Owned by Church & Dwight, Arm & Hammer is one of the most enduring American household brands, famously centered around the versatile utility of sodium bicarbonate, or baking soda. Originally established in 1846 by John Dwight and Austin Church, the brand is instantly recognizable by its “Vulcan” logo—a muscular arm wielding a hammer—symbolizing the strength and power of its chemical leavening agent. Over nearly two centuries, Arm & Hammer has successfully expanded far beyond the kitchen pantry, leveraging the deodorizing and abrasive properties of baking soda to dominate diverse categories including laundry detergent, toothpaste, cat litter, and personal care products. By positioning itself as an eco-friendly and multi-purpose solution for cleaning and health, the brand has maintained a reputation for reliability and affordability, cementing its status as a ubiquitous fixture in millions of homes worldwide.
