Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(ethylene)) is the most common plastic. Its primary use is in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.).
Polytheylene is used in a variety of skin care and beauty products, including as eyeliners, mascara, eye shadows, eyebrow pencils, lipstick, blushers, face powders and foundations, as well as in skin cleansers and skin care products, because of its versatile properties as an abrasive ingredient, adhesive, binder, bulking agent, emulsion stabilizer, film former, oral care agent and as a viscosity increasing agent.
Polytheylene is also a main component of Polyethylene Glycols, or PEGs.
