Rose Ketone-3
INCI: Damascenone
Rose Ketone-3 is a synthetic fragrance ingredient that gives a pleasant rose scent, but may cause irritation in sensitive individuals.
In plain English
Rose Ketone-3 is a man-made chemical used to add a rose-like smell to skincare and perfumes. It is not a natural rose extract but a lab-created compound. Because it is a fragrance ingredient, it can sometimes cause skin reactions, especially for people with sensitive skin or allergies. It is used in very tiny amounts because a little goes a long way for scent.

What it is
Rose Ketone-3, also known as Damascenone, is a synthetic aroma compound that mimics the scent of rose petals. It is part of the ketone family and is widely used in the fragrance industry for its strong, pleasant floral note.
How it works
In a cosmetic product, Rose Ketone-3 acts solely as a fragrance ingredient. It does not provide any skincare benefits like moisturizing or anti-aging. Its purpose is to make the product smell like roses, which can enhance the user experience.
Pros
Pleasant rose scent
Provides a consistent, strong rose fragrance that many find appealing and luxurious in skincare and perfumes.
Very low concentration needed
Only a tiny amount is required to achieve a noticeable scent, which helps keep the overall formula light.
Cons and cautions
Potential skin irritation
As a synthetic fragrance, it can cause redness, itching, or stinging, especially for those with sensitive or reactive skin.
No skincare benefit
It adds only scent and does not moisturize, protect, or improve the skin in any way.
Best for
- People who enjoy rose-scented products and do not have fragrance sensitivities
- Those looking for a consistent, stable rose scent without natural variations
Use caution if
- Individuals with sensitive skin or known fragrance allergies
- Anyone following a fragrance-free skincare routine
Usage tips
Safety summary
Rose Ketone-3 is generally considered safe for use in cosmetics at low concentrations, but it can be a skin irritant and allergen for some people. Regulatory bodies require labeling when it exceeds certain thresholds in the EU.
Research notes
Research indicates that Damascenone is a common fragrance allergen, with patch test studies showing positive reactions in a small percentage of people with suspected fragrance allergy. It is not associated with long-term health risks at cosmetic use levels.
Common label clues
- Typical concentration
- Very low, typically less than 0.1%
- Regulatory status
- Approved for use in cosmetics in the EU and US, but must be listed as a fragrance allergen if present above certain levels in the EU.
- Common uses
- Perfumes, Fragranced skincare, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, its production does not rely on rose cultivation, which can be resource-intensive. However, its environmental persistence is not well studied.
Good to know
- Rose Ketone-3 is often listed simply as 'fragrance' or 'parfum' on ingredient labels, so it may not appear by name.
- It is not the same as natural rose oil, which contains many different compounds.
