About

Lemon myrtle leaf water with very high citral content, making it both potent and regulated as a fragrance allergen in the EU.

Backhousia citriodora (lemon myrtle) is one of the highest natural sources of citral (up to 90%). Citral is a registered fragrance allergen under EU Annex III. The leaf water form is a diluted steam distillate, but still requires allergen labelling considerations. The high citral content means careful concentration control is essential for safe cosmetic formulation.

Skin benefits

Known concerns

  • Citral is a regulated EU fragrance allergen (Annex III)
