Silicones are a large group of compounds that include large
polymers containing silicon. Depending on the formula and
the degree of polymerization and cross-linking of the polymers,
they may be slippery liquids, waxes, or rubbers.
Silicones are used as emollients (skin softeners), as lubricants,
as thickeners, and as volatile liquids that make coatings feel smooth,
but evaporate without leaving a greasy residue.
Highly cross-linked silicone films are used in cosmetics to form
films that absorb sebum (skin oils) and prevent shine.
