Cyclopentasiloxane
Cyclopentasiloxane (also known as Decamethylcyclopentasiloxane) is a 5-unit cyclic silicone with a water-thin consistency. It is classified as a volatile silicone, meaning it evaporates from the skin rather than remaining on it. It is frequently combined with non-volatile dimethicone to form a water-resistant, breathable protective barrier on the skin.
