Ingredient review
Butyloxepanone
INCI: Butyloxepanone
Butyloxepanone is a synthetic fragrance ingredient that adds scent but offers no skincare benefits; it's generally safe at low levels but may cause irritation in sensitive individuals.
In plain English
Butyloxepanone is a man-made chemical that gives products a pleasant smell, often described as warm, sweet, or fruity. It doesn't moisturize, treat, or improve your skin—it's purely there for the scent. Because it's a fragrance ingredient, it can sometimes cause irritation or allergic reactions, especially if you have sensitive skin or a history of fragrance allergies.

What it is
Butyloxepanone is a synthetic organic compound belonging to the oxepanone family. It is used exclusively as a fragrance ingredient in cosmetics and personal care products to impart a specific scent profile.
How it works
Butyloxepanone works by evaporating from the skin or hair after application, releasing its aromatic molecules into the air. It does not interact with the skin's biology or provide any functional benefit beyond scent.
Pros
Pleasant scent
Adds a warm, sweet, or fruity aroma that can make the product more enjoyable to use.
Low irritation risk for most
At typical low concentrations, butyloxepanone is generally well-tolerated by people without fragrance sensitivities.
Cons and cautions
No skincare benefit
Butyloxepanone is purely a fragrance ingredient—it does not moisturize, soothe, or improve skin health in any way.
Potential allergen
Like many synthetic fragrances, it can cause contact dermatitis or allergic reactions in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented products and have no history of fragrance allergies
- Those looking for a specific warm or sweet scent profile in their cosmetics
Use caution if
- Individuals with sensitive skin, eczema, or known fragrance allergies
- Anyone preferring fragrance-free or hypoallergenic products
Usage tips
Safety summary
Butyloxepanone is considered safe for use in cosmetics at low concentrations by major regulatory bodies. However, it can be a skin irritant or allergen for some individuals, particularly those with fragrance sensitivities.
Research notes
Research on butyloxepanone is limited to its use as a fragrance ingredient. Safety assessments by the International Fragrance Association (IFRA) and the Research Institute for Fragrance Materials (RIFM) support its safe use at low levels, but no studies show skincare benefits.
Common label clues
- Typical concentration
- Typically used at very low levels, often less than 1%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) as a fragrance ingredient, subject to concentration limits and safety assessments.
- Common uses
- Fragranced lotions, Perfumes, Body washes, Hair products
- Environmental note
- As a synthetic compound, butyloxepanone may persist in the environment after washing off; its ecological impact is not fully studied.
Good to know
- Butyloxepanone is often listed simply as 'fragrance' or 'parfum' on ingredient labels, so you may not see it by name.
- It is not a preservative, humectant, or active ingredient—its only role is scent.
