Moisture can cause mold and spoilage in many items. [10] [11] It can also damage electronics by causing condensation and shorten the lifespan of chemicals, like those in vitamins. [citation needed] Silica gel packets help by absorbing moisture and extending the life of these items. [12] [13] [14]
Silica gel in a sachet or porous packet. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant. Commonly encountered pre-packaged desiccants are solids that absorb water. Desiccants for specialized purposes may be in forms other than solid ...
The components of an oxygen absorber vary according to intended use, the water activity of the product being preserved, and other factors. Often the oxygen absorber or scavenger is enclosed in a porous sachet or packet but it can also be part of packaging films and structures. [4] Others are part of a polymer structure. [5]
Use airtight bins and add moisture absorbers or silica gel packets to prevent humidity damage. Plan to protect your decorations from environmental hazards. Failing to detangle string lights.
Colour changing silica may be used to indicate when it should be refreshed. Indication gels typically change from blue to pink (if the indicator is cobalt(II) chloride) as they absorb moisture but other colours may be used. A stopcock may be included to permit the desiccator to be evacuated. Such models are usually known as vacuum desiccators.
List of desiccants: [1]. Activated alumina; Aerogel; Benzophenone (as anion); Bentonite clay; Calcium chloride; Calcium hydride; Calcium oxide; Calcium sulfate ...
