What is the metal in group 15 that is part of compounds often found in cosmetics?

Answer 1

The metal is bismuth.

The most common bismuth compound found in cosmetics is bismuth oxychloride, #"BiOCl"#.

It is also known as "synthetic pearl", because light wave interference from its plate-like structure gives it a pearly appearance.

It is often used in nail polish, bronzers, blush, and eyeshadows because of its shimmery look and the silky feel it has on the skin.
