Perfect Preservation of Hera Mascara Thanks to the Barrier Properties of Selar® PA
Hera's mascara tube has a deep black color and is very shiny. This look is achieved thanks to DuPont™ Selar® PA amorphous polyamide resin, which provides durable protection for the cosmetic content.
But the reasons that led Hera to opt for Selar® PA go much further than just aesthetic considerations. Hera wanted to find a material compatible with the waterproof formulation of the mascara as well as with the technical specifications for the tube. Cosmetic companies and molders have turned to chlorine and halogen free solutions, and have found that Selar® PA, DuPont’s amorphous polyamide is the right substitute material.
