Sustainability Score

While Mucinex's parent company Reckitt has made some commitments to sustainability, their practices lack full transparency and concrete action. Their packaging remains heavily dependent on virgin plastics, and their manufacturing processes have significant environmental impacts. While they have made steps toward ethical sourcing, their supply chain transparency and labor practices documentation need improvement. Their animal testing policies, while compliant with regulations, could be more progressive.
