What it is
A synthetic ketone compound used as a fragrance ingredient in cosmetics and personal care products. It is not a natural extract but is created in a lab to mimic or enhance certain scents.
How it works
It evaporates from the skin's surface, releasing scent molecules that your nose detects. It does not penetrate deeply or interact with skin cells in a meaningful way—its only role is to provide fragrance.
Pros
Pleasant scent
Provides a clean, floral, or fruity fragrance that many people enjoy in their daily skincare routine.
Low comedogenic risk
Unlikely to clog pores, so it's generally safe for acne-prone skin in terms of breakouts.
Cons and cautions
Potential irritant
As a synthetic fragrance, it can cause redness, itching, or stinging, especially on sensitive or compromised skin.
No skin benefit
It adds no moisturizing, anti-aging, or protective value—it's purely for sensory appeal.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those using rinse-off products like body wash where exposure is brief
Use caution if
- Anyone with sensitive, reactive, or eczema-prone skin
- Those with known fragrance allergies or contact dermatitis
Usage tips
Safety summary
Generally recognized as safe for most people at low concentrations, but it is a known potential allergen and skin irritant. People with fragrance sensitivities should avoid it.
Research notes
Limited peer-reviewed studies specifically on this compound, but it is part of the broader category of synthetic fragrance ingredients that are monitored by IFRA and the EU CosIng database for allergenicity.
Common label clues

- Typically less than 1% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, subject to concentration limits set by fragrance safety organizations.
- Common uses
- Perfumes, Fragranced skincare, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, it may not biodegrade as readily as natural fragrances, but its environmental impact is not well-studied.
Good to know
- This ingredient is often listed simply as 'fragrance' or 'parfum' on labels, so it can be hard to spot unless the full INCI is disclosed.
- Regulatory bodies like the IFRA (International Fragrance Association) set safety limits for its use in cosmetics.
