Is Silica Gel safe?
Silica Gel is non-toxic and recognized as a “GRAS” (Generally Recognized As Safe) product by the FDA. The industry standard for Dry Food packaging is Silica Gel packaged in Tyvek, Tyvek is a more sturdy and tear resistant material then Cotton. Some types of Silica Gel, which they consider Indicating Silica Gel, have been impregnated with cobalt chloride, which is blue when it is dry and turns to pink when it is saturated. There have been some significant health and environmental risks attributed to the use of cobalt chloride within the Silica Gel including possibly causing cancer, along with skin and respiratory irritation. We, along with several other retailers, offer a safer alternative which is Indicating Silica Gel that goes from orange to green and does not contain cobalt chloride.
