From the manufacturer

BD ECO Liquid Gold gives you the extra grip to stick the last moves on your project. 

Made from pure magnesium carbonate, which is the byproduct of the desalination process, as opposed to being mined from the earth like typical climbing chalk, ECO Liquid Gold is purer and more eco-friendly than other chalk products on the market. In other words, ECO Gold is as easy on the environment as it is on your hands. Plus, it’s non-toxic and dust-free, which keeps mess to a minimum.
