L-Menthol ●
TL;DR. This ingredient is used as a cooling sensory agent, flavor, and fragrance component in lip care, oral care, shaving products, body care, and scalp formulas. It creates a cold-feeling effect on skin and mucosa without actually lowering temperature.
What does L-Menthol do in a cosmetic formula?
This ingredient is used as a cooling sensory agent, flavor, and fragrance component in lip care, oral care, shaving products, body care, and scalp formulas. It creates a cold-feeling effect on skin and mucosa without actually lowering temperature.
Is L-Menthol clean?
Clean-beauty frameworks generally allow it, but it comes with a sensitivity caveat because the cooling effect can feel sharp on reactive skin, lips, eyes, or freshly shaved areas. It is usually treated as acceptable with careful use levels rather than as an unrestricted comfort ingredient.
Is L-Menthol sustainable?
This material can be sourced from mint crops or made synthetically, so its sustainability profile depends on origin and traceability. It is a small, biodegradable terpene-type molecule, with lower persistence concerns than many silicone or fluorinated sensory materials.
Is L-Menthol COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic standards when derived from approved natural sources and processed with permitted methods, while synthetic versions may not qualify for those categories. From a Green Chemistry view, the best alignment comes from renewable feedstock, simple isolation or crystallization, and good biodegradability.
How does L-Menthol work chemically?
The molecule is a chiral monocyclic terpene alcohol, typically supplied as white crystals with a melting point around 42 to 44°C and good solubility in alcohol and oils but limited solubility in water. Use levels vary widely by product type, often around 0.05 to 1% in personal care, and formulators manage volatility, crystallization risk, and sensory intensity when pairing it with fragrance, flavor, or other cooling agents.
