DuPont™ Selar® PA – a high barrier resin for mascara and nail polish packaging

27.10.2010
Luxe Pack 2010 marks the commercial introduction of two new and enhanced grades of DuPont™ Selar® PA amorphous nylon, Selar® PA 3426R and Selar® PA 7003, targeted for use as a high barrier resin for demanding solvent-based applications such as waterproof mascaras and nail polish containers, meeting industry demands for performance, aesthetics and sustainability.

Solvent-based waterproof mascara and nail polish require their containers to provide high barrier performance in terms of water vapor, aroma and solvents in order to minimize weight loss. Beyond this barrier requirement, Selar® PA can provide superior optics, a glossy and scratch resistant surface, excellent solvent and chemical resistance and excellent compatibility with decoration methods such as varnishing, printing and metallization.

New impact-modified DuPont™ Selar® PA 7003, designed for use in waterproof mascara tubes, provides increased drop impact resistance (as illustrated in chart above) and enhanced processability versus incumbent materials.

Selar® PA 3426R, for use in nail polish containers, combines all of the above attributes with superior transparency to rival the clarity and chemical inertness of glass, without its weight and brittleness. Alternatively, new impact-modified Selar® PA 7003, designed for use in waterproof mascara tubes, provides increased drop impact resistance and enhanced processability versus incumbent materials. Its enhanced wall thickness distribution creates the potential for manufacturers to further reduce the wall thickness of their containers, thereby decreasing production costs. Such benefits have recently seen the new material gaining qualification for use in its mascara packaging by L’Oreal’s Expertise Packaging Center in France.

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
