Arm & Hammer is a brand of baking soda-based consumer products marketed by Church & Dwight, a major American manufacturer of household products. The logo of the brand depicts the ancient symbol of a muscular arm holding a hammer inside a red circle with the brand name and slogan. Originally associated solely with baking soda and washing soda, the company began to expand the brand to other products in the 1970s by using baking soda as a deodorizing ingredient.
