Product Review

It is important to handle Silicon dioxide correctly. This will increase the products shelf life and keep people safe. It can irritate eyes and skin if they are exposed to it. Avoid inhalation and wear a mack whilst handling it. If the product is handled properly, it will stay in excellent condition until it’s ready for use.

Silicon dioxide has a high porosity which allows it to absorb up to 300g of fluid per 100g of silica. This means that liquid ingredients can turn into free-flowing powders with ease. It acts as a glidant, a substance used in a formula to improve its flow qualities. It ensures that the product flows through machinery and doesn’t stick to the equipment. Using silica will also increase the stability of moisture sensitive API’s. An API is an “active pharmaceutical ingredient.” This ability will reduce trace quantities of moisture which can cause machinery degradation. It has a unique moisture absorption. This encourages quick tabletting due to it's resistance to capping and sticking.

Silicon dioxide absorbs moisture from its surroundings. Cosmetic and food manufacturers often use it for this reason. These applications are also desired by pharmaceutical companies. The different benefits work together to create an easier and smoother manufacturing process.
