A synthetic scent ingredient that adds a pleasant floral note but may cause irritation in sensitive individuals.
In plain English

What it is
A synthetic organic compound belonging to the oxepanone family, used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
It evaporates from the skin or product surface, releasing scent molecules that are detected by the nose. It has no known functional benefit for skin texture, hydration, or appearance.
Pros
Pleasant scent
Adds a light floral-fruity aroma that many people find appealing in lotions, creams, and perfumes.
Low concentration needed
Only a tiny amount is required to achieve the desired fragrance, so it's cost-effective for formulators.
Cons and cautions
Potential irritant
As a synthetic fragrance, it can cause redness, itching, or contact dermatitis in sensitive individuals, especially with repeated use.
No skin benefit
It serves no purpose other than scent—it doesn't moisturize, protect, or improve skin health in any way.
Best for
- People who enjoy scented cosmetics and have no history of fragrance allergies
- Those looking for a specific floral note in their products
Use caution if
- Individuals with sensitive skin, eczema, or known fragrance allergies
