieve?

While molecular sieve is a lot more rapid and aggressive in terms of moisture adsorption, this desiccant performs better for products that need instant protection from the moisture in their environment.

This sorbet is also very stable for a more extensive temperature range while maintaining its high properties of moisture retention. However, you should be cautious when choosing the proper dosage when using products with strict RH requirements.

Choosing the Right Desiccant Range

While selecting the perfect adsorbent for your product, it’s also important to go for the right product with the right desiccation range, as each range serves a different purpose. For instance, when choosing molecular sieves, there are several variants you can choose from, including 4A, 3A, and 13X. Type 4A is the most popular choice in the pharmaceutical industry.

At Sorbead India, we understand how essential it is to use the right desiccant for your products. That’s why our team offers a variety of desiccants developed for several different applications. The two most used are molecular sieve and silica. We also offer active alumina, silica gel orange crystals, moisture-free packaging solutions, and more.
