Silica Gel for Pharmaceuticals
[Learn more about Medical Type Silica Gel Desiccant]


Pharma Silica Gel



Desiccants are one of the most crucial parts of the pharmaceutical process chain. The accurate selection and use of a desiccant such as silica gel can avert and prevent many problems that frequently occur in pharmaceutical processing and packaging. Most importantly, the right selection of desiccants ensures the purity and performance of the finished products. 

Desiccants are substances or materials that retain and absorb water vapor. Most of the desiccants are usually solids that hold a network of interconnected pores that support water molecules to become adhesive to the large internal surface. The concentration of water vapor in the air is called relative humidity (RH) which indicates the ratio of the amount of water vapor existing in the air to the maximum amount of water vapor that can be contained in the air at a given temperature.

RH (expressed as a percentage) and temperature are the two most important factors during the production and packaging process of the intermediate drugs and the finished drugs. Besides air, packaging materials can be another source of moisture. A desiccant such as silica gel reduces the amount of water vapor in the air and prevents unwanted damage

Moisture and Pharmaceuticals

The quality and appearance of most of the pharmaceutical intermediates and finished medicines along with their preparation process depend mostly on the protection afforded by desiccants. Moisture damages drug production and preservation like no other forces. So, using a good form of protection against moisture; i.e., water vapor is significant for good product presentation, purity, and performance. The value and convenience of the plastic canister or little sachet inside the bottle or foil pouch of the medicine should not be ignored, neglected, or underestimated.

Moisture Damage Effect

Moisture damage in pharmaceuticals may occur in many forms. If no desiccant is used in the bottle or foil pouch, moisture present in the containers and other packaging systems may cause many problems. Typical examples of these problems include:

Reduction in drug potency

Decrease in tablet hardness

Degradation of active intermediates


Development of unpleasant odors

Smeared tablet print

Development of unpleasant odors

Growth of mold and mildew.

Pharmaceutical Grade Silica Gel

Silica Gel got its patent in 1919, but its applications became more distinguished as a desiccant during World War II for protecting the Pharmaceutical Supplies from moisture damage. Pharmaceutical grade silica gel is usually used not only for pharmaceuticals but also in various industries including oil & gas, electronics, paints & coatings, and agrochemicals. However, in the pharmaceutical industries, silica gel is generally used as a solvent in the delivery systems of drugs because it works as a powerful solubilizing agent and also as a penetration enhancer. 

The comprisal of Hygroscopic salts such as calcium chloride and perchlorates in Silica gel demonstrated specific acceptable performance in Pharmaceutical applications. The standards of Silica Gel for Pharmaceutical applications are increasing day by day because of variant needs for absorption capacity at varying RH around the world. Best Silica Gel Packaging (BSP) maintains the global standard and excellent absorption capacity of its products. As the relative humidity RH increases, the adsorption capacity of our desiccant also increases. Therefore, our silica gel is always preferred for Pharmaceutical preparations and purifications around the world. 

So, you have already got the answer to the question where you can buy the Silica gel for pharmaceuticals in terms of specifications and cost; it’s BSP (Best Silica Gel Packaging). No wonder, the best pharmaceutical industries use quality silica gel to ensure that their products and medicines do not fall victim of any form of moisture damage.  

BSP (Best Silica Gel Packaging) is one of the most prominent Silica Gel manufacturers in Bangladesh, which supplies Silica Gel to the biggest pharmaceuticals companies that export tons of medicine every day around the world. BSP (Best Silica Gel Packaging) manufactures all types and grade of silica gel based on performance criteria and quality assurance. Small-scale requirements of Silica Gel are generally attained through Sachets which are of many different sizes ranging from 0.25 grams to 250 Kilograms. These Silica gel sachets in ball form are also available in three colored forms such as blue, orange, and the natural transparent watercolor. The change in color of the balls in the sachet or canister indicates the levels of saturation of the Silica gel. Once it attains its maximum saturation level, it can be rejuvenated at a lower heat of 120 degrees Centigrade.  

So, whenever you are concerned about buying top-grade silica gel, you should leave this matter to us. BSP (Best Silica Gel Packaging) produces and supplies a wide range of varieties of silica gel including ball forms and crystal forms in transparent (colorless) as well as in colored forms along with their specifications such as the range of size for both ball and crystal forms. BSP also provides silica gel according to the specifications of absorption capacities of each of the variations concerning RH (relative humidity), bulk density, composition, and many more.
