When designing and packing pharmaceutical drugs, good packaging is a high priority when it comes to the sorbent or desiccant you use. Desiccants are an integral part of active packaging because they prevent moisture corrosion and thereby extend the longevity of the product. Since the cap/closure mechanism and the container can mechanically secure medications, the nature, purity, and quantity of desiccant used will have a significant impact on the formulation's end-user efficiency.You won't get the same results if you use a standard desiccant.
In reality, using the wrong kind and quantity of desiccant can result in the formulation being over-desiccated, which may be dangerous to patients. As you can see, selecting the right desiccant is crucial. The shortest or most convenient solution isn't necessarily the best option. Use the appropriate desiccant for the work. BhavNil Chemicals Private Limited recognises the importance of selecting the best desiccant. As a result, we deliver a range of sorbents tailored to specific applications. Silica gel and molecular sieve are the two most widely used methods.
When it comes to how they work, the moisture absorption properties of molecular sieve and silica gel vary significantly. Though molecular sieve has a high adsorptive potential at low humidity, silica gel performs poorly in this setting. At room temperature (25°C) and relative humidity of 40%, each has equal moisture preservation capacities.
Silica gel is the safest desiccant to use in products with consistent storage temperatures and high relative humidity. Because of its inert, non-toxic, and highly stable properties, silica gel is a popular desiccant option for many pharmaceutical products.
The molecular sieve, on the other hand, is more active and quick when it comes to moisture absorption, so it's better for materials that require moisture protection right away. The molecular sieve's superior moisture-preservation properties are often maintained over a large temperature range. However, caution should be exercised when selecting the right dosage for use in products with complex RH requirements. Packaging experts must note the following considerations in order to get the best results from the desiccants they use. While choosing the right adsorbent is important, choosing the right desiccant product is also vital, since each performs a different function.
The 3A, 4A, and 13X molecular sieve forms are among the most commonly used. Type 4A is a common choice for pharmaceutical packaging. For more details on the right desiccants for your product, contact our technical sales manager. To get the best performance from the desiccant they use, users can examine a range of testing parameters such as LOD (loss on drying), MAC (moisture adsorption capacity) at low RH and high temperatures, as well as other parameters such as packaging headspace and the regional climate at the product's destination.
Silica gel would undoubtedly improve the compliance of inactive materials such as surgical devices, research kits, and APIs, whereas molecular sieve desiccants would support thermally sensitive medications. Companies involved in the manufacture and processing of these products must use the best adsorbent technologies available, since both over- and under-desiccation can reduce the life cycle and efficacy of formulations.
