Our Lasting Environmental Commitment: Our commitment to the environment started over 120 years ago, in 1888, when we first introduced bird cards in our Arm & Hammer Baking Soda to encourage the protection of wildlife. Over the past 100 years, we have developed a number of innovative consumer products and industrial applications for purifying drinking water, reducing smokestack emissions, as well as safely and effectively cleaning a wide variety of surfaces. We introduced the first phosphate-free laundry detergent in 1970, and we have continued to provide our consumers with household and personal care products for healthier and more sustainable living.
