Michael Lefenfeld came up with the idea for SiGNa Chemistry in 2002 after his grandfather asked him to solve a problem: He wanted something that would work like an air freshener, but for the toilet.
After partnering with a chemist, he built SiGNa, which manufactures safe, user-friendly alkali metals — which are typically very combustible — for larger-scale chemical reactions.
SiGNa’s more environmentally friendly products are now being applied far beyond the bathroom, including for oil recovery, petrochemical refining, pharmaceutical manufacturing, alternative energy production, and speciality chemical processing.
