Ingredient review
Methoxyacetophenone
INCI: Methoxyacetophenone
Methoxyacetophenone is a synthetic fragrance ingredient that adds a sweet, floral scent to products; it is generally considered safe at low levels but offers no direct skincare benefit.
In plain English
Methoxyacetophenone is a man-made chemical that smells sweet and floral, like hawthorn or anise. It is added to skincare and beauty products to give them a pleasant scent. It does not moisturize, treat acne, or improve skin health on its own. Because it is used in tiny amounts, it rarely causes problems, but people with very sensitive skin or fragrance allergies may want to avoid it.

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 Methoxyacetophenone.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
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
Methoxyacetophenone is a synthetic aromatic compound belonging to the acetophenone family. It is created in a lab and used in cosmetics primarily for its fragrance properties, often described as sweet, floral, and slightly almond-like.
How it works
In a cosmetic product, methoxyacetophenone acts as a fragrance ingredient by binding to olfactory receptors in the nose, creating a pleasant scent experience. It may also function as a stabilizer, helping to preserve the intended fragrance profile of the product over time.
Pros
Pleasant scent
Adds a sweet, floral note that can make the product more enjoyable to use.
Low irritation potential
At typical low concentrations, it rarely causes irritation for most people.
Cons and cautions
No skin benefit
It does not hydrate, soothe, or treat any skin condition; its only role is scent.
Potential allergen
Like many fragrance ingredients, it can trigger allergic reactions in sensitive individuals.
Best for
- People who enjoy scented skincare products
- Those without known fragrance allergies
Use caution if
- Individuals with diagnosed fragrance allergies or very sensitive skin
Usage tips
Safety summary
Methoxyacetophenone is considered safe for use in cosmetics at typical low concentrations. It is not a known carcinogen or reproductive toxin. The main safety concern is its potential as a skin allergen for fragrance-sensitive individuals.
Research notes
Research on methoxyacetophenone is limited, but it is included in fragrance safety assessments by the Research Institute for Fragrance Materials (RIFM), which has found it to be safe at current usage levels. No peer-reviewed studies indicate significant health risks.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 1%
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database, with no specific concentration restrictions beyond general fragrance safety guidelines.
- Common uses
- Fragranced products, Lotions, Cleansers, Perfumes
- Environmental note
- As a synthetic compound, its environmental persistence is low, but it is not biodegradable in all conditions; however, its low usage volume minimizes impact.
Good to know
- Methoxyacetophenone is often listed simply as 'fragrance' or 'parfum' on labels, so it may not appear by name.
- It is not the same as acetaminophen (a pain reliever) despite the similar name.
