Material
Talc powder, starch, aluminum compounds
Brand disclosure

Lab data
No public lab test
What’s concerning
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cosmetics is a category where PFAS exposure is more common.
Aluminum compound skin sensitization
Aluminum zirconium and aluminum chlorohydrate are recognized contact allergens in a small percentage of users. This is category-wide, not unique to Arm & Hammer, but susceptible individuals should patch-test.
Inhalation hazard from powder form
Talc powder can be inhaled if applied roughly or in poorly ventilated spaces. Chronic inhalation is not expected from normal deodorant use, but users with asthma or chronic lung conditions should apply with care.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Talc contamination (asbestos residue)
US cosmetic-grade talc has been required to be asbestos-free since the 1970s. No recalls or adverse reports specific to this Arm & Hammer product exist on public record.
Fragrance allergens or undisclosed additives
Arm & Hammer U Max does not list synthetic fragrance in its standard formulation (powder scent is mild), reducing common fragrance allergen risk. Full ingredient transparency is limited; no major allergen incidents are recorded.
Heavy metals
Talc deposits can naturally contain trace metals (iron, magnesium); regulatory limits in cosmetics apply. No independent testing or reports of excess heavy metals in this specific product are available.

What it's made of and why it matters
Arm & Hammer U Max is a solid stick antiperspirant built on talc powder as the primary base, combined with aluminum compounds (likely aluminum zirconium or aluminum chlorohydrate) for sweat-blocking action and starch for texture and absorption. Talc itself is a naturally occurring mineral; the safety concern historically centered on asbestos contamination in talc mining and processing, though cosmetic-grade talc sold in the US has been subject to asbestos-free claims since the 1970s. This product does not list fragrance allergens or known endocrine disruptors in its typical formulation.
The brand's record and disclosure
Arm & Hammer has not published a specific PFAS disclosure or commitment for this product line, and the brand maintains a largely silent stance on PFAS in personal care products. The company has faced no major recalls or lawsuits tied to this specific deodorant or its talc content. Arm & Hammer is owned by Church & Dwight, a large CPG manufacturer, but independent third-party certifications (e.g., Cradle to Cradle, EWG Verified) are not listed for this product.
How it compares in its category
Talc-based powder sticks sit mid-range for safety transparency in the deodorant market. They avoid the PFAS and propellant concerns of aerosols and avoid the occlusive polymer coatings of some gel or cream antiperspirants. However, talc powders offer less precision ingredient disclosure than brands carrying third-party cosmetic certifications or "clean" marketing credentials. Compared to aluminum-free or mineral-only alternatives, this product prioritizes sweat control over ingredient minimalism.
If you buy it
Apply sparingly to clean, dry skin; avoid broken or irritated skin, as aluminum compounds can cause localized irritation in sensitive individuals. Do not inhale the powder directly; apply gently to avoid aerosolization if you have respiratory concerns. Replace the stick every 3 to 6 months or when noticeably reduced to prevent microbial growth in the container. If you experience persistent rash, swelling, or allergic reaction, discontinue and patch-test with a fragrance-free alternative.
