Vermiculite is an inorganic chemical compound, phyllosilicate mineral composed mainly of oxides of silicon, aluminium, magnesium, calcium and iron. It is similar to mica and belongs to the phyllosilicate group, a layered structural type 2: 1. The layers of clay material that make it up are about 1 mm thick and are composed of octahedral alumina or magnesia. It forms when volcanic rock reaches high temperatures.

Safety
Aluminium can interfere with different biological processes (cellular oxidative stress, calcium metabolism, etc.), so it can induce toxic effects in different organs and systems, and the nervous system is the main target of its toxicity.

What it is used for and where
Cosmetics
Skin conditioning agent. It is the mainstay of topical skin treatment by restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants.
