Ingredient review
Peracid-Aluminum Complex
INCI: ETHANEPEROXOIC ACID/ALUMINUM ISOPROXIDE/TRIMETHYL-CYCLODODECATRIENE
This is a synthetic processing aid with limited direct skin benefit; it's rarely used in leave-on skincare and may pose irritation risks at higher concentrations.
In plain English
This ingredient is a man-made chemical blend that helps other ingredients stay stable or react properly during manufacturing. It's not something that directly improves your skin, and it's usually present in tiny amounts. Because it's not a common skincare active, there's little research on how it affects skin over time.

Quick decision guide
Read the cautions before using
Peracid-Aluminum Complex 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 Peracid-Aluminum Complex.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A synthetic complex combining a peracid (a strong oxidizing agent), an aluminum compound, and a cyclic hydrocarbon. It's primarily used as a catalyst or stabilizer in industrial or specialty cosmetic processes.
How it works
In a cosmetic product, it may help control the rate of chemical reactions or stabilize other ingredients that would otherwise break down. It does not provide moisturizing, exfoliating, or antioxidant benefits to the skin.
Pros
Enables complex formulations
This ingredient allows chemists to create products with unique fragrance or stability profiles that simpler ingredients cannot achieve.
Used at very low levels
In most cosmetic products, it's present in trace amounts (under 0.1%), reducing the chance of significant exposure.
Cons and cautions
Limited skin benefit
This ingredient does not moisturize, exfoliate, protect, or improve skin appearance. It's purely a processing aid.
Potential irritation risk
Peracids and aluminum compounds can be irritating or sensitizing, especially for those with compromised skin barriers.
Poorly studied in cosmetics
There is very little published research on the long-term safety of this specific complex when applied to skin.
Best for
- Formulators working on complex fragrance or specialty products
- Consumers using rinse-off products where this ingredient is present at very low levels
Use caution if
- Anyone with sensitive or reactive skin
- Those seeking direct skin benefits from their products
Usage tips
Safety summary
Safety data for this specific complex is sparse. The individual components (peracid, aluminum salt, hydrocarbon) have known irritation and toxicity profiles at high doses, but cosmetic exposure is typically minimal. Use with caution, especially on sensitive skin.
Research notes
No peer-reviewed studies on this exact complex in cosmetic applications were found. Research on peracetic acid focuses on disinfection and irritation, while aluminum compounds are studied for antiperspirant use and potential neurotoxicity. More research is needed.
Common label clues
- Typical concentration
- Very low (typically under 0.1%)
- Regulatory status
- Not specifically restricted by the FDA or EU CosIng for cosmetic use, but peracetic acid is regulated as a disinfectant in other contexts. Always follow local regulations.
- Common uses
- Fragrance formulations, Specialty cosmetics
- Environmental note
- Aluminum compounds can accumulate in aquatic environments; however, the very low concentrations in cosmetics are unlikely to cause significant harm.
Good to know
- This ingredient is rarely found in mainstream skincare; it's more common in industrial or fragrance applications.
- The name 'ethaneproxoic acid' is a variant of peracetic acid, a strong disinfectant used in cleaning products.
