INCI: TRANS-ROSE KETONE-3
A synthetic rose-scented fragrance ingredient that adds a pleasant floral note but offers no skincare benefits.
In plain English

What it is
A synthetic aromatic ketone that mimics the scent of rose petals, commonly used as a fragrance ingredient in cosmetics.

Usage tips
Safety summary
Trans-Rose Ketone-3 is considered safe for most people at the low concentrations used in cosmetics. However, like all fragrance ingredients, it can cause allergic reactions in sensitive individuals. Regulatory bodies require it to be listed on labels when present above certain thresholds.
Research notes
Research on this specific compound is limited, but fragrance ingredients as a class are well-studied for allergenicity. The EU Scientific Committee on Consumer Safety (SCCS) has reviewed similar rose ketones and found them safe at low levels.
Common label clues
- Typical concentration
- 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 and labeling requirements for allergens.
- Common uses
- Perfumes, Facial creams, Body lotions, Cleansers
- Environmental note
- As a synthetic compound, its environmental impact is generally lower than harvesting natural rose oils, but it is not biodegradable in all conditions.
Good to know
- Trans-Rose Ketone-3 is often listed simply as 'fragrance' or 'parfum' on labels, so it may not appear by name.
- It is not the same as natural rose oil, which contains many additional compounds.
