We know that the packaging of effervescent tablets—the effervescent tube has very high requirements for moisture-proof performance, because due to the characteristics of effervescent tablets, it will cause disintegration and deterioration after being exposed to moisture. Today, I would like to share with you the desiccants that play an important role and their characteristics.

The main material of the desiccant used in the effervescent tube is silica gel and molecular sieve. Among them, silica gel is a highly active adsorption material, with a very fine pore network structure inside, which can be used to absorb water and retain water, and it is an extremely suitable desiccant at room temperature, while it can desiccate the environment at high temperature. Humidity is reduced to the point where it does not affect the medicine.
Molecular sieve desiccant is a synthetic product. It has regular and uniform pores in its crystal structure. The pore diameter is on the order of molecular size. To be sieved, it is called molecular sieve. Its material can absorb water vapor and other gases at the same time. And the moisture absorption effect is fast.
The desiccant in the packaging of effervescent tablets is generally a mixture of silica gel and molecular sieve in equal proportions. Silica gel has strong moisture absorption capacity and molecular sieve has a fast moisture absorption speed. After the two are mixed, they can achieve a good moisture absorption effect and ensure the stability of effervescent tablets.
