Ingredient review
Aluminum Bromohydrate
INCI: ALUMINUM BROMOHYDRATE
Aluminum bromohydrate is a common antiperspirant active that effectively reduces sweat but may cause irritation for sensitive skin.
In plain English
Aluminum bromohydrate is a type of aluminum salt used in antiperspirants. When applied to the skin, it dissolves and forms a temporary gel-like plug inside the sweat ducts. This plug physically blocks sweat from reaching the skin's surface, reducing wetness. It's similar to aluminum chlorohydrate but with bromine instead of chlorine. While effective, it can be irritating for some people, especially after shaving or on broken skin.
Quick decision guide
Useful, but context matters
Aluminum Bromohydrate can be useful, but watch for some irritation potential.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Aluminum Bromohydrate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Aluminum bromohydrate is a synthetic aluminum salt compound used as an antiperspirant active ingredient. It belongs to the same family as aluminum chlorohydrate and aluminum zirconium complexes.
How it works
When applied to the skin, the aluminum ions dissolve in sweat and form a temporary gel-like plug within the sweat duct. This plug physically blocks the release of sweat to the skin surface, reducing perspiration. The effect is reversible as the skin naturally sheds over time.
Pros
Effective sweat control
Aluminum bromohydrate significantly reduces underarm wetness by forming temporary plugs in sweat ducts, providing reliable protection for daily use.
Long-lasting protection
A single application can keep you dry for 24 hours or more, making it convenient for busy lifestyles.
Cons and cautions
Potential skin irritation
This ingredient can cause stinging, redness, or itching, especially if applied right after shaving or on sensitive skin. It may not be suitable for everyone.
Residue on clothing
Like many aluminum-based antiperspirants, it can leave white or yellowish marks on dark fabrics, which may require extra care when washing.
Best for
- People looking for effective sweat reduction in antiperspirants
- Those who tolerate aluminum-based antiperspirants well
Use caution if
- Individuals with sensitive or easily irritated underarm skin
- Those who prefer aluminum-free or natural deodorant options
Usage tips
Safety summary
Aluminum bromohydrate is considered safe for topical use in antiperspirants at regulated concentrations. Some people experience skin irritation, and long-term health concerns have been studied but not conclusively proven. If you have sensitive skin or prefer to avoid aluminum, consider alternatives.
Research notes
Research shows aluminum-based antiperspirants effectively reduce sweat. Studies on potential links to breast cancer or Alzheimer's disease have not found consistent evidence of harm from cosmetic use. The FDA and EU CosIng consider it safe within specified limits.
Common label clues
- Typical concentration
- Typically 5–25% in over-the-counter antiperspirants
- Regulatory status
- Approved as an antiperspirant active ingredient in the US (FDA OTC monograph) and EU (CosIng). Concentrations are typically limited to ensure safety.
- Common uses
- Antiperspirant sticks, Roll-ons, Sprays, Creams
- Environmental note
- Aluminum compounds are mined and processed, which has environmental impacts. However, the amounts used in personal care are small relative to industrial uses.
Good to know
- Aluminum bromohydrate is less common than aluminum chlorohydrate but works similarly.
- The FDA regulates aluminum-based antiperspirants as over-the-counter drugs in the US.
- Some studies have linked aluminum to breast cancer or Alzheimer's, but major health organizations (e.g., American Cancer Society, Alzheimer's Association) say there is no strong evidence of harm from cosmetic use.
