The Greenlist™ process provides ratings for more than 95 percent of the raw materials we use, including solvents, propellants, insecticides, packaging and more. Through the Greenlist™ process, each raw material receives a rating from 3 to 0, which helps us go beyond regulatory requirements to continually make our products better. An ingredient with a 3 rating is considered “Best,” 2 is “Better,” 1 is “Acceptable” and 0-rated materials are used only on a limited, approved basis when there is not a viable alternative.
