For its new Diorshow Pump'N'Volume Mascara, Christian Dior will utilize a thermoplastic elastomer from Kraiburg TPE.
The mascara container was designed to be squeezed two or three times to load the brush with product. In order to achieve this, Kraiburg TPE's Thermolast K was selected to give the flexibility required. The pack is made with a two-component injection molding process; the internal structure is in copolyester and the skin is made with the Kraiburg TPE compound.
Sylvain Coutan, project manager from Mayet SAS, Texen group, explained, "The decisive factor for us was that the TPE compound could ensure the compromise between copolyester adhesion, softness and low hardness while ensures the elastic recovery after repeated squeezing that the mascara packaging needs to have during the product’s whole life cycle."
Marion Defour-Colas, makeup packaging development group manager at Christian Dior, added, “The new functional principle of the Diorshow Pump’N’Volume Mascara means that the mascara is loaded by gently squeezing the container, making it possible to create an extremely expanded lash volume. To achieve this, we were looking for a material solution that was both flexible and esthetic to be processed by multi-component injection molding. Together with Mayet, our mascara and packaging specialist, and Kraiburg TPE we have chosen a TPE compound that provides the perfect combination of properties for this application specification.”
Michael Pollmann, sales & marketing director at Kraiburg TPE, concluded, "The modern packaging market sets high standards for the function and esthetic quality of materials. This applies particularly to cosmetics packaging that creates a long-lasting consumer experience using a design that appeals to the eyes and to the touch. Whether it’s creams, perfumes or lotions—wherever attractive and functional hard-soft combinations are required, our TPE compounds provide the perfect solution."
