How is Bismuth Oxychloride created ?



Bismuth is a brittle metal which was first named in that late 1660's. It is a bright white metal that is very brittle in a raw state. Discoloration can occur when the metal is in the presence of oxygen.

It is a rare substance but not as rare as Gold. In fact it is calculated that it is roughly twice as common as gold. It is found in China, Australia but viens of it can be found in other locations around the world
huge amounts of Bismuth are needed in the cosmetics industry. The manufacturers of  bismuth generally produce it as a by-product from refining lead, copper and tin.

Bismuth then has to go through a long and complicated process to create bismuth oxychloride which is needed for cosmetics.

How is it Processed?

Firstly the metal is separated into a rough mix through smelting but the process leaves many impurities.

Impurities can only be removed through adding other ingredients this mix is then mixed with water and dried. A solution of nitirc acide is then used to wash out the impurities and leave the bismuth oxychloride.

So when someone tells  you that mineral foundations are completely natural, you wil know they could not be further from the truth.
