Ingredient review
Dimethylcyclohexenyl Methyl Ketone
INCI: DIMETHYLCYCLOHEXYL METHYL KETONE
A synthetic fragrance compound that adds scent but offers no skincare benefit and may irritate sensitive skin.
In plain English
This is a man-made chemical used to give products a pleasant smell—often described as floral, woody, or slightly spicy. It doesn't moisturize, treat, or improve your skin in any way. Its only job is to make the product smell nice. For people with sensitive or reactive skin, it can sometimes cause irritation or allergic reactions, especially in high concentrations or when left on the skin for a long time.

What it is
A synthetic organic compound belonging to the ketone family, used exclusively as a fragrance ingredient in cosmetics and personal care products. It is not derived from natural sources but is manufactured in a lab to produce a consistent scent profile.
How it works
It evaporates from the skin or hair after application, releasing scent molecules that are detected by the nose. It does not interact with the skin's barrier or provide any functional benefit beyond fragrance.
Pros
Consistent scent
Provides a reliable, pleasant fragrance that doesn't vary batch to batch, unlike natural extracts.
Low cost
Synthetic fragrance ingredients are generally inexpensive to produce, keeping product costs down for consumers.
Cons and cautions
Potential irritant
Can cause redness, itching, or stinging in people with sensitive skin, especially in leave-on products like lotions or serums.
No skin benefit
Adds only scent—no moisturizing, anti-aging, or protective properties for the skin.
Best for
- People who enjoy scented products and have no history of fragrance allergies
- Those using rinse-off products like body wash or shampoo where contact time is short
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known fragrance allergy or contact dermatitis
Usage tips
Safety summary
Generally recognized as safe for most people at low concentrations, but can cause skin irritation or allergic reactions in sensitive individuals. Regulatory bodies set usage limits to minimize risk.
Research notes
Limited peer-reviewed studies specifically on this compound, but it is part of a well-studied class of fragrance ketones. IFRA and RIFM (Research Institute for Fragrance Materials) provide safety assessments that support its use within set limits.
Common label clues
- Typical concentration
- Typically less than 1% in leave-on products, often much lower in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, with concentration limits recommended by IFRA to reduce skin sensitization risk.
- Common uses
- Perfumes, Body lotions, Cleansers, Hair products
- Environmental note
- As a synthetic compound, it is not biodegradable and may accumulate in waterways, though typical usage levels are very low.
Good to know
- This ingredient is often listed simply as 'fragrance' or 'parfum' on labels, so it may not appear by name.
- Regulatory bodies like the International Fragrance Association (IFRA) set usage limits to minimize irritation risk.
