Polypropylene, or polypropene, is commonly shortened to PP. It is the second most widely used commodity plastic after polyethylene (PET). The most common type of plastic used in cosmetic packaging is PP. Other plastics include PET and acrylic ingredients. Acrylic plastic has the appearance of glass but doesn't break like glass.
