Purity for over 165 years. I's true that all baking sodas meet minimum quality standards before they can reach the consumer, but despite popular belief, all baking sodas are not made with the same level of care. For over 165 years, Arm & Hammer® Baking Soda has exceeded quality standards to deliver a product that maintains a commitment to purity and quality. That places Arm & Hammer® Baking Soda in a category apart from any other baking soda. Our purity meets the most stringent requirements and conforms to pharmaceutical and food code standards around the world. Not every baking soda can make that claim. Because we understand it's important to you, Arm & Hammer® Baking Soda is committed to making sure that what you put into your body and use in your home is pure as it can be. As always, Arm & Hammer® Baking Soda is the natural and affordable solution for cleaning and freshening throughout your home.
