Mentha Viridis Extract

Mentha viridis (spearmint) extract is a botanically derived fragrance/flavoring ingredient that commonly contains sensitizing/irritating terpenes (e.g., carvone, limonene) and can behave similarly to essential-oil components even when used at low concentrations. In clinical practice and patch-test data, mint-derived materials are recurrent triggers for irritant and allergic contact dermatitis, especially in eczema-prone or barrier-impaired skin, and cumulative exposure in a routine (alongside other fragranced products) increases risk. Given the high likelihood of stinging and dermatitis in sensitive populations, it warrants a significant irritancy score. Safety Notes: In commercial skincare, Mentha Viridis (spearmint) extract is most often used as a minor botanical/label claim component in leave-on creams, toners, and serums at very low levels (~0.001–0.1%), reflecting typical supplier recommended use rates and sensitization/odor constraints. Higher levels are seen in consumer-available “cooling/clarifying” masks, aftershaves, and some rinse-off cleansers where botanical extracts are used more assertively for sensory and astringent positioning (commonly ~0.5–2%). The top end (~3%) is observed in high-botanical-load rinse-off or alcohol/water-based splash products; leave-on products rarely approach this level due to irritation potential and fragrance/allergen considerations.
