Trimethyl Cyclohexenylethanone
INCI: 1-Trimethyl-3-Cyclohexenylethanone
A synthetic fragrance ingredient that adds a pleasant floral-woody scent but may cause skin irritation in sensitive individuals.
In plain English
This is a man-made chemical used to give skincare and beauty products a specific scent, often described as floral or woody. It doesn't provide any skincare benefits like moisturizing or anti-aging—it's purely for fragrance. Some people with sensitive skin may find it irritating, so it's worth patch testing if you're prone to reactions.

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.

moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic aromatic compound belonging to the cyclohexenyl ketone family, used primarily as a fragrance ingredient in cosmetics and personal care products.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by olfactory receptors. In a product, it masks any base odors and contributes to the overall fragrance profile.
Pros
Pleasant scent profile
Adds a floral-woody aroma that many find appealing, enhancing the user experience of a product.
Low comedogenic risk
Unlikely to clog pores, making it suitable for non-acne-prone skin types when used in rinse-off products.
Cons and cautions
Potential irritant
Can cause redness, itching, or stinging in sensitive individuals, especially with prolonged leave-on use.
No skincare benefit
Provides only fragrance—no moisturizing, antioxidant, or anti-aging properties, so it adds no functional value to a formula.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those using products where fragrance is desired for sensory experience
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known fragrance allergy or contact dermatitis
