Ethical Sourcing

As a subsidiary of Ecolab, Inc., Nalco has adopted the Ecolab Ethical Sourcing Standards, a global supply chain initiative requiring our direct suppliers to protect the health, safety and human rights of their employees. Suppliers must meet standards regarding forced labor, child labor, health and safety, fair pay, and harassment in the workplace.

In accordance with the California Transparency in Supply Chains Act of 2010, information about supplier standards for Nalco is available here.
