Mentha Piperita (Peppermint) Leaf Extract
Peppermint extract

Also written as: Peppermint Leaf Extract · Mentha Piperita Extract
What it is
This is an extract of peppermint leaf, usually made with water, glycerin or glycol rather than by distillation. Because it is not a distilled oil, it contains far less menthol and menthone than peppermint essential oil and is used mainly for a light refreshing character and marketing appeal. The distinction matters: Regulation (EU) 2023/1545 added Mentha Piperita Oil to the allergen labelling list, but not the leaf extract.
What it does well
Gives a mild refreshing character without the sting of the oil
Extracts carry a fraction of the menthol found in the essential oil, so the cooling effect is subtle. There is little clinical evidence for any specific skin benefit.
Limited evidence
Worth knowing
Can still contain enough menthol to matter for sensitive skin
Extract strength varies widely between suppliers. A concentrated extract in a high-percentage formula can still tingle or sting on a compromised barrier.
Matters most toPeople with eczema, rosacea or freshly exfoliated skin.
Where the EU stands
No specific restriction
Peppermint leaf extract is not listed in Annex II and is not on the Annex III fragrance-allergen labelling list. Note that the distilled essential oil, Mentha Piperita Oil, was added as Annex III entry 361 by Regulation (EU) 2023/1545, and menthol itself as entry 338.
