What it is
A synthetic bicyclic ketone compound used exclusively as a fragrance ingredient in cosmetics and personal care products. It is not derived from plants or natural sources.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. In a product, it simply contributes to the overall fragrance profile and has no active skincare function.
Pros
Pleasant scent
Adds a fresh, woody, or floral note that many people find appealing in lotions, cleansers, and perfumes.
Low irritation for most
At typical low concentrations, it is generally well-tolerated by people without fragrance sensitivities.
Cons and cautions
No skincare benefit
This ingredient only provides scent; it does not hydrate, protect, or improve the skin in any way.
Potential allergen
Like many synthetic fragrances, it can cause allergic reactions or contact dermatitis in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented skincare and have no history of fragrance allergy
- Those looking for a fresh, clean scent in their products
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known fragrance allergy or contact dermatitis
Usage tips
Safety summary
Generally considered safe for most people at low concentrations used in cosmetics. However, like all fragrance ingredients, it carries a risk of skin sensitization and allergic contact dermatitis in susceptible individuals.
Research notes
There is limited peer-reviewed research specifically on this compound. Its safety is evaluated as part of broader fragrance ingredient assessments by bodies like the International Fragrance Association (IFRA) and the Research Institute for Fragrance Materials (RIFM).
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1%
- Regulatory status
- Approved for use in cosmetics in the US and EU. In the EU, it must be listed on the label if it is one of the recognized fragrance allergens, but it is not currently classified as a restricted allergen.
- Common uses
- Perfumes, Fragranced lotions, Cleansers, Body washes
- Environmental note
- As a synthetic compound, it may persist in the environment. Some synthetic fragrance ingredients have been detected in waterways, though specific data on this compound is limited.
Good to know
- Fragrance ingredients are often listed simply as 'fragrance' or 'parfum' on labels, so this specific compound may not always be named individually.
- Regulations in the EU require certain fragrance allergens to be listed separately on the label if present above a threshold.
