Overview
Arm & Hammer's 2.7 pound resealable bag of baking soda, positioned as a household staple covering baking, laundry, cleaning and craft uses. Made and packaged in Green River, Wyoming.
The listing emphasizes USP grade purity for baking results like fluffier cakes and cookies, alongside a long list of non-baking uses from carpet freshening to science experiments. It also notes production using certified renewable energy, a manufacturing detail rather than a performance claim.

- USP grade 1 crystals
- No additives, cornstarch or fragrance
- Made in Green River, Wyoming with renewable energy
Who it's for
Suits households that go through baking soda across both cooking and cleaning and want a larger resealable bag instead of restocking a small box. Less useful for someone who only bakes occasionally and would rather buy a smaller size.
Pros and cons
- Resealable 2.7 lb bag
- USP grade for baking, kosher and vegan friendly
- No additives, chemicals, cornstarch or fragrance
- Pouring may be less tidy than a shaker
- Large size may sit unused if only baking occasionally
Performance notes
The USP grade crystals are what the brand credits for a more consistent rise in baked goods like cakes and muffins, while the resealable bag format is meant to keep the larger 2.7 lb quantity usable over time rather than exposed after the first opening.
