What it is
A synthetic organic compound from the naphthalene family, specifically designed to mimic natural woody or amber scents. It is not derived from plants or animals.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. It has no active effect on skin structure or function.
Pros
Pleasant scent
Adds a warm, woody-amber fragrance that many find appealing and long-lasting.
Low irritation for most
At typical low concentrations, it is generally well-tolerated by people without fragrance sensitivities.
Cons and cautions
No skin benefit
This ingredient is purely for scent and does not hydrate, protect, or improve skin health.
Potential allergen
As a synthetic fragrance, it can trigger contact dermatitis or allergic reactions in sensitive individuals.
Best for
- People who enjoy scented products and have no history of fragrance allergies
- Those looking for a warm, woody scent in their routine
Use caution if
- Individuals with sensitive skin, eczema, or known fragrance allergies
Usage tips
Safety summary
Generally considered safe for most people at the low concentrations used in cosmetics. However, like all fragrance ingredients, it can cause allergic reactions in susceptible individuals. The International Fragrance Association (IFRA) sets usage limits to minimize risk.
Research notes
Research on this specific compound is limited, but it is part of a class of synthetic fragrances that have been evaluated for safety by fragrance industry panels. Studies show low acute toxicity and skin irritation at typical use levels, but allergic contact dermatitis is a known risk for fragrance-sensitive people.
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions, but must be listed on the label if it is a known allergen above a threshold (e.g., 0.01% in leave-on products in the EU).
- Common uses
- Fragranced skincare, Perfumes, Body lotions, Hair products
- Environmental note
- As a synthetic compound, its environmental persistence and bioaccumulation potential are not fully studied, but it is used in very small amounts.
Good to know
- Fragrance ingredients like this one are often listed simply as 'fragrance' or 'parfum' on labels, so you may not see the full chemical name.
- Regulations in many regions require listing specific fragrance allergens if they exceed certain concentrations.
