What it is
A gamma-lactone compound naturally present in Camellia japonica flowers. It is extracted and used in cosmetics primarily for its pleasant floral aroma and mild skin-conditioning properties.

Usage tips
Safety summary
Considered safe for most people when used at low concentrations in rinse-off or leave-on products. However, as a fragrance ingredient, it carries a moderate risk of skin sensitization and should be avoided by those with fragrance allergies.
Research notes
Research on this specific compound is sparse. Most safety data comes from general studies on fragrance ingredients and gamma-lactones, which indicate low acute toxicity but potential for allergic contact dermatitis in susceptible individuals.
Common label clues
- Typical concentration
- Typically used at very low levels (under 1%) due to its potent scent and potential for skin sensitivity.
- Regulatory status
- Approved for use as a fragrance ingredient in cosmetics in the EU, US, and other major markets, subject to general safety requirements for fragrance allergens.
- Common uses
- Facial serums, Moisturizers, Perfumed creams
- Environmental note
- Sourced from Camellia japonica flowers, which are cultivated in East Asia. The extraction process is typically solvent-based, but the ingredient is used in very small amounts, limiting environmental impact.
Good to know
- Gamma-lactones are a class of compounds often responsible for fruity or floral aromas in nature.
- This ingredient is not the same as camellia oil (Camellia oleifera seed oil), which is a different part of the plant used for moisturizing.
