- Is it biodegradable? Whenever possible, biodegradable products are preferred for their minimal environmental impact.
- Is it nontoxic? Choose products that can’t harm workers, guests, or food products.
- Does it contain phosphates? These encourage the growth of algae, which depletes oxygen and kills aquatic life in waterways.
- Does it contain chlorine-based bleach? In wastewater, chlorine may combine with other chemicals to form toxic compounds.
- Is it concentrated? Products that can be diluted in cold water will save money and energy.
- Does it contain a high concentration of volatile organic compounds (VOCs)? In sunlight, VOCs react with nitrous oxides to produce ozone and photoelectric smog.
- Is it made from a petroleum derivative? Look instead for a purely oil-based product, with a pH level as close to 7 as possible to avoid irritation if the product comes into skin contact. (A pH level of 1 is the most acidic; 14 is the most alkaline; 7 is neutral.)
