Salts based on Calcium Chloride are the most powerful and effective dehydrating product of chemical origin. Calcium chloride is over ten times more powerful and hygroscopic than silica gel, however - unlike silica gel - it is not an inert product and is classified as dangerous and irritating.

By absorbing moisture it creates a leachate which is in effect a highly irritating and corrosive special chemical waste. For this reason, bulk calcium chloride salts are totally contraindicated for domestic use and are exclusively intended for industrial uses. Calcium chloride is not allowed in the pharmaceutical field and is not allowed in the food production chain.
