Paris-based Cosmogen turned heads at Luxe Pack with its patented Self-Heating Tube, designed for products like facial masks, anti-wrinkle formulations, hair products and body oil. The Cosmogen package incorporates two tubes, one inside the other. The outer tube is filled with the product formulation, and the hermetically sealed inner tube contains a sodium acetate solution. When the consumer breaks the peelable security strip on the package’s closure, the sodium acetate solution starts to crystallize. This generates heat, warming up the product.
