Dimethylcyclohexenyl Tert-Butyl Ketone
INCI: DIMETHYLCYCLOHEXENYL TERT-BUTYL KETONE
A synthetic fragrance ingredient that adds scent but offers no skin benefit and may cause irritation in sensitive individuals.
In plain English
This is a man-made chemical used to give skincare and beauty products a pleasant scent, often described as warm, woody, or floral. It does not moisturize, treat, or improve your skin in any way — its only job is to make the product smell nice. For people with sensitive skin, it can sometimes cause redness or irritation.

What it is
A synthetic organic compound from the ketone family, specifically designed for use as a fragrance ingredient in cosmetics and personal care products.
