Description

Plastics have been applied as ingredients in PCCPs for several decades with early patents dating from the 1960’s – today they remain a hotbed of innovation in new PCCPs. Plastic is a term for materials made from certain types of synthetic polymers. Besides polymers, plastics also contain other substances (e.g. additives) which help achieve the desired properties of the material.

The plastic materials applied as ingredients in PCCP formulations discussed here include two main categories: thermoplastics e.g. polyethylene, polypropylene, polystyrene, polyamide polytetrafluoroethylene (Teflon), poly (methyl methylacrylate), and thermoset plastics, e.g. polyurethanes and certain polyesters.

While many polymers used in PCCPs are water soluble or waterdispersable, some silicone polymers are amorphous solids (without a clearly defined shape or form) and with virtually no water solubility (Cosmetic Ingredient Review 2011; Perry 2005).
