Does method contain optical brighteners?
Method uses a brightening agent in our laundry detergent to improve performance, particularly for white laundry. Our external materials review partner, EPEA, completed a comprehensive environmental and toxicological assessment of the ingredient (http://www.methodhome.com/behind-the-bottle/green-chemistry.aspx) and deemed it safe: non-toxic to people, not irritating to skin, not carcinogenic, not accumulative in the environment and biodegradable. The ingredient is made from synthetic materials, which is not preferable due to their lack of renewability, but since its safety is well established and use level is minimal (under 0.05%), we are confident using it until a renewable alternative is developed.
