Ingredient review
Cyclohexylcyclohexanone
INCI: CYCLOHEXYLCYCLOHEXANONE
A synthetic fragrance ingredient that adds a floral, woody scent; generally considered safe at low concentrations but may cause sensitivity in some individuals.
In plain English
Cyclohexylcyclohexanone is a man-made chemical that smells floral and woody. It's added to products like perfumes and lotions to give them a pleasant scent. Because it's a fragrance ingredient, it doesn't do anything for your skin's health—it's purely for smell. Most people can use it without issues, but if you have very sensitive skin or a fragrance allergy, you might want to avoid it.

What it is
A synthetic organic compound from the ketone family, used as a fragrance ingredient to impart a sweet, floral, and slightly woody aroma.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. It does not actively interact with skin cells or provide any skincare benefit beyond fragrance.
Pros
Pleasant scent
Adds a floral, woody aroma that many people find appealing in perfumes and body products.
Low irritation risk for most
At typical low concentrations, it rarely causes irritation in the general population.
Cons and cautions
No skincare benefit
This ingredient only provides fragrance; it does not moisturize, protect, or improve skin health.
Potential allergen
Like many synthetic fragrances, it can trigger allergic reactions or contact dermatitis in sensitive individuals.
Best for
- People who enjoy scented products and have no known fragrance allergies
- Those using products where fragrance is desired for sensory experience
Use caution if
- Individuals with known fragrance allergies or contact dermatitis
- Those with very sensitive or reactive skin who prefer fragrance-free products
Usage tips
Safety summary
Generally recognized as safe for use in cosmetics at low concentrations. However, it can be a contact allergen for some individuals, so those with fragrance sensitivities should exercise caution.
