Eleven Uses for Silica Gel Packets
While the silica gel by itself isn’t toxic, some of the other compounds that are added to enhance its effects may be harmful.
Even if you don’t recognize it by its name, silica gel is one of those products that’s practically everywhere. You can often find it in small paper shopping bags or in shoe boxes, for example. There are many other uses for silica gel, though, and in this article we’ll explain them to you.
You’ve probably seen the little packets before, but didn’t know what they’re there for, and you’ve just thrown them away. Silica gel is the granular and porous form of silicon dioxide, manufactured from sodium silicate, a water and glass compound.The purpose of these little packets is to help eliminate excess moisture from forming when you store something for a long time. Because of these packets’ porous nature, they help ensure that your products arrive in perfect condition when they otherwise may have been damaged.
However, manufacturers recommend that you take them out of the product once it arrives, because the packets are very fragile and can break open easily.
Silica gel has been around since 1640, and is well known in the scientific community. People used it in a variety of ways in the past, it was a chemistry professor, Walter A. Patrick, who patented it in 1919.
This product was used in the cruel gas chambers of World War II, absorbing the escaped gases and vapors. Interestingly, also in World War II silica gel people used it to keep penicillin stores dry and in good condition. For that reason, it has helped to save many lives.
Silica gel is a drying agent that is useful in many other ways around the house. The gel by itself isn’t toxic, but there are sometimes certain other compounds in it to enhance its effects, such as cobalt chloride, which can be harmful to your health.
