Founded in 2010 by Sacha Dunn in her Brooklyn home, Common Good makes refillable household cleaning and personal-care products designed to cut single-use plastic without relying on harsh chemicals. The women-led company uses plant- and mineral-based formulations, including enzyme-powered laundry detergent, and has built its identity around refill packaging and a closed-loop program that sanitizes and reuses liners. Its products are made in the USA and have helped keep more than one million 16-ounce bottles out of landfills.
