Ingredient review
Hexahydro-Methanoinden-6-yl Isobutyrate
INCI: HEXAHYDRO-METHANOINDEN-6-YL ISOBUTYRATE
A synthetic fragrance ingredient that adds a pleasant woody scent, but has limited safety data and may cause irritation in sensitive individuals.
In plain English
This is a man-made chemical added to skincare and beauty products to give them a warm, woody, or amber-like smell. It's part of a fragrance blend, so you won't see it listed on its own on the label—it's simply part of 'fragrance' or 'parfum.' While generally considered safe at low levels, some people with sensitive skin may find it irritating.
