Biodegradable cosmetics packaging

05-Jun-06

PHA is an innovative polymer produced from organic sugars and oils that decomposes and the only products generated during decomposition are carbon dioxide and water. PHA behaves essentially like fossil fuel based polymers when moulded, but has a smaller manufacturing 'window.' Also, the resulting mouldings have proved to be far more heat stable than those from the more popular biodegradable PLA polymer. This property makes PHAs more suitable for the cosmetic packaging market. RPC Cresstale has successfully completed the first trial production of a 100% biodegradable lipstick. This development follows the moulding of a compact using PHA and represents a significant breakthrough in cosmetics packaging. The lipstick uses the RPC patented 'Revolve' mechanism, which boasts a unique collapsible tower. This allows the lipstick, including the decorative cover and base, to be made in only four moulded parts and from one single material, instead of the conventional five components requiring a number of different materials.
