What's silica gel and so why do I've found little packets of it in everything I purchase,[link widoczny dla zalogowanych]
Little packets of silica gel are located in most types of products because silica gel is a desiccant -- it adsorbs and holds water vapor. In leather products and foods like pepperoni,[link widoczny dla zalogowanych], the possible lack of moisture can limit the development of mold and reduce spoilage. In electronics it prevents condensation,[link widoczny dla zalogowanych], which might damage the electronics. If your bottle of vitamins contained any moisture vapor and were cooled rapidly,[link widoczny dla zalogowanych], the condensing moisture would ruin the pills. You will find little silica gel packets in anything that could be impacted by excess moisture or condensation.
Silica gel is nearly harmless,[link widoczny dla zalogowanych], which is why you find it in foods. Silica,[link widoczny dla zalogowanych], or silicon dioxide (SiO2),[link widoczny dla zalogowanych], is the same material found in quartz. The gel form contains an incredible number of tiny pores that may adsorb and hold moisture. Silica gel is essentially porous sand.
Silica gel can adsorb about 40 % of their weight in moisture and may take the relative humidity inside a closed container right down to about 40 percent. Once saturated,[link widoczny dla zalogowanych], you can drive the moisture off and reuse silica gel by heating it above 300 degrees F (150 C).
